Publisher: 2013Dissertation note: Intestinal resection and anastomosis is frequently essential during abdominal surgeries. Indications for intestinal resection are malignancy, inflammation, stricture formation, injuries and ischemia. Several surgical situations necessitate the resection of intestinal segments and the formation of consistent anastomoses. Conventionally, a large diversity of suture materials has been used to make hand-sewn anastomoses. Surgical stapler was made for the first time at the beginning of 20th century but its use remained limited in gastrointestinal surgery. Currently, stapled anastomoses is an essential part of the majority of the gastrointestinal surgeries. The simple-interrupted, single-layer, approximating technique, in which absorbable monofilament suture material is used, is presently believed to be the technique of choice for end-to-end bowel anastomosis. This procedure is mostly used in gastrointestinal surgeries with comparatively lesser complications. Intestinal anastomosis with skin staples was started by military surgeons for the soldiers suffering from bowel trauma caused by gunfire. In this technique, stainless steel skin staples were used to create a seromuscular intestinal anastomoses. There are several types of staplers available in markets, e.g. circular ligators, clip appliers, endoscopic staplers etc. The circular stapler is a disposable anastomotic instrument that places a round, double staggered row of titanium staples connecting intervening tissues. It can generate an end-to-end, end-to-side, or side-to-side anastomosis. This round stapler is available with a variety of staple line diameters to be used according to need. In current years, there has been a large shift from hand-sewn method towards the use of intestinal stapler in gastrointestinal surgery. They present a possible reduction in operational timing and are easy to learn and use than for hand-sewn method. So, staplers are very popular in the trainee. This research project was tested on 12 mongrel dogs divided randomly into two different groups (A and B). Each group comprised of 6 dogs. Conventional hand-sewn method of end-to-end anastomosis was applied on group A and stapled anastomosis was made in the dogs of group B. Two surgical techniques were applied for end to end anastomosis of jejunum. In group-A conventional hand-sewn anastomosis technique was applied. In this method a piece of jejunum was removed and then anatomosed with simple interrupted, single-layer, approximating technique. The absorbable, monofilament suture material was applied manually. This is currently considered the method of choice for end-to-end intestinal anastomosis in small animal surgery. This technique is well described and has been used throughout the canine gastrointestinal tract with a relatively low complication rate. In group-B a circular mechanical stapler was used to construct anastomosis. In this method a piece of jejunum was removed and end-to-end anatomosis was made using a mechanical stapler. Comparison of both techniques was made on the basis of clinical parameters (temperature, pulse, respiration, vomiting, diarrhea and blood in feces), radiographic evaluation, exploratory laparotomy, change in lumen diameter and duration of surgical procedure. There is a significant difference in change in diameter within each group before and after surgery but there is no significant difference in change in diameter or stenosis formation between these two groups. There is a significant difference in the duration of operation; stapled group significantly requires an average of 10 minutes less than conventional hand-sewn method. Conclusively it was inferred that there is no significant difference in change in diameter between stapled group and hand sewn group but the anastomosis construction time is shorter in stapled group. Stapled anastomosis is safe and faster technique than hand-sewn method. The prevalence of low complication rate makes it all the more ideal for application in routine practices.

Publisher: 2013Dissertation note: Coccidiosis is one of the most economically important parasitic diseases of small ruminants and infection may cause subclinical production losses to sheep and goat industry.Coccidiosiscause a serious threat to livestock productivity, due topoor feed utilization, stunted growth, poor weight gain, associated morbidity, mortality, and cost of treatment and control measures. The disease is worldwide in distribution and is caused by many species of Eimeria which invade cells of intestinal epithelium. To treat and control coccidiosis in sheep and goats, numerous drugs were found to be effective including Amprolium, Toltrazuril, Decoquinate, Diclazuril and Sulphadimidine.
The present study was conducted to determine the prevalence of coccidiosis in Dera Ghazi Khan, for this 752 fecal samples (376 from sheep and 376 from goats) were collected and examined through direct smear method and salt flotation method. Overall prevalence of coccidialinfection was 48.67%, with prevalence of 52.92% for sheep and 44.41% for goats. The prevalence of coccidiosis in sheep was significantly higher (P<0.05) compared to goats. Eleven Eimeria species were identified 6 from sheepand 5 from goats. In sheep the common Eimeria species wereE. ovinoidalis(56.78%), E. ahsata(47.23%), E. parva(35.67%), E. intricate (30.15%), E. faurei(26.63%) andE. pallid (19.09%). In goats the prevalent species wereE. ninakohlyakimovae(68.86%), E. alijevi(59.88%), E. arloingi(53.29%), E. caprina(46.70%) andE. hirci(22.15%). Eimeria infection was significantly high (P<0.05) in female (54.57%; 310/568) compared to male (30.43%; 56/184).The prevalence of coccidiosis was significantly higher (P<0.05) in ?6 month as compared to above 1 year age.A significant difference was found in three feeding systems (i-e) in stall feeding, grazing and both (grazing + stall) feeding system.Coccidiosis was significantly high (P<0.05) in animals with poor and week body condition compared to medium, good and fat animals. A strong association (P<0.05) was observed between fecal score and prevalence of Eimeria infection. Peak prevalence was observed in month of August (68.08% and 60.63%) while low in October (38.29% and 30.85%) in sheep and goats, respectively.
In present study threeaniticoccidial drugs were used and the percent efficacy of Furazolidon, Sulphadimidine and Amproliun was 96.34, 95.40 and 98.08 percent, respectively at day 7. Whereas 98.58, 98.03 and 99.55 percent,respectively at day 21.It was concluded from the results that there was no significant difference (P>0.05) among the percentage efficacy of Furazolidone, Sulphadimidine and Amproliun used in these trials.
Hematological analysis was performed using Automated Hematological Analyzer. Hematological analysis showed a significant reduction (P<0.05) in total erythrocyte count (TEC) and hemoglobin (HB) content due tococcidiosis. Results show a significantincrease (P<0.05) in TLC, MCV and PCV of infected animals as compared to control negative. Mean lymphocytes, Monocytes, MCHC and MCH counts were also decreased in infected animals. Hematological values of treated animals become normal at day 21stafter treatment.

Publisher: 2013Dissertation note: Bovine coccidiosis-is an infectious-disease affecting cattle and buffaloes resulting in great economic losses to the beef and dairy sector all over the world. Coccidiosis is an intestinal disease and usually associated with poor growth, bloody diarrhea and sometimes death of young animals. As bovine coccidiosis is commonly found in cattle and buffaloes, therefore it severely affects the production of milk and beef in Pakistan.
500 fecal samples-were collected (250 from-cattle and 250 from buffaloes) randomly to investigate the prevalence of coccidiosis in River Ravi Region Lahore. Overall prevalence of coccidiosis was recorded 57.2 % and 58.8 % in cattle and buffaloes, respectively. Slightly high prevalence was found in female animals. Highest prevalence (66.66% and 70.31%) was observed in animals below 6 months of age, while lowest (44.87% and 48.91%) prevalence was found in animals above 1 year of age in cattle and buffaloes, respectively. The study further revealed that highest prevalence occurs in August, followed by September and October while lowest prevalence was observed in July. The infection rate was a little high in crossbred (59.26 %) and Sahiwal cattle (57.89 %) as compare to imported breeds. Seven Eimeria species were identified from fecal-samples of cattle while Six species were identified from buffaloes, where E.bovis and E.zurnii were found most prevalent among them. Coccidiosis was prevalent significantly higher (P < 0.05)-in animals housed in confined-and dirt yard (72.13 % in cattle, 74.13 % in buffaloes) as compare to animals housed on paved (58.49 % in cattle, 61.22 % in buffaloes) and those having outdoor access. Coccidiosis was most prevalent in stall fed (71.64% and 73.68 %) as compare to grazing (28.58% and 31.91%) cattle and buffaloes. Highest (73.07 % and 72 %) prevalence was found in animals with Poor body condition (score-1), while animals with body condition score 3 (Good) were found with lowest prevalence (37.5% and 47.76%). Highest (82.35 % and 84.21 %) prevalence was found in diarrheic while lowest (36.19 % and 42.85%) prevalence was observed in animals with normal fecal score (1) both in cattle and buffaloes, respectively.
Efficacy of different chemotherapeutic agents against coccidiosis in buffalo calves was also determined in current study. Non-significant difference-(P > 0.05)-was observed-in percentage efficacy of all three anticoccidial drugs at day 28 onward, i.e. 100 % for Amprolium (Amprovil), 99 % for Furazolidone (Furasym) and 99 % for Trimethoprim+Sulphadiazine (Trisym). All the three drugs showed satisfactory results against coccidiosis in buffalo calves and no toxic effects were found during and after treatment.
The current study also determined the effects of coccidiosis on various blood parameters of buffalo calves. A significant reduction in Total Erythrocytic Count (TEC), Hemoglobin concentration, PCV, MCH, MCHC and statistically significant increase-(P < 0.05) in TLC, DLC (except Lymphocytes) and MCV was observed in infected animals. Also a statistically significant difference-(P<0.05)-was observed in mean hematological-values of infected not-treated and treated animals at day 28, where treated groups showed an improvement to the normal values.

Publisher: 2013Dissertation note: Trypanosomiasis is an infectious malady of equines characterized by weight loss, anemia, progressive paresis, enlarged lymph nodes, petechiae of serous membranes, conjunctivitis, edema of the legs and lower part of the body, urticaria, and alopecia. Considering the significance and utilization of equines in our country and the substantial losses rendered by trypanosomiasis, the present study was designed to study prevalence and chemotherapy of trypanosomiasis in equines of Gujranwala and Sialkot districts.
For this purpose, 300 equines (horses=100; mules=100; donkeys=100) were examined for Trypanosoma infection. The blood was collected by ear-tip puncture and from Jugular venipuncture. Then thin blood smear slide was prepared and dried up in air and stained with Geimsa's staining method and examined under microscope. T. evansi was identified by their morphological characteristics as described by Smyth, (1996). Overall prevalence of T. evansi in equines was estimated as 13%. Individually there were 16%, 13% and 12% prevalence of T. evansi found in horses, mules and donkeys respectively.
The effect of trypanosomiasis on various blood parameters (Hb, ESR, TEC, TLC, DLC, and PCV) was determined in 30 equines (horses=10; mules=10; donkeys=10). The remarkable decrease in Hb, TEC, PCV, and lymphocytes were observed. The value of ESR increased, while there were no remarkable changes in TLC, monocytes, basophils, neutrophils, and eosinophils.
For chemotherapy, 36 equines (horses=12; mules=12; donkeys=12) positive for trypanosomiasis, were divided into three groups (A, B, and C). Each group was further subdivided into three subgroups, comprising of 4 animals in each subgroup. The animals of group A (horses=4; mules=4; donkeys=4) were treated with diaminazine aceturate (Fatrybanil®, Fatro, Pakistan) @ 3.5 mg/kg BW I/M, and the efficacy of drug was found 83.3% in equines against trypanosomiasis. The group B (horses=4; mules=4; donkeys=4) was treated with isometamedium chloride (Trypamidium Sumarin®, Merial, Pakistan) @ 0.25 mg/kg BW I/M alone, and was observed 91.6% effective. While the group C (horses=4; mules=4; donkeys=4) was treated with Auk (Calotropis procera) @ 0.3mg/kg BW, 8 doses at alternate days (local treatment), which was found 41.6% effective. The efficacy of drugs was measured on the basis of disappearance of clinical signs and recovery rate of the animals, and blood smear examination at day 2, 4, 6 and 10 of post-medication.
Finally, the data on prevalence of trypanosomiasis was estimated by Pearson's chi-square test for significance whereas data on haematology was analyzed by Student's T-test using statistical software package STATA 9.1 (College Station T×77845, USA), P < 0.05 was considered significant.
Considering the significance and utilization of equine in our country and the substantial losses rendered by trypanosomiasis, the present project was designed to check prevalence and chemotherapy of trypanosomiasis in equines of Gujranwala and Sialkot districts. The results of this study will help farmers and veterinary practitioners in field.

Publisher: 2013Dissertation note: In vitro study was carried out in order to estimate the anti-theileria effect of Calotropis procera and Peganum harmala. Water and chloroform extracts of each plant were used in-vitro study along with standard drug Buparvaqoune (Butalex®). For this four concentrations i.e.4, 8, 12 and 16mg/ tested solutions of each extracts of each plant were applied on cultured lymphocytes exposed to theileria parasite infection. ELISA reader findings showed that the mean OD were found less in treated theileria infected lymphocytes cell culture as compared to untreated culture wells mean OD values. The highest cell reduction (94.36%) with C. procera chloroform extract treatment was observed at a concentration of 16 mg/ml solution. Lowest concentration (1mg/ml solution) of C. procera chloroform extract reduced non-significant (P>0.05) lymphocytes cell proliferation (40.97%) as compare to control negative group. P. harmala water extract was effective against the theileria parasite as significantly lower (P<0.05) mean OD value (1.802 ±0.341) was measured at a concentration of 4mg/ml solution and maximum inhibitory effect (92.20) was seen at a concentration of 16 mg/ml solution. ELISA reader findings showed that P. harmala chloroform extract treatment failed to inhibit lymphocytes cells propagation even at highest concentration. The highest inhibitory effect (85.33%) against theileria infected lymphocytes propagation was seen at a concentration of 16 mg/ml solution.
Plant extract was evaluated in respect of feed intake in rabbits. It showed that when administered extracts of C. procera in rabbits at dose of 3 mg and 5 mg/kg body weight, did not affect on feed intake in rabbits. However the chloroform and water extracts of both plant i.e. C. procera and P. harmala when were administered in rabbits parentally at dose 10 of mg/kg body. It showed that the feed intake of rabbits was non-significantly reduced as compared to other treatments groups. Hematological parameters such as WBC X103 count, RBC X 106 count and Hb g/dl values were measured at various days. Findings showed that significantly lesser RBC X 106 count was in group A3 and D3 than control at day 30 of experiment. A non-significant difference (P>0.05) was seen in RBC X 106 count and Hb g/dl measurements in all treatments groups. Kidney and liver functions were evaluated by measuring biochemical parameters, uric acid, creatinine and ALT at 0 days, 9 days and 30 days. Findings showed that serum creatinine and urea enzyme levels were significantly higher (P<0.05) in group A3 as compare to control group at day 30 of experiment. Serum level of urea was also significantly higher (P<0.05) in group B3 and D3 at day 30 of experiment. A non-significant difference (P>0.05) was seen in ALT in all treatment groups at day 30 than control. Post-mortem was performed at day 30 of experiment. Gross lesions consisting of hemorrhages, congestion, and lung emphysema were seen in rabbits treated with high dose i.e. 10 mg/kg of both extract of C. procera. Rabbits treated with P. harmala chloroform extract at dose 10 mg/kg showed moderate gross lesions. Histopathology of organs such as lungs, kidney, liver and heart was performed. Toxicity lesions were seen in rabbits treated with high dose i.e. 10 mg/kg of both extract of C. procera. Rabbits treated with P. harmala chloroform extract at dose 10 mg/kg showed histopathological lesions in lungs, liver and kidney.
Theileria infection was studied in vivo by developing through theileria infected Hayalomma ticks in crossbred calves (n=30) through. At day 15 of infection maximum increase in mean rectal temperature (105.24 ± 0.46F) was observed, twenty four calves had pyrexia (104.1- 105.6 F) and six claves were showing pyrexia > 105.6 F. A significant increase (P<0.05) in pre-scapular lymph node enlargement score of challenged calves was seen by day 7 of infection and maximum lymph node score (grossly enlarged size) was noticed in twenty calves (Table 4.14 , Plate 4.16) with peak mean score (2.73±0.44) on day 13 of infection. The piroplasm peak score (3.80±0.83) was observed in challenged calves at 22 day of infection and remained significantly higher (p<0.05) (2.60±0.54) in untreated calves until the 36 day of infection (Fig.4.29 and Table 4.16). A significant increase (P<0.05) in mean schizonts was observed in pre-scapular lymph node biopsy smear from day 7 of infection to onwards. Blood samples of challenged calves (n =30) were confirmed theileria positive through PCR test. The amplification of Theileria species were amplified at 1098 bp (Plate 4.20 and Theileria annulata was amplified at 721 bp (Plate 4.21).
In order to estimate the pattern of disease severity, severity score was measured by summation of mean score of piroplasms, schizonts, lymph node swelling and rectal temperature. From day 7, mild response (3-5 score) was seen in infected calves (n=10).
With increase in the severity of disease a significant decrease (P<0.05) was observed in mean values of the Hb g/dL amount, WBC and RBC count, Hct (%) concentration and lymphocytes percentage from day15 of infection onward to 36 day of infection. A non-significant decrease (P>0.05) in the mean values of MCH pg was seen throughout the experiment. A significant decrease (P<0.05) in mean values of MCHC g/dL along with significant increase (P<0.05) in the mean measurement of MCV fL (64.14±3.53) values was seen at day 36 of infection as compare to day 0 values, indicating macrocytic hypochromic anemia in challenged calves. These findings showed a significant increase (P<0.05) in excretory products (uric acid and creatinine) from day 15 of infection and onward as compared to day 0 values, indicating damaged kidney in infected calves. Biochemical analysis showed the significant increase (P<0.05) in liver enzymes (ALT, AST) from day 15 infection and onward.
Anti-Theileria activities of drugs were estimated by evaluating clinical manifestation of the disease and parasitological findings. Beside this treatment effect on hematological and biochemical reactions of liver and kidney functions was determined. A significant difference (P<0.05) in rectal temperature of calves groups (B and E) was observed than control positive (group F) at day 21 of post-treatment. On other hand calves treated with treatments A, C and D had a non-significant difference (P>0.05) in rectal temperature compared with untreated calves (group F). It was found that calves (n=5) dosed with C. procera chloroform extract (group A) had rectal temperature in normal range by the day 7 of post-treatment. Similarly calves (n=5) treated with Butalex were found with normal rectal temperature from the day 7 of pos-treatment. On other hand, at day 21 of treatment 40%, 20%, 40% and 80% calves were found with pyrexia in treatments groups B, C, D and F, respectively (Table 4. 46).
By the day 14 of treatment, calves of treatment groups B and E showed no parasitemia (piroplams ?1). Disease severity was estimated on accumulative score of rectal temperature, lymph node swelling and parasitological findings (piroplasms and schizonts score). It was found a significant decrease (P<0.05) occurred in the disease severity of score of disease in calves of groups B and E as compare to A, C and F at day 3 of post-treatment. At day 21 of treatment all treated calves were recovered from anemia.

Publisher: 2013Dissertation note: The background of this study is that world health organization (WHO) reports that neurological disorders affect one billion people worldwide, including 50 million affected by epilepsy. Epilepsy is a common neurological disorder characterized by recurrent, periodic, spontaneous and unprovoked seizures. Childhood absence epilepsy (CAE) is an autosomal dominant disorder and a heterogeneous familial condition in which family members express absence seizures initially, and then show multiple phenotypes of myoclonic epilepsy including partial or absence seizures and generalized tonic conic seizures. Molecular genetics techniques have identified various CAE associated mutations in many genes i.e. ion channels (CACNA1H, CACNA1G, CACNA1N), sodium channel genes (SCN2A, SCN1A, and SCN1B) and some GABA receptor genes (GABRG2 and GABRD). CACNA1H ion channels are the principal intermediaries of fast neurotransmission in the CNS and have been frequently reported to play a significant role in a number of seizures. CACNA1H gene encodes the alpha (?) subunit and is usually located in post synaptic.
Various parameters are used in the present study was aimed to investigate coding regions of CACNA1H gene for analyzing the mutations involved in epilepsy. Blood samples of unrelated true representative of CAE were collected from psychiatry departments of different hospitals of Lahore. DNA were extracted with the standard protocol and amplifications of the CACNA1H regions were done with specially designed primers.
Later on, analysis of the results is done by sequencing of target fragments is carried out. Sequences are analyzed through BioEdit software and then aligned with the help of clustalW2 software.
It has been identified by the recent study on the absence epileptic patients of Pakistan that the gene CACNA1h has SNPs in the exon 9 and 10 at the position (2025G>A) and (4867 G>T) respectively which eventually alters the protein, making it hyperactive as the mutations are in the sensor regions of the protein, thus giving a 'gain in function' property to the ion channel.
In the conclusion, we must say that further study, with much larger sample number, is required to revise the effects of this polymorphism and accurately identifying the associated factors. There is a need to explore the other gene mutations causing epilepsy in local population of Punjab and Pakistan that will ultimately help to develop genetic counseling strategies, gene therapies and prenatal diagnostic procedures for the population of Pakistan.

Publisher: 2013Dissertation note: Cystic hydatid disease has a worldwide distribution. Echinococcusis cause great economic loses in Pakistan and lead to the loss of worth 276.20$ per 100 sheep and goats, as well as 165.72$ per 100 infected buffaloes, cattle and camels. It has zoonotic importance and also have well-recognized zoonosis in Pakistan and numerous cases have been reported in the medical literature. Cystic hydatid disease is caused by Echinococcus granulosus, (E. granulosus), tapeworms. Adult tapeworms of this specie are small in size. Their measurement revealed that they reach upto 2-11 mm in length and contain protoscolex, the cephalic end for attchment and 2-5 proglottids segments. Two rows of keratinized hooks and four number of suckers are present on scolex. The last gravid proglottids segments bear the large number of fertilized eggs, which are shed after every 7-14 days. Eggs are oval in shape, having clearly distinct oncophore and 30-36 micrometer in diameter. There are several different strains of E. granulosus, which are genetically distinct. These strains vary phenotypically and therefore, this feature can be used for the control of this parasite. 10 genotypes of E. granulosus are identified up till now. Therefore, in this study we used PCR technique for prevalence determination and molecular characterization of specific strain of E. granulosus. The primers specific for E. granulosus were used in this study. The E.g.ss1for (5¡Ç-GTA TTT TGT AAA GTT GTT CTA-3¡Ç) worked as forward primer, while E.g.ss1rev (5¡Ç-CTA AAT CAC ATC ATC TTA CAA T-3¡Ç) worked as reverse primer. For this purpose, total 200 numbers of cyst samples (100 from each district) were collected from liver and lungs of cattle, buffaloes, goats and sheep slaughtered at different private and public abattoirs in Okara and Jhang. An antimortem examination was performed on each animal
LIV
and data regarding each animal entered in data capturing form before slaughter. Whole cyst sample was collected without rupturing and preserved in ice packs. Then these isolates were transferred to laboratory and stored at -20 ¢ªC for further processing. For the genetic analysis of E. granuous (Hydatid cyst) DNA was extracted from germinal layer and cystic fluid by using DNA extraction reagent (TRIREAGENT¢ç, Molecular Research Center, Ohio, USA) according to the manufacturer.s instructions. PCR was carried out by using primers specific for G1 strain of E. granulosus. The whole three steps (Denaturation, Anealing, Amplification) of PCR was carried out in PCR thermo cycler under conditions specific for E. granulosus. The final PCR product was electrophoresed in a 1% agarose gel containing 0.5 ug/ml of ethedium bromide. Electrophoresis was completed by applying 90 volts for 40 min. After required time, gel was placed in UV trans-illuminator to visualize the band shown by specific genotype of E. granulosus. Specific bands at 254 bp confirmed the G1 strain of E. granulosus. Results indicated the prevalence of 37% in Okara and 65% in Jhang district of Punjab. While in cattle (58.00%), buffalo (76.00%), sheep (36.00%) and goats (34.00%) prevalence was observed. As well as, (44.7%) prevalence of E. granulosus was calculated in liver and (54.8%) was observed in lungs in both districts. So, this study predicted the prevalence of hydatid cystic disease in ruminants in Okara and Jhang. PCR technique was used for the diagnosis of hydatid cyst in animals. This molecular characterization technique enables us to know the specific strain of E. granulous existing in these two districts. Finally the data gathered from this study help to understand the disease structure and to develop future plan.

Publisher: 2013Dissertation note: There were one hundred cases of dogs showing the clinical signs of canine parvovirus infection like bloody diarrhea, vomiting and emaciationwhich were selected randomly. All the cases were confirmed by HA and HI test. Disease occurrence was found to be 55%. There were 55 samples found to be positive and 45 samples were found to be negative for canine parvovirus. The incidences of the disease in German shepherd was highest (38%) followed by other breeds Labrador, Rottweiler, Pointer, Cross, Russian and Local breeds which were 8%, 7%, 6%, 5%, 4% and 3% respectively. Similarly, disease occurrence in non-vaccinated dogs was higher thanvaccinated.The disease was more prevalent in non-vaccinated dogs as compared to the vaccinated dogs. So, vaccination provides sufficient immunity against canine parvovirus. Male dogs were more affected by canine parvovirus than female dogs. Occurrence of the disease in the age of 1-3 months was the highest. Pups were more affected than the older dogs. Occurrence of canine parvovirus in the male and female were found to 60% and 43.5% respectively. Disease occurrence of canine parvovirus in September, October and November was found to be 55%, 52.5% and 56% respectively. Blood samples were collected at day 0(before the treatment) and on the day 5 (after the treatment) and analysis was done in UDL, Lahore. Four different kinds of treatment protocols were compared on the basis of hematological improvement, days of hospitalization and the cost of treatment. Of the four groups hyperimune serum when used with normal saline was found to be more effective. It was found that improvement in the leucocytes, neutrophil, lymphocyte, monocytes and platelets with P <0.05. SAFI syrup with supportive therapy was the second effective treatment with P >0.05. Supportive treatment alone was not effective for hematological recovery P > 0.05. It had also increased the cost of treatment, and duration of treatment for canine parvovirus infection. So, hyper immune serum and normal saline is the effective treatment for canine parvovirus infection.

Burden Of Endoparasites In Ruminants In Live Aimal Markets Of Lahore
by Faiza Afzal | Dr. Jawaria Ali Khan | Dr. Aneela Zameer Durani | Prof. Dr.
Material type: ; Format:
print
Publisher: 2013Dissertation note: Endoparsites cause severe economic losses by affecting and may cause many diseases to animal. Due to anthelmintic resistance and poor managemental practices endoparsitic disease are more common now a days. In Pakistan parasitic infestation is quite prevalent and the loss about 26.5 million rupees annually to the livestock industry. Although no exact figure of economic losses is available but it is fact that millions of rupees are being lost due to reduced milk yield, rejection of meat and edible offal, depreciation of hides, delay age of maturity and death particularly in calves and high production cost due to use of drugs, they also decrease feed intake efficiency. Present study was conducted to check the burden of endoparasites in different live animal Markets of Lahore, For this purpose 800 samples of large ruminants (cattle, buffalo) and small ruminants (sheep, goat) were collected and transported to lab for further qualitative fecal examination through macroscopic and microscopic examination. In six live animal markets overall prevalence of endoparasites found 21.37%. Out of 800 samples 171 were found positive. Prevalence of large and small ruminants was found almost similar i.e: 21.5%, 21.25% respectively. However much parasitic burden was observed 43.1% in cattle to that of 28.1% in buffalo.Prevalence in sheep was high as compared to goat whereas kacchi breed of sheep and Desi breed of goat showed higherprevalence that as 14.5%, 16% respectively.Prevalence in Nilli ravi was 28.0% in non-exotic cattle it was 31% however in exotic jersey breed prevalence of endoparasites was 11%. Endoparasites found more prevalent in Nilli Ravi. In ruminants prevalence found high in male animals as compared to female animals. Overall prevalence in ruminants was 21.0% while in male and female animals prevalence was 21.8%, and 20% respectively. prevalence found more in less than 1 year aged animal than above this age i.e, in less than 1 year of age was 22.4% prevalence while above 1 year aged animals it was 20.0% (P<0.05 ). In large and small ruminants nematodes were more prevalent followed by trematode, cestode, protozoa, and mixed infection. Among nematodes haemonchus were found more prevalent gastrointestinal parasites. Out of 171 positive samples 46 were of haemonchus (5.75%) followed by ostertagia 18 (2.25), trichostrongyloids 17(2.12), cooperia 8(1.0%), bunostomum 6(0.75%), trchuris 11(1.37%), oesophagostomumm 5(0.5%), in large ruminants. Small ruminants also found chabertia ovine 1(0.0125%) and strongyloid papillosus 1(0.0125%) infestation. During this study overall prevalence of Nematode, trematode, cestode, protozoa, and mixed infection found 15.0%, 3.5%, 1.875%, 0.625%, and 0.25% respectively. Mixed infection only found in live animal market 1 at Multan road. In live animal Market 2 at Sagyan Bridge only nematode and trematode were present. In live animal Market 3 at shahpur kanjran no mixed infection was found. And protozoa were only found in large ruminants. In live animal Market no protozoa and mixed infection was found. In live animal Market 4, 5, 6 no protozoa and cestode found. The data obtained was analyzed through chi -square test (SPSS) and probability level of <0.05 was considered as significant different. As results show ( p< 0.05) data was considered as significantly different. Fascioliasis, parasitic gastro-enteritis, coccidiosis, theleriosis, and babesiosis are major parasitic problem in ruminants in order to priority. There is urgent need to carry out research on applied aspects leading towards control of parasites. This parasitic research has been focused on a limited part of country. This should extend in broader area keeping in view various agro-ecological zones of country.

Aqueous Garlic Extract (AGE) + Sodium Thiosulphate (ST) (Group 29)
A group of 6 mice in this group were treated with AGE at 750 mg/kg and ST at 600 mg/kg intraperitoneally (i.p) and righting reflex recovery time was recorded.
Sodium Nitrite (SN) + Sodium Thiosulphate (ST) (Group 30)
A group of 6 mice in group 30 were treated with SN and ST at 20 mg/kg and 600 mg/kg intraperitoneally (i.p) respectively and righting reflex recovery time was recorded.
The efficacy of the antidote estimated was based upon the reduction in righting reflex recovery time.
The righting reflex recovery time that was close to 1 hour was determined against KCN regimen. AGE was tested as potential antidote against sub-lethal KCN toxicity at dose regimens 250, 500 and 750 mg/kg intraperitoneally as well as orally at dose regimens 250, 500 and 750 mg/kg 5 minutes before and 5 minutes after KCN administration. SN and ST were tested at 20, and 600 mg/kg respectively as antidotes against sub-lethal KCN toxicity, 5 minutes before and 5 minutes after KCN administration. These were also tested in comparison and a dose with minimum recovery time was noted. A comparison was made between the efficacy of AGE and SN or ST or SN + ST as potential antidote against sub-lethal KCN toxicity. After 48 hours 3 mice from each group was sacrificed for postmortem examination.
For this purpose the righting reflex recovery time and survival data was collected for each mouse challenged with KCN. A group of 3 mice was tested with each increasing dose of KCN to create dose response curves for both righting reflex recovery times and percent survival. Increasing doses of KCN increased the recovery time of the righting reflex. The dose 5.5 mg/kg of KCN showed the righting reflex recocery time mean 64.66 ± .333 min and was selected for trials.
AGE (750 mg/kg) showed the most significant results as compared to ST and SN alone as well as in combination. Second most effective drug was ST as it showed better results than SN. Treatment results were more pronounced in 5 min pre-KCN groups as compared to 5 min post-KCN groups.
From this study it was concluded that the aqueous AGE is an effective antidote against sub-lethal KCN toxicity as the recovery times indicated that its effects are more pronounced than SN and ST, secondly, as it is easily available and very much cheaper in Pakistan and due to easy unavailability of SN and ST, it is effective antidote that could be used in the field against sub-lethal KCN toxicity with comparatively better results both orally and intraperitoneally.

A Study On Medetomidine And Alpha-2 Adrenoceptor Agent Alone And In Combination With Other Anesthetics On Different Animals
by Hamid Akbar | Prof. Dr. Mohammad Arif Khan | Prof. Dr. Mohammad Sarwar Khan.
Material type: ; Format:

; Literary form:
not fiction
Publisher: 2013Dissertation note: Medetomidine HCl (alpha-2 adrenergic agonist) is a highly potent sedative and analgesic drug being used extensively in veterinary practice. It produces reliable degree of sedation, muscle relaxation and analgesia in different animal species.
Hypothesis:
On the basis of existing knowledge about medetomidine HCl it is hypothesized that medetomidine anesthesia alone as well as in combination with other anesthetics can overcome the prevailing hazards of different anesthetics.
Goals:
The goals of study were to investigate clinical suitability of "Medetomidine HCl" an alpha-2 adrenoceptor agonist drug alone and in combination with other drugs in different animals. A detailed clinico-biochemical study was carried out to explore the various aspects of this novel sedative and analgesic drug in different animal species. Analgesia was evaluated by checking presence and absence of various clinical reflexes and by performing certain surgical procedures under experimental conditions. Different experiments were designed in different animals to investigate the sedative and analgesic properties of medetomidine HCl. In dogs a clinico biochemical study was designed to see effect of this drug on clinical and hematological parameters at different doses alone and in combination with gas anesthesia. In equines the combination of this drug with other routinely used sedative and analgesic drugs was evaluated. In another study in bovine calves the epidural effect of this magic drug was evaluated. In cats this drug was evaluated in combination with Ketamine during major surgical intervention.
Methodology:
The parameters used to evaluate analgesia revealed that Medetomidine has greater potential to lessen the pain during minor and major surgical interventions in different animals. However, its epidural use also produced good analgesia of perineal region and at higher doses used epidurally its results can be compared with lignocain which is an ideal local anesthetic agent. Medetomidine produces general sedative effects after absorption from epidural space into general circulation. It was proved that in equines the drug can be used in combination Propofol, Ketamine and chloral hydrate for ideal sedative and analgesic effects and it compensated the side effects offered by these drugs when used alone. In addition it has an edge over other sedative drugs on account of its undetrimental effect on various physiological parameters of the animals. Detailed Clinical and hematologic studies have proved that Medetomidine "a novel sedative and analgesic" is the drug of choice for restraining, examination, minor and major surgical manipulations in equine, bovine, feline and canine species and it produces minimum untoward effects.
This study will definitely open the new horizons to choose good anesthetic agents alone or in the form of cocktail to minimize the hazards of conventional drugs to save the economics of country. Medetomidine was used in four different animal species (equine, bovine, canine and feline). In canine the drug proved to be an effective sedative and analgesic drug aone and in combination with volatile anesthetic giving anesthetic sparing effects and exerted minimum effects on clinical and hematological parameters. In felines medetomidine effectively replaced an older and commonly used drug xylazine for combination anesthesia for surgical interventions. In bovine the drug was used as epidural anesthetic and proved to give ideal local effects. In equine medetomidine HCl was used effectively in combination with other anesthetics and enhanced sedation, analgesia, induction, recumbancy and recovery paramerts. A prolonged and stable recumbancy period enables the surgeons to carry out major surgical interventions smoothly and without hazards. In past many drugs have been trailed in veterinary practice as sedative, analgesic and anesthetics like clonidine, xylazine and atipamazole but medetomidine HCl has replaced these drugs in terms of safety, efficacy and effectiveness.
In review of results of present studies it is recommended that medetomidine HCl can be used effectively for anesthesia in animals. In present study medetomidine HCl was trailed as anesthetic drug in different animals in variable experimental conditions and has proved to be an ideal sedative and analgesic. It can be used to handle different surgical conditions like suturing, removal of a tumour and cyst, to drain abcess, eye enucleation, roaring operation, cropping, tail docking, tenectomies, neurectomies, tracheostomy, dehorning and correction of prolapse. The drug can also be implied effectively alone or as preanesthetic in different major surgical interventions like evisceration, enterotomies, intestinal anastomosis, castration, penile amputation, spleenectomy ovariohysterectomy and cessarian section. In different experimental trails medetomidine HCl has shown its anesthetic efficacy alone and in combination with other drugs. It variably minimises the side effects and risk and dose rate of other anesthetic drugs used in combination. In addition the combination of medetomidine HCl prolonged the duration of surgical anesthesia and provided ideal analgesic effect. Anticipated difficulties were time frame for the conduct of trials and financial constraints faced which may have hampered clarification of some findings owing to the low number of animals in different groups this difficulty may be faced by future researchers especially in third world countries. Further studies and research could include effects of alpha-2 drugs for treating colic in equines and the evaluation of this drug in orthopedic surgery. And for Future research can be planned on muscle metabolic changes during and after anaesthesia in horses. With these techniques valuable information may be gained that would otherwise be overlooked. The present investigation was mainly undertaken to study the anesthetic role of medetomidine HCl in different animal species in order to deepen the understanding of physiologic and biochemical parameters during and after anaesthesia must be fully clearified. At the end there were some unanswered questions which can be effectively addressed if other aspects of this drug are studied. Some other aspects of medetomidine anesthesia need to be explored further in the future studies.

Publisher: 2014Dissertation note: Liver is the largest visceral organ in the body and has a paramount importance. Its multi-functional abilities make it absolutely necessary for survival. It performs numerous functions in a living organism and plays its role in various physiological and biochemical regulatory processes in the body. It is also the only organ that has the capability to undergo the phenomenon of regeneration in case of cellular injury induced by chemicals or surgery.
According to Craige (1948) Liver is the largest gland of the body. It is an extension of the gastro-intestinal track and connects with GIT to the common bile duct.It has two surfaces. The anterior or dorsal surface is convex while the posterior surface is concave and lies over the stomach. Liver is thickened in its dorsal portion and tappers to a thin ventral margin. The liver is incompletely divided into a right and a left liver lobe, each of which have anterior and posterior lobules. The right posterior lobule lies closely to the dorsal body wall and it accommodates right kidney in a depression called renal fossa. The gall bladder is a thin walled pouch located in a deep depression on the ventral surface of right anterior lobule. The quadrate lobe extends from the right lobe and is usually notched on its medial margin. The caudate lobe is small and well separated. The portal fissure is a large depression filled by the portal vein and it also contains some branches of hepatic artery. The liver is held in place by four ligaments namely falciform ligament, round ligament, coronary ligament and left triangular ligament.
According to Borley & Achan (2005) Liver plays a key role in several regulatory processes in an organism. It is involved in various metabolic pathways comprising variable interactions with proteins, carbohydrates and fats. Liver is the main site for gluconeogenesis, converts galactose and fructose into simple sugars (glucose) and stores complex carbohydrates (glycogen).It aids in the production of different types of proteins and has a role in the formation of urea. Numerous types of fats like phospholipids, cholesterol and lipoproteins are synthesized in the liver. Liver also uses different carbohydrates and proteins to form certain fats. Liver serves as a vault for the storage of several vitamins (A, B2 and D) and iron. It helps in the complex process of coagulation by aiding in the synthesis of several important coagulation factors including prothrombin, protein C, and factors VII, IX and X.Several hormones including oestrogen, aldosterone and cortisol are metabolized in the liver. It is involved in the metabolism of a number of drugs and also has a key role in the production and excretion of bile. In fetal life, haematopoiesis is one of the key functions which is performed by liver.
Liver resectioning is a technique employed for correction of numerous ailments or for the purpose of experimental study. Diseases such as tumorous growths on the liver, hepatic necrosis, cyst formation, hepatic abscess, hepatic lobe torsion and numerous others require the removal of the affected part of the liver(Martin et al. 2003; Pignon et al. 2013). The remaining liver usually recovers by regeneration through hyperplasia and hypertrophy of healthy cells of the un-affected part of the liver (Palmes and Spiegel, 2004). For experimental reasons, where different aspects of liver regeneration process are to be studied, liver resectioning technique is employed (Mao et al. 2014; Fausto et al. 2012).
Numerous studies have been done to see the regeneration rate of liver in different species. In rats it has been noticed that liver can regenerate to its original size after two-third hepatectomy in only five to seven days (Mao et al. 2014).Another author states the recovery to occur in less than two weeks in rodents (Gilgenkrantz and Hortet, 2011). In humans it has been shown that resectioning up to 50 percent has resulted in complete regeneration of liver mass in only a period of two weeks (Häussinger, 2011).
Rabbits being small laboratory animals with comparative ease of handling have been used extensively for research purposes. Regeneration has been studied in rabbits post chemical insult on liver or through portal branch ligations (Palmes and Spiegel, 2004).
As opposed to general perception, Carpenter (2003) states that the rabbits fall under the category of rodents, they in actuality are lagomorphs. Two families composed of twelve genera and eighty-one species fall under the umbrella of order lagomorpha. They are cosmopolitan in their distribution. The main difference between rodents and lagomorphs is the presence of two pairs of upper incisors in the former group, whereas the later have only one pair of upper incisors. Despite having a great degree of similarity which these two groups share together, they are not thought to be closely associated. The animals of both the categories evolved into nine creatures separately and their similar dental patterns resulted from parallel evolution. All legomorphs consume foliage and practice caprophagy.
All lagomorphs are blessed with acute tactile and olfactory senses with a considerable long-haired fluffy body coat. Lagomorphs have big side-to-side set eyes giving them a broader circular vision. Testes are in the scrotum in front of the penis. Baculum is absent in males. Females bear two to five pairs of mammary glands.
Deficiency has been observed in terms of study of liver regeneration when liver resectioning is performed. The present study aims to focus on this aspect of research on soft tissue, which would enhance our understanding of liver regeneration and its rate in this specie.

Publisher: 2014Dissertation note: Anesthesia is a reversible process and derived from Greek word “anaisthaesia” meaning “insensibility” and used to desensitize the whole or any part of the body. Anesthesia is classified by method of administration i.e. intramuscular, inhalational and intravenous. Injectable anesthesia includes Propofol, Diazepam, Acepromazine, Medetomidine, Xylazine and Ketamine. Anesthetic agent can be used alone or in combinations (Gonzalez et al. 2003).
The purpose of Anesthesia is to produce a convenient, safe, effective, and economical means of facilitating surgical procedures while minimizing stress, pain and discomfort and adverse side effects. There are many routes of administration of anesthesia; in intravenous route, the onset of action is immediate. Peak effect is rapidly obtained, duration of action is short, and effects are more intense/ profound than other routes.Many combinations of anesthesia are in use in dogs for different surgery xylazine (0.4 mg/kg IV) combination with butorpjanol (0.2 mg/kg IV), xylazine (0.4 mg/kg IV) combination with oxymorphone (0.05mg/kg IV) , xylazine (0.4 mg/kb IV) combine with morphine (0.25mg/kg) , Medetomidine (5 to 15 ug/kg combine with butophanol (0.2 mg/kg IV), Medetomidine (5 to 15 ug/kg IV) combine with oxymorphone (o.05 mg/kg) Xylazine (0.4mg/kg) combine with Ketamine (5 to 10 mg/kg IV) acepromazine (0.05 to 0.2mg/kg IV or SQ) in combination with morphine (0.4 to 0.8mg/kg IV) and diazepam or midazolam(0.2 mg/kg IV) with hydromorphone or oxymorphone( 0.1 to 0.2 mg/kg IV) use in dog and cat (Greene 1999).
Detomidine is a selective α2-adrenoceptor agonist with useful sedative, analgesic and muscle relaxation properties and is widely used as a tranquilizing or pre-anaesthetic medication in veterinary medicine But it induces cardiovascular side-effects such as hypertension, hypotension, bradycardia and dysrhythmia.detomidine. It produces prolonged and intense analgesia. Nature of the analgesic effect appears to be wide, producing a reduced response to be a secondary result of the central nervous system experimental stimulation and exhibiting a clinical effect in the horse with colic. Detomidine can be used as a safe and effective pre anaesthetic resulting in smooth induction and recovery (EL-Kammar et al. 2014).
Xylazine Hcl has been widely used as a preanesthetic drug and for immobilizing dogs for diagnostic procedures (Short 1987).Xylazine is the shortest acting alpha2-adrenergic agonist..A problem with alpha2-adrenergic agonists is that they may respond suddenly to stimulation, especially to touch. The combination of opioid drugs with the alpha2-adrenergic agonists appears to reduce such sudden reactions and a synergistic effect regarding sedation and antinociception has been suggested. Additionally, all alpha2-adrenergic agonists have a dose-dependent effect on cardiovascular function. By adding an opioid drug, dose requirements of alpha2-adrenergic agonists may be reduced and cardiopulmonary function improved. The addition of opioids does not further impair cardiovascular function.The combination of xylazine and butorphanol at the doses generally used in clinical practice produces minimal and transient haemodynamic effects and no significant respiratory depression. There is no ‘blinded’ randomized crossover study regarding the xylazine sparing effects of butorphanol on sedation of horses. There are limited reports on the respiratory effects of butorphanol alone or in combination with the α2-agonist xylazine in horses, but the effects of the combination on pulmonary gas exchange have not been clarified (Ringer et al. 2012).
Butorphanol is an opioid agonist-antagonist with good analgesic effects. Butorphanol is used in veterinary medicine as pain reliever and cough suppressant. It induces only mild sedation and has minimum adverse effects to the cardiovascular system. It may cause mild lowering of the heart rate and arterial pressure or slight respiratory depression. It exerts a depressive action on the respiratory system. It should not use in patient with liver disease because it cannot be eliminated and may accumulated to toxic level (Raušer and Lexmaulova, 2002).It is believed to be more effective against visceral rather than somatic pain. The antagonist property towards μ-receptors results in a ceiling analgesic effect with increasing doses. However in dogs doses between 0•2 and 0•8 mg/kg have been reported to provide visceral analgesia in vivo .Butorphanol is a dose-related respiratory depressant and causes small decreases in arterial blood pressure and heart rate (Vettorato and Bacco 2011).
Castration is indicated for reproductive neutering, modification of behavior patterns, testicular neoplasia, severe testicular or scrotal trauma or injury, refractory orchitis, benign prostatic hyperplasia, perianal gland adenoma, perineal hernia, and scrotal urethrostomy in dogs. There is no specific anesthetic method for castration. Routinely castration surgery can be performed under general anesthesia or local anesthesia (Kim et al. 2004).
Unlike other laboratory animals that are commonly used forresearch purpose, non-human primates and dogs are also used for research work. Their use in the biological researchrequires special considerations, regarding their care and housing, and more specifically their handling and restraining. Since non-human primates and dogs present special hazards to handlers, particularlybecause of the danger of bites and zoonotic infections (Fortman et al. 2001).
Deaths due to anesthesia are lesser in dogs (1 in 601) than rabbits (1 in 72) that are the third most commonly anaesthetized pet animal in the United Kingdom (Brodbelt et al. 2005).

Publisher: 2014Dissertation note: Livestock is one of the major sectors of Pakistan’s agrarian based economy. During 2013-14, it contributed almost 55.4% to the agricultural value added and 11.9% to national GDP. In the livestock sector, gross value addition increased from Rs.735 billion to Rs.756 billion; revealing an increase of 2.9% as compared to the previous year. Livestock is considered the best tool for poverty alleviation, as most of the livestock are owned by poor people who live in the rural areas. Pakistan is 4th largest Milk producing country in the World. Its Cattle Population is 33 Million while Buffalo Population is about 30 Million (Economic Survey of Pakistan, 2013-14). Despite large population, per animal production is very low.The low productivity of these animals is because of poor quality feed stuff. Their productivity can be enhanced by feeding them balanced ration.
Growing human population urges the intense need to explore the present livestock resources to fulfill the animal protein requirements. It is impossible unless optimal fodder and forage production is ensured. In Pakistan, low quality fodders coupled with the reduction in the fodder area are the main constraints, which adversely affect the animal production. In future, it is expected that ruminants will be more dependent on forages because readily expanding human population will have direct competition with livestock for edible grains.
Among the problems facing the livestock in the tropics is the low protein tropical grasses and the high cost of alternate sources of protein such as the Soybean and other oil cake. A portion of nitrogen in feeds for ruminants may be provided in the form of simple nitrogen compounds (or0non-protein0nitrogen0NPN) 0that are degraded in the0rumen to release ammonia (NH3), which is used by rumen microorganisms to produce amino acids. The amount of NPN that can be provided is limited. The product which is the urea, when it releases NH3 faster than it can be converted into microbial protein excess NH3is absorbed through the rumen wall, causing toxication.
Protein is often0the0major0limiting0nutrient for ruminants. Protein-rich leguminous forages and vegetable protein supplements are usually expensive or not available.The manufacture0of0urea and0ammonia for use as0fertilizer has been greatly0expanded in0many countries, 0but these compounds0could0not be0used more0widely in feeds for0ruminants. The ability0of0the0micro-organisms0in0the0rumen0of0cattle0and0sheep0to0utilize0urea0sources0to form0true protein0that0can0be converted0to meat0and0milk0by the0animals, represents0an important0contribution0to0man's0food0supply.0Maximizing0microbial0protein0synthesis0and flow0to0the0duodenum0by0reducing the0recycling of0microbial N in the rumen offers a potential0to improve0the production0efficiency0of ruminants.In general, the efficiency of utilization of dietary N by cattle is relatively low under normal production conditions (Castillo et al, 2001) with a global average N-efficiency in cattle estimated at 7.7 % (Van der Hoek, 1998). Urea is used rather inefficiently for production of protein products (Broderick et al, 2009) and due to its wide use in ruminant feeds, may0be0partially0responsible for0the poor N efficiency0in cattle. Low efficiency of utilization of dietary urea has been attributed to the rapid0hydrolysis0to0ammonia (NH3) in0the0rumen0by microbial0enzymes which occurs at a higher rate than its utilization byrumen bacteria, leading to ruminal accumulation and absorption0of0ammonia andsubsequent excretion of0urea in the urine (Golombeski0et0al., 2006; Highstreet0et0al,2010).Furthermore if used above threshold level, the main problem with urea usage is that it can cause toxicity and even death of the animals. Farmers hesitate to use urea as a source of protein, resulting which his animals remain underfed and never achieve the peak production.
Urea0poisoning0is0one0of0the0more0commonly0suspected0toxicities0of0cattle. Urea0is0used as0a source0of non-protein0nitrogen0in feed0supplements.In ruminants,0nitrogen0from0urea is released0in the0rumen as0ammonia0and0can0be0used0by0rumen0micro0flora0to0synthesize protein. This0protein0thenbecomesavailable0to0the0animal0through0the0normal0processes of digestion0and0absorption. However,if0 more0ureaisconsumed0than the rumen organisms can0metabolize, the0ammonia0is0absorbed0from0the0rumen0into0the0blood.Ruminal pHbecame alkaline due to the hydrolysis of urea to0ammonia (Buffalo Bulletin,2002). The ammoniaisthen0converted0back0to urea in0the liver and is0the0excreted by0the0kidneys. This0pathwaycan easily be0overwhelmed,0when excess0ammonia0and urea0circulate0in the blood,0causing0poisoning. Poisoningcanoccur0rapidly0from a few0minutes0to four0hours after0consumption. Suspect0urea0poisoning0if cattle are found0dead close to0the0supplement (H. Parkes et al. 2003).Slow release urea has been shown to affect ruminal fermentation characteristics.Most notably, slow release urea is intended to0reduce0the release rate0of NH3 within the0rumen. Most reports on controlled release urea have shown a reduction in ruminal NH3 concentration when measured (Cherdthonget al, 2011; Huntington etal, 2006b; Taylor- Edwards0et0al, 2009d). This is the reason why slow release urea presents a lower risk for ammonia toxicity than feed grade urea. Ruminal NH3 concentration is often related to ruminal pH, as the protonation of NH3 toNH4+ when ammonia from urea ionizes, can result in an increase in ruminalpH. Consequently, there are reports of higher ruminal pH for animals fed urea than those fed slow release urea (Cherdthongetal, 2011; Taylor-Edwards et al, 2009b)

Publisher: 2015Dissertation note: Dairy sector has significant role in Pakistan economy with a share of 46.8% in agriculture and 10.8% to Pakistan GDP. Pakistan ranks 4th among largest milk producing countries in the world (Anonymous 2012-13).In last decade, dairy sector in Pakistan has seen tremendous growth and corporate investment. More than 40000 exotic cross bred high producing cattles have been imported. Earlier this sector used to rely primarily on local low producing cattles and small scale subsistence farming, now different commercial dairy farms having high producers exotic cattles are also becoming major contributor in this sector. Trend is changing, different issues concerned with sector are rising. Sensitivity level of commercial dairy farmer is far high as compared to small scale traditional farmers, they can not accept or tolerate any factor affecting economy of their dairy business due to heavy investment.
One such issue rose to headlines in July-August 2014, Pakistan dairy industry was struck badly with an outbreak of viral disease called Bovine Ephemeral Fever (BEF). It caused colossal damages to dairy industry in terms of decreased milk production, mortalities and treatment costs. This was not an out rightly a new disease in Pakistan its episodes have been seen in past in local cattles and buffalo (Asi et al. 1999) and locally it was termed as “will” (Prof Khushe personal communication). But it never got such a hype and attention in past as local animals were already low producers and their production was never affected at substantial level. Local animals were generally weak having low Body Condition Score, a character which does not support the intensity of this disease, Ectoparasite resistance is another factor considered to be a source of protection for local animals.
Introduction

During initial phase of outbreak, it was considered as a common local epidemic Hemorrhagic Septicemia (HS) and Foot and Mouth Disease (FMD) and few signs also confused it with Milk Fever. But once outbreak progressed, it became clearer that it in neither HS and nor FMD it is something different. After going through literature it was clinically suspected as BEF and later was confirmed through Polymerase Chain Reaction (PCR) by University Diagnostic Laboratory (UDL), UVAS, Lahore.
BEF is a viral disease caused by genus Ephemerovirus and family Rhabdoviridae. (Uren et al. 1992).It is a noncontagious, vector borne disease of water buffaloes and cattles proposed to be communicated by midges (Culicoides biting) and mosquitoes.(Walker et al. 2012). Ephemeral fever, stiff sickness, three-day-sickness, bovine influenza and bovine epizootic fever have been used to name this viral disease in the different nations at different eras (Chiu 1986; Chiu and Lu 1986; Lin and Inoue 1969; St.George1981). BEF happens seasonally in temperate, tropical and subtropical regions of Asia, Africa, Middle-East and Australia and this is a disabling disease with significant economic effect due to reduction of milk production, loss of health status in beef herds, abortion and infertility. Characteristic clinical signs comprise of a sudden onset of fever as high as 41 °C, an abrupt and austere drop in milk production, lethargy, inappetence, salivation, depression, nasal discharge, stiffness, dyspnea and ruminal stasis (Walker et al. 2012).
Primarily, pathogenesis of BEF is based on vascular inflammation (Young and Spradbrow, 1980) so this provides the rationale for its treatment through anti-inflammatory drugs. Different NSAIDs have been used in previous studies phenylbutazone, flunixin meglumine and ketoprofen (Uren and Murphy, 1985; St George et al. 1984) but no study has been found using most common field NSAID of Pakistan, meloxicam. So, here a comparative study was carried out between three NSAIDs meloxicam, ketoprofen and phenylbutazone on naturally infected BEF animal.

Publisher: 2015Dissertation note: Poultry industry is the most effective and economical source of animal protein. Because of increasing future demands, poultry industry is unable to narrow down the animal protein supply and demand gap. Poultry producers are looking forward for using the alternate source of chicken meat, which in the future will come from pigeon and quail meat. It will be very help full for increasing gross domestic production (GDP) through livestock sector (Basit et al. 2006).
Pigeons have been domesticated to live close with human beings. Pigeons originate from the rock dove in Europe, have been partially domesticated and carried to all parts of the world. Pigeons have been divided into three groups.
1) Poultry pigeons
2) Carrier and racing pigeons
3) Fancy and feral pigeon
Pigeons are easily bred to produce a variety of plumage or to provide squabs for the table (Basit et al. 2006).
It is very well known that internal parasites cause great loss to the host, by different ways. These parasites live at the expense of host depriving them from the nutrients essential for their growth. Moreover they cause mechanical harm by producing inflammation and tissue damaged. Protozoa inhabiting the digestive tract of birds are responsible for considerable economic losses. Heavy infestation of the parasites affect the health of birds with loss in the body weight, retarded growth, unthriftiness, damage to the gut epithelium, fertility disturbances, emaciation and death especially in young birds (Urquhart, 1996).

Common name of Trichomonas gallinae is canker, frounce and roup. Predilection site of this parasite is esophagus, crop and proventiculus. It belongs to the family Trichomondidae and class Zoomastigophorasida (Taylor et al. 2007).
Body of T. gallinae is elongated, ellipsoidal os pyriform. Its size is 5-19 × 2-9 μm. It has four anterior flagella that arise from blephroplast, having undulating membrane that does not reach the posterior end of body and free posterior flagellum is absent. Its axostyle is narrow and protrudes 2-8 μm from the body and its anterior portion is flattened into a spatulate captulum. Its parabasal body is hook shaped and parabasal filament is present (Taylor et al. 2007).
The host of T. gallinae is pigeon, turkey, chicken and raptors (hawks, falcons and eagle). As the method of reproduction is concerned it reproduced by longitudinal binary fission. There is no sexual stages and cyst are present in its life cycle. Lesion present in the turkey and chicken are most commonly in the area of crop, oesophagus, pharynx and no lesion are found in mouth (Taylor et al. 2007).
Size of trophozoites of T. gallinae is about 7-11 μm. Its shape is varied from oval to pyriform. It has four flagella and a fifth recurrent one, which did not become free at the posterior pole. Size of nucleus is about 2.5–3 μm, oval in shape and situated closely below the basal bodies of the flagella. Its axostyle consisted of a row of microtubules that is running from the region of the apical basal bodies to the posterior end of the cell (Mehlhorn et al. 2009).
Infected pigeons show wild signs of depression, lose weight, stand huddled with ruffled feathers and may fall over when forced to move. There is an accumulation of greenish fluid present in the mouth and crop containing large number of trichomonads in it. Yellow, necrotic lesions are present in the esophagus and crop (Taylor et al. 2007).
Introduction

Trichomonas gallinae is a causative agent of trichomoniais in birds. It affects mostly to the young birds and causes death in them, especially in pigeons within 10 days. This Protozoa is present in the gastrointestinal tract of birds and causes greater financial losses. Clinical sign of diseased birds are dull, depress and having yellow color diarrhea. Morbidity rate of this disease is high in birds. If infected birds are not treated, it causes high mortality in diseased birds, due to this reason this problem become very important. Trichomonas gallinae presents in upper digestive system and respiratory system. So it affects both digestive system and respiratory system. It is mainly found in pigeons, but turkey, chicken, hawks, mourning doves, golden eagles, falcons and bustards may also be infested with this protozoa (Saleem et al. 2008).
Small, whitish to yellowish caseous nodules are found in the esophagus, pharynx and crop. Their size increased and may remain circumscribed and separate, or may become thick, caseous, necrotic mass present in lumen. The circumscribed disk shape lesion are known as yellow buttons. Size of nodule is 1 cm or more and found in liver, lungs and other organs (Taylor et al. 2007).
Infection spread to turkey and chicken by drinking contaminated water. The pigeon and other wild birds are also source of infection, which also use the water source. T. gallinae enters in the water through mouth and not from feces of the wild birds. Source of infection is direct contamination because this organism is very sensitive to drying and no cyst are found (Taylor et al. 2007).
There are more chances of trichomoniasis in young one than in adult pigeons. During feeding carrier pigeons transmit this disease to their young ones. The pathological lesions associated with trichomoniasis is inflammation, ulceration, and necrosis in nature. These lesion are more predominant in the oral cavity, esophagus, crop and proventiculus (Kennedy et al. 2001).

This disease is present worldwide. A clonal strain of previously described organism has been recently developed as the cause of widespread disease of birds in Europe and causes a grate economic losses (Ganas et al. 2014). In Britain, this infectious disease was first described in 2005. This disease causes significant mortality in birds which results in decreased population of green finches and passenines (Robinson et al. 2010).
T. gallinae affects upper digestive system of birds and results in pathological changes in structure of different parts of digestive system. It causes slight inflammation of mucosa to large caseous lesions of esophages. These lesion sometime block the lumen of esophagus. Due to this secondary infection of parasites, bacteria and virus takes place in diseased birds. Different strains of parasites move toward other organs such as liver, air sacs, lung, and brain. They causes necrosis of these organ, which leads to the death of birds (De Carli et al. 2002).
Prevalence of T. gallinae infection is different in different age of birds. Prevalence increased with the age of nestling (Krone et al. 2005). A higher prevalence of Trichomoniasis has been recorded in pigeons in Pakistan season wise prevalence has been recorded to be 43%, being non significantly higher in April (56%) than in March (30%). Trichomoniasis positive cases show a significant decrease in hemoglobin concentration, number of monocyte, packed cell volume, body weight than healthy birds (Saleem et al. 2008).
T.gallinae is a parasite of different species of birds ranging columbiformes, diurnal raptors and captive gallinaceous birds. It causes stomatitis, esophagitis and ingluvitis (Bunbury et al. 2007).
This disease is recently emerged in British passerines. This parasite has caused high mortality in finch and their population is decreased and this disease is also spread to continental Europe (Chi JF 2013).
Introduction

The sequence of T.gallinarum is different from Tetratrichomonas gallinarum that is another trichomonad of birds, but it is genetically similar to Trichomonas Caninistomae that affect dog and cat and causes oral infection. Pigeons are prey of dog, so there is possibility that T. gallinae may have infected (carnivorous) mammals in the past (Gasper et al. 2007).
This disease causes large economic loss of avain livestock and also cause problems for wild species of birds. In UK T. gallinae has caused the death of greenfinches (Lawson et al.2006). Trichomoniasis was first reported in 2005 in Britain. It was discovered in finches. It caused large scale mortality in finches with population decline (Robinson et al. 2010; Lawson et al. 2011). In 2007 this disease is reported in finches in the Canadian Maritime provinces, southern Fennoscandia and northern Germany (Lawson et al. 2011). This disease caused high morbidity and mortality in finch population in Britian. It is estimated that about 1.5 million greenfinches which represent the 35% of national population have been died with this disease (Lawson et al. 2011).
In this disease multiple foci of caseous necrosis is seen in oral, esophagus and crop mucosae. There is heavy infiltration of inflammatory cells especially heterophill in these areas. There is multiple foci of necrotic inflammation is seen on liver. Due to excessive infiltration of heterophils in there is thickening of mucosa of easophagus. Necrotic material is also seen in mucosa and submucosa of easophagus. There is necrosis on the tip of villi of intestine and necrotic materials is seen in the mucosa of intestine (Al Sadi et al. 2011).
Trichomoniasis occurred more frequently in young than adult pigeons. High prevelance of trichomoniasis have seen in male than female pigeons (Al Sadi et al. 2011). Nestling birds are more susceptible to this disease than other birds. In Tucson, Arizon study was conduct and this study show that T. gallinae was present in oral cavity of 85% nestling coopers hawks compared to

only 1% of breeding age hawks. This disease is more prevalent in young pigeons. T. gallinae is sensitive to environmental pH. Trichomonas gallinae develop well when pH is between 6.5 and 7.5 (optimum 7.2), but cannot survive in more acidic pH. In fledgling and breeding Coopers Hawks pH of their oral cavity is acidic, so they are less susceptible to trichomoniasis and this is very important in differential prevelance among age group of birds (Urban et al. 2014).
Trichomonas gallinae changes the blood picture of infected birds. It causes decreased values of Hb, PCV and monocytes in infected pigeons than the healthy pigeons, while TLC, heterophils, lymphocytes and eosinophils are increased in disease pigeons than the healthy pigeons (Seddiek et al. 2014).

Publisher: 2014Dissertation note: Pakistan being an agriculture country has 70% of its population that is totally dependent on agriculture and livestock sector which plays an important role in the economy of the country. Livestock has contribution of about 55.4 percent to the agricultural value added and 11.9 percent to the National GDP. Pakistan has population of about 64.9 millions of goat, 38.3 millions of cattle, 33.7 millions of buffaloes and 28.8 millionsheep population according to the economic survey estimate. Mutton production is about 643 million tons and beef production is about 1,829 tons out of total 3,379 million tons of meat production. Livestock produces approximately 49,512 million tons of milk out of which buffalo produces 62.0% while cattle produces 35% and sheep-goat produces 1.69% (Economic Survey, 2012-2013). Pakistan is the 3rd largest milk producing country in the world (Afzal, 2010).
Diarrhea can be defined as an increased in volume and quantity of fecal excretion. The diarrhea may contain mucous, blood, poor odor and variation in color then the normal feces.On the basis of time period, diarrhea has different types likeacute, constant and chronic. Time Period of acute diarrhea is not more than 14 days while in case of persistent/constant form, it continued for more than 14 days and in chronic case the diarrhea remain for a time period of 28 days(Bazeley, 2003)
Diarrhea is a leading factor towards the death of calves. Neonatal calf diarrhea is among the very important diseases of the calves worldwide. It is animportant contribution to the major economic losses in cattle industry. The cause of calve diarrhea may be infectious or non-infectious (Elhassan et al. 2011).
Bad hygiene, overpopulation, overfeeding, hot/cold temperature, feeding the calves artificially and the colostrum’s deprivation are all predisposing factor in the complex etiology of the disease (Hemashenpagam et al. 2009).
Infectious agent and the co-infection of different multiple pathogens are common in calves having diarrhea. Rotavirus, Cryptosporidium, corona virus and enterotoxigenicE. coli collectively are associated with 75-95% of the infections in calf diarrhea around the world. Clinically, Neonatal calf diarrhea is characterized by profuse acute watery diarrhea, progressive dehydration, acidosis and death within a few days. The degree of dehydration is estimated by the physical examination of calf and has been introduced as a reliable method (Radostits et al. 2009).
Experimentally the intestinal potassium and sodium combination can be bothered by different causes and various types of factors. However, electrolytes that are built up in the gastrointestinal tract have a function to reduce the water assimilation. Due to this, the organism losses water and the electrolyte commonly (Smith, 2009)
To evaluate the serum electrolytes as well as the acid-base imbalance, there is a need of laboratory tests which cannot be measured regularly in field condition.To check the degree of dehydration is a uniform protocol and is anticipated by body condition score of calves (Naylor 1989).
The electrolytes deficiency in neonatal diarrheic calves might be the cause of death in some cases. Althoughit is understood that serum concentrations of potassium (K) and sodium (Na) are very much necessary with reference to the fluids composition used for treatment purpose (Rucker et al. 2008).
Trace elements have also important part inthe reproduction, growth and productivity of the householdanimals. The imbalance and Difference in ratio of minerals leads towards both production and economic losses throughout the world. The important symptoms of trace element deficiencies that can be clinically shown in animals are anemia, diarrhea, loss of hair, pigmentation loss, growth disorders in bones, difficulty during walking, a flaky deposit in skin, bending, hyperkeratosis, Para keratosis, lack of appetite, decrease in reproductivity and fertility, young animal growth disorders, Tetany, reduction in protein synthesis, immunity compromised calves, abortion related to non-infectious factors and pica. However, reduction in the concentration of trace elements like cobalt, copper, iron, iodine, manganese, selenium or zinc leads to lower reproduction rates and lactation. Untreated changes in the serum concentrations of Ca, Mg and some trace elements may be the root of cause of some death or post diarrhea complications such growth retardation (Tajik and Nazifi, 2012).
The serum values of calcium (Ca) and magnesium (Mg) that is abnormal persists for a significantly long duration after the treatment of neonatal diarrheic calves. The normal serum concentration of Ca in cow has been reported as 2.43-3.1 mmol/L while the mean serum Ca in diarrheic calves reported was 1.297mmol/L. The normal serum concentration of Mg in cow has been reported as 0.74-0.95 mmol/L while the mean serum Mg was reported to be 0.8145mmol/L (Kaneko et al. 2008).
There are many advantages of using the hypertonic saline solution (7.5% NaCl; 4ml/kg BW) in diarrheic buffaloes and cattle to resuscitate them. Infusion of Hypertonic saline solution resulted in significant increase in sodium and chloride level in serum. The important feature for the successful and complete resuscitation of hypovolemia along with endotoxaemia in diarrheic buffalo calves is the total amount of sodium. The infusion of Hypertonic saline solution is quite safer and it does cause hypernatremia but not for a prolonged period. So, hypertonic saline solution has advantage of resuscitating the calves from acidemia and hypovolemia. It was also helpful in the improvement of oxygenation and cardiovascular performance (Zafar et al. 2012).
The neonatal calf diarrhea can be cured by using the electrolyte therapy like ringer lactate, non-steroidal anti-inflammatory medicines and antibiotics in case of infectious diarrhea and through better farm management depending upon the root of cause (Radostits et al. 2009). There is a hypothesis that treatment of diarrheic calves with NSAIDs attenuates the behavior of sickness as well as gastrointestinal discomfort and encourages the calves to maintain an appetite supports the calves for better performance (Ghanem et al. 2012)

Epidemiological Studies And Chemotherapy Of Postparturient Haemoglobinuria In Buffaloes
by Muhammad Ijaz Ul Haq (2008-VA-83) | Dr. Jawaria Ali Khan | Dr. Muhammad Avais | Prof. Dr. Mian Abdul Sattar.

Publisher: 2015Dissertation note: The district Gujranwala lies at northern part of the Punjab in Pakistan. It is situated between two main cities, in North is Gujrat and in South, there are Sheikhupura and Lahore. The majority of the population lives in the rural areas and mainly earns their livelihood through agriculture. The source of irrigation is perennial and non-perennial canals supplemented by tube wells. This area is heavily populated with buffaloes rather than cattle. Buffalo is playing a foremost role in the national economy by producing milk, meat and draught power. Out of total milk produced in the country, buffalo contributes about 68 %. Due to high fat contents of buffalo milk, it is the ideal species in Pakistan (Bilal et al. 2006). Buffaloes suffer from many fatal diseases throughout the year causing irretrievable economic losses in the GDP. Among these fatal diseases, Postparturient haemoglobinuria is a frightening problem for the economy of Pakistan and as well as for the whole world.
Postparturient haemoglobinuria is a periodic condition seen worldwide that most frequently affects high-yielding dairy animals at the onset of lactation. It is characterized by development of per acute intravascular hemolysis and anemia with potentially lethal results. Beef and non-lactating cattle are hardly ever affected. The exact cause is unidentified, but phosphorus reduction or hypophosphatemia is known to be a major predisposing factor. Decrease in the Phosphorus level of RBCs is known to raise osmotic tenderness of the RBCs, probably predisposing to intravascular hemolysis. A parallel condition reported in New Zealand was linked with copper depletion, potentially building
RBCs were more prone to oxidative trauma. Other potential causes were hemolytic or oxidative plant toxins (Michael A. Moses and Aiello 2014).
In buffalo rearing countries mainly in India, Pakistan and Egypt, Postparturient haemoglobinuria was a major problem as described by (Pirzada and Hussain 1998). Acute hypo phosphataemia was linked with high producing buffaloes and characterized by intravascular hemolysis (Kurundkar et al. 1981).
Postparturient haemoglobinuria was a disease of high yielding buffaloes in district Attock, Rawalpindi, Jhelum and Faisalabad where soil was deficient in mineral contents. The disease was distinguished by icteric and inflexible constipation in pregnant animal (Hussain et al. 1991). Postparturient haemoglobinuria was mainly disease of buffaloes and found in almost all the districts of Pakistan (Pirzada and Hussain 1998).
In buffaloes, Postparturient haemoglobinuria occurred mostly after 3rd week of parturition during 3rd to 5th lactation having a period of 5 to 6 days of illness (Nagpal et al. 1968). The occurrence of hypophosphatemia was highest in buffaloes in progressive pregnancy or in 3rd to 6th lactation (Gautam et al. 1972).
Multiparous females were mostly affected by Hypo phosphataemia and a range of etiological factors were reported to be related with the disease in unusual parts of the world (Singari et al. 1991). Dietary phosphorus shortage and rations containing cruciferous plants were supposed causes of rigorous hypo phosphataemia and had been associated with hemolytic anemia in cows and buffaloes (Heuer and Bode 1998).
Mucous membranes turned pale or might become icteric with the development of anemia and breathing became rapid and shallow with tachycardia (Spears 2003). During third to sixth lactation of adult dairy buffaloes, this disease was more frequently seen, showing weakness and recumbency (Macwilliams et al. 1982). The occurrence of the disease in the total cattle population was very stumpy with a case fatality rate ranging from 10% to 50% (Madsen and Nielsen 1939). Sporadically, farms with a predominantly elevated incidence might be encountered but typically only one or two cases were clinically evident at one time (Freudenberg 1955). In Australia, about 70% cases were reported within 30 days of calving (Mulijns and Ramsay 1959). Bulls, ante partum cows, heifers less than two years old and beef cows were rarely affected. A disease called as "red water" in Ontario, was allied with numerous predisposing factors which integrated recent parturition, intense milk production, dietetic phosphorus absence, utilization of turnips, rape, kale, green alfalfa and sugar beet pulp (Macwilliams et al. 1982).
Postparturient haemoglobinuria was one of the foremost and economically important diseases of dairy animals in Pakistan, India and elsewhere in the world (Macwilliams et al. 1982; Chugh et al. 1996; Pirzada and Hussain 1998). Diagnosis was done on the basis of clinical signs, urinalysis and hematological reports of the examined animals (Madsen and Nielsen 1939).
In a survey conducted during 1996 in Punjab (Pakistan), mortality rate due to Postparturient haemoglobinuria in buffaloes and cattle was 5% which translated into estimated annual losses of Rs. 490.2 and 153.1 million, respectively (Farooq et al. 2007).

Publisher: 2015Dissertation note: Cryptosporidium parvum is an emerging waterborne zoonotic disease prevalent
throughout the world. There are different strains of cryptosporidium but most important is
C.parvum.It is intestinal protozoon belongs to coccidian family that causes damage to intestinal
epithelium that leads to villous atrophy so decrease absorption sites from intestine. It is not host
specific it can equally infect humans, calves and foals. It is cross transmissible among mammals.
In horses, cryptosporidiosis is most commonly seen in foals (most frequently 1–4 weeks of age)
and is associated with diarrhea and weight loss. Immuno-compromised foals (including foals
with severe combined immunodeficiency syndrome) are particularly at risk. The present study
was conducted in different studs farms in and around Lahore keeping in view the importance of
C.parvum in foals because it is gaining attention as a most important cause of diarrhea in foals so
that effective therapeutic measures should be adopted to control infection. There are 323 samples
are collected among different stud farms and veterinary hospitals and analyzed by using fecal
floatation method and modified Ziehl-neelsen technique. Infection rate of C. parvum in foals in
this study recorded was (12.30%) from different stud farms and veterinary hospitals. Infection
rate (27%) is higher in foals of age group range between 1day to 3 months while the least
infection rate (2.46%) was observed in 9-12 months age group. Infection rate is reciprocal to age
as the age increase infection rate decrease. Infection rate is independent of sex. There is no
relationship between sex and infection rate. Diarrhea is an important risk factor related to
infection rate. In diarrheic foals infection rate is (22.5%) while in case of non-diarrheic foal’s
infection rate is (6.5%) which showed that infection rate in diarrheic foals is three time more as
Summary
36
Compared to non-diarrheic foals. A significantly higher infection rate was observed in those
foals having contact with other animals like rodents, ruminants and dogs. Infection rate (15%)
was observed in those foals having contact with other animals and infection rate (6.5%) observed
in foals having no contact with other animals. Purpose seems to very important in this study.
Game horses have more infection rate which was (15.45%) as compared to draught horses
(4.4%). Game horses have three times more infection as compared to draught horses because
game horses remain in close confinement and foals have more prone to infection. Management is
an important factor infection rate was more in those stud farms having poor management as
compared to those have good management. Infection rate is poorly manage farms was (20.97%)
and (5.5%) in properly manage farms. The results of the comparative efficacy of nitazoxanide,
furazolidone and garlic showed that the Nitazoxanide was the most effective of the three in
treating cryptosporidium infection under field conditions. Efficacy of Nitazoxanide in treating
C.parvum in foals was (88%) during the study followed by furazolidone which have comparative
efficacy of (77%) than garlic with the efficacy of (70%).
In conclusion from above discussion reveals that C. parvum is prevalent in stud
farms in and around Lahore. Associated risk for C. parvum in foals are age less than 6 months,
immune-deficiency, contact with other animals like ruminants and poor management. Infection
rate is more in game horses as compared to draught horses because game horses are manage in
close confinement so the chances of infection are more. Treatment of C.parvum has long course
and effective drug for the treatment of cryptosporidiosis in foals is Nitaoxanide than
furazolidone. Availability: Items available for loan: UVAS Library [Call number: 2300-T] (1).

Publisher: 2015Dissertation note: Strangles is characterized by upper respiratory tract infection, dysponea, anorexia, regional suppurative lymphadenitis causing high morbidity and low mortality in horses as well as in mules and it is an infectious problem of equine. Considering the significance and utilization of equines in our country and the substantial losses rendered by Strangles, the present project was designed to study epidemiology, diagnosis and chemotherapy of strangles in Lahore, Okara and Sargodha districts of the Punjab province in Pakistan. Streptococcus equi subspecies equi is highly prevalent in animals recently recovered from strangles and antibiotics along with immune stimulants and non steroidal anti-inflammatory drug became helpful in the elimination of carrier status of animals for S. equi. Samples were collected from animals recently recovered from Strangles. Samples were collected with the help of sterile cotton swabs dipped in normal saline from nasopharynx & oropharynx followed by culturing of samples on blood agar plates which were incubated anaerobically for a time period of 24-48 hours respectively and S. equi were isolated on the basis of colonies characteristics and growth pattern. Streptococcus equi was confirmed with the help of Gram staining and biochemical tests Catalase reaction, Methylene blue reduction test and Sugar fermentation test. In vitro antibiotic sensitivity test were also performed to select three antibiotics showing best efficacy against S. equi. Carrier animals were subjected to treatment with the help of antibiotic along with combination of immune stimulants and non steroidal anti-inflammatory drug. Carrier status was considered eliminated with disappearance of S. equi from nasopharynx. Blood samples were collected from carrier as well as from healthy animals to check out hematological parameters such as TLC (total leukocytes count), TEC (total erythrocytes count) and MHC (mean hemoglobin concentration) etc. Out of

To study the effect of gastrointestinal helminths on various blood parameters of camels, blood samples were collected from 5 infected and 5 healthy camels. Samples were analyzed using Hematology Analyzer and results were compared.
For therapeutic trials, a total of 30 camels positive for helminths was taken and divided into three groups A-C each group comprising of 10 animals. A fourth group D was selected comprising of 10 uninfected camels. The camels of group A were treated with dry Neem (Azadirachta indica) leaf powder at a daily oral dose of 100 gm/camel for five days, group B was treated with Albenzole granules® (Albendazole) at a dose rate of 15mg/kg bd. wt. PO once. Group C (untreated) was designated as positive control, and the camels in Group D as negative control. Efficacy was determined on the reduction of eggs in feces at day 3, 7 and 14 (post-treatment). In the current study Neem leaves and Albendazole gave following results in the camels affected with Helminths. Neem leaves cured 20% of the animals on day 3rd after the drug administration while 40% and 60% of the animals cured on the day 7th and 14th respectively. Albendazole also gave good results against helminths affected camels. On the day 3rd of the treatment 30% animals cured while 60% animals were cured on the 7th day and on 14th day 80% animals recovered.
Data regarding prevalence was measured by non-parametric, chi-square (χ2), while therapeutic trails were analyzed by repeated measures one way ANOVA, using SPSS (Statistical package for social sciences), P < 0.05 was considered significant.

Publisher: 2015Dissertation note: Dogs are one of the most commonly owned companion pets worldwide. They are kept for various factors such as hunting, guarding, and amusement or for animal assisted therapy. Tick infestation is a common problem in dogs and its transmitted infections usually tick borne hemoparasitic diseases are emerging as a worldwide problem not just for animals but also for humans. Due to this phenomenon, ticks are now recognized as a major cause of various diseases in of urban environments. The current research has been conducted to study the prevalence of tick infestation, associated risk factors and chemotherapeutic trials of topical acaricides were used in order to study comparative efficacy, were conducted in dogs. Furthermore, prevalence of tick borne hemoparasitic diseases was also observed by performing microscopic blood smear examination in dogs of Lahore district.
A total of 300 dogs (n= 200 positive for tick infestation; n= 100 negative for tick infestation) having tick infestation were included in the present study. Dogs of different sex, age and breed were selected for tick collection. The ticks were collected with the help of forceps from the target sites of each dog, while adopting all necessary measures to avoid damage to the mouth parts of the ticks and skin of the host. The collected ticks were preserved in plastic containers containing 70% ethanol, which was separate for each specimen. Ticks were identified under stereoscope by observing morphological characteristics of each tick, according to the key. Blood sample for tick borne hemoparasitic diseases was drawn from cephalic vein of each dog using disposable syringe and was poured into EDTA vacutainer. Thin blood smear slide was then prepared from the blood of the animal, dried in air and was stained using Geimsa’s staining method. The hemoparasites observed in the blood of the dogs were then characterized and

identified by their morphological characteristics. For chemotherapy, a total of 30 tick infested dogs of different breeds viz. Rottweiler, German shepherd and Labrador was used in therapeutic trials. Each breed of dog was divided into 2 subgroups which were then treated with topical ivermectin and fipronil 1500μg/kg b.w and 15mg/kg b.w respectively. Efficacy of the drugs was then measured on the basis of disappearance of clinical signs and reversal of tick infestation at day 2, 4 and 6 of post-medication. Data regarding the prevalence of tick borne hemoparasitic diseases and tick infestation was analyzed by using Non-parametric, Chi-square test whereas data on therapeutic trials was analyzed by Z-test, using statistical package for social science (SPSS). P < 0.05 was considered significant.
The results obtained showed us that the study area is at a risk of tick infestation and tick borne hemoparasitic diseases. In dogs, Rhipicephalus sanguineus (brown dog tick) species was observed and identified as a major tick infesting dogs of the study area during the course of study. Various determinants including tick density and its genus, host age, sex, predilection site host breed and season significantly affected the tick infestation in the study area. The prevalence for tick infestation was found highest in Pastoral dogs as compared to other breed types found in dogs. Among breeds German shepherd showed highest prevalence for tick infestation. Adolescence age group among dogs was more prone to tick infestation. The number of males affected by ticks was highest as compared to females in dog population. Among the dog population, majority of the animals infested by ticks were categorized under mild infestation. The most favorable predilection site for tick infestation in dogs was ear pinnae, followed by head and then neck. Monsoon was the most favorable season for tick infestation in dogs. September was found to be highest favorable month for tick infestation in dogs.
Summary
52
In tick borne hemoparasitic diseases, babesiosis was the highest prevalent disease in dogs (63.33%), followed by trypanosomiasis (0.66%) and mixed infection (0.33%). Age group among dogs showed non-significant factor affecting prevalence for TBHD’s. The number of affected dogs for babesiosis was greater in adolescence age group as compared to other age groups. On the other hand, trypanosomiasis and mixed infection adult age group was found highly susceptible. Males of canine group were slightly more susceptible than females in case of babesiosis. Similarly for trypanosoniasis and mixed infection males were more prone than females. For babesiosis, monsoon was the most favorable season in dogs. Whereas for trypanosomiasis and mixed infection, post monsoon was found to be favorable season in dogs. In breed type of dogs, prevalence for babesiosis was found highest in Pastoral dogs. In dogs the prevalence for babesiosis was found highest in German shepherd breed, whereas for trypanosomiasis and mixed infection Cross breed was the most susceptible breed. For trypanosomiasis and mixed infection Cross breed was the most susceptible breed type. The prevalence for babesiosis was found highest in the month of September. For trypanosomiasis and mixed infection, the month of October was found to be highest susceptible month for dogs.
Chemotherapeutic trial of topical acaricides against tick infestation in dogs revealed that Fipronil was more efficacious drug as compared to Ivermectin.
Such type of epidemiological data of tick infestation, TBHDs and its chemotherapeutic trial will help to control tick infestation and tick borne hemoparasitic diseases to save the life of companion animal. Availability: Items available for loan: UVAS Library [Call number: 2303-T] (1).
