Publisher: 2011Dissertation note: This project was designed to evaluate the comparative efficacy of two different techniques of Ureteroneocystostomy for ureteral reimplantation in dogs. Sixteen stray dogs were selected and were divided into two groups i.e. group A & B, comprising eight animals each. The efficacy of the procedures was evaluated on the basis of physical examination, serum evaluation for creatinine & urea, contrast radiography and post mortem findings.
The surgery was conducted through ventral midline celiotomy from umbilicus to a variable distance caudally under general anesthesia in both the groups and urinary bladder was exteriorized in both the groups. In group A, longitudinal incision was made near the bladder dome, a mosquito hemostat was passed from the surface of the bladder through the bladder wall at an oblique angle then the ureter was brought to the level of the bladder mucosa incision. A 6-0 Polyglactin 910 (Vicyrl,Jhonsons & Jhonsons Pharma) suture with double needles was then placed at each apex of the spatulated ureter and the full-thickness of ureter anastomosed to the bladder mucosa in one layer with a continuous, nonlocking stitch. In group B, two small incisions were made at the outer part of the bladder wall until the mucosa was seen through the cuts. Then a submucosal tunnel was dissected between them and the graft's ureter was introduced. Once the ureteral end has been spatulated, a reabsorbable 4-0 suture thread with independent needles at each end was passed (each needle goes from the outer to the inner side of the ureteral wall. Afterward, both needles were advanced into the bladder by the creation of a mucosal incision at the distal hole; these two needles then transfixed the bladder wall
from inside about 2 cm distally. During knotting of the suture (outside the bladder) the distal ureter was pushed to the bladder wall that it anchored against the mucosa.
The results of this study clearly indicated that both techniques are equally effective for the reimplantation of the ureter to bladder but an extravesical ureteroneocystostomy (Modified Lich Gregoir) has an edge over in intravesical mucosal apposition technique (Modified Lead better-Politano) in terms of effectiveness , safety and minimum postoperative complications.

Publisher: 2011Dissertation note: Study was carried out in district Rajanpur from February, 2011 to April, 2011 to find out percentage of infestation and to study chemotherapeutic trails against warble fly infestation in cattle in three tehsils namely Rojhan, Rajanpur and Jampur of district Rajanpur. In each tehsil 200 cattle were examined to record clinical signs of hypodermosis. For treatment of affected animals drug trail were done with Trichlorophon (Tagafon Star,Pakistan) and Ivermectin (Imec, SJG, Pakistan) 1% subcutaneously @ 0.2mg/kg body weight. Study included percentage of infestation in cattle in the households, veterinary hospitals and private farms. Average percentage of warbles in cattle was calculated and found 10 %, 17% and 16.5% in Rojhan, Rajanpur and Jampur respectively. It was found that percentage of infestation was 12% to 18% in hilly areas as compared to semi-hilly areas with 8% to16% and riverine areas 8% to 18% warble fly infestation in cattle. It was observed that warble fly infestation in cattle was absent in some plane areas in tehsil Jampur.
The comparison of different chemotherapeutic trails against Hypodermosis in cattle were observed and recorded. Three groups of cattle were made for chemotherapeutic trails against hypodermosis. Application of Tagafon in two different groups of cattle was carried out to evaluate their efficacy against Hypodemosis. In one group Trichlorophon (Tagafon Star,Pakistan) was applied with cotton gauzes by swabbing and spraying method with 5% solution of trichlorophon. In second group Trichlorophon (Tagafon Star, Pakistan) was given by drenching method with 2% solution at a dose rate of 0.2ml/kg body weight. In third group (Inj.Imec, SJG, Pakistan) Ivermectin 1% at dose rate of 0.2mg/kg body weight subcutaneous injection was carried out. Ivermectin1% was found to be 100% effective. Tagafon (Trichlorophon) was found 90% effective by swabbing and spraying method with 5% solution and Tagafon (Trichlorophon) by drenching method with 2% solution was found 85%effective against warble fly infestation in cattle in the study area. The data was analyzed statistically and found significant.

; Nature of contents: ; Literary form: Publisher: 2011Dissertation note: Donkeys act as draught animals and are used for a variety of purposes. Donkeys are still the "beasts of burden". Helminthes parasites, particularly strongyle nematodes, are the common inhabitants of the gastro-intestinal tracts of equines. Strongylosis is one of the most important parasitic diseases of equines. Diarrhea, anorexia, weight loss and moderate anaemia are the clinical signs in infected animal resulting in heavy mortality. The present project was therefore designed to investigate the infection rate of nematodes in donkeys, to calculate the efficacy of Ivermectin and Neem against strongylosis and to study the effect of strongylosis on various blood parameters (DLC and Hb).
Three hundred donkeys (n=300) were examined coprologically for the presence of nematodes. 167 donkeys were found infected with various parasites with the overall infection rate being 55.66%. Out of 167, 85 donkeys were infected with strongylus, 29 with trichostrongylus, 19 with trichonema, 19 with gastrodiscuss and 15 with mixed infection. So the infection rate for strongylus, trichostrongylus, trichonema, gastrodiscuss and mixed infection was 28.33%, 9.66%, 6.33%, 6.33% and 5% respectively. For drug trails thirty donkeys naturally infected with strongylosis were selected. These animals were divided into three groups A, B and C, comprising of 10 animals each. Another group D comprising of 10 healthy animals was also made. Group A was treated with ivermectin at the dose rate of 0.2 mg/kg body weight (1 ml/50 kg b w) once. Group B was treated with neem dry leaves at the dose rate of 375 mg/kg body weight mixed with wheat bran for four days. Group C was kept as positive control (Infected-Untreated) and Group D was kept as negative control (Uninfected-Untreated).
The faecal samples were collected on day zero pre-medication and on day 7 and 14 post-medication. The efficacies of ivermectin and neem were calculated on the basis of reduction in number of eggs per gram (EPG) of the faeces. The efficacy of ivermectin was 73.21 and 96.42% on day 7 and 14 respectively. The efficacy of neem was noted to be 22.22 and 33.33% on day 7 and 14 post-medication respectively. It was concluded that ivermectin was most effective. The blood samples were also collected on day zero (pre-medication) and on day 7 and 14 (post-medication) and were examined for hematology. Groups A, B and C had low haemoglobin values. The values get improved in groups A and B after treatments but the value further decreased in group C because this group was kept as infected control. The Hb value remained normal in group D as the animals in this group were healthy. In group C there was significant increase in eosinophils.

Publisher: 2011Dissertation note: The present project had been designed to study the effect of heat stress on cattle calves and to evaluate the efficacy of electrolytes solution (Normal Saline and Ringer Lactate) on various blood parameters. Five groups of calves comprising 10 in each group were selected for experimental study. Group A: Affected calves with heat stress were provided shade after taking TPR and the effect of shade were checked after one hour. Group B: Heat stressed calves of same age group were given Normal Saline IV according to their body weight and the effect were checked through TPR, hematology and blood electrolyte. Group C: Heat stressed calves of same age group were given Ringer's Lactate IV according to their body weight and the effect were checked through TPR, hematology and blood electrolyte. Group D: calves of same age group affected with heat stress were taken as the positive control. Group E: calves of same age group were normal healthy calves (negative control). Temperature was taken at regular intervals of one hour daily. Respiration was observed by placing the hand in front of nostrils. Heart rate was observed by stethoscope daily in morning and evening. The blood sample of each calf was collected both for control and experimental animals through disposable syringe from jugular vein. The blood was shifted to University Diagnostic laboratory, University of Veterinary and Animal Sciences Lahore. The samples were taken before and after therapeutic trials. Blood samples were taken for blood electrolyte examination and hematology. Serum of the blood was separated by centrifugation for electrolytes measurements. The flame photometer was utilized to measure the serum sodium (Na+) potassium (K+) Chloride (Cl+) and Bicarbonate (HCO3) concentration. The physical sign of experimental group before cooling were noted .sever sweating and panting were observed under physical sign. The pulse rate, respiration and rectal temperature of experimental group before cooling were increased. Changes found in CBC and blood electrolytes like sodium, potassium, chloride and bicarbonate were measure by flam photometry.
These all observation showed that the animal of experimental group before cooling were suffering from electrolyte imbalance ,but it was not so serious which may result in death of the animal, however the persistence of that condition might result in heat stroke which is often lethal.
It is concluded that serum electrolyte concentration, CBC and pulse rate, respiration and rectal temperature help in accessing the condition of animal suffering form the heat stress. From the present study it can be concluded that heat stress cause changes in biochemical and Hematological parameters in calves. These changes can be overcome by giving animal's fluid therapy and by providing good shade in hot summer. Further studied are required to Conducted on other species of animals to understand the effect of heat stress .Other biochemical and hematological parameters should be studied in bovine calves and other animals for the better understanding the effects of heat stress.

Publisher: 2011Dissertation note: Some intestinal parasitosis pathogen have potential is well known, many of them not shows symptoms, due to the body immunity and climatic element (Vinayak et al. 1990). While other shows like B. hominis and C. parvum. Persistent and acute diarrhea has been linked with the Giardia duodenalis and Entamoeba histolytica. Entamoeba / dispar, a protozoa having alike character with E. histolytica which is a not involve in causing diseases but proved symbiotic association in gut, not harms the other.
Children up to age of 3 years commonly found with anemia and iron deficiency due to malnutrition caused by high prevalence of parasitosis. (Kapur et al., 2001)
Cryptosporidium parvum within age of 5 years children gave highest prevalence rates in a community, among different parasites (Palmer & Biffin 1990). Cryptosporidium spp have been causative agent of persistent and acute diarrhea in many research works (Lima et al. 1992).
In developing countries intestinal parasitosis infection is a major health issue by promote health standards and controlling the carriers or vector, most countries have successfully reduced the rates of infestation. However, in developing countries geographic, socio-economic factors and natural calamity increase the health problems. Countries, which are geographically located in hot and humid areas along with poverty, unavailability of clean water, malnutrition, and high population density provide maximum chances for the development and high intestinal parasitic risk. Because of lack of sufficient research and attention of infectious and parasitic diseases in developing countries is the main problem hurdle to eliminating the risk of parasitic infestation.( Sayyari et al.,2005)
Pakistan estimated the intestinal parasitosis as the important public health problem. In developing countries intestinal parasitosis infection is a major health issue by promote health standards and controlling the carriers or vector, most countries have successfully reduced the rates of infestation. However, in developing countries geographic, socio-economic factors and natural calamity increase the health problems. Intestinal parasitosis is most familiar in children due to lack of hygienic condition. Physiologist and medical specialists are recommended that parasitosis infections delay children's growth, malnutrition, lost the opportunities of education and development. The under study carried out to record the prevalence of intestinal parasitosis within children at day care centers of Lahore and also to relate environmental factors with socio-economic status.
The basic purpose for collection of stool specimens were to examined the parasitic eggs, cysts, and larvae, by different methods like fresh smears method and Scotch tape method. Trophozoites of amoeba were examined in fresh smears. Oxyure eggs were seen in Scotch tape slides. The parasitic size was measured by ocular micrometry method. Formaline ether concentrate method was being done for finding cysts (Machado,1999 ; Lotphy 1990). Socio- economic and environmental factors were also is studied.
Of 174 children 56 children studies positive for parasitosis, 96 were males and 78 females. One or more intestinal parasites were identified in 40 (22.9% children) the most pravelent parasite were E. vermicularis 9.19% G. lamblia 6.89% E.histolytica 5.17% A.lumbricoides 2.87% H.nana 1.14% T. saginata1.72% T.trichiura 4.59% and E.coli 0.57% showed a low infection respectively

Publisher: 2011Dissertation note: The present study was designed to determine diagnosis and infection percentage of Bovine anaplasmosis in cattle and buffalo of different age groups in and around District Lahore, and to study the comparative efficacy of diagnostic methods that is Polymerase chain reaction (PCR) and Microscopic Examination. For this purpose 160 blood samples were collected from cattle and buffaloes ,randomly from eight villages , during the month of May, June, July, August of 2010 in and around District Lahore.80 samples were collected from cattle and 80 were collected from buffaloes and these samples were further categorized into two age groups that is 40 samples were collected from calves of 1 month to 6 month of age and 40 samples were collected from calves of 7 month to 12 month of age of each species. Screening was done by blood smears, stained by Giemsa'wright staining technique and later the blood samples from the same animals were also processed by PCR.
The blood smears showed Anaplasma marginale as dense , round, deeply stained body, approximately 0.3-1.0um in diameter. Most of them were located on or near the margin of the erythrocyte.On the basis of Microscopic examination overall 11.25% (18\160) prevalence was recorded. On the basis of polymerase chain reaction (PCR) prevalence of Anaplasma marginale 25.6%(41\160) was recorded, showing the presence of carrier animals in District Lahore. The blood smears showed maximum prevelance in cattle of age 7 months to 12 months of age that is 20% (8\40) than animals of age 1 month to 6 month of age 10% (4\40).The blood smears showed maximum prevelance in buffalo calves of age 7 months to 12 months of age that is 10% (4\40) than animals of age 1 month to 6 month of age 5% (2\40). The blood smears showed that the prevelance of Bovine anaplasmosis is more in cattle 15% (12\80) than buffalo 7.5% (6\80). The overall prevalence 25.6% (41\160) was recorded for Bovine anaplasmosis , during summer season on the basis of PCR. The Polymerase chain reaction showed maximum prevelance in cattle of age 7 months to 12 months of age that is45 % (18\40) than animals of age 1 month to 6 month of age 20% (8\40). The Polymerase chain reaction showed maximum prevelance in buffalo animals of age 7 months to 12 months of age that is 27.5% (11\40) than animals of age 1 month to 6 month of age 10% (4\40). The Polymerase chain reaction showed that the prevelance of Bovine anaplasmosis is more in cattle 32.5% (26\80) than buffalo18.75 % (15\80).The results have shown high efficacy of PCR as compare to Microscopic Examination.
It is anticipated that present study was proved helpful in diagnosis of Anaplasma in infected as well as in carrier animals in District Lahore , and will be beneficial for further study.

Publisher: 2012Dissertation note: The background of the hematological studies of reptiles has assumed greater significance due to an increased trend of keeping them as pets and to identify any pathological condition in them in wild for their conservation. The objectives of study is to identify the hematological parameters of Indian Rock Python (Python molorus molorus) in Punjab, Pakistan. This is the only species of python found in Pakistan and a Near Threatened species according to IUCN Red Data Book. There is no data available on the blood chemistry of this species in Pakistan . These values will act as reference values for future studies in Pakistan.
The hypothesis of the present study is that the hematology of Indian Rock Python could vary from that of Burmese Python and thier is a relatively high difference in the values of heterophyls,Basophils Eosinophils and monocytes so hypothesis proved.
The parameters like red blood cells count, total leukocyte and thrombocyte counts, packed cell volume, hemoglobin evaluation and differential leukocyte count were studied by collecting the 3 ml blood from the caudal vein of pythons by 23 Gauge syringe and we compare the results with published record of Burmese Python other than this captive and wild pythons hematology is also compared. Mostly standard procedures for counting these values were be followed. Results showed that the Packed cell volume for all the five samples is 3.9 ± 4 SD, Hemoglobin is 7.18 ± 0.61 SD and the Red blood cells count mean is1.23 × 106 /µl with SD of 0.32. White Blood cell count is15.46 × 103 /µl with SD of 1.97,Heterophils6.66 × 103 /µl with SD of 4.16,Lymphocytes4.98 × 103 /µl with 2.47 SD,Monocytes0.22 × 103/µl with standard deviation of 0.13,Azurophils(× 103 /µl) are 0.904+0.55, Eosinophils(× 103 /µl)0.836+0.61, Basophils(× 103 /µl)1.38+ 1.77
This present study will provide important information about hematological parameters of Indian Rock Pythons that could be a ready reference for the wildlife veterinarians, conservationists and biologists in future for the conservation and treatment of this near threatened species.

Publisher: 2012Dissertation note: Goat rearing is a traditional activity in peri-urban areas and villages and plays an important role in the nutrition, social and economic needs of the population. Gastrointestinal nematodes are common in various production systems and these infections are the single most significant constraint to small ruminant productivity.
The present study was carried out at Saidu Sharif, District Swat to generate data about the gastrointestinal (GIT) nematodes prevalent in the area. To record the prevalence of various nematodes of goats, a total of 150 faecal samples were examined. A total of 61/150 (40.67 %) of samples were found positive. Different species were identified and included Nematodirus spathiger (28.66 %), Haemonchus contortus (14.66 %), Trichostrongylus spp (4 %), Strongyloides papillosus (6 %) and Trichuris ovis (11.33 %). Highest prevalence of GIT nematodes were found in young and immature animals (48 %) with mean EPG 282 and 211 respectively. Adult had lower infection rate (26 %) with mean EPG of 142. Sex related prevalence indicated that male had higher prevalence (46.66 %) than female (34.66 %) and greater intensity of infection in males as compare to females. Higher infection rate with GIT nematodes was recorded in pregnant goat (42 %) as compared to non pregnant (33.92 %). House hold animals showed high infection rate i.e. 45.33 % with mean EPG of 254 as compared to commercially raised animals which had infection rate 36 % with mean EPG of 169. The Study

Publisher: 2012Dissertation note: The study was conducted in District Swat, Khyber Pukhtoonkhwa province, to study the percentage of carrier buffaloes of hemorrhagic septicemia in the region and Immune status of buffaloes. Tracheal swabs and blood were collected from 200 buffaloes slaughtered at Saidu Sharif slaughter house. The selected buffaloes were divided into four age groups, the first group had animals of two and less than two years of age, the second had animals with age of three years, the third group, five years and fourth group had animals with age of more than five years. Tracheal swabs were cultured for the isolation of Pasteurella multocida, for identification of carrier animals and blood sample were processed to determine the antibodies titer of buffaloes against Pasteurella multocida.
The results showed that 8 (4%) out of total 200 examined buffaloes were identified as carriers of hemorrhagic septicemia by isolating the Pasteurella multocida from their tracheal swab. Out of 8 carrier buffaloes 4 were from group IV, 3 from Group III and 3 from group II. The percentage of carrier buffaloes in four age groups was 0%, 2%, 6% and 8% in group-I, group-II, group-III and group-IV respectively, showed that percentage of carrier buffaloes were high in group IV while lowest in group I. The Pathogenicity tests of the all 8 isolates showed that they were pathogenic to mice and cause their death within 24 hours of incubation.
Serological study of blood sample for antibodies titer showed that out of 200 buffaloes 156 (78%) showed antibodies titer ?1:16 which were considered immune against hemorrhagic septicemia. Out of 156, 17 were from group-I, 46 from group-II, 46 group-III and 47 from group-IV. Percentage of immune buffaloes in different age groups was 34%, 92%, 92% and 94% in group-I, group-II, group-III and group-IV respectively. The higher number of immune animals i:e 94% were in group-IV and the lowest were in group-I i:e 34%.
Results showed that all the carrier buffaloes had antibodies titer more than 1:16. The antibodies titer of the 4 carrier buffaloes were 64, 2 had 128 while 1, 1 had antibodies titer 16 and 32 respectively.

Publisher: 2012Dissertation note: Pakistan is one of sub-tropical countries and its climatic conditions favor parasitic diseases along with disease vectors including mosquitoes. Mosquitoes of genus Aedes are causing Dengue fever. It has become one of infectious vector born disease of world. Annually it is striking around 100 million people with dengue fever and about 5 Lac people with Dengue Hemorrhagic Fever (DHF), resulting in 5 % deaths per year. Current study was conducted to evaluate efficacies of plant extracts against dengue fever mosquitoes of Aedes genus. Study target was to search some safer alternates than that of chemical pesticides. Also exhibiting characteristics like less toxic to environment, do not induce resistance in mosquitoes, do not harm non-targeted organisms, would not be toxic to human beings and will have biodegradation ability. Study has evaluated indigenous plants extracts as potent larvicidal and adulticidal materials.
Mosquitoes were collected from different areas of Lahore and they were identified upto genus level only Aedes genus was identified upto species level, then Aedes aegypti was reared in laboratory to have F 1 generation, to have mosquitoes and larvae for testing the activity of plant extracts. Plant materials were collected from different areas of Lahore. Methanolic extracts of seeds and leaves of Azadirachta indica and lantana camara respectively, were extracted accordingly. Stock solutions were prepared from these extracts and then out of this serial dilutions were made. Experiment was performed in four groups A, B, C & D for both adults and larvae. Each group was representing total of 25 larvae/adult out of which one was kept untreated
as negative control, one with deltamethrin as positive control while two were provided with test concentrations.
LC50 and LC90 was determined by Probit analysis, using SPSS version 13.0 SPSS inc. 2004. lethal concentrations of A. indica mosquitocidal assay were LC50=30.44 mg/l and LC90=62.36 mg/l after 24 hrs and LC50=-9.87mg/l and LC90=59.102 mg/l after 48 hrs at ?= 0.05. X 2 value was significant for 24 h while for 48 h it was not significant. Maximum mortality observed after 24 and 48 hrs is 99% at 70 ppm. DMR test shows after 24 hrs., all treatment means are significantlt different from each other, from control and from mean of insecticide's mortality, control is significantly lower while insecticide treated group has significantly higher than rest.
after 48 hrs. treatments were significantly different from each other while treatment mortality at 70 PPM is significantly higher than insecticide treated group and rest.
Lethal concentrations for L. camara adulticidal assay were LC50=60.40 mg/l and LC90=113.61 mg/l after 24 hrs and LC50=48.20 mg/l and LC90=79.31 mg/l after 48 hrs at ?= 0.05. X 2 value was not significant at 24 h and is significant at 48 h. DMR test after 24 hrs. treatment, control and insecticide treated were significantly different from each while insecticide treated group has significantly higher than rest. After 48 hrs 4 and 5 treatment groups were found significantly higher than rest
Larvicidal assay of A. indica has shown LC50 =52.36 mg/ l and LC90=105.42 mg/ l after 24 h and LC50 =80.70 mg/l and LC90=145.73 mg/ l after 48 h at ?= 0.05. X2 values for both 24h and 48h were not significant. DMR test after 24 hrs. insecticide treated was significantly lower than all above treatment groups. Treatment group 7 has significantly higher mortality than all other. After 48 hrs. there was not any significant difference.
Lethal concentrations for L. camara LC50 =100.76 mg/100 ml and LC90=198.22 mg/100 ml at24 h and LC50 =61.27 mg/100 ml and LC90= 122.45mg/100 ml after 48 h at ?= 0.05. X2 value for both 24h and 48h was not significant. DMR test after 24 hrs. shows insecticide treated group i.e. 8 is significantly lower than all treatment groups except 1 which is at lowest treatment. After 48 4, 5 and 6 had came to same activity level no significant difference was found and were higher than all others.
Conclusion:
Hence it is concluded that crude plant extracts can act as potential Adulticide / Mosquitocide and Larvicides, though these are required in higher concentrations than that of synthetic insecticides and purified botanical products, but they have advantage of posssessing less resistance presentation and safe for aquatic life. It is also concluded that chemical insecticide used i.e. Deltamethrin has higher efficacy as adulticidal with drastic effects on environment and other beneficial insects. But it was found least effective as larvicidal compared to crude plants extracts. It is suggested that plant extracts can prove a better, safer and cheaper alternate these should consider as a better alternate to control most lethal disease of present time i.e. Dengue fever by eradicating its vector i.e. Aedes aegypti mosquito.

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: Introduction: The current investigation was carried out to study the effect of season on
the morphometric values of corpus luteum and ovary in spring (February-April) and dry
hot (May-June) seasons in the same animals and to characterize the biometry of corpus
luteum and ovary during estrous through ultrasonography in Nili-Ravi buffalo. The
correlation between the plasma Progesterone concentrations and ultrasonographic
biometry of corpus luteum was also studied during estrous in spring and dry hot seasons.
Materials and Methods: The study was conducted on ten female Nili-Ravi buffaloes in
both the seasons (spring versus dry hot). The ultrasonographic measurements and
echogenicity of ovaries and corpus luteum were performed by using linear rectal probe
(Agro-scan AL) of 5.0 MHZ on alternate days during the entire length of estrous cycle.
The plasma progesterone level was determined by taking 10 ml blood samples by
coccygeal vein puncture on the examination day from each animal in test tubes,
containing EDTA. The collected blood was centrifuged at 4000 rpm for about 20 minutes
and then the plasma was harvested, labeled and stored at freezing temperature (-20 °C)
until progesterone (P4) evaluation through ELISA technique.
Statistical Analysis: The data obtained by the ultrasonographic examinations was
analyzed with the help of paired t-test and the correlations regarding plasma progesterone
(P4) concentration and the morphometric values of corpus luteum were determined by
Pearson correlation by using computer software SPSS statistics version 17.

; Nature of contents: ; Literary form: Publisher: 2013Dissertation note: Background
Pakistan is gifted with a large population of small ruminant including 58.3 and 27.4 million heads of goats and sheep respectively 2010.According to Livestock Census 2006, there were about 92164 sheep and 221912 goats' populations in Bannu district. Sheeps and goats are playing a leading role in the national economy by producing wool, skin, meat, milk and farm yard manure. Fasciolosis, parasitic gastrioenteritis, hydatidosis, coccidiosis, ectoparasitism, theleriosis and babesiosis are the major parasitic problems of small ruminants .There was an urgent need to carry out research on applied aspect leading control of parasites.
Study Objectives: The main objectives of the present study were;
(i) To have an overview on the overall prevalence of ectoparasites and endoparasites in small ruminants throughout the district by means of fecal tests.
(ii) To observe the affect of ecto and endoparasites on blood profile of the infected individuals.
Hypothesis: It was hypothesized that
¢ Parasitic diseases are highly prevalent in sheep and goat in District Bannu..
¢ External and internal parasites have significant effect on blood parameters.
Methodology and Results
During this study period 500 sheep and 500 goats were examined for endo and ectoparasites while using various fecal tests such as using direct microscopic examination, simple test tube flotation method and sedimentation method for endoparasites. Out of 500 goats and 500 sheep, 47 goats and 63 sheep were found positive for ectoparasites and percentage ratio was 9.4% in goats and 12.6% in sheep. Mostly, three types of ectoparasites were observed in both of cases i.e. goats and sheep (ticks, lice and mites). The total no. of positive cases found for ectoparasites in goats were 244 (ticks 10.2%, lice 30.4% and mites 8.2% in district Bannu). This result indicates a significant load of ectoparasites in this area of the country. Out of 149 positive cases of ecto-parasites in sheep; tick infection was 7.8% (39/500), lice 15.2% (76/500) and mite infection was 6.8% (34/500). Fecal samples of all 1000 animals were analyzed for the presence of endoparasites, out of which 90.6% goats and 87.4% sheep were found positive for endoparasites. Overall goats were more likely to be positive for Haemonchus Spp. and almost 50.2% (251/500) animals were found positive. The prevalence of other endo-parasites like Trichurus 5.6% (28/500), Strongyloid 4% (20/500), Coccidia 8.6% (43/500), Fasciola 12% (60/500) and Trichostrongyloide were 10.2% (51/500) while in case of sheep Haemonchus Spp. positivity was 33.2% (166/500). The prevalence of other Endo-parasites like Trichurus 6.8% (34/500), Strongyloid 2.4% (12/500), Coccidia 6.8% (34/500), Fasciola 10.6% (53/500) and Trichostrongyloide were 13.6% (68/500). The hematological profile of infected animals indicates high TLC and low hemoglobin level.
Conclusion
It is concluded that high prevalence was due to poor management and lack of knowledge about feeding, vaccination, hygienic conditions and lack of proper deworming programme. To overcome the problem it was necessary to educate the farmers about deworming programme and proper use of insecticides.

Publisher: 2013Dissertation note: The present project was designed to study the presence and importance of
M. pachyderma infection in otitis externa in domestic dogs and to compare the efficacy of clotrimazole and nystatin, in district Lahore, Pakistan as no such previous reference is available. Random samples were collected for a period of three months, from the Government and private pet clinics. The targeted population was pet dogs of different age, sex and breeds. Samples were collected from all the dogs suffering from otitis externa brought to the clinics. The positive animals for M. pachyderma were divided into two groups, i.e. A and B, and treated with clotrimazole and nystatin respectively. A total of 200 cases of otitis externa were recorded and a prevalence of 23% of otitis externa with M. pachyderma infection were found positive.
In the present study, a non-significant difference (P>0.05) was observed between pendulous ear and erected ear dogs and no sex predilection was observed (P>0.05). However, a higher prevelance (86.90%) was recorded in dogs more than one years of age group. In the present investigation, clotrimazole showed higher efficacy (P < 0.05) with the significant reduction of yeast population and clinical signs of otitis.

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.

Publisher: 2013Dissertation note: The KCN intake has been linked to central nervous system (CNS) syndromes and thyroid in animals as well as humans. It is very potent toxin even at very narrow dose ranges. Prolonged KCN exposure has also been associated with reduced growth rate in animals, disturbance in thyroid metabolism, lesions in liver, kidneys, lungs and also CNS pathology.
Male mice weighting about 20-40 grams were purchased from Veterinary Research Institute, Lahore, National Institute of Health, Islamabad, Animal house, University of Veterinary and Animal Sciences, Lahore and divided into 30 treatment groups. After acclimatization of mice, carefully, the mice were grouped as follows:
Control group
A group of 6 mice were treated with potassium cyanide (KCN) intra-peritoneally at 5.5mg/kg that induced a knock down state with recovery period of approximately 1 hour. Prior to each experiment, three or more mice were treated with KCN at this dose to verify that the recovery time was close to 1 hour.

A group of 6 mice in group 27 were treated with ST at 600 mg/kg intraperitoneally (i.p) and any effects on righting reflex recovery time were noted.
Aqueous Garlic Extract (AGE) + Sodium Nitrite (SN) (Group 28)
The mice in group 28 were treated with AGE + SN at 750 mg/kg and 20 mg/kg intraperitoneally (i.p) respectively and righting reflex recovery time was noted.
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.

Publisher: 2013Dissertation note: Toxoplasma gondii is an obligate apicomplexan, intracellular, parasite that infects all warm-blooded vertebrates, including mammals and birds. Human beings can be infected by ingestion of oocysts from cat faeces or through the consumption of meat containing Toxoplasma gondii cysts. Thus, food animals can be the source of transmission of Toxoplasmosis in human population especially among people who consume undercooked meat in the forms of barbecues, beef steaks, kebabs, burgers and shawarmas. Oocysts of T. gondii from cat faeces were identified by using direct microscopy and flotation technique. The positive oocysts were confirmed by micrometry having diameter of 9-13 ìm. The oocysts were then sporulated in aerated condition. After sporulation oocyst were inoculated in Swiss albino mice for in-vivo culturing. After 56-70 days brain tissue was collected from infected mice and subjected to DNA extraction and PCR amplification. Similarly DNA was also extracted from sporulated oocyst for copro-PCR. Out of 200 faecal samples only three were found positive for Toxoplasma gondii through direct microscopic examination and flotation technique. From positive faecal sample and brain tissue DNA was extracted by QIAGEN mini stool kit and QIAGEN DNA mini kit. After DNA extraction the samples were examined through PCR by using specific Toxoplasma gondii B1 gene primer having 529 bp size. Two hundred faecal samples were examined for T. gondii using direct microscopy, flotation technique, bioassay and polymerase chain reaction. Out of 200 samples 3 (1.5%) were found infected through direct microscopy and flotation technique. Toxoplasmosis was more prevalent in adult cats (1.65%) as compared to young ones. Prevalence was also found high in females (2.08%) as compared to males. Similarly healthy cats have higher prevalence rate (1.30%) as compared to diseased ones. A further confirmation was done through polymerase chain reaction and brain tissue cyst Bioassay give 1 positive amplification while Copro-PCR gives 2 positive amplifications. Therefore it can be concluded that the copro-PCR is can be used for the confirmation of Toxoplasma oocysts from cat faeces and tissue cysts from bioassay in mice. Therefore, we propose that the copro-PCR can be used as the new gold standard for determining potential cat infectivity and tissue cysts from bioassayed mice or contaminated meat samples of livestock.

Publisher: 2014Dissertation note: Fascioliasis is a wide spread parasitic disease of ruminants causing great economic losses in terms of decreased milk and meat yield and predisposing to many bacterial infections. Looking the importance and utilization of the small ruminants in our country and the substantial losses because of the Fascioliasis this study was designed to study the prevalence and treatment of Fascioliasis in and around Rawalakot Azad Kashmir.
For this purpose a total of 300 Ovine faecal samples were collected from different areas of Rawalakot. Faeces were collected from sheep of various age, breed and sex. Faeces of each sheep were examined by direct smear, sedimentation and flotation techniques. Positive animals were selected for therapeutic trials.
Out of 300 faecal samples 101 were found positive for Fascioliasis. Overall prevalence was 33.6%. Sex wise prevalence was also studied and it was found that out of 75 male sheep 23 were found positive while out of 225 female 78 was positive for Fascioliasis. Prevalence of Fascioliasis was 30.6% in male and 34.6% in female. The prevalence was also studied age wise and three groups were made. Sheep in first group were less than 1 year of age, out of 25 sheep 4 were found positive and prevalence was 16%. Sheep in second group were between 1-2 years of age, out of 156 sheep 39 of this age group were found positive having a prevalence of 25%. The sheep included in third group were greater than 2 year of age, out of total 119 sheep in this group 58 were found positive for Fascioliasis with prevalence of 48.7%.
For therapeutic trials 80 positive sheep were divided in to 4 groups A, B, C and D. Group A and B were further divided in to three sub groups A1, A2, A3 and B1, B2, B3. 10 animals were placed in each sub group and group C and group D. Animals in groups A and B were treated with herbal extracts. Fumaria parviflora was given to group A animals and Caselpinia crista to group B animals @ 60, 70, 80 mg /kg body weight. Animals in group C were treated with Oxyclozanide @ 10 mg/kg body weight, while animals in group D were kept as infected untreated control. The efficacy of single dose of Oxyclozanide was found 100 percent on 18 day post treatment where as the efficacy of single dose of Fumaria parviflora at 60, 70, and 80 mg/kg body weight was 51.6%, 54.6%, 59.4% on 18th day post treatment, While its efficacy at same dose level after second dose was 79.6%, 82.8%, 86.9% on 21st day post treatment and 83.8% 87.5%, 91.8% respectively on 28th day. The efficacy of single dose of Caselpinia crista at 60, 70, and 80 mg/kg body weight was 31%, 41.42%, 58.7% on 18th day post treatment, while its efficacy at same dose level after second dose was 47.36%, 58.85%, 82.55% on 21st day and 51.3%, 63.2%, 87.3% respectively on 28th day.
At the end of research data on prevalence was analyzed by chi square test P < 0.05 was considered as significant whereas data on therapeutic trials was analyzed by using ANOVA in this case p < 0.01 was considered as significant.
From this study it was concluded that Fascioliasis is significantly prevalent in sheep in and around Rawalakot. While Oxyclozanide is most effective drug against Ovine Fascioliasis. The outcome of this study will help the veterinarians and farmers in the field.

Publisher: 2014Dissertation note: Background:
This project was designed to evaluate the anthelmintic efficacy of Chloroformic extract of Calotropis procera leaves against sheep nematodes. For this purpose hundred sheep positive for nematodal infection in BLPRI Kherimurat were selected after fecal examination.
Methodology:
The hundred animals were divided into 5 groups (Group A, Group B, Group C, Group D and Group E) having 20 animals in each group. Fecal eggs counts (EPG) and biochemical tests like the Alanine aminotransferase (ALT), Aspapartate aminotransferase (AST), Alkaline phosphatase (ALP), Albumin, Bilirubin, Creatinine and Urea were done on the day zero of the treatment. For further study, Group A served as an un-treated control. Group B, Group C and Group D were given the Chloroformic extract of Calotropis procera leaves at the dose rate of 3, 6 and 12mg/kg body weight by oral route respectively. Group E was given the Moxidectin at the dose rate of 0.2mg/kg body weight by subcut route. The biochemical tests on the day 3 showed no change in the normal level of the ALT, AST, ALP, Albumin, Bilirubin, Creatinine and Urea. The fecal EPG of all the groups were done on the day 7th and day 14th post treatment. The efficacy of the Group A and Group B was 0% both on day 7th and day 14th post treatment. The efficacy for the Group C was 19.40% and 42.53 % on the day 7th and day 14th post treatment respectively. The Group D showed the efficacy of 80.215% on day 7th and 91.36% on the day 14th of the treatment. The efficacy for the Group E was 85.97% and 93.29% on the day 7th and 14th respectively.
Statistics:
The data from the fecal eggs count and biochemical tests were analyzed by using the ANOVA and LSD.
Conclusion:
The Chloroformic extract of the Calotropis procera leaves have maximum anthelmintic effect at the dose rate of 12mg/kg body weight having no biochemical changes in the blood.

Levels Of Maternal Antibodies Against Pasteurella Multocida In New Born Buffalo Calves
by Muhammad Bilal | Dr. Aneela Zameer Durrani | Dr. Muhammad | Dr. Muhammad Ijaz.
Material type: ; Format:

Publisher: 2013Dissertation note: Buffalo is called black gold. The buffalo is raised for meat and milk purpose in Pakistan.The buffalo calves are at risk of many infectious diseases. One of the most important diseases is Hemorrhagic septicemia (HS). Hemorrhagic septicemia is caused by Pasturellamultocida important strains in Asia are B:2 and B:2.5. Buffalo calves are more suspected to the Hemorrhagic septicemia than adults one. In Pakistan the high prevalence of 49% is in the rainy season (Farooqet al. 2007)
Clinically the signs of Hemorrhagic septicemia includes profuse salivation,pyrexia, respiratory distress, swelling in throat, discharge through nostrils, protrusion of tongue, edema in the brisket area as well as in forelegs. Hemorrhagic septicemia can be diagnosed on the bases of clinical signs and laboratory conformation by Gram staining and. Serum agglutination test, Counter immune-electrophoresis and ELISA techniques are also used.Enrofloxacine was found to be effective treatment in case Hemorrhagic septicemia. Best protection measure vaccination by alum precipitated vaccine (Boudewijn et al. 2008).
During the present study blood samples were collected from the calves at different intervals of times. Serum was separated from that blood and was analyzed by using Indirect Haemagglutination(IHA) Test to observe the antibodies titer in the blood.The data was analyzed to calculate geometric mean titer (GMT) of the antibodies. Immunity status is much important in the defense of disease especially in the newly born claves which are more at risk of infections.The result of present study showed geometric mean titer 16 in colostrum of vaccinated dams and their newly born claves showed 0, 3. 4, 7 and 3 at 0 hour, 72 hour, 7, 15 and 30 days of their age. Colostrum of non-vaccinated dams showed GMT 8 and their newly born claves showed 0, 1. 3, 3 and 1 at 0 hour, 72 hour, 7, 15 and 30 days of their age.The maternal antibodies which are produce in the body of mother are transferred to their calves.The calves given birth by the vaccinated dams receive much higher level of antibodies from their mother than the calves born from non-vaccinated dams. This antibodies production in non-vaccinated dams is because of the carrier status of hemorrhagic septicemia.The non-vaccinated dams which are not expose to the any type of HS infection or not expose to the vaccines, they do not produce antibodies against Pasturellamultocidaand also not transfer to their young babies after birth.
The present study showed that claves of vaccinated dams are much protected in their early period of life against hemorrhagic septicemia. Buffalo calves need quick and intense care at early age and they need quick vaccinations.
The high maternal antibodies level against Pasturellamultocidain vaccinated dams then in non-vaccinated dams antibodies levels in newly born buffalo calves remain effective for longer period.
This study suggested for the vaccination of dams not only for the protection of themselves but also for the protection of their newly born claves at the crucial period of their young age.

Comparision Of Synchronization Protocols On Estrus, Follicular Dynamics, Ovulation Time And Conception Rate in Sahiwal Cows
by Mubbashar Hassan | Prof. Dr. Nasim Ahmad | Dr. Aijaz Ali Channa | Dr. Aneela.
Material type: ; Format:

Publisher: 2013Dissertation note: Sahiwalcow is one of the established milch breed of zebu cattle (Bosindicus), known for heat tolerance and tick resistance in tropical and subtropical region which has its origin in Pakistan.Average milk yield is about 1500-2200 liters per lactation with 4.5% contents of fat (Shah, 1994).The population of Sahiwal cattle in Pakistan is decreasing over the past few decades due to change in agriculture system, indiscriminate crossbreeding and preference for buffalo. To minimize the cross breeding of Sahiwal cows, efforts have been made for its conservation, through management and genetic improvement. Significant genetic improvement, through artificial insemination(A.I) has been made. Fixed time artificial insemination (FTAI) has emerged in recent times which usually performed in association with a variety of estrus and ovulation synchronization protocols.Synchronization of estrus is actually the manipulation of estrous cycle or induction of estrus to bring large group of females in estrus at a programmed time. Three synchronization protocols were compared. In PG group, each animal was treated with luteolytic dose of PGF2? (d-Cloprostenol 0.150 mg; Dalmazine, Fatro®, Ozzano Emilia Italy; 2 ml; i.m) on random stage of the estrous cycle. In OVS group each cow received an intramuscular injection of gonadotropin releasing hormone (GnRH; 50 mcg of a GnRH analogue, DalmarelinTMFatro®, Italy; 2 ml; i.m) on random stage of estrus cycle (day 0). On day 7 these cows were treated with PGF2? (d- cloprostenol 0.150 mg; Dalmazine, Fatro®, Ozzano Emilia Italy; 2 ml; i.m), followed by second injection of GnRH on day 9. In CIDR group, each animal received an intravaginal Controlled Internal Drug Releasing Device (CIDR™; 1.38 g progesterone Eazibreed™; InterAg, Hamilton, New Zealand) on random stage of estrus cycle that was considered as day 0 of treatment. CIDR was removed on day 7 and on day 6 cows were injected with luteolytic dose of PGF2? (d-cloprostenol 0.150 mg; Dalmazine, Fatro®, Ozzano Emilia Italy; 2 ml; i.m).Estrus response and estrus intensity are higher in CIDR group but ovulation rate is less in CIDR and high in PG and OVS group. Timing of ovulation is shortest in OVS group as compared to other groups. Pregnancy rate are also high in OVS group. Therefore it is concluded that Ovsynch protocol is helpful to improve ovulation and pregnancy rate in Sahiwal cows.

Pathological Investigations Of Theileriosis (T.Annulata) In Cattle In Disteict Lahore Punjab

Publisher: 2014Dissertation note: Theileriosis is very important protozoal disease in crossbred cattle. According to an
assessment, about 250 million cattle are endangered by this disease and millions of high milk
yielding cattle are at risk of exposure to disease. It acts as a bigger restraint on livestock
improvement and production in many developing countries (Nagore et al. 2004). Theileria
annulata is the main specie that causes high morbidity and mortality. It causes heavy economic
and production losses in cattle in tropical and sub-tropical regions. The recorded mortality rates
in cattle reached to 70% (Moor house et al. 2001).
Theileria species are intracellular obligate hemoprotozoan parasites. All Theileria species
are dangerous and cause disease but two of them are important for livestock. Theileria parva and
T. annulata produces diseases named as East Coast fever and tropical theileriosis in cattle
respectively. Genus Theileria has many other species like T. buffeli, T. taurotragi, T. velifera, T.
sergenti and T. mutans. These species cause infections in wild and domesticated ruminants.
Theileria species present in large and small animals show signs like fever, anorexia,
swelling of the superficial lymph nodes, dyspnoea, lethargy, progressive anemia, constipation,
diarrhea, lacrimation and nervous symptoms (Saeed et al. 2010; Irvin and Mawmachi 1983). A
pronounced rise in body temperature, reaching 40-41.5 °C is pursued by lacrimation, depression,
swelling of the superficial lymph node and nasal discharge. The characteristic sign of tropical
theileriosis is anemia and finally haemoglobinuria occur with heavy weight losses. The clinical
course of the disease alter from per acute to acute or sub-acute to chronic (Oliveira- Sequeira et
al. 2005). The disease is lymphoproliferative in its early phases resulting enlargement of lymph
nodes, later on enters lymph destructive phase which is associated with a pronounced
Introduction
2
leukopenia. In the piroplasms phase in erythrocytes, the parasite becomes infective for the tick
(El-Deeb and Younis 2009).
Trans placental Bovine Tropical Theileriosis causing a deadly disease in a 3 day old
neonate cross bred calf and cerebral form of the disease (turning sickness) in a cow were
incriminated to T.annulata infection. It mainly depends upon the harmful effects of the T.
annulata on lymphoid tissues and susceptibility of the host (Sudan et al. 2012).
Theileriosis is prevalent in various regions of the world including Pakistan. It is transmitted by
Hyalomma species ticks. These ticks spread T. annulata which causes tropical theileriosis
(Durrani et al. 2009). The developmental stages of Theileria inside the Hyalomma ticks varies in
different shapes and forms (Hamed et al. 2011). Therefore to increase the milk and meat
production of cattle we can prevent the spread of the disease by controlling ticks
(Hekmatimoghaddam et al. 2012). The sufficient amount of Hyalomma ticks are found in warm,
commonly hard marshland and in central and Southern Europe, south west Asia and Southern
Africa having very long dry season. A toxin is produced in the adult ticks. This toxin produce
clinical signs of mucus membrane hyperemic and moist profuse eczema (Adam et al. 2000).
The sporozoites of Theileria enter into cattle host during tick feeding and they
immediately infect mononuclear leukocytes, these sporozoites develop into macroschizonts and
induce proliferation of the host cells. Macroschizonts constantly mature into microschizonts and
finally into merozoites, which are discharged from leukocytes. These merozoites attack
erythrocytes and mature into piroplasms, become available to ticks. Infective sporozoites,
injected during tick feeding, rapidly enter target cells, escape from the surrounding host-cell
membrane and differentiate to schizonts that interact with different host-cell components
(Dobbelaereand Rottenberg 2003). This interaction includes host cell signaling pathways that
Introduction

regulate proliferation and cell survival (Chaussepied and Langsley 2011) and thus cause
blastogenesis and clonal expansion of predominantly T and B cells (Fawcett et al. 1982; Baldwin
et al. 1988; Spooner et al. 1989). Merozoites released from these schizonts subsequently infect
red blood cells and become trophozoites. Lymphocytic stage of Theileria (schizonts) is the cause
of many of the severe disease manifestations like lymphadenopathy, pyrexia, thrombocytopenia,
and panleukopenia (Homer et al. 2000). Marked anemia, anisocytosis, pikilocytosis, and
leucopenia were commonly observed in bovine theileriosis (Ceci et al. 1997). Cattle may survive
the disease, but recovery and convalescence may be protracted and incomplete, this leads to
permanent debilitation, loss of productivity and prolonged carrier state. (Shahnawaz et al. 2011).
Cattle with subclinical infection in endemic regions become carrier of piroplasms and act as a
source of infection for the vectors (Brown 1997; Brown 1990; Uilenberg 1995).
The diagnosis of theileriosis in acute cases is majorly done on clinical signs and Giemsa
stained blood smears of cattle but the detection of agent is not reliable and is almost impossible
in carrier stage. Advances in molecular biological techniques have resulted in the improved
detection, identification, and genetic characterization of many hemoparasites. Species specific
polymerase chain reaction (PCR) has been developed for the detection and identification of
various Theileria species and has been shown to have higher sensitivity and specificity compared
with serological assays and examination of Giemsa-stained blood smears (Bhoora et al. 2009).
Primers were derived from the gene encoding the 30-kDa major merozoite surface antigen for T.
annulata (Aktas et al. 2006).
Most of the previous studies on haematological parameters in T. annulata infection were
carried out on experimentally infected cattle (Sandhu et al. 1998; Singh et al. 2001). The present
investigation was conducted to study haematological parameters in cattle naturally infected with
Introduction

T. annulata. Hematology has been broadly used in attempts to give information about disease
condition, performance problems and health in cattle (Rezaei and Naghadeh. 2006).
Hematological and sero-biochemical alterations are the indicators of severity of disease and are
considered to be good tools for the diagnosis, prognosis for effective therapy (Col and Uslu
2007; Nazifi et al. 2010b).
Lahore is one of the larger district in the Punjab province of Pakistan. Different cattle
breeds are reared by the people of the area for meat and milk production. The exact current
situation about the prevalence and pathogenesis of Theileriosis in the selected area is unknown.
The present study was conducted to screen cattle by finding schizonts or piroplasms in Giemsa
stained thin blood smears at slaughter house of district Lahore (Aktas et al. 2006) and later to
confirm through Polymerase Chain Reaction (PCR) (Chaisi et al. 2013) in order to implement
efforts and regulation to eradicate the spread of disease in the selected area. Data generated from
this study provided the latest status of Theileriosis, sex wise prevalence and its pathogenesis in
cattle population of Lahore. The study has also provided the necessary information to formulate
strategies for control of disease in the area. An investigation was also undertaken to ascertain the
changes in haematology as a result of Theileria annulata infection. These studies will help better
understanding of the pathogenesis and supportive therapy of this disease. Availability: Items available for loan: UVAS Library [Call number: 2186,T] (1).

Safety Level And Efficacy Of Controlled Release Urea On Performance And Health Status Of Nili Ravi Buffalo
by Muhammad Mobin (2007-VA-156) | Prof. Dr. Aneela Zameer Durrani | Dr. Jawairia Ali Khan | Dr. Nisar Ahmad.

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.

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
2
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: This study was conducted to compare the efficacy of Zental ( Albandazole) and Vermox (Mebandazole) against gastrointestinal nematodes like toxocara canis, toxocara mystax and toxascaris leonina in captive african lion (Panthera leo) kept in Lahore zoo, Lahor zoo safari, Bahawalpur zoo and Zain wildlife breeding farm Lahore because captive African lions are prone to different parasitic infestations.
A survey was carried out to estimate the prevalence of gastrointestinal nematodes in captive African lion and it was found that toxocara canis, toxocara mystax and toxascara leonina are the most commonly prevailing gastrointestinal nematodes in captive African lions in above mentioned places. The overall incidence rate of toxocara canis was 82.5 %, of toxocara mystax was 60% and of toxocara leonina was 50% respectively.
The Anthelmintics trials were conducted on 14 animals which were divided into 2 groups A and B each having 7 animals.
Group A was treated with Zental (Albandazole), group B was treated with Vormox (mebendazole), The percentage efficacy of each drug was determined on the basis of reduction on number of eggs per gram of discharged in faeces at day 7, 10, 13, 16 and 22 after deworming.
In group A, decrease in EPG of toxocara canis in group A was 21.1% at day 7, 37.2% at day 10, 54.7% at day 13, 74.6% at day 16 and 88.8% at day 22. Decrease in EPG of toxocara mystax was 15.9% at day 7, 38.1% at day 10, 56.6% at day 13, 70.6% at day 16 and 82.7% at day 22.similarly decrease in EPG on toxocaris leonina was 15.6% at day 7, 29.2% at day 10, 45.6% at day 13, 61.1% at day 16 and 83.1% at day 22 respectively
In group B, decrease in EPG of toxocara canis in group A was 7.24% at day 7, 14.57% at day 10, 23.26% at day 13, 31.27% at day 16 and 38.08% at day 22. Decrease in
Summary

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

hundred samples collected from Sargodha, Lahore and Okara districts of Punjab the prevalence of S. equi in horses and mules was 15%. Highest prevalence in equines was found at Remount Depot Mona, was recorded which is 18.3% followed by Okara 13.33%. No case was found to be positive for Strangles out of ten samples collected at UVAS, Lahore.
In-vitro antibiotic sensitivity test was performed on above isolates and it was found that ceftiofur Na was found to be most effective drug followed by norfloxacine and ampicillin. In vivo treatment trials showed that Group C animals treated with ceftiofur Na, norfloxacine, and ampicillin along with Vit E & Selenium supplemented by Phenyl butazone were found to be negative for post treatment carrier status. This study had aided in diagnosis as well as in treatment of strangles and was also provided us with the understanding of hematological parameters.
Statistical analysis:
Data on prevalence of S. equi in carrier animals were analyzed by Chi square test.
While comparison of different treatments trials was done by Z test.
Hematological parameters were analyzed by mean ± SED using SPSS software 16.0. Availability: Items available for loan: UVAS Library [Call number: 2299-T] (1).

Publisher: 2015Dissertation note: Freezing and thawing of semen leads to production of reactive oxygen species (ROS)
due to plasma membrane lipid peroxidation. Because of this semen quality can be
compromised. To overcome this problem, antioxidants have been used in cryopreservation
medium. Glutathione and cysteine have thiol groups which penetrate into the cell and protect
it from oxidative stress. In this study, effect of different concentrations of cysteine and
glutathione on post thaw quality of Sahiwal bull spermatozoa was determined.
Semen was collected with artificial vagina from five mature regular donor Sahiwal
bulls kept at the Semen Production Unit Qadirabad, Sahiwal. Semen samples possessing
>60% motility and >500x10
6
sperm/ml were included in study. After collection, semen
samples from five bulls were pooled, divided into seven equal aliquots and kept at 37 ºC in
water bath. After that dilution was done with Tris citric egg yolk extender having different
concentrations of cysteine and glutathione as Con (0.0 mM), C1 (1.0 mM cystein), G1 (1.0
mM glutathione), CG0.5/1(0.5 mM Cysteine+1.0 mM glutathione), CG1/0.5 (1.0 mM
cysteine+0.5 mM Glutathione), CG0.5/0.5 (0.5 mM cysteine+0.5 mM glutathione) and
CG1/1 (1.0 mM cysteine+1.0 mM glutathione). Diluted samples were cooled to 4ºC in two
hours and equilibrated for 4 hours at 4
o
C. After that they were packaged into 0.5 ml French
semen straws (20x10
6
sperm/straw). All semen straws were placed 4cm above liquid nitrogen
surface in vapors for 10 minutes. Then, semen straws were plunged into liquid nitrogen for
freezing and stored until post thaw analysis. The experiment was repeated for five times
(replicates = 5). Four semen straws/treatment were thawed for 30 seconds in water bath at
37ºC and evaluated for visual motility, plasma membrane integrity (PMI), acrosome integrity,
mitochondrial trans membrane potential and CASA motility parameters and kinematics.
42
Summary
PMI in group CG0.5/0.5 was significantly higher (40.00±1.42 %) as compared to Con
26.67±0.80 (P<0.5). Plasma membrane integrity in groups CG1/1, CG0.5/1, G1 and C1 was
significantly higher (36.00±1.88 %, 36.20±1.07 %, 33.60±1.21 % and 32.80±0.80 %
respectively) as compared to Con (26.67±0.80 %) (P<0.05). There was no significant
difference in C1 (32.80±0.80 %) and G1 (33.60±1.21 %) (P>0.05). In case of acrosome
integrity, NAR value of group CG0.5/0.5 was significantly higher (71.40±1.08 %) as
compared to Con (59.67±0.37 %) (P<0.05). All other groups also showed significant
differences as compared to Con (P<0.05). CG0.5/0.5 also showed significantly higher NAR
value (71.40±1.08 %) as compared to C1 (64.40±1.40 %) and G1 (67.60±2.07 %) (P<0.05).
CG0.5/0.5 had significantly higher value (71.40±1.08 %) as compared to CG1/0.5 and CG1/1
(65.60±0.81 % and 68.80±0.97 % respectively) (P<0.05). CG0.5/0.5 had significantly higher
subjective motility (54.00±1.88) as compared to Con (36.66±0.92)
Mitochondrial transmembrane potential of CG0.5/0.5 was significantly higher
(37.00±0.71 %) as compared to Con (25.33±1.28 %) (P<0.05). All the other treatment groups
also had higher mitochondrial transmembrane potential as compared to Con (P<0.05). In
groups of combination of cysteine and glutathione, CG0.5/0.5 showed significant difference
(37.00±0.71 %) as compared to CG1/1 and CG1/0.5 (29.00±1.00 % and 33.80±0.86 %)
respectively (P<0.05).
CASA results showed that CG1/1 had significantly higher motility as compared to the
control. But the percentage of progressive spermatozoa was significantly higher in
CG0.5/0.5. VSL of group CG0.5/0.5 was significantly higher (53.33±2.90 %) as compared to
Con (45.10±0.50 %). However, VSL, VCL, ALH and BCF did not vary significantly among
groups. STR and LIN of group CG0.5/0.5 were significantly higher as compared to the
control group.
43
Summary
In conclusion, addition of cysteine and glutathione in tris citric egg yolk extender
improved the post thaw quality of Sahiwal bull spermatozoa. In case of additive effect of
cysteine and glutathione, CG0.5/0.5 showed higher plasma membrane integrity, acrosome
integrity, mitochondrial transmembrane potential, progressive and rapid spermatozoa as
compared to CG0.5/1, CG1/0.5 and CG1/1.

Comparison Of Two Imported Live Attenuated PPR Vaccines In Local Sheep In Pakistan
by Saliha Saba | Prof. Dr. Aneela Zameer Durrani | Dr. Hassan Salem | Dr. Imran Altaf.
Material type: ; Literary form:
not fiction
Publisher: 2015Dissertation note: Peste des petits ruminants (PPR) also famous as goat plaque is of viral origin and is extremely contagious disease of sheep and goat (Dhar et al. 2002; Asim et al. 2009). PPR can cause high mortality about 50 – 80 % in non-immunized sheep and goat population. Due to its similarity with other diseases, Peste des petits ruminants (PPR) is being devalued but at the same time it is said to be one of the major constraints to successful small ruminant farming in tropics (Sen et al. 2010). PPR virus is paramyxovirus, enveloped and belongs to the genus morbillivirus. These viruses comprise of 16Kb long, single stranded RNA showing negative polarity (Barrett et al. 2005).
The various vaccines like homologous and recombinant vaccines have been manufactured for the management of Peste des petits ruminants (PPR), as no accurate treatment is available for its control. For the immunity of animals against this disease, the tissue culture based, attenuated rinderpest vaccine (TCRV) had been accustomed over a extensive period because of the antigenic association among RPV and PPRV (Diallo et al. 1989).With the help of fresh freeze-drying methods and stabilizing agents the thermostability of the present PPR homologous vaccine has been enhanced significantly (Worrwall et al. 2001).
In Pakistan, PPR vaccine was manufactured with the help of PPRV Nigerian 75/I (PPR 75/1 LK 6 Vero 75) for the sheep and goat immunization (Asim et al. 2009). India had manufactured numerous live attenuated vaccines like the PPRV Sungri/96 that has been regularized for use (Hegde et al. 2008). ). The Peste des Petits Ruminants (PPRV-Sungri/96 ) vaccine is being manufactured on small and large scale for prevention of Peste des Petits Ruminants (PPR) outbreaks in India (Singh et al. 2004).
Summary
41
The current study was designed to study the immunogenicity of two imported live attenuated PPR vaccines in local sheep. A total of sixty (60) animals were selected and further separated into two groups, viz. Group-A and Group-B, having thirty (30) animals each. Group-A was further sub-divided into A1 comprising 10 sheep to which Raksha PPR vaccine (Sungri 96) was administered, A2 comprising of 10 sheep to which PPR vaccine (Nigeria 75/1) was administered and A3 comprising of 10 non-vaccinated sheep which served as control. Group B was separated into two sub-groups i.e B1 and B2 having fifteen (15) animals each. The Group-B1 was sub-divided into B1a having 05 sheep to which Raksha PPR vaccine (Sungri 96) was only administered, B1b having 05 sheep to which along with Raksha PPR vaccine (Sungri 96), Vitamin AD3E was administered and B1c having 05 unvaccinated sheep which served as control.
Similarly the Group-B2 was sub-divided into B2a having 05 sheep to which PPR vaccine (Nigeria 75/1) was only administered, B2b having 05 sheep to which along with PPR vaccine (Nigeria 75/1), Vitamin AD3E was administered and B2c having 05 non-vaccinated sheep and served as control group respectively. The serum samples were collected and mean antibody titer was calculated by complement fixation test (CFT) at zero day, 7th day, 14th day, 28th day and 48th day post-vaccination.
The live attenuated, Raksha PPR (Sungri 96) vaccine induced the mean antibody titers of 0 ±0.00, 4.7±0.48, 4.7±0.48, 4.9±0.31 and 4.9±0.31 which was significantly higher than the mean antibody titers shown by the PPR (Nigeria 75/1) vaccinated animals i.e. 0±0.00, 3.3±0.51, 3.4±0.51, 4±1.15 and 4.1±1.19 at zero, 7th, 14th, 28th, 48th day post-vaccination respectively. Similarly the mean antibody titers shown by the PPR (Nigeria 75/1) vaccinated animals were 0 ±0.00, 10.4± 3.86, 11.2±4.13, 20±11.31 and 21.6±11.80 at zero, 7th,14th, 28th and 48th day post vaccination respectively. Result of present study demonstrated
Summary
42
that the mean antibody titer values of animals vaccinated with Raksha PPR (Sungri 96) was significantly higher than animals vaccinated with PPR (Nigeria 75/1) at zero, 7th,14th, 28th and 48th day post vaccination respectively. The study also concluded that the mean antibody titer of animals receiving vaccination along with vitamin supplementation was significantly higher than animals receiving only vaccination. While performing the statistical analysis of data, it was revealed that the results were significant (p<0.05).
The present study summarized and concluded that the mean antibody titer values of Raksha PPR (Sungri 96) was significantly higher than PPR vaccine (Nigeria 75/1). As both India and Pakistan are two neighbouring countries, so PPR among them also falls in trans-boundary disease category. It signifies that both being part of Asia subcontinent and PPRV strain of lineage IV prevails in both regions. Keeping these factors under consideration proper vaccination strategy should be followed for the immunization of animals. In past, Nigeria 75/1 strain of PPRV vaccine had been used in Pakistan but the results were not reliable in terms of desired immune response and protection. Although titer was shown by this vaccine but protection is not reliable for proper health care of small ruminants. There was an immense need to come up with the authentic research on PPRV vaccine Raksha PPR (Sungri 96) in Pakistan which is already being used in India with desirable results.
The results of present research project were mostly similar with the findings of other scientists. The results of this study were analyzed through Independent t-test for independent samples. Availability: Items available for loan: UVAS Library [Call number: 2385-T] (1).
