; Nature of contents: ; Literary form: Publisher: 1998Dissertation note: Mid shaft tibial fractures can be repaired by external and internal methods of fixation. The internal methods include bone plates, bone screws, intramedullary pins, circiage wires etc. whereas external fixation devices include K.E. apparatus, Thomas splint, P.O.P. (Gypsona cast splint) other casts and fixation devices. In the cases of mid shaft tibial fracture in the dog, it is not necessary all the times to repair it by internal methods of fixation. External methods of fixation are comparatively cheaper and easy to apply and handle and prevent the animal from the post-operative complications of internal methods of fixation.
The present study was launched for the comparison of the external fixation devices used for the repair of mid-shaft tibia fracture in the dog i.e.
a) Gypsona cast splint.
b) K.E. apparatus.
c) Thomas splint.
The study was carried out on 12 mongrel dogs of either sex divided into four groups i.e. A, B, C and D and each groups comprising three animals designated as I, II and III. In group A, after the induction of mid shaft tibial fracture Gypsona cast splint was applied on right limb. In group B, K-E. apparatus and in group C Thomas splint was applied. The group D was held sham operated (control) after the induction of mid-shaft tibial fracture. The aforesaid devices were first applied on right tibia and then on left tibia of the same dog at an interval of 10 weeks. The dogs were kept in kennels for 20 weeks. At the end of experimental period, the dogs were euthanized and gross examination was conducted.
The results were collected on the basis of clinical examination (lameness) radiographs and post-euthanasia findings. The results clearly revealed that K-E. apparatus was the best choice in cases of mid shaft tibial fracture in the dog, in terms of best immobilization and good calus formation. Although K.E. device is costly one, but it won't exceeds the cost of the animal in many cases. The results were excellent and procedure can easily be applied easily by an average Orthopaedic surgeon. Thomas splint comes next to K-E. apparatus. If properly applied gives good results. Gypsona cast splint was graded at the end, due to its less efficacy and accuracy. It usually resulted in bone bending after application. It could have been a better procedure if applied with some metallic cast or splint.

Publisher: 1998Dissertation note: One hundred and fifty brioler chicks reared under standars and managmental conditions, were divided into five groups A, B, C, D and E each comprising 30 birds at the ag of 21 days. From 22nd day to onward group A, B and C were given feed mixed with coccidiostats i.e. diclazuril (200mg/kg of feed), maduramicin ammonium 500mg/kg of feed) and salinomycin (1gm/kg of feed) respectively till the end of experiment while group D and E were fed with usual feed. On 28th day, the group A, B, C and D were infected with 75000, sporulated occyst/bird while gropu E was non-infected non-medicated control.
Clinical signs were observed only in group B, C and D. The total oocyst count in all groups on zero day of infection was zero. On 1st, 4th and 8th day after the appearance of clinical symptoms, the total oocyst count in group A, B, C and D were 2500, 4900, 9700 and 209600 respectively, while group E examined nil being control non-infected group. Morbidity observed in group B, C and D was 3.33% 16.66% and 83.33% respectively while in group A and E morbidity was not observed. Mortality was observed only in groups C and D that was 3.33% and 30% respectively.
The feed intake and feed conversion ratio of group A, B and C was almost equal, while of group D (infected and non-medicated) is concerned it showed better result. Postmortem examination revealed severe enteritis an hemorrhagic lesions in small intestines and caeca, while on histopathology, damage to the absorptive tissue and destructions of the intestinal villi alongwith the merozoites, schizonts and gametocytes in the mucosa and sub-mucosal region of intestine and caeca were observed.
The study showed the prophylactic efficacy of diclazuril, maduramicin ammonium and salinomycin in descending ordre respectively. Diclazuril was to be the drug of choic against coccidiosis.

Publisher: 1998Dissertation note: The study was conducted to determine the prevalence of genus trypanosome and the effects of natural infection on some blood parameters in dogs.
For this purpose blood samples of 500 pet dogs (250 adult dogs and 250 pups) were examined at Dog Hospital, College of Veterinary Sciences, Lahore. Giemsa staining procedure was admpted to stain glass slides having blood smears made from blood samples.
Out of 500 ogs, 30 dog were found positive for tryponosomiasis. It revealed that only 6% prevalence of trypanosomiasis in dogs was estimated. In case of adult dogs out of 250 dogs, 13 dogs (5.2%) and in pups out of 250 dogs, 17 dog (6.2%) were found trypanosome infected. So pups were found more susceptible as compared to adult dogs. During research it was also noticed that mot of the dogs which were found positive being kept with horses.
Then blood samples of 10 adult dogs and pups each which wre positive for trypanosomiasis and 10 adult dogs and pups each which were healty (as control) were further examined for the estimation of haemoglobin paced cell volum, erythrocytes sedimentation rate and total serum protein to check the effects of natural infection on mentioned blood parameters.
The blood parameters of trypanosome infected and healthy adult dogs were compared and similarly blood parameters of trypanosome infected and healthy pups were compared. For this comparison unpaired 't' test was applied. By calculation it was found that haemoglobin, packed cell volume and total serum protein of trypanosome infected adult dogs and pups were significantly decreased as compared to healthy adult dogs and pups, respectively. But the erythrocytes sedimentation rate was found significlantly increased in case of trypanosome infected adult dogs and pups as compared to healty, adult dogs and pups.

Publisher: 1999Dissertation note: The present study was conducted to see the effects of the experimentally induced coccidiosis on weight gain and some blood parameters and its control with medication and vaccination. For this purpose, 150 day-old quail chicks were purchased from the local hatchery and were reared under control managemental and coccidiosis free condition upto the 42 days of experiment. A commercial coccidiostat free feed and drinking water were provided ci libitum throughout the experiment. The birds were divided in five separate groups i.e. A, B, C, D and E, each comprising of 30 birds. Group A was kept as a non-infected, non-medicated and non- vaccinated. The chicks of groups B, C, D and E, were administered 50,000 oocysts of. tenella directly into the crop at the 18 days of age, the chicks in group C were immunized against coccidiosis with a locally prepared vaccine on 3rd and 10th day of age, while those of group D with an imported coccidiosis vaccine (Coccivac) on 7th day of age. The chicks of group E were medicated with Salinomycin on the appearance of clinical symptoms and OPG of the infected birds.
No oocysts were seen in the droppings of group A chicks, throughout the experiment, while group B, chicks had the highest OPG count after induction of infection, the highest peak being in the 3rd week post-infection.
The highest mortality recorded in the infected B group and low in other infected C, D and E groups and highest mortality in 3rd week of induced infection in all infected groups.
The birds in groups A and E attained highest weight gain as compared with groups B, C and D but the difference was non significant.
The lowest Hb and TEC values were recorded in infected group B, while in other infected groups C, D and E both these values were also decreased but comparatively lesser than B group. Similarly, values of TLC were increased in infected group B as compared with other infected groups i.e. C, D and E and the difference was statistically significant.
In case of differential leukocyte counts there were increased heterophil and monocytes values in group B, while decreased values lymphocytes, basophils and eosinophils were recorded in other infected groups than the other i.e. C, D and E.
The postmortem lesions observed were swollen intestines petechial haemorrhages on the wall of the intestine and dehydrated liver and lungs in infected carcasses.

Publisher: 2000Dissertation note: The present study was conducted between November 1999 and January 2000 to find out the prevalence and to study the taxonomy of haemoparasites of horses. In addition, their effect on haematological parameters was also studied.
A total of 40 out of 435 horses were found positive for haemoparasites. The prevalence recorded was 9.20%. Out of positive animals 22(5.06%) were positive for babesia species, of which 10 (45.45%) were infected with B. equi, 6 (27.27%) were infected with B. caballi and 6 (27.27%) were positive with mixed infection of B.qui and B. caballi. out of remaining positive cases, 14 (3.22%) were positive for T.evansi and 4 (0.92%) were positive for P.multipapillosa.
Animals of group A, belonged to all the places of other groups. Animals of group B showed 10.52 % prevalence for haemoparasites, Babesia species was present in 6 (6.3l%) and T.envansi was present in 4 (4.2l%) animals respectively. Horses of group C showed prevalence as 14.28% haemoparasites out of which 6(8.57%) were positive for babesia species, and 4 (5.71%) positive for T.evansi . Similarly, animals in group D, indicated 11.11 % prevalence of haemoparasites including babesia species 3 (3.33%), T.evansi 3 (3.3%) and P.multipapillosa, 4 (4.44%) respectively. Ten out of 180 (5.56%) horses of group E were positive for haemoparasites and 7 (3.89%) were positive for Babesia spp. and 3 (1.66%) were positive for I.evansi.
Haematological examination revealed a significant decrease (P<0.05) in the total erythrocyte count, total leukocyte count, haemoglobin estimation, packed cell volume, neutrophils and basophils in the infected horses as compared with healthy horses. However, there was a significant increase (P<0.05) in lymphocytes and eosinophils in the infected horses as compared with healthy horses of group A.
From the results of the present study it may be concluded that the horses belonging to the poor community need due attention for the control of haemoparasite diseases. Services must be extended to educate owners of these Tonga ponies for the control of haemoparasitic diseases and their vectors.

For this purpose 151 compound stomachs (70 buffaloes and 81 cattle) of slaughtered ruminants were examined at Lahore abattoirs. The worms were collected and identified and taxonomical findings were recorded. In addition, faecal samples from the positive cases were also collected and examined to record the EPG count. The blood samples were also collected from the above mentioned animals to study the effect on different haematological parameters. The animals awaiting slaughter were selected irrespective of age and sex.
A total of 70 buffaloes and 81 cattle had to be examined to obtain the 50 positive buffaloes and 50 positive cattle, infected with different species of amphistomes. The overall incidence of amphistomes was found to be 71.42% in buffaloes and 61.72% in cattle.
The various species of gastric trêmatodes identified were as follow i.e. Paramphistomum cervi, Cotylophoron cotylophorum, Gastrothvlax crumenifer and Carmverius spatiosus. The incidence of . cervi infection was higher both in buffaloes (54.48%) and in cattle (44.34%) as compared with the other species of the family Paramphistomatidae. The incidence of Cotvlophoron cotylophorum was found to be 50% in buffaloes and 39.5% in cattle. The incidence rate of Gastrothylax crumenifer and Carmyerius spatiosus was found to be 38.57% and 28.57% in buffaloes while 29.62% and 19.75% in cattle respectively.
The EPG of affected buffaloes and cattle carcasses was also undertaken and the average EPG recorded was 44.67 eggs/gram in buffaloes and 39.78 eggs/gram in cattle.
Haematological findings revealed that the Hb, PCV and TEC were decreased while the neutrophils and eosinophils were increased both in buffaloes and cattle suffering from amphistomiasis.

Publisher: 2001Dissertation note: The study was undertaken to find out the comparative efficacy of Phenothiazine, levamisole and Ivermectin against GIT nematodes in horses at Lahore. For the purpose one hundred horses irrespective 'of age, breed and sex were exam for the presence of various species of gastro-intestinal nematodes in horses. The coprological examination showed a positive percentage of 64% while 36 cases (36%) were found to be negative. The positive cases had mixed infestation of large and small strongyIids, Parascaris equorum and Oxyuris equi species. Forty naturally infested horses divided in four groups (A, B, C and D), were selected for the drug trial. The drugs used were Phenothiazine @ 55 mg/kg body weight, levamisole @ 7.5 mg/kg body weight (1 mI/2 kg b.w) Ivermectin @ 0.2 mg/kg body weight to the groups A, B, C and D, while the animals of group D acted as non-medicated control.
The mean EPG count was carried out pre-medication and post medication of the said anthelmintics.
Based upon EPG count, conducted on 3rd, 7th and 14th day for each anthelmintic; it was revealed that the mean EPG count of group A (Phenothiazine) showed 62.99, 82.67 and 95.27% reduction in ova output while the animals of group D (medicated with levamisole exhibited 53, 82 and 93% reduction in the said equines). The group C (medicated with Ivermectin showed reduction ofEPG as 79.83,95.16 and 100% on 3rd, 7th and 14th day post medication).
From the results of this study it is concluded that Ivermectin was the most effective as compared to Phenothiazine and levamisole. Therefore, it is stressed that Ivermectin should be used in equines for the effective control of gastro intestinal nematodes. The drug is quite safe and without any adverse effects on these animals.

Publisher: 2000Dissertation note: The study was designed to look into the comparative efficacy of different prophylactic measure against coccidiosis in broilers. One hundred and fifty, day old broiler chickens were reared under controlled conditions. They were equally divided into five groups, on day 1, i.e. A, B, C, D and E. Group 'A' was kept as uninfected, unmedicated control whereas all other test groups B, C, D and E were infected with 30,000 sporulated virulent oocysts. Group 'B' acted as infected and unmedicated control at day 20 and 30 of age. Group 'C' acted as infected and treated with Diasul-S at the rate of 1/2 gm/lit of drinking water for 3 days and group 'D' was treated with coxicure A-K at the rate of 1/4 gm/lit drinking water for 3days. The birds of group E received locally prepared Eimeria tenella vaccine (ETV) on day 3 and 10 of age of birds.
No coccidiosis in the birds of group A and E was noted through out the experiment. The oocysts per gram (OPG) of faeces in group A and E was nil Members of group 'B' showed the highest counts than any other group. The birds of group 'C' and 'D' showed the moderate counts but towards the completion of experiment, the OPG counts gradually reduced in both groups.
Weekly average weight gain record showed that average weight gain by the birds of group 'A' were the highest as compared with all other groups. The average weight gain of group E showed the second highest weight gains. The members of group 'B' showed the lowest weight gains while the members of groups 'C' and 'D' were ranked as 3rd and 4th in weight gains. The weight gains observed in groups A, C, D and E as compared with groups B were significantly higher (PO.O5) N. P.. In groups 'A', 'C' and 'E' the morbidity was nil. While in groups 'B' 30% morbidity was observed. Group 'D' showed low morbidity and one bird died due to coccidiosis.
The best feed conversion ratio (FCR) was observed in groups 'A' and followed by groups 'E', 'C' and 'D'. The feed conversion ratio in groups 'C' and 'D' was equally good. Worst feed conversion ratio was observed in group 'B'.

Publisher: 2003Dissertation note: Present study was conducted to investigate the production of immune yolk against multiple avian viruses and effect of physicochemical factors on its keeping quality. It was observed that peak antibody titers in the yolk of eggs laid by the birds vaccinated against avian viruses (Newcastle disease virus-NDV, infectious bursal disease virus-IBDV, avian influenza virus-AIV-H9 and hydro pericardium syndrome virus-HPSV) were attained on 4 weeks post-boosting which were maintained over subsequent 6 weeks and started declining thereafter. The immune yolk treated with chemicals (antibiotics, sodium azide and formaldehyde) was stored at room temperature, refrigerator and freezer. Any change in physical properties (color and odor) and antibody titer of the yolk was determined at day 0, 7, 14, 22 and 30 post-storage.
Antibiotics (penicillin, streptomycin and gentamycin) in the yolk during storage at room temperature inhibited the bacterial growth but permitted fungal growth that induced physico-chemical changes such as change in color, development of bad smell and reduction in antibody titer. Antibiotics / sodium azide treatment and freezing / refrigeration for more than 30 days showed undetectable change in antibody titer of the immune yolk. However, formaldehyde
in the yolk during storage at -20°C precipitated its proteins leaving clear fluid free from the antibodies.
Effect of chemically treated stored immune yolk was investigated on the recovery of Newcastle disease virus (NDV) infected layer cockerels (35 days old). Antibiotics and sodium azide treated fresh and stored immune yolk (at 4°C for 15 days) containing 64 units of anti-ND V-haemagglutination inhibition (HI) antibodies showed 100 percent protection in the birds. The immune yolk treated with the same chemicals and stored at -20°C for 30 days also showed 100 percent protection. However, antibiotics and sodium azide treated yolk (containing same titer of the antibodies) stored at 4°C for 30 days showed 70 percent and 90 percent protection, respectively. It is inferred that sodium azide in the immune yolk during storage at 4°C or -20°C might have preserved antibodies and hence such yolk may be used for passive immunization to treat the virus infected birds.

Publisher: 2004Dissertation note: This project was designed for the Chemotherapeutical and Haematological studies of induced coccidiosis in pigeons. For this purpose three anticocidials were used. These were ancoban (Amprolium), Supercoc (Sulphaquinoxaline) and Phytocox (Herbal Product). These were used alone and with the addition of vitamin A and K. Some Haematological Studies were also done i.e. total Leucocytic Count (TLC), differential leucocytic count (DLC) and Haemoglobin (Hb) estimation.
One hundred and twenty healthy young pigeons were obtained and were provided coccidiosis free feed. These pigeons were divided into eight groups viz; A, B, C, D, E, F, G, and H comprising 15 birds each. 30,000 viable sporulated oocysts were inoculated directly into the crops of pigeons of group A to G.
The medication was started on day 4 post-inoculation of oocysts. Group A, B and C were given Ancoban, Supercoc and Phytocox, respectively. Groups D,E and F were given Ancoban, Supercoc and Phytocox (Herbal Product), respectively with the addition of vitamin`A and K. The Group G was infected, untreated control while group H was uninfected, untreated (Healthy) control. The clinical signs were more pronounced in the groups that were treated without the addition of vitamin A and K.The highest efficacy of the drug was found in group E which was 99.36%.
Haemoglobin estimation was done on day 0, 4, 9 and day 14. It was concluded that haemoglobin values were decreased after clinical signs had appeared. Total leucocytic count was also done on day 0, 4, 9 and day 14. There was increase in TLC after infection had occurred and started to decrease after day 9. The differential leucocytic count, lymphocytes decreased while heterohils and monocytes were increased and eosinophils and basophils showed variation in their number was compared to control group. The oocyst count was done on day 4, day 9 and day 14 post-inocultion of oocyst. The efficacy of the drug given to the group E was 99.40% which was the best among all the groups.
The result of the present study showed that supercoc (sulphaquinoxaline) with addition of vitamin A and K was comparatively better drug for the control and treatment for cocidiosis in pigeons.

Publisher: 2005Dissertation note: This study was conducted to work out the prevalence of gastrodiscus infection in Lahore area and to check the comparative efficacy of one patent (Albandazole) and two Herbal Drugs i.e. Melia Azadarch Linn (Neem) and Nigella Sativa (Kalonji) against Gastrodiscus infection in Horses and its effect on various blood components including Hb, TLC, and DLC the purpose of this experiment was tomention extensive Pharmacological Experimentation on indigenous drug which result in the discovery of some potent Anthelmintic Drugs which would be a break through in limiting Gastrodiscus infection in horses. Furthermore, it could contribute to the improvement of our economy by making an industrial use of these resources and by saving foreign exchange via exporting these medicines abroad. In addition to these, studies were expected to contribute to the rationalization of Eastern / Unani system of Medicine, practiced by HKIMS and SIANAS.
To accomplish the study six hundred faecal samples of horses were collected and coprologically examined by fresh smear method to determine 40 naturally infected horses by Gastrodiscus infection.
The 40 infected animals were divided into four groups i.e. group A, group B, group C, and group D comprising 10 animals. Each groups A, B and C were treated with Albandazole, Melia Azadarch Linn (Neem) and Kalonji, respectively were as group D was control and remain untreated. The prevalence of Gastrodiscus infection at Lahore areas was found to be 6.6%.
The Egg per gram (EPG) counts was estimated by using Macmaster technique at zero day (pre-medication), 3rd day, 7th day and 10th day (post-medication). Groups A, B and C were treated with Albandazole, Neem and Kalonji seeds dose rate of 10ml/10kg body weight, 500 mg/kg body weight and 1gm/kg body weight, respectively.
After medication at 3rd, 7th and 10th day EPG count was measured. It was observed that at 3rd day, Albandazole Neem and Kalonji showed the efficacy 50%, 4769% and 9.09% respectively.
At 7th day, the efficacy of albandazole neem and kalonji was found to be 66.66%, 53.84%, 20% respectively.
At 10th day, the efficacy of albandazole Neem and Kalonji was found to be 95%, 60% and 27.27, respectively.
The average efficacy of Albandazole Neem and Kalonji was found to be 70.5%, 53.6% and 18.78%, respectively.
Hence, Albandazole, and Neem showed better results as compared to Kalonji. It was concluded that Albandazole and Neem were safe against Gastrodiscus in Horses.
HAEMATOLOGY
In the present study forty blood samples from naturally infected horses with different intensities of infection were examined for haematological studies to know the changes in the blood picture due to Gastrodiscus. The blood samples were collected premedication i.e. on Zero day and then on 3rd, 7th and 10th day post-medication.
A marked decrease in haemoglobin was observed after the study of infected animals on Zero day. The normal haemoglobin value was 10.5 to 15.5 g/dl. This value became near to normal on 7th day post-medication and went on increasing upto 10th day as the ova count in the faeces was decreasing.
The study regarding the total leukocytic count concluded a mild increase values of TLC, but after treatment these values decrease to normal level as the ova count in the faeces was decreasing.
The haematological finding of the present study are in complete accordance with the results of Chaudhry et al., (1991) and Peal et al. (1989). The reported that there was decrease in hemoglobin values of infected animals as compared to healthy animals. It is tempting to speculate that the decrease in haematological values may be due to the blood sucking habit of the parasite.

Publisher: 2004Dissertation note: The study was designed to compare the efficacy of different ionophore, chemical and herbal anticoccidials in broiler ration. A total of 320 day-old broiler chicks were purchased and raised for 42 days in good hygienic and husbandry conditions. The birds were randomly divided into eight groups i.e. A, B, C, D, E, F, G and H having 40 birds in each group. These groups were further subdivided into four replicate of each group comprising of 10 birds per replicate.
Group A was uninfected unmedicated control, while the group B was infected unmedicated control. Group C was given feed additive anticoccidial Kokcisan (salinomycin Na 12%). Group D was given Diclacox (Diclazuril 0.5%) as feed additive. Group E was given Decocci (Meduramycin 1%) in feed. There was Clopidol (10%) mixed in the feed of group F. Group G was given a herbal anticoccidial Coxigon. Group H was given anticoccidial feed additive Avatec (Lasalosid Na 15%) in the ration.
All the groups except group A were given challenge dose of infection on 22nd day of age. The faecal samples were collectd on 5th, 6th arid 7th day post-infection and oocyst count was done. Feed consumption and weight gain were recorded on weekly basis. Clinical signs were noticed, record of mortality was maintained and postmortem of dead birds were also performed. The data collected was statistically analyzed by ANOVA and LSD test, to detect the difference between treatments and mean.
It was concluded that Coxigon 3 kg/ton of feed had excellent activity in term of oocyst count, reduction of lesions, and FCR as compared to all other groups, Kokcisan (salinomycin Na 12%) showed better results than any other ionophore or chemical anticoccidials used and stood second behind coxigon. These results will help the feed manufacturers regarding use of best feed additive anticoccidial in broiler rations.

Publisher: 2005Dissertation note: The study was designed to compare the efficacy of different anticoccidials i.e. Coxigon and Toltrazuril and their effect on blood values in quails. A total of 100 young healthy quails were purchased and raised for a week in good husbandry and hygienic conditions. The birds were randomly divided into four groups i.e. A, B, C and D, comprising of 25 birds each. Group A was treated with Toltrazuril, while group B was treated Coxigon. Group C was infected, non medicated and group D was uninfected control group. All the groups except D were given primary challenge doses of infection. The oocysts count was done on day zero, 3, 5 and 7. Record of mortality, morbidity was kept and postmortem of dead birds was also performed. The data collected was subjected to statistical analysis using one way analysis of variance and least significant difference (LSD) test, to detect the differences between the treatments and means. It is concluded that Toltrazuril as anti-coccidial revealed significant (P<0.05) difference among all the treatments in terms of weight gain, feed efficiency, oocyst count, reduction and decrease in mortality ratio and help a lot to normalize the blood values of quails. The results of other anti-coccidial i.e. Coxigon was not satisfactory, due to less decrease in mortality ratio, feed intake and weight gain and help little to normalize their blood values, and group C was infected non medicated showed great mortality and morbidity rate as compared to other groups. The results of this study will help to the Feed Farmers in choosing the best anti-coccidial drug, while the farmers will get choice amongst anti-coccidial drugs.

For this purpose 180 sheep and goats naturally infected coprologically were examined. Out of 180 sheep and goats 106 were found positive showed 58% prevalence. For the treatment protocol, forty naturally infected and ten non-infected were selected and divided randomly into five groups having ten sheep and goats in each group viz A, B, C, E and D. Group A was treated with Albendazole 1ml/20mg body weight. Group B was treated with Oxfendazole 1ml/5kg body weight. Group C was treated with Karanjwa (Caesalpenia crista) @ 2mg/kg body weight. Group E was kept infected non-medicated control group. Group D was kept non-infected non-medicated control group.
In group A the eggs per gram of faeces were 22,700 on day zero and no eggs were found on day 7th which was treated with Albendazole. It has been observed from the result that Albendazole showed 100% efficacy on day 7th. In group B which was treated with Oxfendazole with egg per gram of faeces were 23,200 on day zero 22,800 on day 7th and no egg were found on day 14th. It has been observed from above results that the Oxfendazole shown 95% efficacy on day 7th and 100% efficacy on day 14th. In group C which was treated with Karanjwa, the eggs per gram faeces were 19,500 on day zero 22,100, on day 7th 31,800 on day 28th. Group E which was kept infected non-medicated control group, the egg per gram were found on day zero, 7th, 14th, 21st and 28th, 20000, 23700, 27500, 31200 and 35300.

Simplication Of Urea Treatment Method To Improve The Nutritve Value Of Cereal Starw
by Muhammad Haroon Muzaffar | Prof. Dr. Makhdoom Abdul Jabbar | Dr. Anjum Khalique | Dr. Kamran.
Material type: ; Format:

Publisher: 2005Dissertation note: In Pakistan about 36 million tones of rice and wheat straw is produced annually which constitutes an important part of livestock feeding. Cereal straws have low protein contents and low digestibility. Hence, inspite of large volume they contribute little towards meeting the nutritional requirement of livestock. In the past, efforts have been made to improve the nutritive value of straws through chemical treatment which included use of NaOH, anhydrous ammonia and hydrogen peroxide with different levels of success. Lately urea has been used for increasing the digestibility and protein contents of straws. However, inspite of significant improvement in the nutritive value by this method the adoption of technology by the farmers always remained low. Reason for low adaptability may be due to relatively tedious technology and involvement of labour.
The conventional method of urea treatment of straw involves preparation of 4% solution of urea in water, sprinkling this solution on wheat straw layer by layer and simultaneously pressing the wheat straw to give it anaerobic condition and finally covering it with mud plaster or plastic sheet and incubation for a period of one month before its use. Limitation of this method is the involvement of labour especially when larger quantities of straw are to be treated.
To overcome this problem a new simple and easier method has been developed. This method involves weighing of urea @ 4% of straw to be treated, mixing it with the double the amount of manure or Acacia leaves, giving some moisture by adding water, putting this mixture in bag, keeping the bag on ground where straw is to be treated, piling the straw on bag, again moistening the straw with water (60% of straw) and incubating this material for one month under the cover of plastic sheet or mud plaster.
The method is slightly less efficient than the conventional one but very simple and involves very little labour as compared with conventional one. In the new method three steps including preparation of urea solution, sprinkling of solution on straw and pressing the straw during treatment process have been deleted which resulted in saving labour and time.
CONCLUSION
As a result of this study a new and easy method has been developed which is simpler and involves much lesser labour than the conventional one. In this method following three main steps have been excluded which are used in the conventional method.
a) Preparation of 4% urea solution.
b) Sprinkling and mixing of urea solution with wheat straw.
c) Pressing the wheat straw to give it anaerobic conditions.
Method is slightly less efficient than the conventional one and demands more research work. The new method may be named as "Bag Method".

Publisher: 2006Dissertation note: To final out the comparative efficacy of different control measures against Argas persicus, In-Vitro and In-Vivo studies were carried out for the in-Vitro studies three thousand soft ticks Argas Persicus at different stages of their development were used in the experiment. The ticks were divided in to 5 groups A, B, C, D and E having 600 ticks in each group. The ticks of each group (600) were further divided in to three replicates having 200 ticks in each. The ticks were maintained in small plastic boxes containing tick rearing medium at a controlled temperature of 25 Co and 60% relative humidity. The 5 treatments are applied with a small (1 liter) hand held sprayer at the rate of 20ml per box 345 cm2 surface area. The first application was made after 24 hours and repeated twice at 48 hours intervals. On day 0,3,5,7 and 10, the ticks were separated from the manure by immersing the manure in water and retrieved the ticks with the help of sieve. The ticks relating to each group were counted and the counts of each group were compared. The reduction in the counts in test groups as compared to control group A indicated the efficacy of the treatment. It was noticed by the comparative mortality of the ticks in the replicates of different groups that in mortality of ticks in Group A occurred as 6.17% in B as 67.67% in C as 70.67% , in D as 100% and in E as 71.83%. The findings of the In Vitro experiment showed that the efficacy of Tiekide was 100% and in ranking order was placed at No. 1 amongst the test groups and the difference was statistically significant (P<0.05) as compared to B, C and E groups. However the findings of Groups B, C and E were not significant amongst each other (P>0.05). For the In-Vivo studies, the experiment was conducted on a layer farm infested with Argus persicus. A total of 100 layers infested with Argas persicus were reared under experimental conditions on particular farm. One hundred infested birds were divided into 5 groups i.e A,B,C,D and E, each group consisting of 20 birds. The ticks of all members of the groups were counted on day 0,3,5,7 and 10. Group A acted as infested and non treated, B was treated by application of EM1 under the infested wings, C was applied EM5, D was applied Tiekide (Homoeopathic formula) under the wings the medicine was also orally administered @ 2 drops in 1 ml water and members of Group E were applied 1% solution of Ivomec (Ivermectin). The results indicated that the reduction in the mean tick counts was 95.74% in Group D which was placed at No. I, in descending order the mean tick counts reduced by 70.97% in Group E, 68.59% in Group C, 67.63% in Group B and only 1.93% in control Group A. The Tiekide was claimed to be a drug of choice.

Publisher: 2004Dissertation note: This project was planned to study the effect of storage, pre heating & turning during holding period on the hatchability of the eggs of broiler breeder of 32 weeks. For this purpose 240 feritle eggs (52-5 gm weight) of 32 weeks old breeding flock were purchased form a reputable hatchery. After collection the eggs were cleaned and stored at specific temperature (16 C) and humidity (75%). Eggs were equally divided into four groups i.e. A, B,C, and D having 60 eggs each. The eggs of group A were neither turned nor preheated before setting in the incubator. The eggs of group B were preheated for 6-7 hours until the temperature reached 85 F before setting in incubator but were not turned. The eggs of group C were not pre heated but were turned for 6-8 times in each day during storage period before setting in the incubator. The eggs of group D were pre heated before setting in incubator and turned simultaneously during holding period (storage period). After these specific treatments the eggs were placed in the incubator for 21 days. After the incubation the hatchability percentage of all the groups were noted and the chicks were brooded for 8 days. At the end of second week of age the FCR, weight gains total feed consumed and common causes of mortality were calculated. The data was subjected to statistical analyses (2 x 2 Factorial, Steel and Torrie 1980). Statistical analyses of the data revealed that no differences were obsedved amongst the groups in case of pre heating but in case of turning there was a significant diference (P<0.05) among those groups for hatchability percentages. Although the hatchability percentage for the group D was highest than those of groups A, B, and C. The groups were significantly different in case of weight gain in first week of age. The group D showed significant difference (P<0.05) from the group A. In case of FCR in first and second week of age there was no significant difference (P<0.05) among the all groups i.e. A,B,C and D. The weight gain in second week of age did not significantly showed a difference (P<0.05) among the groups A,B,C and D. The early mortality percentage was highert in group A and lowest in group D. This shows that the turning has a major effect to reduce the sticky chick number. The over all results showed that as we give the turning to the fertile eggs the day old chick weight, weight gain in first week of age and number of sticky chicks were reduced and healing did not contribute to the day old chick weight, weight gain and FCR but reduced the early mortality losses.

Publisher: 2006Dissertation note: Food borne trematode infections have been recently identified as an important public health problem having considerable economic impact in terms of morbidity, loss of productivity and health care costs. Fish serve as second intermediate host of food borne trematode infections and serve as direct source of infection in humans. In the present study four different species of fish i.e. Labeo rohita (rohu), Cirrhnuh mrigala (mori thela), Catla catla (thela) and Hypophteamicty thyesmolitris (silver carp) serving as intermediate hosts of food borne trematodes were identified and also recorded the prevalence and intensity of infection due to metacercariae of food borne trematodes in common food fishes of Pakistan. For this purpose 222 different samples of fish were collected from numerous water bodies i.e. Rawal Dam, Islamabad and Mangla Dam, and local fish markets and detection of infection metacercariae of opisthorchis/clonorchis and heterophyids by pepsin digestion technique. Overall infection rate was 28.37 percent species wise prevalence indicated that catla catla and Labeo rohita were more frequently affected than other so whereas the lowest (23.5%) prevalence was reported in Hypophteamicty thyesmolitris. As the people of Pakistan are not consuming raw or undercooked fishes so prevalence of zoonotic diseases transmitted from fish are not recorded in Pakistan. However, experiment conducted on mice indicated that when metacercarial infection was given to mice, adult worms were isolated from the mice.

Publisher: 2007Dissertation note: Malathion is an organophosphorous compound widely used as pesticide, mostly in spray form. The present project was designed to study the effect of Malathion on lipid profile and inhibition of cholinesterase activity in rabbits. The experimental rabbits were kept at the animal shed of Department of Pharmacology and Toxicology and were divided into five groups A, B, C, D, and E, each comprising of five animals. All the animals of each groups were shaved from their dorsal side for the application of Malathion. The animals of group A were treated with Malathion 50 mg / kg body weight, dermally. Group B was treated with 100mg of Malathion per kg B.W., dermally. Rabbits in group C were treated with Malathion at the rate of 200mg! kg B.W. Group D was treated with 400mg/kg B.W., dermally. The application of Malathion was repeated on Day 1, Day 3, Day 5 and Day 7 of the experiment. Group E was as control. Blood samples were collected from each animal separately before and after the experiment from their marginal ear veins. Serum was separated from the blood samples and was further analyzed for cholinesterase activity and lipid profile by spectro photometric method. Specified Randox kits were used for this purpose. Data collected from the experiment showed that Malathion inhibits the activity of cholinesterase enzyme. Also Malathion influences the lipid profile. In group A which was treated with Malathion 50mg/kg, the total cholesterol was increased up to 27.11%, high density lipoprotein (HDL) were increased up to 22.40%, low density lipoprotein were increased up to 175.44% and triglycerides (TGs) were decreased by 14.42%. In group B which was treated with Malathion 100mg/kg, total cholesterol was increased up to 34.46%, HDL increased up to 35.40%, LDL increased up to 183.09% while TGs were decreased by 14.02%. In group C which was treated with Malathion 200mg/kg, total cholesterol was increased up to 31.46%, HDL were increased up to
42.10%, LDL were increased up to 137.44% and TGs were decreased by 15.44%. While in group D which was treated with Malathion 400mg/kg, total cholesterol was increased up to 23.46%, HDL were increased up to 45.76%, LDL were increased up to 82.37% and TGs were decreased up to 14.95%.Activity of cholinesterase was decreased up to 82.74%, 91.59%, 89.63% and 86.64% in different groups like group A, B, C and D respectively. All the results were compared with the values of control group E. All the data obtained from these experiments was analyzed statistically.

Publisher: 2007Dissertation note: In present study a total of 100 serum samples from indigenous poultry and the dressers were analysed for determination of Toxoplasma specific anti-bodies. Under aseptic measures 1-2m1 of blood was withdrawn by veinpuncture and serum was separated. All the serum samples were analyzed for specific IgG anti Toxoplasma ant-bodies using Latex Agglutination Test (LAT). Positive reaction was visualized by the naked eyes or magnifying hand lens.
Commercially available Toxoplasma Latex test kit was used to determine the serum antibodies. Results were interpretated, data obtained was analyzed statistically by calculating the percent sero-positivity of Toxoplasma gondii in indigenous poultry.
Toxoplasma is one of the most common zoonosis worldwide.It is caused by toxoplasma gondii, an obligatory intracellular parasite that attacks warm blooded animals,birds including humanbiengs.Felines are the definite hosts where the parasite carries out its sexual cycle resulting in oocysts that are taken to the environment by the feces.Man birds and animals acquire the infection by ingesting oocysts that contaminate water,foodstuff, and pasture in that environment.
In the present study the overall seroprevalance of toxoplasma gondii infection in indigenous poultry and dressers are 12% respectively by using Latex agglutination test.
In indigenous poultry seroprevalance of toxoplasma gondii was 10% out of 100 hens examined, (3) were seropositive at screening dilution of 1:256 suggesting possible recent contact.
(2) were seropositive at 1:128 which was due to acquired or evolving immunity, while (1) were seropositive at screening dilution at 1:16 indicating residual or non specific immunity.
Toxoplasma gondii infection is increased with age because of constant exposure to contaminated environment and increased contact with cats.
In dressers (butchers) seroprevalance was 12% out of 50.Two were seropositive at screening dilution of 1:256 suggesting possible recent contacting.Two were seropositive at 1:128 which was due to acquired or evolving immunity,whike two were seropositve at screening dilution at 1:16 indicating residual or non specific immunity.
Due to increase prevalence of toxoplasmosis in humans,birds and animals daby day it is very necessary that public should be aware about the zoonotic importance of this disease and preventive measures to be adopted.

Detection Of Toxoplasma Gondii From Water And Matrices (Soil,Fruits &
by Adeela Ajmal | Prf.Dr. Azhar Maqbool | Dr. Kamran ashraf | Dr.Aftab ahmad | Faculty of Veterinary Sciences.
Material type: ; Format:

Publisher: 2010Dissertation note: Toxoplasmosis caused by Toxoplasma gondii is a widely distributed protozoan disease capable of infecting a variety of animal species. Felids, both domestic and wild, are capable of serving as definitive hosts, shedding T.gondii oocysts in their faeces.
People acquire toxoplasmosis posnatally by ingesting T.gondii oocysts from contaminated environments or by consuming T.gondii tissue cysts in inadequately meat products, raw meat containing tissue cysts or by ingestion of resistant oocysts from environmental matrices (soil, water, fruits and vegetables).
However, the impact of oocysts in toxoplasmosis epidemiology needs to be specified because they are suspected to be associated with T.gondii seroprevalence in some emerging outbreaks of acute toxoplasmosis in humans from soil or water. They are probably responsible for a significant part of infections in animals that could be later consumed by humans.
Detection of Toxoplasma gondii oocysts in environmental samples is great challenge as this coccidian parasite can be responsible for severe infections in humans and animals via ingestion of a single oocyst from contaminated water, soil, fruits or vegetables.
The present proposed study was designed to develop methods for the detection of oocysts
from Water, soil, food and parks environment.
The results of recovery test showed that it was possible to detect Tooplasma gondii parasite from water samples collected from various sources i e, drinking water from muncipility, lakes, pools, various reservoirs around farms and from tube wells. From the results ,The highest (13%) prevalence was reported from water around farms followed by lakes & pools (9%) then water reservoirs (7%) whereas the lowest from drinking water & tubewells i e 6 & 6 percent respectively.
A total of 250 samples of fruits and vegetables were collected for detection of T. gondii . From the results, it was noted that overall prevalence of T. gondii infection was higher in vegetables i e 5.6 % than fruits (4 %).
A total of 250 soil samples were collected from urban and rural areas. Of these 125 were from urban areas and 125 from rural areas. From the table-3 it was shown that the highest prevalence of T. gondii infection was noted in gardens and back yards of homes and gardens i e 20 & 20 % respectively. In these places cats often defecate and become a source of infection. Then followed by public enclosures where infection was 14.3%. The lowest i e 13.3% infection was noted at homes of urban areas.
T. gondii infection in rural areas indicated that It was highest (20% ) in home back yards followed by homes (16.7%) then public enclosure (14.5%) whereas the lowest (13.3%) at gardens of rural areas.

Publisher: 2010Dissertation note: Total of 72 three-week old chickens were divided into two groups, group A and group B. Thirty Six chickens were placed in group B, infected with H9N2 influenza virus; while 36 chickens were placed in group A, control group. Organ and blood samples were collected daily from day 2 post infection to day 10 post infection. The birds were offered toxin free feed and water ad-libitum.
The infected birds did not show any pathogenic symptoms of disease. Gross pathological lesions were mainly hemorrhages in trachea and lungs. Slight to severe enteritis from day 6-9 post infection along with congestion of caecal tonsils was also seen.
Main histopathological lesions involved tracheal deciliation, infiltration of monocytes and neutrophils as well as vascular congestion in form of hemorrhagic area, cellular infiltration of inflammatory cells was seen in lungs. Necrotic foci, accumulation of inflammatory cells, sloughing of mucosa and infiltration of leucocytes in caecal tonsils was observed.
Hematological parameters i.e. TLC, DLC, Hemoglobin were measured and analyzed. It was interesting to find out that significant increase was noted in TLC of group B and hemoglobin concentration between chickens of Group A and B was found; however when DLC was conducted, there was significant increase in blood heterophils and decrease in monocytes.
RT-PCR was conducted to detect viral RNA in organ samples and it was detected as early as 48 hours post-infection in organs samples collected from infected chickens. Moreover, we have detected viral RNA in organ samples until day 10 post-infection.

Eimeria tenella is the most common cause of caecal coccidiosis but E. necatrix is also isolated rarely. In the present study, 400 caecal samples suspected for coccidiosis were collected from two districts (Lahore and Gujranwala). Ten samples from twenty farms of each district were collected and examined for coccidiosis and species identication. Prevalence of coccidiosis was found 68%. It was more prevalent in district Gujranwala (71.5%) as compared to Lahore (64.5%). Eimeria species were identified by conventional (Direct Microscopy, Sedimentation technique, Floatation Technique and Sporulation) and molecular technique (PCR). Polymerase chain reaction was found the most sensitive ands accurate technique for species identification as compared to all conventional techniques. The prevalence percentage of E.tenella and E,necatrix was found 68% and 12.5% respectively. E.tenella was more prevalent in district Gujranwala (71.5%) as compared to district Lahore (64.5%). E.necatrix was also more prevalent in district Gujranwala (13.5%) than district Lahore (11.5%). The difference in percent prevalence of coccidiosis and species of Eimeria may be due to difference in farm management, farming type, biosecurity measures.

Publisher: 2011Dissertation note: The study was conducted to identify and compare the extent of gastrointestinal helminths in indigenous poultry and commercial layers. For this purpose, 200 gut samples (100 each from indigenous and commercial layers) were collected from different sources of Quetta district. All the material was brought to disease investigation lab, Quetta, for detailed postmortem and coprological examination.
The overall incidence of nematodes in indigenous chickens and commercial layers was 87% and 08% respectively. Three species of nematodes were recovered from both indigenous chickens and commercial layers. Ascaridia galli was the most common specie of nematodes recovered from small intestine while Heterakis gallinae and Subulura brumpti were isolated from the caeca of the sampled birds. The incidence of Ascaridia galli, Heterakis gallinae and Subulura brumpti was 75%, 25% and 16% in indigenous chickens and 06%, 04% and 03% in commercial layers respectively.
The overall incidence of cestodes was lower than those of the nematodes. It was found to be 78% in indigenous chickens and 05% in commercial layers respectively.
Five species of cestodes recorded from the gastrointestinal tract of indigenous chicken and were Raillietina tetragona (60%), Raillietina echinobothrida (21%), Raillietina cesticillus (14%), Cotugnia digonopora (29%) and Choanotaenia infundibulum (13%). On the other hand, following two species of cestodes were isolated from the gastrointestinal tract of commercial layers and included Raillietina tetragona (04%), and Choanotaenia infundibulum (02%).
Older birds have higher prevalence as compared with younger birds in indigenous and commercial layers. Slightly higher infection rates were recorded in females (51.7%) as compared with males (48.2%). On coprological examination, a greater proportion of birds were found infected with various helminthes and infection rate in indigenous birds was 66% as compared with commercial layers which was 3%.

Publisher: 2011Dissertation note: Mycotoxins are secondary metabolite toxins produced by fungi in or on grains, cereals and nuts used as feed in the poultry industry. Mycotoxicity in birds has been well documented and its severity increases in combination with other toxins. The study determined synergistic pathological responses in quail chicks when fed different level of Aflatoxin B1 (AFB1) and Ochratoxin A (OTA). A total of 245 quails chicks were divided into seven groups (G1-G7) having 35 quail chicks in each. OTA mixed feed was fed to quail chicks at a dose rate of 1 and 1.5 ppm in G1 and G2 respectively. G3 were fed 2 ppm OTA + 1 ppm AFB1. AFB1 was offered in the feed at a level of 1 and 1.5 ppm in G4 and G5 respectively. G6 birds were fed 2 ppm AFB1 + 1 ppm OTA while G7 acted as a control. All the birds offered toxin free basal diet for first 7 days. Day 7 was considered zero day of experiment. At this day chicks shifted to different groups of 35 each (G1-G7). Group G7 was control group and offered toxin free diet. Birds were monitored twice daily for clinical signs. Randomly selected six birds from each group were slaughtered at day 14, 21, and 28. Blood samples with and without anticoagulant were collected for hematological and biochemical studies respectively. Morbid tissue of liver, kidney, and intestine were collected for histopathological studies. The OTA groups developed anemia manifested by a significant decrease in the red blood cell count, packed cell volume percentage and hemoglobin concentration, while increase erythrocyte sedimentation rate at the end of the experiment all groups showed significant reduction in red blood cell count. This reduction was found to increase with time proportionally to the level of OTA and AFB1 alone or in combination exposure. Clinical signs in chicks administered AFB1 and OTA included depression, decreased feed intake and decreased body weight. Severity in clinical signs was dose related. Pathological lesions in liver of these chicks were hemorrhages, fatty change, centrilobular necrosis and periportal fibrosis. Microscopically, liver showed vacuolation, fatty change, congestion and individual cell necrosis. Kidney of these chicks included pyknotic changes in the epithelium of proximal and distal convoluted tubules. Severe necrotic changes in the collecting ducts and accumulation of pink homogenous material in the lumen of tubules. Intestine showed hemorrhages, edema, degeneration and infiltration of mononuclear cells were observed. OTA damaged intestinal mucosa more severely than AFB1. Serum biochemical study indicated a significant decrease in total serum proteins and increase in urea and creatinine. It is concluded that AFB1 and OTA are capable of inducing hematological and histopathological alterations in quail chicks at higher dietary concentrations, either individually or in combination.

Publisher: 2009-2011Dissertation note: This study was conducted by keeping in view the worldwide importance of Mycoplasma bovis to cause pneumonia and many other diseases, as it causes great economic losses to bovine industry. In the current project the incidence of Mycoplasma bovis to cause pleuropneumonia was studied, and its respective histopathological changes in lungs of the pneumonic adult buffaloes and buffalo calves were examined. 100 lung samples for this purpose (50 lung samples from adult buffaloes and 50 lung samples from buffalo calves) were collected from the Lahore Bakar Mandi Abbatoir. Samples were collected on the basis of following criteria: Red hepatization, grey hepatization, multifocal abscess, necrotic lung tissue. These samples were then divided into two portions, one half placed in 10% buffered formalin in the bottles and other half kept in sterile polythene bag. The portion of lungs for bacteriological study was kept in ice box. Histopathological procedure was performed in the pathology department of University Of Veterinary And Animal Sciences Lahore. The samples were subjected to histopathological procedures and then slides were observed microscopically for the changes. Microscopically pulmonary odema, consolidation, caseous necrosis, abscess infiltration of mononuclear cells, plasma cells, macrophages, neutrophils infiltration were observed. For culturing of Mycoplasma bovis PPLO broth was prepared and samples were inoculated in the broth medium. At 7th day of inoculation the yellow color of the broth medium appeared which was indicative of positive samples. 30% positive samples in adult buffaloes and 36% in buffalo calves were obtained. These samples were then inoculated on the PPLO agar plates for further precision of results. On agar plates typical colonies of the Mycoplasma were observed under bright field compound microscope and 60% positive samples in adult buffaloes and 66% in buffalo calves were obtained. Next step towards the confirmation of Mycoplasma bovis was specific acridine staining, in which positive of Mycoplasma bovis samples gave dull yellow to colorless appearance of yellow broth medium and gave egg fried colony on agar. 78% adult buffalo and 67% buffalo calves showed positive results. These samples were then subjected to final confirmatory test which was growth inhibition disk test, in which hyper immune sera was raised in rabbits and filter paper disks soaked in this sera were used to check the zone of inhibition on cultured agar plates. 70% positive samples in adult buffaloes and 75% in buffalo calves were obtained which confirmed the presence of Mycoplasma bovis. CFU/ml of the positive samples calculated between 105-108. So the incidence of Mycoplasma bovis to cause pneumonia in adult buffaloes and buffalo calves calculated was (10% and 12%) respectively.

evaluate the comparative efficacy of Sulfadimethoxine and Furazolidone and to study the effect
of Coccidiosis on blood parameters.
For this purpose, the faecal samples of three hundred dogs were examined in the Medicine laboratory, University of Veterinary and Animal Sciences, Lahore by direct smear method and concentration technique. Out of three hundred dogs, forty nine were found positive for coccidiosis, showing the prevalence of 16.33%. For the chemotherapeutical trials, forty five naturally infected and fifteen non-infected were selected and divided randomly into four groups having fifteen dogs in each group wise A, B, C and D. Group A was treated with Sulfadimethoxine at the dose rate of 60 mg/kg (orally). Group B was treated with Furazolidone at the dose rate of 20 mg/kg (orally). Group C was kept as infected non-medicated control. Group D was kept as non-medicated and non-infected control.
The faecal samples of experimental dogs were examined for OPG (oocyst per
gram) counts on zero day (pre-medication), 3rd day, th day, and 14th day medication and percentage reduction of oocysts was' calculated. Sulfadimethoxine showed 66.69%,90.89% and 98.29% efficacy and Furazolidone showed 63.95%,
88.78% and 96.64% efficacy on 3rd, th and 14th day, respectively.
Haematological study showed that the values of haemoglobin, packed cell
volume and total erythrocyte count were lower in groups A, Band C as compared to non-infected control group. The values of total leucocyte count were higher in group A, B and C' as compared to non-infected group. As a result of treatment in group A and B, the values of haemoglobin, packed cell volume and total erythrocyte gradually increased while that of total leucocyte count gradually decrease on day 3rd ,7111 and 14th post-medication. It has been observed during the present study that sulfadimethoxine and Furazolidone showed their effect on blood parameters as a result of coccidiosis.

Publisher: 2012Dissertation note: Trichomonas foetus (T. foetus) is a protozoan parasite of reproductive tract of large ruminants and causes abortion. This organism is found in males and females associated with varied pathology and clinical symptom. Disease has venereal transmission and male remain infected throughout the life. Pakistan is a developing country and artificial insemination facility is not available to all farmers and some are reluctant to avail it.
This study was designed to check the prevalence of T. foetus in large animals in district Hafizabad. One hundred and fifty preputial and vaginal samples were collected from cattle and buffaloes 75 each. These samples were from 100 females and 50 males. Vaginal mucus from females was thoroughly examined for T. foetus in direct smear and in smear stained by Giemsa stain. Male samples were subjected to examination by direct smear, centrifugation and stained smear performed from sediments for detection of T. foetus. Overall prevalence of T. foetus was 12.0% (18/150) in sampled animals and species wise T. foetus infection was 8% (6/75) for cattle and 16% (12/75) for buffalos. Sex related prevalence of T. foetus in cows is 6% (3/50) and in buffaloes was 14% (7/50). Infection was more common in buffalo bulls 20% (5/25) as compared with cow bulls 12% (3/25).
There was no difference in diagnosis of T. foetus in females by direct smear or by examination of stained smears. Whereas stained smears prepared from sediments of preputial washings were more sensitive in diagnosing of T. foetus infection as compared with direct smear method. Study also indicated that infection was exclusively seen in animals that were involved in natural breeding.

Secondly to evaluate the efficacy of composted poultry litter/dead birds in broiler quail ration. The experiment was conducted at Poultry Research and Training Centre and Avian Research and Training Center, UVAS, Lahore in two different phases. The first phase was of 8 weeks duration in which composting of dead birds was doneusing advance windrow pile technique and proximate analysis of the composted material wascarried out. During the second phase, a quail ration was formulated according to dietary recommendations of NRC (1994) with inclusion of 0, 2, 4 and 6% compost and fed to quails,For this purpose, a total of 1200 day old Japanese broiler quails were randomly divided into 4 different experimental groups (A, B, C, and D). Group A was control and group B, C, and D contained 2, 4, and 6% composted ration respectively. The birds in each group were replicated six timescomprising 50 birds in each replicate. After 4 weeks of age three birds per replicate were slaughtered and their slaughtering parameters were recorded. The data thus obtained were analyzed through ANOVA in completely randomized design (Steelet al.1997) and means were compared by Duncan's Multiple Range (DMR) test (Duncan, 1955) using SAS (Statistical Analysis System) version 9.1. In production performance feed intake, body weight, body weight gain and FCR showed positive response when fed different levels of composted diet while mortality % remained unaffected throughout the experimental period. In slaughtering parameters live body weight (g), carcass weight %, dressing Weight %, Giblet weight %, Gizzard weight % and Heart weight % showed positively when fed different levels of composted diet while liver weight % remained unaffected throughout the experimental period.

However, there is a paucity of information regarding the prevalence of various parasites in local fish especially fishes of fresh water. Therefore, the present study has been planned to investigate the prevalence of various parasites of the gastrointestinal tract and liver of Wallago attu(Malee) ,Rita rita (Khaga), Channa marulius(Saul) and Mystus seenghala(Seenghari). Therefore, it was hypothesized that there is a variation in the occurrence of various endoparasites in various species of fish.
A total fifty gut samples from each of breed of fish (Wallago attu (Malee),Rita rita (Khaga), Channa marulius(Saul) and Mystus seenghala(Seenghari) were collected from various fish markets located in Lahore City like Bhatti Gate, Samnabad, Tollinton Market, and were analyzed to determine the prevalence of various endoparasites in the intestine. The gut samples were collected in 0.9% physiological saline and were preserved in 4% formalin. The recovered parasites were fixed and identified on the basis of morphology to calculate the prevalence rate. The data thus collected was analyzed using a Pearson's chi-square. Results showed that out of 65 fish samples collected from Tollinton market that included Rita rita (n = 20), Wallago attu (n = 15), Channa marulius (n = 15) and Mystus seenghala (n = 15), 7 (10.76%) samples of gut harbored various parasites. Similarly, the prevalence rate of parasites in two other localities were 17.39% in Bhatti-gate fish market and 18.18% in Samanabad Fish market. The overall prevalence rate was found to be 15.5%. There was no statistical difference in the prevalence rate when data was assorted on the basis of localities. Both single and mixed infections were noted in fishes collected from all three localities and all four species of fresh water fish. The various parasites revocered from the intestines of the gut from all species included P. heteropneustus Cucullanus sp., Cucullanus sp., Phyllodistomum sp. and R. magna.

Publisher: 2012Dissertation note: The main area of research in this study was to assess the prevalence, hematological and serological aspects of ovine nematodiasis. Four main experiments were conducted to highlight the objectives of the present research study.
First experiment was conducted to find out the prevalence of sheep major nematodes for one year (January-December 2011). For this purpose three sheep breeds i.e., Balochi, Babrik and Harnai (either sex and between 1-5 years age groups)were selected randomly from three sites i.e., Quetta, Ziarat and Loralai. Faecal analyses of these sheep showed overall higher (40.25%) nematodes prevalence at Loralai followed by Ziarat (29%) and Quetta (23.92%). Five nematodes infection were recorded at three experimental sites. Among these, H. contortus (5.58 to 10.42%)and was the higher prevalent followed by N. battus (6.92 to 9.33%), S. papillosus (4.42 to 9%), T. colubriformis (2.33 to 7.33%) and T. ovis (1.83 to 6.83%).The nematodes prevalence was higher in one and five years old sheep. The female-sheep were infected with higher nematode prevalence higher the than male once and sometimes non-significant difference. These five nematodes were prevalent almost throughout the year; however, a peak infection was recorded during August/September. The high temperature, rainfall and humidity during these months may be predisposing factor of higher prevalence.
Second experiment was on diagnosis of sheep nematodiasis through Enzyme-linked immunosorbent assay (ELISA). For this purpose H. contortus and T. ovis positive samples (200) based on coprological examination were also indicated 100% positive sensitivity by the ELISA based on crude somatic antigen, while on excretory antigen based showed lower (92%) sensitivity. The sera (n=200) of non-infected sheep (based on coprological examination) showed marked difference results. Such as 168 (84%) and 166 (83%) samples were found positive with H. contortus and T. ovis, respectively. While, based on crude somatic antigen 158 (79%) and 144 (72%) samples were found positive with H. contortus and T. ovis, respectively.
Third experiment was conducted to determine the hematological values and total serum protein indices in healthy and nematodes infected sheep. The statistically significant (P<0.05) difference in PCV, Hb, RBC, WBC, Eosinophil, ESR and Total serum protein values was observed among healthy and nematode infected sheep groups. While, there was no statistically significant (P<0.05) difference in TLC, Lymphocytes, Neutrophil, Monocytes and Basophils counts in healthy and nematodes infected sheep groups.
Fourth experiment was conducted on assessing the comparative efficacy of synthetic (Oxfendazole and Ivermectin) and locally manufactured herbal medicine (Deedani, Kirmar and Atreefal Deedan) anthelmintics against sheep nematodes at AZRC/PARC Range-livestock Research Station Sanjavi district Ziarat. The present study results regarding the comparative efficacy showed that, Atreefal deedan among herbal products (Deedani and Kirmar) and Ivermectin than Oxfendazole was found effective against sheep nematodes. The sheep treated with Ivermectin showed highest (96%) FEC reduction, followed by Oxfendazole/Atreefal deedan (86%), Kirmar (60%) and Deedani (32%).

Publisher: 2014Dissertation note: Vector-borne diseases are among the major causes of illness, death and economic losses particularly in tropical and subtropical areas of the world. Mosquitoes are most important single group of insects, transmitting wide range of human diseases like malaria, Japanese encephalitis, dengue fever, yellow fever, filariasis and several other infectious diseases. Malaria is a major global public health problem. Several Anopheline species are prevalent in Pakistan among which Anopheles stephensi and Anopheles culicifacies are confirmed vector of Plasmodium. An. subpictus is a confirmed secondary vector of malaria in many countries. A wide range of this species is also distributed in Pakistan. The aim of the present study was to determine the vectorial role of An. subpictus in the transmission of malaria in Pakistan through microscopy and polymerase chain reaction (PCR).
After species identification, the mosquitoes were examined microscopically and were found negative for the presence of human Plasmodium sporozoites. The DNA extracted from An. subpictus was subjected to PCR but no Plasmodium specific amplification was observed. Keeping in view the sample size, it was concluded that further study is required with even large sample size before declaring that An. subpictus is not a vector of Plasmodium in Pakistan.

Publisher: 2013Dissertation note: Mosquito are major vectors, considering the havoc they play by transmitting many diseases which have greatly affected human beings worldwide. The ecological, socioeconomic conditions of different regions and the emergence of insecticide resistance in main vectors are strongly responsible for determining the geographical distributions and incidence of vector-borne diseases. Among mosquitoes, Anopheles species are responsible for transmission of filariasis, Japanese encephalitis virus and malaria in subtropical region. An. subpictus is a confirmed vector in many countries of South and Southeast Asia. The present study was designed due to limited earlier records regarding insecticide susceptibility status of An. subpictus from district Kasur, Punjab. During the first half of the study, three insecticides i.e. DDT 4%, deltamethrin 0.05% and permethrin 0.75% were testing by using WHO susceptibility bioassay. A total approximately (n=1000) different types of mosquitoes were caught from district Kasur. Mosquitoes belonging to three genra Anopheles, Culex and Aedes were found in our collection. After species identification, An. subpictus was separated for further processing. It was highly abundant species among Anophelines species captured. Field collected adult blood fed females of An. subpictus was reared in the insectary for F1 generation. Two to three days old non engorged adults of An. subpictus were evaluated by using WHO susceptibility bioassays. Both male and female mosquitoes have shown resistance against all three insecticides tested. Probit analysis was used to check the time-response values. Percentage mortalities were recorded against DDT, deltamethrin and permethrin (mortality range 29.47 %-76.28 %.) with higher KT50 and KT95 values.Second half of the study was undertaken to quantify detoxifying enzymes in An. subpictus following WHO biochmical assays. Biochemical analysis of detoxifying enzymes in An. subpictus has revealed that there is significant alteration/elevation of metabolic enzymes when compared with the lab strain might be a contributing factor in conferring insecticides resistance. Elevated levels of GST (0.469 ± 0.115), MFOs (11.665 ± 4.165), ? esterases (1.5808 ± 0.7657) and ? esterase (3.9682 ± 2.311) were detected in An. subpictus. There was a significant high alteration of AChE enzyme activity detected in this species with 57.52% (± 9.234) mean percentage propoxur inhibition. These enzymes are implicated in the metabolism of DDT, pyrethroids and carbamate insecticides.
