Publisher: 2016Dissertation note: The present study was conducted to investigate the prevalence of Ovine and Caprine Theileriosis in Northern Highlands and Suleiman Mountain Region of Balochistan, Six thickly populated /union councils were included in the study area. Samples were collected from 2870 animals Sheep (n= 2200) and Goats (n= 670) for screening of the disease. The samples were collected and processed in Regional Disease Investigation Laboratories, Department of Livestock and Dairy Development Balochistan, T.B. Sanatorium Hospital Quetta and Center for Vaccinology, Bacteriology, The University of Balochistan, Quetta and Medicine Laboratory, Department of Clinical Medicine and Surgery, The University of Veterinary and Animal Sciences, Lahore. Data revealed 20.82% disease in sheep and 9.70%. in goats. The regional prevalence of theileriosis revealed 19.19% in Northern Highlands and 17.48% in Suleiman Mountain Region Chi-square analysis showed significant difference in the prevalence of disease in sheep and goats. The regional difference was not significantly different between two regions of Northern Balochistan. The comparison among union councils showed significant difference being highest prevalence (22.71%) in union council Kuchlak district Quetta followed by Aghberg (18.42%) and Hanna Urak (15.53%) in Northern highlands and Union Council Zangiwal Jogezai (19.83%) followed by Kach Amaqzai (16.30%) and Sinjavi (15.92%) in SMR. The disease prevalence when compared among 4 different breeds of sheep showed significant difference being highest in Karakul breed (34.62%) followed by Shinwari (24.54%), Bibrik (19.36%) and Harnai (16.40%). The highest prevalence of theileriosis in sheep and goats were observed in Summer season (30.30%) followed by Autumn 19.07%, Spring 14.52% and Winter

7.61%. Chi-square analysis of the data showed significant difference in the prevalence of the disease in different seasons of the year. The disease was also compared in three age groups of sheep and goats. The data showed 22.17% disease in adult animal group above 2 years of age followed by 15.85% in animals between 1-2 year and 7.99% in age group below one year. Statistically significant difference in all age groups was found in chi-square analysis. The sex wise prevalence of theileriosis revealed non-significant difference between male and female sheep and goats. Two different species of Theileria were reported by many researchers causing disease in sheep and goats. The PCR was carried out for the identification of Theileria species affecting sheep and goats in Balochistan. Two species specific sets of primers were designed using 18SRNA gene sequence to identify these two species of Theileria and the distribution among the two species of animals. The genomic DNA of two species of parasite was successfully amplified in positive samples. The assay was proved successful and we recommend for the prevalence surveys for theileriosis in sheep and goats. The data showed that the prevalence of T. lestoquardi was 73.80% in sheep and 69.23% was in goats in the target regions. It was found the T. lestoquardi was highly prevalent and causing theileriosis in small ruminants. The prevalence of T. ovis was 26.19% in sheep and 30.76% in goats respectively in the investigated animals; it was less than T. lestoquardi. It was concluded that both Theileria species were identified and found circulating in small ruminants in the target region of Balochistan. In the study we determined that PCR method based on 18S RNA gene could detect and differentiate T. ovis and T. lestoquardi.
Effect of theileriosis in sheep and goats on hemeto-biochemical parameters were studied included RBCs, Hb%, PCV, Platelets, WBCs, MCV, MCHC, AST, ALT, BUN, Bilirubin and Creatinine. Blood samples were collected from Theileria confirmed, diseased animals (sheep and

goats) along with equal number of healthy animals for comparison. In sheep RBCs, Hb%, PCV, WBCs, MCHC, AST, ALT and Creatinine values showed significant difference when compared with values of healthy animals. Significant (p<0.05) reduction was noted in measurement of RBCs, Hb%, PCV and MCHC whereas, AST, ALT and Creatinine showed significant increase in diseased animals. In goats affected with theileriosis showed significant decrease in RBCs count and Hb%. The values for AST, ALT and Creatinine were found significantly increased in diseased animals when compared with healthy control group of equal number of animals. In present study it was noted that Butalex intra muscularly at the rate of 2.5 mg/kg body weight is quite effective in eliminating the Theileria parasite from the blood of sheep and goats and treatment at the day 10 post treatment. Imizol was also found an effective treatment of theileriosis but less effective than Butalex. Availability: Items available for loan: UVAS Library [Call number: 2690-T] (1).

Publisher: 2015Dissertation note: Ophthalmic procedures can be performed by many clinicians in horses using local nerve blocks by using local anaesthetics for short duration of action for completion of these procedures. These surgical procedures may involve exclusion of third eyelid, suturing of laceration around eye orbit and tumor which can be caused due to any reason with in time period of thirty minutes. Inner chamber centesis can be done easily by using the above mentioned technique in standing horse.
There are numerous benefits of doing standing surgical methods and avoiding general anaesthesia in horses. As hospitalizing horse may get other infectious diseases from surroundings like colitis and laminitis and also injured it when recovering from general anaesthesia. On the other hand standing surgical procedure reduced such complication by using local anaesthetic for short duration.
Bupivacaine Hcl gave an ideal local eye anaesthesia compare to xylocaine Hcl for standing surgical procedures in horses.
The present study was accomplished to assess the effectiveness of two local eye anaesthetics; xylocaine Hcl and bupivacaine Hcl by two different techniques i.e. retrobulbar technique and auriculopalpebral technique in horses. A total of 12 horses from indoor clinic and S.P.C.A were used in this study. These horses were subjected to two groups’ i.e. Group A and B. Each of these groups was further subdivided into two subgroups i.e. Group AI, AII and BI, BII respectively.
SUMMARY
42
Horses in group A were administered xylocaine Hcl through auriculopalpebral technique and retrobulbar technique. While horses of subgroup AI were given xylocaine Hcl by auriculopalpebral technique and horses in subgroup AII were injected xylocaine Hcl by retrobulbar technique.
Likewise horses in subgroup BI were given bupivacaine Hcl by auriculopalpebral technique, while those of subgroup BII were given bupivacaine Hcl through retrobulbar technique. The efficacy of above mentioned local anaesthetics was compared on the basis of Pattern of induction, Duration of anaesthesia and Recovery Pattern. Presence or absence of reflexes was also noted i.e. Pupillary Light Reflex and Blink reflex.
The data were analyzed through one way analysis of variance (ANOVA). The difference in group’s means was determined by Least Significant Difference (LSD) post-hoc test. A probability level of (P<0.05) was considered as statistically significantly difference. The statistical analysis was performed using statistical package for social science (SPSS) version16.

Publisher: 2015Dissertation note: Mouflon sheep have lovely brown colored short haired coat. Typically it is not the wild animal found in Pakistan but a little population of Mouflon sheep is present in Pakistan in the captive vicinities like private zoo and wild life parks .Their population is countable, 150-200 Mouflon sheep are present. They can be parasitized by many nematodes, one of the most important is Haemonchuscontortus. Adult Haemonchuscontortus found in the abomasum of the animal.Female parasite can lay up to 1500 eggs in a day in mid-Summer July- August and those eggs produce the infective stage L3, which after infestation causes heavy blood loss resulting anemia, weight loss, emaciation and sudden death in acute cases compromising the production and propagation losses in Mouflon sheep.
The Mouflon sheep of various private and public Zoo and Wild Life Parks located in area of District Lahore were included in this study. A total of 100 Mouflon sheep were examined coprologically for the presence of Haemonchuscontortus for the present study. It is difficult to restrain the wild animal, a Dort was used for this purpose keeping in view of this problem about 3 gram of sample were collected early in the morning from the freshly passed feces, for this purpose disposable gloves was used on hands,the samples were collected carefully to avoid soil contamination the sample was placed in self-sealing polythene bags and were transferred to the laboratory in ice pack cooler. The samples were stored in refrigerator at 4°C till analysis.
The fecal samples were analyzed for Haemonchuscontortus eggs using direct smear method and floatation technique, while the egg count were performed by McMaster technique at medicine Laboratory University of Veterinary Animal Sciences Lahore the identification of Haemonchuscontortus was made by using standard procedures. Infection rate was calculated by using formula
Infection rate (%) = No. of infected animals (n)/ total No. of sampled animals (N) × 100
The infection rates were calculated in this study and total Thirty (33) animals were found positive after qualitative and quantitative analysis of fecal samples. The infection rate of Haemonchuscontortus in Mouflon sheep were calculated out of sampled animals which resulted the significant (P < 0.05) infection rate in females as well as in male Mouflon sheep. The infection rate in female Mouflon sheep was 33.82 % and in males it was 31.25 % in males out of positive animals. Similarly The infection rate of H. contortus in Lahore Zoo, Safari Park Lahore and Jallo Park was 29.72, 32.50, 39.13 respectively, and the infection rate of H. contortus in age group of 1-3, 4-6, 7-9 was 39.58, 27.27, 26.31 respectively.
For therapeutic trails, a total of 30 animals positive for nematodes having egg per gram between 1000---2000 were divided into 3 groups A, B, and C each group were comprised of 10 animals. The animal of group A was treated with Albendazole at the dose rate of 10 mg per kg of body weight PO; group B was treated with Levamisole at the rate of 7.5 mg per kg of body weight PO whereas the group C was treated with Pyrentelpamoate at the dose rate of 25 gram PO.The fecal sample of all groups were collected at day 0 (pre-treatment) and then at 3rd day 5th, 7th and 12th (post-treatment). The efficacies of these drugs were assessed on the bases of reduction in egg per gram and calculated as per formula of (Iqbal at al. 2013).
Drug efficacy = {(pre-treatment EPG - post-treatment EPG / pre - treatment EPG)} × 100
The chemotherapy of Haemonchuscontortusin Mouflon Sheep were studied in different 3 treatment groups. Microscopically screened out Haemonchuscontortus positive Mouflon sheep were divided in Three (3) treatment groups T 1, T 2 and T 3 and each group contained Ten (10) positive animals. Faecal samples of animals were examined at day 0 pre-treatment and at days 3, 5, 7 and 12 post treatment. All the treatment groups showed a significant reduction (P < 0.05) in eggs per gram (EPG) at 3rd, 5th, 7th and 12th days after treatment. The maximum reduction in EPG %age was 96.1 % showed by T 1 group treated with single dose of Albendazole at 10 mg/kg body weight at day 7 post treatment while the groups T 2 and T 3 showed maximum reduction of 95.52 % and 93.26 % at day 12th post treatment. Hence Albendazole was the best group found against Haemonchuscontortus at day 7 post treatment among the other two groups of drug used.
Data on Infection rate of Haemonchuscontortus was estimated by Pearson’s chi-square test. For significance whereas data on chemotherapy was analyzed by one way analysis of variance (ANOVA) using SPSS, P< 0.05 were considered significant.
