Aim: A captive male jaguar (Panthera onca) was anaesthetized for surgical excision of a tumor at the left belly fold under xylazine-ketamine immobilization and propofol anesthesia. The objective was to assess the dose of xylazine and ketamine required to abolish ear flick reflex for safe approach when the jaguar was under chemical immobilization and efficacy of propofol induced anesthesia.

Materials and Methods: A male jaguar (P. onca) aged 14 years and weighing approximately 90 kg was subjected to chemical immobilization using a combination of xylazine and ketamine using a blow pipe. The jaguar was approached after the absence of ear flick reflex and transported to zoo Operation Theater. Propofol was administered intravenously to induce and maintain anesthesia. The tumor was excised using thermocautery and subjected to histopathology.

Results: Ear flick reflex was stimulated at 5 and 10 min after immobilization and observed shaking of head and movement of fore limb following administration of xylazine and ketamine. Dose of xylazine and ketamine required for chemical immobilization, characterized by absence of ear flick reflex was 1.0 and 3.5 mg/kg body weight respectively, and was achieved in 13 min. The surgical plane of anesthesia was maintained for 11 min following administration of propofol at a dose of 2 mg/kg body weight intravenously. The jaguar recovered in 41 min following surgery. The excised tumor was confirmed as sebaceous adenoma on histopathological examination. The animal recovered uneventfully, and no recurrence of the tumor was noticed in 3 months follow-up period.

Conclusion: The total dose xylazine and ketamine required for chemical immobilization with absence of ear flick reflex was 1.0 and 3.5 mg/kg body weight respectively. Further, administration of propofol intravenously, at a dose of 2 mg/kg maintained anesthesia for 11 min. Histopathological examination of the excised tumor at the belly fold was confirmed as sebaceous adenoma.

Aim: To determine the etiology of clinical mastitis in Murrah buffaloes and to develop an antibiogram of organisms isolated.

Materials and Methods: A total of 564 quarter milk samples of 144 buffaloes suffering from clinical mastitis received in Veterinary College Central Laboratory were inoculated on blood agar, MacConkey’s lactose agar and sabouraud dextrose agar. Bacteria isolated were characterized to the species level and subjected to in-vitro antimicrobial sensitivity testing.

Results: Out of 564 quarters examined for mastitis, 320 (56.73%) quarters were found culturally positive showing isolation ofStaphylococcus aureus 140 (38.04%), Streptococcus dysgalactiae 112 (30.43%), Streptococcus agalactiae 13 (3.53%), Escherichia coli 74 (20.10%) and Corynebacterium pyogenes 29 (7.88%). On carrying antibiogram staphylococci and streptococci revealed high sensitivity towards chloramphenicol, gentamicin, amikacin and enrofloxacin. Streptococci showed high sensitivity towards ceftriaxone and cefaperazone also. E. coli was found highly sensitive to chloramphenicol and gentamicin. C. pyogenes was sensitive to the majority of antibiotics.

Conclusion: S. aureus was the most predominant bacteria isolated from mastitis cases and irrespective of the isolates chloramphenicol was found to be most sensitive when tested in-vitro.

Aim: Estimation of some biochemical constituents in follicular fluid of non-descript cows of Assam.

Materials and Methods: Twenty five pairs of ovaries were collected from local slaughter house and the follicular fluid was aspirated from small (2-4 mm), medium (4-6 mm) and large (6-9 mm) follicles. Aspirated fluid samples were centrifuged at 4000 rpm for 20 min in a refrigerated centrifuge to remove granulosa cells and other cell debris. Supernatant was used for estimation of glucose, total protein, cholesterol, acid phosphatase and alkaline phosphatase. Data generated in the study were analyzed statiscally by SPSS (version 16.0). SPSS South Asia Pvt. Limited, Kacharakanahalli, Bangalore, 560043).

Results: A non significant difference was recorded in case of total protein and cholesterol of follicular fluid of small, medium and large sized follicles of cow. However, the glucose level significantly (p<0.01) increased with the increase of follicular size where as the activity of acid phosphatase and alkaline phosphatase significantly (p<0.01) decreased with increase of size.

Conclusion: Certain biochemical constituents and enzyme activities of follicular fluid changes with the growth of follicles in non-descript cows of Assam. The glucose concentration increased with the growth of the follicles while acid phosphatase and alkaline phosphatase levels had an inverse relation with the size of the ovarian follicles.

Aim: The present study was carried out to evaluate the nutrient digestibility of sweet sorghum stover, an unconventional roughage source in ram lambs in comparison to conventional sorghum and maize stovers.

Materials and Methods: 18 Nellore ram lambs aged about 3 months (average body weight 15.65±0.10 kg) were randomly allotted to three complete rations formulated with roughage to concentrate ratio of 60:40 using sorghum stover (D1), maize stover (D2) and sweet sorghum stover (D3) as roughage source for a period of 120 days. At the end of the growth trial, a metabolism trial was conducted to evaluate the nutrient utilization of the complete diets.

Results: There was no significant difference in nutrient digestibility of dry matter, organic matter, crude protein (CP), crude fibre, ether extract and nitrogen free extract in ram lambs fed D1, D2 and D3 diets, respectively. The digestibilities of acid detergent fibre and neutral detergent fibre did not differ significantly among the ram lambs fed various experimental diets. All the lambs were on positive nitrogen balance. Nitrogen balance was comparable among the various groups. The digestible CP and total digestible nutrients, digestible energy and metabolisable energy content of D1, D2 and D3 diets did not show any significant difference.

Conclusion: It can be concluded that, sweet sorghum stover can be incorporated in the complete diets of sheep at 60% level by replacing conventional roughages such as sorghum stover and maize stover, processed as mash form without affecting the voluntary intake and digestibility of nutrients.

Aim: This study was conducted to evaluate the concentrations of sodium (Na+) and potassium (K+) ions in milk of lactating dairy cows with and without subclinical mastitis as putative indicators for detecting subclinical mastitis in dairy cows.

Materials and Methods: Thirty seven lactating dairy cows were screened for the evidence of subclinical mastitis using California mastitis test (CMT). The lactating dairy cows were categorized as CMT-Positive (CMT-P; n=20) and CMT-Negative (CMT-N; n=17) based on whether they were positive or negative for CMT using a standard kit. The CMT-P lactating dairy cows were further sub divided into subclinical 1+ (S1+; n=6), subclinical 2+ (S2+; n=9), and subclinical 3+(S3+; n=5). Direct microscopy somatic cell count (SCC) was used to determine the SCC using Wright’s stain. The samples were filtered and diluted at 1:100 dilutions before being measured for the concentrations of Na+ and K+ using atomic absorption spectrophotometer.

Results: There was a significant increase (p<0.05) in SCCs and Na+ concentration in the milk of CMT-P dairy cows, with a mean Log10 SCC score of 5.35±0.06 cells/ml and mean Na+ concentration of 232±19.1 mg/dL. However, there was a significant reduction (p<0.05) in the concentration of K+ (123±7.6 mg/dL) in the milk samples of the CMT-P cows. There were significant differences (p<0.05) in SCC, Na+ and K+ concentrations between milk samples from the CMT-N dairy cows and CMT-P subgroups; S1+, S2+, and S3+ respectively. Potassium (K+) concentration had a significant strong negative correlation with sodium (Na+) concentration (r=−0.688; p<0.01) and weak positive correlation with SCC (r=−0.436; p<0.01). The sensitivity of using Na+ and K+ concentrations as detection indices for sub-clinical mastitis is 40% and 90%, respectively, while the specificity of each was 100%.

Conclusion: This study thus shows that evaluation of Na+ and K+ concentrations from milk samples of dairy cows with sub clinical mastitis can be of immense diagnostic benefit and will compliments detection using CMT alone.

Keywords: potassium ion, sodium ion, somatic cell count, subclinical mastitis.

Abstract

Diabetes has evidence in ancient literatures, though recently is being considered as one amongst the most emerging disease condition in both human and companion animals. Diabetes mellitus is one of the common endocrinopathy of dog characterized by hyperglycemia, glycosuria and weight loss. Reports suggests high fraction of canine population suffer with diabetes world over. Studies in different veterinary hospitals of United States suggest increase in cases of canine diabetes and decrease in case fatality rate over time. Increase in cases of canine diabetes worldwide is attributed to awareness amongst pet owners, better veterinary health facilities, breed preferences by dog owners, increase dependence on commercial feeds, obesity, etc. Diabetes in most dogs is immune mediated and insulin dependent. Breed predisposition in canine is attributed to dog leukocyte antigen gene pool encoding form major histocompatibility complex-II molecules, however research is still underway. Diagnosis of diabetes still relies on blood sugar evaluation for screening of canine population, though many other diagnostic methods have shown promising benefits including measurement of fructosamine and glycated haemoglobin. Management of diabetes in dog is based on insulin therapy, diet modification and exercise. Use of oral anti-diabetics drugs in canine is limited though experimental studies have shown promising results. Alternative therapies have been explored, but only a few approaches have shown promise for clinical application.
