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.

   doi: 10.14202/vetworld.2014.970-975




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.

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.

Research (Published online: 13-11-2014)
8Assessment of innate immunity by phagocytic activity in non-descript and Sahiwal cattle in Chhattisgarh - Govina Dewangan, S. D. Hirpurkar, Devesh Kumar Giri and Deepak Kumar Kashyap
Veterinary World, 7(10): 943-947



   doi: 10.14202/vetworld.2014.943-947




Aim: The objective of the research was to assess the innate immunity status of non-descript (ND) cattle in comparison to Sahiwal cattle in Chattisgarh by the determination of the phagocytosis activity (PA) and opsonocytophagic index (OI).
Materials and Methods: In-vitro phagocytic activity of neutrophil was studied in ND and Sahiwal (S) cattle after dividing them in groupsviz. ND-I, ND-II, S-I and S-II. Neutrophils were separated from the blood and activated with Staphylococcus aureus. PA and OI were observed under high power of a microscope at ×1000  magnification.
Results: PA (percent) in groups ND-I, ND-II, S-I and S-II was 73.00±1.03, 82.25±1.51, 80.75±1.36 and 82.37±1.27, respectively which vary significantly (p<0.01), with respect to age. The observations regarding the OI (bacteria per neutrophil) in groups ND-I, ND-II, S-I and S-II was 7.17±0.04, 7.76±0.09, 7.02±0.04 and 7.79±0.06, respectively. Age difference was evident, i.e., OI increases as age increases.
Conclusion: Innate immunity plays a vital role in host defense against diseases. Neutrophil kills the invading pathogen by phagocytic action. PA and OI is an important tool for the assessing innate immune status. After coincubation of neutrophil with bacterial cells, PA was significantly lower (p<0.01) in ND-I, calves group then other groups. Further, the result of OI clearly indicates that OI has increased as age increases in both breeds. The study will, therefore, generate first hand information on ND cattle along with their relative statistical differences, if any, when compared with Sahiwal.
