Therapeutic and anti-inflammatory potential of aqueous extract of Phyllanthus emblica (Common name - Amla) was evaluated in mastitic cows. The milk Somatic Cell Count (SCC) and ceruloplasmin concentration was significantly (P0.05) higher in mastitic cows prior to treatment. The parameters of mastitic cows treated with P. emblica (group III) and with amoxicillin sulbactum combination (group IV) were compared to that of healthy cows (group I and II). Significant reduction (P0.05) in Somatic Cell Count (SCC) was observed in both the treated groups. The level of ceruloplasmin significantly (P0.05) reduced in group III and IV after treatment. Results of the present experiment indicate reduction of SCC and ceruloplasmin level in the mastitic animals treated with the P.emblica extract. The extract of P. emblica significantly reduced (P0.05) the udder inflammation and helped in lowering the concentration of inflammatory marker ceruloplasmin. Therefore P. emblica extract could be advised for the treatment of bovine mastitis.

Recombinant LipL32 and LipL41 outer membrane proteins of Leptospira interrogans serovar Canicola were produced, and used as a pooled antigen in enzyme-linked immunosorbent assay (ELISA) to detect leptospiral antibodies in bovine sera samples. The optimum concentration of the pooled antigen was found to be 50ng of each antigen per well by using known positive and negative cattle sera. Using a total of 500 bovine sera samples the sensitivity, specificity and accuracy of pooled antigen based ELISA as compared to microscopic agglutination test (MAT) were 100%, 88.1% and 91.6%, respectively. The results suggested that antigen in ELISA could be preferred for detection of all those cases, which might have remained undiagnosed by performing MAT.

Therapeutic and anti-oxidant potential of vitamin E and selenium was evaluated in mastitic cows. The CMT point score and milk somatic cell count (SCC) was significantly (P0.05) higher in mastitic cows prior to treatment. Reduced activity of enzymatic anti-oxidant catalase was observed in mastitic animals. The parameters studied in mastitic cows treated amoxicillin sulbactum (group II) and with amoxicillin sulbactum, vitamin E and selenium (group III) were compared with that of group I healthy cows. Significant reduction (P0.05) in CMT and SCC was observed in both the treated groups. However, reduction in CMT point score and SCC was more pronounced in group III than group II cows. Synergistic action of antibiotic and vitamin E selenium significantly (P0.05) enhanced the activity of catalase in group III mastitic animals on day 8 time period. Therefore, vitamin E and selenium supplementation could be advised in the therapy of mastitis.
