A study was conducted to investigate changes in various biochemical parameters during mastitis. For this blood samples were collected from 20 cows suffering from mastitis and 20 normal cows. The Vet test chemistry analyzer (Idexx laboratories) was used for the estimation of biochemical parameters from blood serum of these samples i.e., calcium, glucose, Serum albumin, Serum globulin, Total protein, creatinine, blood urea nitrogen, SGPT).The data generated from these investigation were analyzed by student t-test and p-value was calculated and p-value less than 0.05 considered as significant. The level of glucose was found to be (25.06±6.34)mg/dl in mastitis cow and (58.96±7.85) mg/dl, in healthy one. The value for glucose in mastitis cow is significantly lower than the normal. It may be due to decrease in food consumption thus leading to hypoglycemia. Studies in cows with mastitis have shown the level of calcium (8.72±0.85) mg/dl which was significantly lower than that (10±0.59) mg/dl in the healthy ones. Albumin (3.49±0.28)g/dl were found to be lower in the mastitis cows as compared to (3.98±0.3)g/dl the healthy ones. In sufficient nutrition is found to possibly lower the albumin synthesis. The level of serum calcium is said to lessen as the level of serum albumin is low. Whereas, level of blood urea nitrogen (23.25±5.12) mg/dl was significantly high in mastitis cow than control (16.35±3.96) mg/dl. The values for creatinine (1.46±0.26) mg/dl were significantly higher in mastitis cow as compared to control group (1.18±0.21) mg/dl. This increase is thought to be due to severe necrosis in the udder tissue, which possesses very rich smooth muscle. The value for SGPT (78.92±5.98) mg/dl in mastitis cow was found to be significantly higher than the control (38.5±4.94) mg/dl. Values for total serum protein and serum globulin were non significant but higher in mastitis cows. Therefore, it was concluded that biochemical parameters were changed in mastitis. The main detrimental production effect induced by mastitis is a more or less persistent decrease in milk yield.
