Levels of Blood Biochemicals of Repeat Breeder Cows in Field Conditions

Certain biochemical constituents in blood serum during the estrus period are associated with the fertility status of cows and their reproductive behavior. This study was carried out in 28 repeat breeder HF crossbred cows during their post-partum period in their second to seventh lactation from different villages of Satara District. Health status was ascertained through clinical examination. All the animals selected were devoid of genital abnormalities. Blood serum was separated from collected samples and analyzed for certain biochemical parameters viz. protein, albumin, globulin, cholesterol, calcium, phosphorus and blood urea nitrogen. These serum biochemical constituents were compared with their serum levels in normal cyclical and repeat breeder cattle reported by various research workers. Blood Urea Nitrogen, Globulin, and Albumin/Globulin ratio do not play a significant role in causing Repeat Breeding problems in crossbred cows and underlines the importance of other serum biochemical parameters like protein, albumin, cholesterol, calcium, and phosphorus in diagnosing the cases of RB crossbred cows. Further studies are required to validate the findings of the study.
