Author(s): Serum biochemical profiles between repeat breeder and normal cyclic jersey crossbred cows

Abstract: The present study on serum biochemical constituents was carried out in repeat breeder and normal cyclic Jersey crossbred cattle. A total of 32 healthy Jersey crossbred cattle (n=32), aged 3-6 years with body condition score of 5-6 were selected and divided into two groups, each group comprised of twelve (n=16) animals (Group I: Repeat breeder, Group II: Normal cyclic). As per the schedule of the farm, experimental cows were properly vaccinated and dewormed. In morning, prior to concentrate feeding, the blood samples were collected in heparinized vacutainer and immediately transported to the laboratory. The blood samples were centrifuged at 3000 × g for 15 min. Serum samples were separated and kept at -20 °C until estimation of biochemical profiles. Concentration of serum total protein, albumin, globulin, glucose and creatinine was significantly (p<0.05) higher in normal cyclic as compared to repeat breeder. However, in repeat breeder cows had significantly higher concentration of total cholesterol and BUN as compared to normal cyclic cows. Similarly, Calcium concentration was significantly higher in normal cyclic group as compared to repeat breeder. However, the serum P was non significantly higher in repeat breeder as compared to normal cyclic group. These serum biochemical constituents might have played a vital role in the physiological cyclicity of these cows, and these essential nutrients could be added in diet to avoid repeat breeder syndrome in Jersey crossbred cows.
