Sažetak
The objective of this study was to measure the effect of vitamin E (Vit-E) and zinc (Zn) supplements on endocrine and metabolic changes in peripartum cows. Thirty-two crossbred (Holstein Friesian×Tharparkar) cows were selected 60 days before the expected date of calving. The cows were arbitrary allocated into 4 groups (n = 8), namely: the control, T1, T2, and T3. The feeding schedule was similar in all the groups except that in T1, T2, and T3 60 mg Zn/kg DM, 1000 IU Vit-E and 60 mg/kg + 1000 IU Zn + Vit-E were additionally added, respectively, from day 60 pre-calving to day 60 post-calving. Blood samples were taken on days 60, 45, 30, 15, and 7 before and after the expected day of calving and on the day of calving. Before calving, the cows showed a decrease in plasma leptin, insulin, glucose, Vit-E, and Zn levels, and an increase in plasma non-esterified fatty acid level. However, increases in plasma leptin, insulin, glucose, Vit-E, and Zn and a decrease of plasma non-esterified fatty acid were observed after calving. After calving, group T3 had higher (P<0.05) plasma leptin, insulin, and glucose concentrations than all the other groups. Plasma Vit-E levels were higher (P<0.05) in groups T2 and T3; however, the Zn level was higher (P<0.05) in groups T1 and T2. Milk yield was observed to be higher (P<0.05) in T3 than in the control and groups T1 and T2. The reduction in leptin, insulin, glucose, Vit-E, and Zn during peripartum was ameliorated by Vit-E and Zn supplementation
