Abstract:
Postpartum infertility due to negative energy balance is a major problem among the high producing cows of Kerala, incurring huge economic loss. The present study was aimed to evaluate the effect of supplementation of bypass fat on glucose and insulin levels of postpartum crossbred cows. The trial was conducted with four experimental groups of six cows each (GI – control; GII- 200 g bypass fat; GIII – 200 g bypass fat daily + Ovsynch protocol; GIV – Ovsynch protocol alone). The mean blood glucose levels (mg/dl) during the experimental period were 45.78±1.75, 69.82±1.78, 69.45±1.53 and 45.33 ± 0.91 in GI, GII, GIII and GIV respectively. The mean blood glucose levels were significantly (P<0.01) higher in GII and GIII compared to the other two groups. It was observed that the mean serum insulin levels were significantly higher (p<0.05) in GII and III compared to the other two control groups. The mean insulin values were 7.04±0.28, 8.02 ± 0.29, 8.10 ± 0.28 and 7.00 ± 0.35 µ IU/ml respectively in GI, II, III and IV. The results of present study proved that bypass fat feeding is a natural way of improving the energy status of lactating animals, thereby enhancing the reproductive efficiency.
