Abstract:
Postpartum infertility due to negative energy balance is a major problem among the high producing cows of Kerala, incurring a huge economic loss. The present study aimed to evaluate the effect of supplementation of bypass fat on blood biochemical parameters and circulating hormonal levels. 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). It was observed that the total cholesterol (P<0.01) levels were significantly higher and triglycerides (P<0.01) levels were significantly lower in those animals fed with bypass fat, compared to others. The mean circulating blood progesterone levels were observed to be significantly higher (P<0.01) in animals fed with bypass fat. The results proved that dietary supplementation of bypass fat modulates the blood biochemical parameters and hormonal profile of postpartum cows, making them fit for an early resumption of ovarian activities.
