Abstract

The present work was carried out on thirty Sahiwal cows selected from different villages in and around Rewa city of Madhya Pradesh. They were divided into 5 equal groups (n=6 each) to study the effect of clomiphene citrate, co-synch protocol and mineral supplementation alone or in combination on estrus induction, hormone concentration and fertility. Group 1, animals were fed ration containing 0% mineral mixture; Group 2, were fed ration containing clomiphene citrate (300 mg/ day for 5 days). In Group 3, the animals were subjected to co-synch protocol with fixed-time artificial insemination (FTAI) on day 11. Group 4 animals were fed ration containing a mineral mixture 1% and clomiphene citrate (300 mg/ day for 5 days). In Group 5, the animals were fed ration containing mineral mixture 1% and subjected to co-synch protocol. A significant difference was seen in progesterone concentration on day 42 and 60, while in estrogen, a significant difference was seen on day 9. Maximum conception rate (60%) was observed in animals that were supplemented with mineral mixture along with co-synch protocol (G5) followed by 50% with co-synch protocol alone (G3), and least conception rate (i.e., 0%) was observed in control group (G1). In group 4, mineral mixture supplementation with clomiphene citrate, no significant increase in fertility rate (33.33%) was noted. However, a higher estrus induction rate (50%) was observed, whereas in group 5 mineral mixture supplementation along with co-synch protocol increased the estrus induction (83.33%) and fertility rate (upto 60%) in anestrus Sahiwal cows.
