Induction of Estrus in Postpartum Anestrus Crossbred Cattle

The present experiment was designed for estrus induction in post-partum anestrus cattle. A total of 120 cows were examined reproductive status, and 30 incorporated induction, including 24 6 normal cyclic cows. assigned to 5 groups (6 animals per group). group-1 induced using Ovsynch protocol, while group-2 inserted TRIU-B (958 mg progesterone) intra-vaginal inseminated at a fixed time. group-3 supplemented with standard chelated mineral mixture 40 g per-oral daily 45 days on observed estrus. Group-4 included untreated group-5 control Estrus response 100% 1 2, 66.66%, 0.00% 3 5, respectively. conception rate 1, 3, 4 33.33%, 50.00%, 75.00%, 83.33% 0.00%, mean serum progesterone different increased non-significantly from 0 21 post- insemination. All groups’ calcium significantly day 21. However, the phosphorus showed no such significant differences between within groups. It noticed that overall Ca:P ratio disturbed (Ca being lower side) under study, which might be attributed animals’ condition. In conclusion, Ovsynch, TRIU-B, proved useful ovulation enhancement pregnancy
