Ovsynch Treatment Protocol Improved the Conception Rate in Retained Fetal Membranes (RFM) Treated Cows

摘要

Eight cows treated (Group I) for retained fetal membranes (RFM) and 8 normally calved (NC) cows (Group II) were selected around day 35-50 post-partum and were orally supplemented daily with 30-50 g mineral mixture for 15 days. The cows of both the groups were treated with ovsynch protocol. The mean serum progesterone (ng/ml) levels were found to be higher in RFM affected cows than NC cows and oestradiol-176 (pg/ml) levels were found to be lower in RFM affected cows than NC cows. Further,the mean serum P? levels were increased from the time of animal selection to the time of PGF2a injection but at first Al the mean serum levels decreased to less than 1 ng/ml and at 10 days post Al, an elevation of mean serum P_4 level were noticed in both the groups. The mean serum E2 levels were found to be increased from the time of animal selection to the time of first Al but at 10 days post Al the mean serum E_2 levels got decreased in both the groups. The conception rate obtained was 87.50 and 75.00 per cent, respectively. It is concluded that ovsynch programme influenced the levels of blood endocrine profiles and improved conception rate in RFM affected and NC cows.
