EFFECT OF OVSYNCH TREATMENT ON BLOOD BIOCHEMICAL CONSTITUENTS AND CONCEPTION RATE IN RETAINED FETAL MEMBRANES AFFECTED AND NORMALLY CALVED 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 supplemented orally daily with 30-50 g mineral mixture continuously for 15 days. At the endof mineral mixture supplementation, all the cows of both the groups were treated with ovsynch protocol. The mean blood glucose, serum total protein, cholesterol, triglycerides, calcium and phosphorus levels were found to be lower in RFM affected cows than NC cows at i) the time of animal selection (ii) the initiation of ovsynch treatment (iii) PGF^a injection (iv) Timed artificial insemination (TAI) and (v) 10 days following TAI. Further, in both the groups, there was an increasing trend in all these blood constituents from selection to 10 days post Al. The conception rate obtained was 87.50 and 75.00 percent, respectively. It is concluded that ovsynch programme influenced the levels of blood constituents and improved conception rate in RFM affected and NC cows.
