The study was conducted on eighteen dystocia affected Dangi cows to evaluate the effect of ecbolic therapy on postpartum reproductive parameters as well as serum progesterone and estradiol-17β profile. The cows were randomly divided into three groups, each of 6 animals. The cows in Gr-I and Gr-II were injected with Methyl ergometrine (5 mg) and Dinoprost tromethamine (PGF2α, 25 mg) i/m, respectively, immediately after parturition and the cows of Gr-III received herbal ecbolic boli (2-4 boli, bid, PO) for first 10 days postpartum. The blood samples were collected on 0 day (day of calving), 7th day, 14th day, 21st day and 28th day postpartum from the jugular vein. The mean first postpartum estrus interval in Gr-I, Gr-II and Gr-III were 181.50 ± 44.73 days, 195.33 ± 23.38 days and 155.33 ± 27.81 days. The service period was 237.66 ± 28.01 days with 50 per cent (3/6) conception rate in Gr-I and 402.00 ± 46.12 days and 368.66 ± 53.46 days with 100 per cent (6/6) conception rate in each Gr-II and Gr-III, respectively. The postpartum estrus interval and service period did not differ significantly (p>0.05) between Gr-I, Gr-II and Gr-III. A highly significant (p less than 0.01) decrease in both progesterone and estradiol-17β concentration was observed on 7th day postpartum and thereafter fluctuated non-significantly with increasing trend on 14th , 21st and 28th day postpartum in all groups. |
