| 520 | 3 | |a The object of the study was to find the incidence of postpartum suboestrum in crossbred cattle and to evaluate the efficiency of PGF2 alpha (Estrumate) in the treatment of suboestrum. For this, the crossbred cows belonging to the University Livestock Farm, Mannuthy which were reported to be anoestrous even after 45 days postpartum were subjected to detailed clinic gynaecological examination and those having palpable corpus luteum were considered as suboestrous. Among these, 54 cows which had an active corpus luteum of 7 – 14 days of age were given 500 microgram of Estrumate and the result of the treatment was assessed. The observations made and inferences drawn are summarised below. The incidence of postpartum suboestrum in the herd was 45.68% and in the reportedly anoestrous animals 71.84% were suboestrous. In all, 98.15% cows exhibited cestrus at an average interval of 53.2075 + 1.038 hours, after the administration of the drug. Among these 92.45% ovulated at an average interval of 82.6122 + 2.0015 hours after the administration of Estrumate. The percentage of treated animals which conceived at first insemination was 43.4. The conception rate in the induced heat was significantly influenced by the intensity of heat. The number of inseminations required per conception did not vary significantly from that of the rest of the herd. The service period of the treated animals was significantly shorter (92.4583 + 3.5394) than that of the herd (135.11 + 6.9742) days. In short, it may be stated that PGF2 alpha analogue, Estrumate, was effective in the induction of ovulatory oestrum with satisfactory fertility in the suboestrous cows. | |
