Efficacy of Ovsynch and Ovsynch based GnRH treatments on conception rate in postpartum anestrus crossbred cows

Abstract

A total of fourty (40) numbers of apparently healthy postpartum crossbred cows of 1st to 4th parity with normal calving history and free from any immediate post-parturient complications were selected to study the efficacy of Ovsynch and Ovsynch based GnRH (G6G) treatments on conception rate. The animals were divided equally into two groups, i.e., Group A and Group B for the therapeutic management. All the experimental cows were maintained under standard feeding and managemental conditions. The study was carried out at the Department of Animal Reproduction, Gynaecology and Obstetrics, College of Veterinary Sciences & Animal Husbandry, Central Agricultural University, Selesih, Mizoram. The conception rate for group A and Group B were 40 and 60 per cent respectively. So, in conclusion the Conception rate for Group B i.e., G6G protocol was higher than the Group A i.e., Ovsynch protocol.
