Improving the Reproductive Efficiency of Dairy Cows through Double-Prostaglandin Hormone Injection in Gamo Zone, SNNP

Abstract

The study was aimed with the objective to evaluate on-farm response and conception rate by double injection of prostaglandin hormone to induce cows’ oestrus in Chencha and Arbaminch Zuria districts. The data were analyzed by employing simple descriptive statistics (frequency and percent) to present oestrus response and conception rate. The current findings revealed that the overall response and conception rate were 71.64% and 49.92%, respectively. However, both the response and conception rate to hormone injection were higher in Chencha district (72.72% and 56.25%, respectively) than in Arbaminch Zuria (69.56% and 31.25%, respectively) district. The variation may be attributed with agro-ecology difference since Chencha district was highland where as Arbaminch Zuria was considered as lowland. From the current result, cconception rate was lower than the response rate. This could be associated with heat detection problems of farmers, timing of insemination and poor husbandry practice of cows. Hence, choices of technically right and practically feasible protocol under on-farm conditions were essential to increase the response and conception rate.
