The objectives of this study were to assess the hormonal response, conception rate, calving rate and perception of farmers towards the technology. From 220 cows and heifers brought by farmers for the services, 65% (143) that fulfilled the selection criteria were selected and injected with 2 ml of Cloprostenol. Data on the history of each heifers and cows, number of heifers and cows responsive to hormonal treatment, conception and calving rates were collected. The collected data were analyzed using descriptive statistics. The results of the finding showed that 91(63.64%) of cows and heifers were responsive to hormonal treatment. Majority 81(89.01%) of responding cows and heifers were inseminated. Finally, 11(13.58%) of calves were delivered. Oestrus response rate was relatively high, but conception rates and calving rates were very low. The lower percentages of conception rate which was observed in this study were associated with heat detection problems of farmers, distance from artificial insemination (AI) service centers, timing of insemination and poor husbandry practice of heifers and cows. To improve the effectiveness of the technology, there is a great need of skilled and experienced technician, and capacity building of farmers in heat detection and husbandry practices. Improvements in facilities and management should be necessary before implementing effective estrous synchronization and mass artificial insemination program.
