Background: Starting with 2012 up to 2020 in Silte zone many cows were synchronized and inseminated. However, there were a failure of Conception Rate after synchronized and inseminated and so far the mechanisms of failure of Oestrus Synchronization and Mass Insemination in conception were not understood. Therefore, the aim of this study was to determine the cause of failure of Oestrus Synchronization and Mass Insemination in conception of dairy cattle.

Result: Among the 130 injected cows, 72 (55.38%) of them were responded from day 2 up to day 3 after hormone treated and then inseminated them. As a result, the quality of semen in Dalocha and Sankura districts was facing with quality problem. There was AIT efficiency difference on Conception Rate based on their work experience in this study. Low no of AIT and mass number of cow provide during OSMI, lack of awareness about heat detection of farmers and cows not properly managed after hormone and semen treated were the main cause of failure of Conception Rate which is ranked 1 up to 3.

Conclusion: Generally, there is a great need of skilled and experienced technician and capacity building of farmers in heat detection, husbandry practices, and good handling practice of semen in the office and improvement strategy. Therefore, improvement in facilities and management should be necessary before implementing an effective estrous synchronization and mass Artificial Insemination programs.
