Failure of estms detection and improper timing of insemination has been the single most known factor in dairy animals. In this study, the perfomlance of the conventional method of AI delivery was evaluated to compare with improved estrus detection method through artificial estrus vaginal mucus discharges were found to be the most common estrus manifestations observed byconventional insemination service was 2.34±0.OS . Bellowing, standing to be mounted andininduction. Pregnancy rate was compared between dairy animals inseminated by the conventional way and those inseminated after estrus induction using synthetic prostaglandin. Pregnancy rate for the whole of the study group using AI was 42.9%. There was also a significant breedfor the whole of the study group using AI was 42.9%.
