Abstract

This study was conducted in urban and rural areas of Adami Tullu district with objectives of evaluating factors affecting the efficiency of AI under farmers' situation and suggests options to be considered for improving the efficiency of AI delivery system. The overall conception rate attained in the study was 48.30% which is better than the national average conception rate reported so far.  It was found out that the proportion of cows that successfully conceived significantly differed (P < 0.05) between the two locations (35 vs. 64.6%, for rural and urban, respectively). Moreover, overall conception varied with breed of cattle (P < 0.05), indigenous cattle (Arsi cows) attaining lower conception than the crossbred cattle. No significant differences were observed in conception rate among parities of cows and management system of cattle. There was a tendency of enhanced conception with increase in body condition of cows, although the effect was not significant. Over the 4-month period of supplementation, 60% of supplemented and 30% of control cows exhibited estrus (P>0.05) and the pregnancy rate was higher in supplemented than in control cows (42.9 vs 25%; P>0.05).
