Abstract

Aim: The study was aimed to determine the reproductive performance and identify the potential risk factors associated with reproductive performance of smallholder dairy cattle.

Method and Materials: This study was conducted in mareka woreda dawuro zone, southern ethiopia and about 90 cattle owners were interviewed and 384 dairy cattle of local and HF cross breed were included in the study.

Results: The results revealed that the mean age at first service in local breed was found to be 30.32±3.8 months and in HF cross breed 20.31± 2.56 months, whereas mean age at first calving was 40.42± 5.00 months in local breeds and 30.64± 3.53 in exotic breeds respectively. The mean days open was 69.62± 8.43 and 65.41± 12.06 days in local and exotic breeds respectively. Number of service per conception was 1.62± 0.87 in local and 1.40± 0.76 in exotic breeds. And also mean calving interval was found to be 16.86± 3.23 and 12.48± 1.68 months in local and exotic dairy cows respectively. The overall prevalence of reproductive performance disorders in current survey was indicated as abortion (27.6%), retained fetal membrane (38.3%) and repeated breeding (25.5%) and Anoestrus (8.6%).

Conclusion: It was concluded that decreased reproductive performance due to poor management as a result there is low economic gain to the owners. Therefore, improved management system should be practiced purposively to enhance the reproductive performance of dairy cattle breeds.
