Evaluations of the productive and reproductive performances of indigenous dairy cows were carried out in Alfa and Quadra districts under smallholder farmer’s management system. To collect data from 376 households, a cross sectional study were employed via structured questionnaires. To assess the reproductive performance of the dairy cows, age at first services (AFS), age at first calving (AFC), calving interval (CI), days open (DO) and number of service per conception (NSPC) were utilized as an indicator traits. In addition, milk yield per day (MY/D), lactation milk yield (LMY) and lactation length (LL) were considered as an indicator of the performance productive traits.
