Title: Comparison of reproductive efficiency of beetal goats in different breeding systems
Author: ElYas, Ibtisam
Abstract: In this study, reproductive efficiency of two adults beets! goat flocks was (Flock A=47, Flock B=25) compared under seasonal and year-round breeding systems. One year data of goats of comparable age were collected and analyzed during the same period of time. In flock A, a male was allowed to breed for 45 days during autumn when daylight length was decreasing. In flock B, a male was allowed to breed round the year. There was no significant difference between the conception rates and average age at puberty in both flocks. The average kidding interval was significantly shorter in flock B (119±15 days) compared to flock A (314±20). There was no effect on the weight of male and female kids. Goats in flock B produced 33% more kids compared to flock A. Total running cost of flock B was 9% higher than of flock A but flock B. The abortion and mortality rates were comparable in both flocks. It is concluded that beetal goats can reproduce efficiently round the year in Pakistan without any seasonal limitations.
