Abstract

In order to study the effect of male on reproductive behavior of female goats, 88 Markhoz breed goats with initial body weight of 42±2kg, 3.5 year old, and 10 male goats were used for 6 weeks. This study was conducted in two phases. In the first experiment 48 female goats were allocated in three groups, each group included eight animals with 2 replicate on both sides of male goats, respectively, at intervals of 0-5, 10-15 and 25-30 meters. In the second experiment, 24 female goats having CIDR were used in an order similar to that of first group. However, the goats were located only in one side of the males. The third group was the control group which was treated in a separate saloon in two groups, each of them having eight animals in it. Results showed a significant effect of male animal in estrus synchronization, the earlier beginning of the reproductive cycle and fertility in the early reproductive season. The first group showed better results in creation and synchronization of estrus in comparison to CIDR received animals (respectively 116.7 vs. 91.6%).
