Abstract :
Ewes have seasonal estrous cycle so Estrus synchronization is a valuable way to manage ewes reproduction . Due to the existing conditions and some problems in preparation of PMSG in Iran, we should looking for an alternative method , Therefore, in this study Comparison of estrus synchronization and fertility in Afshar sheep out of breeding season was done with these methods.- Group1 CIDR+PMSG. -Group2 CIDR+HMG. -Group3 CIDR+HMG+Estradiol.200 non-pregnant Afshar ewes are divided randomly in 4 different groups (n=50). Estrus was synchronized in all groups by using Abu Reihan progesterone CIDR for 12 days. At the CIDR removal, in group1 any treatment were not received ,in group2 they were received PMSG(500 UI),in group3 they were received HMG (1 vial) and finally in last group they were received HMG(a vial) + Estradiol(0.1 mL). The results of Incidence of estrus and fertility symptoms in the groups were analyzed. P value between the first and Second group was not significant(P value <0.05), which seams there is no significant difference between these two groups.The results from the occurrence of estrus and fertility in ewes were analyzed. Therefore, to replace PMSG , using HMG in estrus synchronization of ewes can be a good way.
