The results in this study showed superior significantly (p<0.01) in 2nd group related with animals response compared with 1st and 3rd group as well as significantly between 1st and 3rd group, while the duration of response was recorded highly significantly (p<0.01)for the treated groups (1st&2nd) compared with control group( 3rd) . But the number of services per conception which recorded non significantly (p<0.01) between all groups, while the pregnancy rate was recorded 100%, 90% and 100% in 1st ,2nd and 3rd groups respectively with significantly (p<0.01) related with 1st and 3rd compared with 2nd group. Finally the days open recorded 94.13±7.01 , 97.24±6.78 and 153.57±12.64 in 1st, 2nd and 3rd groups respectively with highly significant for 1st and 2nd compared with 3rd group. In conclusion in this study that they used hormonal treatments (CIDR +PMSG ) for induction of fertile estrus was safe and effect for increasing pregnancy rate and reduction days open.
