An experiment was conducted on Nadooshan goats of Iran, during the breeding season, to evaluate the effectiveness of flushing and equine chorionic gonadotropin (eCG) treatment on reproductive traits.Ninety-two intact does with an average live weight of 25.11 ± 3.933 kg were randomly divided into four equal experimental groups. Controlled internal drug release device (CIDR) were inserted for 18 days inall groups. Experimental groups consist of: 1- Control (C); 2- eCG (600 IU; E); 3- eCG (600 IU) + Flushing (E+F); and 4- Flushing (F). Does in two last groups (E and E+F) were injected intramuscularly, at the timeof CIDR withdrawal, with 600 IU of eCG. The first group (C) received no treatment and served as a control. All animals were submitted to pasture and mineral licks and groups E+F and F additionally received flushing ration. Pregnancy rate in group F was more than the control group (p < 0.05). Twinning rates and kid crops in groups E+F and F were significantly higher than control group (p < 0.05). Time of onset of estrus decreased in groups with eCG administration (E and E+F). Therefore, it is concluded that the flushing especially coupled with the eCG treatment can improve reproductive performance in Nadooshan goats treated with CIDR during the breeding season
