Abstract

This experiment was carried out to investigate the Moghani ewe production performance improvement through reproductive management and nutrition methods during the non-breeding season in rangeland condition. For doing these projects, in one flock with 400 ewes, two groups were identified, that including group 1(estrus synchronization+hormone therapy+supplementary feeding) and group 2 or control group (without estrus synchronization+ hormone therapy+supplementary feeding). Supplementary feeding duration in pre mating for 4 weeks and 1.5 month in late gestation with concentrate were done. During the project, production, reproductive traits and economical evaluation was carried out in each two groups. For quantities data analysis of T-test methods and for qualitative traits were used of frequency table and Chi-square. The results showed that, parturition rate, lamping rate, twining rate, born lamb crop (BLC) and weaned lamb crop (WLC) in experimental group was more than control group (p<0.05). In terms of fecundity, there was significant statistical difference between two methods, so that 104.21 vs. 48.64 percent in experimental group compared with control group were observed (p<0.05). In conclusion, in non-breeding season, in Moghani ewe using of estrus synchronization+hormone therapy+supplementary feeding, have the highest economic interest compared to the control group.
