The aim of the present study was to compare sponge and cider with two different brands in estrous synchronicity, vaginal health and off-breeding performance in Moghani ewes. For this purpose, 120 ewes of Moghani breed were selected and randomly divided into four experimental groups. Ewes in the first and second groups, using sponge Sponjavet and CIDER Eazi breed (as valid and common brands) for 12 days, respectively, and the third and fourth groups, respectively, using sponge Fluorojest and CIDER Progest (as New brands made jointly by Iran and China) were treated for 12 days. Ewes in all groups received 400 IU units of eCG at the time of sponge and cider harvest. The rate of vaginal mucosal discharge and adhesion in sponge was higher than cider (P< 0.01). However, there was no significant difference between reproduction and progesterone concentrations between CIDER and sponge as well as brands of these two tools.Therefore, due to lower price and similar efficiency, Sponge Fluorojest and CIDER Progest can be considered as an appropriate alternative to common commercial sponge and CIDER..

The aim of this study was to evaluate the effect of glycogenic diets supplemented with different poly unsaturated fatty acids on reproductive performance of Iran Black ewes in two different managing programs. Ewes were allocated in two different groups; group A (n = 75) and group B (n = 25). Ewes from group A were stopped from suckling followed by introducing to the rams on days 80 and 90, respectively. Melatonin implant was laid under the skins ear of these ewes 40 days before introducing them to the rams. Animals from group A were divided into three groups (25 ewes/sub-group) and were fed by high starch diets supplemented with saturated fatty acids (control diet), extruded linseed (omega 3 diet), and full fat soybean (omega 6 diet). Ewes from group B were stopped from suckling on day 120, introduced to the rams on day 180 after parturition and fed as described for the control diet. Data for the rates of Estrus cycle, ovulation, lambing and twining were recorded for each group. The weight of lambs was measured at the birth time of birth, and also at 3 and 4 months of age. The lambing and twining rates were higher in omega 3 and omega 6 diets as compared with the control diet and group B. Animals in group B indicated a higher lamb weight at 3 and 4 months of age compared to all treatments in group A. In conclusion, data from current study suggested that using management program of group A along with feeding omega 3 and 6 could improve the reproductive performance of Iran Black ewes.
