Comparing the effects of sponge and CIDER on vaginal health, estrous synchronization, and reproductive performance in ewes

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..
