Abstract: In order to solve the shortage of feed in desert steppe in winter and to develop the abundant Caragana resources that cannot be utilized by domestic animal,the Caragana fermented TMR feed was developed and the contrast test of feeding effect with conventional feeds in ewes was conducted in this study. The results showed that while there were no significant differences between the intake of three Caragana fermented TMR feed, there were significant differences between the intake of three Caragana fermented TMR feed and the pellet feed. During the feeding experiment ,the Caragana fermented TMR feed could maintain normal production performance of ewes, meanwhile, its feeding cost was lower than that of conventional fermentation feed and far lower than the pellet feed. It was indicated that Caragana fermented TMR feed could replace the conventional feed as a substitute for retention-fat, anti-disaster and animal protection in winter.
