Abstract:In this experiment, mutton sheep with a body weight of about 30kg were selected. On the basis of the same basic diet, fermented wheat straw containing Chinese herbal medicine and unfermented wheat straw were added respectively. We detect the growth of mutton sheep weight gain. The results showed that the mutton sheep were fed with fermented wheat straw containing Chinese herbal medicine, and their daily gain and daily income were better than those of the control group. The breeding benefits of this method are relatively obvious.
