Abstract:This experiment aims to study the effects of traditional Chinese medicine feed additives on the immune function, amino acids and immune function of Gannan Tibetan sheep. We randomly divided 60 Tibetan sheep into 6 groups, which were 3 control groups and 3 experimental groups, with 10 Tibetan sheep in each group. The basal diet of the experimental group was supplemented with 1% of locally sourced sevenflavor traditional Chinese medicine feed additives. The pretest period is 10 days and the formal test period is 90 days. The results showed that the immune function, amino acids and fatty acids of Gannan Tibetan sheep in the control group were significantly improved compared with the experimental group (P< 0.05). Tests have shown that adding traditional Chinese medicine feed to the diet of Gannan Tibetan sheep can significantly improve the immune function, amino acids and fatty acids of Gannan Tibetan sheep. This shows that adding different doses of Chinese medicinal materials is beneficial to the healthy development of Tibetan sheep.
