Abstract:

The aim of this experiment was to study the effects of Chinese medicine Jianpisiwei formulas on the growth performance, rumen fermentation and microbiota composition of weaned Hu sheep. A total of 100 healthy 2-month-old Hu sheep with average body weight of (14.55±0.21) kg were randomly divided into 5 groups with 4 replicates in each group and 5 sheep per replicate. The control group was fed with basal diet, A1 and A2 groups were fed basal diet supplemented with 0.3% and 0.5% Jianpisiwei formula A, the B1 and B2 groups were fed basal diet supplemented with 0.3% and 0.5% Jianpisiwei formula B. The results showed that compared with the control group, the average daily weight gain of the A2 group was significantly increased (P < 0.05), the feed-to-gain ratio was significantly decreased (P < 0.05), the content of ammonia nitrogen (NH3-N) in the A1 and B2 groups was significantly increased (P < 0.05), the content of microbial protein (MCP) was significantly decreased (P < 0.05), the pH value of the the A2 group was significantly decreased (P < 0.01), and the content of propionic acid was significantly increased (P < 0.01). The ratio of acetic acid to propionic acid was significantly decreased (P < 0.01), the total volatile fatty acids were significantly increased (P < 0.01), the number of species and Chao 1 index in the the A1 and A2 groups were significantly increased (P < 0.05), the Shannon index was significantly increased (P < 0.01), the relative abundance of Spirochaetota was significantly decreased (P < 0.01), and the relative abundance of Euryarchaeota in the A2 group was significantly increased (P < 0.01);The relative abundance of Rikenellaceae_RC9_gut_group and Eubacterium_ventriosum_group in the A1 and A2 groups decreased significantly (P < 0.05), while the relative abundance of Bacteroidales_RF16_group increased significantly (P < 0.05). The relative abundance of Selenomonas in the A2 group was significantly decreased (P < 0.05), while the relative abundance of Quinella increased significantly (P < 0.05). The above results indicated that the addition of Chinese medicine Jianpisiwei formulas to the diet could promote the growth performance, improve rumen fermentation, and increase the diversity and richness of rumen flora in weaned Hu sheep.
