- Abstract
The study was to explore the effect of different Artemisia polysaccharide combination supplementation preparations on intestinal microbiota diversity of Tan lambs. A total of 60 Tan lambs were randomly divided into four groups, with 15 replicates in each group and one sheep in each replicate. Tan lambs in control group were fed with basal diet. Tan lambs group 1, group 2 and group 3 were supplemented with 5.5 g/d Artemisia polysaccharide +5.5 g/d coated sodium butyrate, 5.5 g/d Artemisia polysaccharidee +5.5 g/d butyrate, 5.5 g/d Artemisia polysaccharide +1.1 g/d monensin in basal diet, respectively. The experiment lasted for 60 d. The results showed that the relative abundance of Firmicutes in duodenum and Verrucomicrobia in ileum of group 2 were significantly higher than that of control group (P<0.05), and the relative abundance of Actinobacteria in jejunum of group 3 was significantly higher than that of control group (P<0.05). The relative abundances of Sharpea and Solanum_torvum in duodenum of group 1 were lower than that of control group (P<0.05). The relative abundances of Solanum_torvum in duodenum of group 2 was significantly lower than that of control group (P<0.05), and the relative abundance of Acetitomaculum was significantly higher than that of control group (P<0.05). The experiment indicates that the combination of Artemisia polysaccharide in diet can increase the diversity of bacteria, improve the intestinal microflora of Tan lambs. Artemisia polysaccharide + coated sodium butyrate group and Artemisia polysaccharide + butyrate glyceride group have better effect.
