is a Chinese medicine with a long history in which stems and leaves are the wastes of processing and have not been effectively utilized. The effects of diets containing stems and leaves on the cecal short-chain fatty acid (SCFA) concentration and microbiome of independent pigs were studied. Diets containing stems and leaves did not affect the concentration of SCFA in the cecal contents of Duzang pigs but affected the microbial composition and diversity. Firmicutes, Proteobacteria, and Bacteroidetes dominate in the cecal of Duzang pigs. Feeding Duzang pigs with a 10% stems and leaves diet increases the abundance of , , and in the cecal. We found 14 genera positively associated with acetate, and they were , , and showed negative correlations. , , and were positively associated with propionate. , , and were positively associated with butyrate. In conclusion, stems and leaves could affect the cecal microbial community and functional composition of Duzang pigs. stems and leaves reduce the enrichment of lipopolysaccharide biosynthetic pathway of the cecal microbiome, which may have a positive effect on intestinal health. The higher abundance of GH25 family in Duzang pig's cecal microbiome of fed stems and leaves diet. This increase may be the reason for the microbial diversity decrease.
是一种历史悠久的中药，其茎叶是加工废弃物，未得到有效利用。研究了含茎叶日粮对杜藏猪盲肠短链脂肪酸（SCFA）浓度和微生物群的影响。含茎叶日粮对杜藏猪盲肠内容物中SCFA浓度无影响，但影响微生物组成和多样性。厚壁菌门、变形菌门和拟杆菌门在杜藏猪盲肠中占主导地位。用10%茎叶日粮饲喂杜藏猪可增加盲肠中、和的丰度。我们发现14个属与乙酸盐呈正相关，它们是，，和呈负相关。，和与丙酸盐呈正相关。，和与丁酸盐呈正相关。总之，茎叶可影响杜藏猪盲肠微生物群落和功能组成。茎叶减少了盲肠微生物群落脂多糖生物合成途径的富集，这可能对肠道健康有积极影响。饲喂茎叶日粮的杜藏猪盲肠微生物群中GH25家族丰度较高。这种增加可能是微生物多样性降低的原因。
