With the rapid development of sequencing technology, research on pigs has focused on intestinal microbes. Accumulating evidence suggests that the metabolites of intestinal microbes are the key medium for interactions between microbes and the host. Amino acid metabolism is involved in the growth and immune processes of pigs. The gut microbes of pigs are heavily involved in the metabolism of amino acids in their hosts. Here, we review the latest relevant literature. Research findings show that microbial metabolites, such as indoles, short-chain fatty acids, and ammonia, play a key role in gut health. Moreover, we summarize the effects of amino acids on the structure of the gut microbial community and the metabolism of amino acids by pig gut microbes. Evidence shows that microbial amino acid metabolites act as signal molecules in the intestine and play an important role in the intestinal health of pigs.

随着测序技术的快速发展，对猪的研究主要集中在肠道微生物上。越来越多的证据表明，肠道微生物的代谢产物是微生物与宿主相互作用的关键介质。氨基酸代谢与猪的生长和免疫过程有关。猪的肠道微生物在很大程度上参与了宿主体内氨基酸的代谢。在这里，我们回顾了最新的相关文献。研究结果表明，吲哚、短链脂肪酸和氨等微生物代谢物在肠道健康中发挥着关键作用。此外，我们总结了氨基酸对肠道微生物群落结构和猪肠道微生物氨基酸代谢的影响。
