Dietary pectin Modulate Inflammatory Response by Gut Microbiota-Derived Tryptophan Metabolites

Pectin is a heteropolysaccharide that acts as an intestinal immunomodulator, promoting intestinal development and regulating intestinal flora in the gut. However, the relevant mechanisms are still not clear. In this study, pigs were fed on a corn-soybean meal-based diet supplemented with 5% microcrystalline cellulose (MCC) or 5% pectin for 3 weeks, to investigate the metabolites and anti-inflammatory in the jejunum.

果胶（Pectin）是一类可充当肠道免疫调节剂的杂多糖，能够促进肠道发育并调节肠道菌群。然而，其相关作用机制目前仍不明确。本研究中，试验猪被喂食添加5%微晶纤维素（microcrystalline cellulose, MCC）或5%果胶的玉米-豆粕基础日粮，饲养周期为3周，以探究空肠中的代谢产物与抗炎活性。
