玉米麸 (CB) 已被用作猪的原料，但改善肠道健康的潜在机制尚不清楚。本研究旨在探讨日粮CB对断奶仔猪生长性能、营养物质消化率、与肠道激素和免疫相关的血浆指数、肠道微生物群组成和发酵产物的影响。总共60头断奶仔猪被分配到两个日粮处理组，每组仔猪接受对照（CON）日粮或5%CB日粮，为期28天。评估生长性能、营养物质消化率、肠道激素指数和血浆免疫力。使用 16S rRNA 扩增子测序测定粪便中的微生物群组成，并通过高效离子色谱法测量发酵产物。结果显示，试验中日粮CB不会影响生长性能、营养物质消化率、肠道激素或发酵产物（P > 0.05）。 CB 的加入对白细胞介素 10 的产生有增加的反应 (P < 0.05)。第 28 天，饲喂日粮 CB 的仔猪具有较高的香农指数 (P < 0.05)。 CB处理后厚壁菌门数量减少（P < 0.05），而拟杆菌门比例增加（P < 0.05）。尤其是与谷麸多糖发酵相关的Eubacteria corprostanoligenes、Pevotella和Fibrobacter的数量有所增加（P < 0.05）。总之，含5%CB的断奶后日粮增加了仔猪肠道微生物多样性，特别是纤维溶解菌的丰富度，并在一定程度上促进了仔猪的抗炎反应，这些变化应有利于仔猪消化系统在后续生长阶段的适应。
Corn bran (CB) has been used as an ingredient for pigs, but the underlying mechanisms that improve gut health is less clear. This study was conducted to investigate effects of dietary CB on growth performance, nutrient digestibility, plasma indices related to gut hormones and immunity, gut microbiota composition, and fermentation products in weaned pigs. A total of 60 weaned pigs were allocated to two dietary treatments, and piglets in each group received control (CON) diet or 5% CB diet for 28 days. Growth performance, nutrient digestibility, indices of gut hormones and immunity in plasma were evaluated. Microbiota composition in feces was determined using 16S rRNA amplicon sequencing, and fermentation products were measured by high-performance ion chromatography. The results showed that dietary CB did not affect growth performance, nutrient digestibility, gut hormones, or fermentation products in the trial (P > 0.05). There was an increased response to CB inclusion on interleukin-10 production (P < 0.05). On day 28, piglets fed dietary CB had a higher shannon index (P < 0.05). The population of the Firmicutes in CB treatment were decreased (P < 0.05), while the percentage of the Bacteroidetes were increased (P < 0.05). In particular, the populations of Eubacterium corprostanoligenes, Pevotella, and Fibrobacter related to polysaccharide fermentation of cereal bran were increased (P < 0.05). In conclusion, a post-weaning diet containing 5% CB increased intestinal microbial diversity, especially higher richness of fibrolytic bacteria, and promoted anti-inflammatory response to some extent in piglets, these changes should facilitate the adaptation of the digestive system of piglets in the subsequent growing phases.
