The objective of this study was to investigate the effects of fermented wheat bran (FWB) on growth performance, nutrient digestibility, serum biochemistry, short-chain fatty acids, and intestinal microbiota of weaned piglets. One hundred twenty-eight weaned piglets were randomly assigned to 4 groups, each with 8 pens and 4 piglets per pen: basal diet group (BD), 5% wheat bran group (5% WB), 5% fermented wheat bran group (5% FWB), and 10% fermented wheat bran group (10% FWB) for a 28-day trial. Results showed that compared to the BD group, the diarrhea rate in the 5% WB group was significantly increased ( p < 0.05) at d 15–28 and d 1–28. In contrast, at d 15–28 and d 1–28, the diarrhea rates in the 5% FWB and 10% FWB groups were significantly lower than those in the 5% WB group and showed no significant difference compared to the BD group. Moreover, the apparent total tract digestibility (ATTD) of DM, GE, CP, EE, CF and ADF at d 1–14, and EE and NDF at d 15–28 in the 5% FWB group were significantly improved compared to the 5% WB group ( p < 0.05). However, only the ATTD of CP, EE and CF at d 1–14 in the 10% FWB group were significantly higher than those in the 5% WB group ( p < 0.01). Compared to the BD group, the pH of cecum chyme and serum urea nitrogen content in the 5% FWB and 10% FWB groups were significantly reduced ( p < 0.05), and those in the 10% FWB group were significantly lower than those in the 5% WB group ( p < 0.01).
