Abstract The present study was performed to investigate whether dietary fermented soybean meal (FSBM) inclusion could improve growth performance and ameliorate diarrhea via improving ileal barrier function in weaned piglets challenged by enterotoxigenic Escherichia coli (ETEC) K88, and further analyze the potential roles for inflammatory response and epithelium apoptosis. A total of 32 crossbred barrows (Duroc × Landrace × Large White), 21 ± 2 day of age, and initial body weight of 6.86 ± 0.54 kg) were assigned to 2 diets (basal diet with or without FSBM, 60 g/kg at the expense of soybean meal) and subsequently challenged or not with ETEC K88 (5 × 1010 CFU/piglets) on day 15 of experiment in a 2 × 2 factorial arrangement of treatments. The results showed that weaned piglets fed FSBM had a tendency for greater average daily gain (ADG) compared to piglets fed SBM during day 1–14 (P = 0.081). After ETEC K88 challenge, the challenged piglets had higher (P

日粮发酵豆粕可改善产肠毒素大肠杆菌 K88 攻击的断奶仔猪的生长性能和回肠屏障功能

摘要 本研究旨在探讨日粮发酵豆粕 (FSBM) 是否可以通过改善受产肠毒素大肠杆菌 (ETEC) K88 攻击的断奶仔猪的回肠屏障功能来改善生长性能和改善腹泻，并进一步分析其对炎症的潜在作用。反应和上皮细胞凋亡。总共 32 头杂交猪（杜洛克 × 长白 × 大白），21 ± 2 日龄，初始体重为 6.86 ± 0.54 kg）被分配到 2 种饮食（含或不含 FSBM 的基础饮食，60 g/kg）豆粕的费用），随后在试验的第 15 天以 2 × 2 的因子处理安排是否接受 ETEC K88（5 × 1010 CFU/仔猪）攻击。结果表明，与饲喂 SBM 的仔猪相比，饲喂 FSBM 的断奶仔猪在第 1-14 天具有更高的平均日增重 (ADG) 趋势（P = 0.081）。ETEC K88攻击后，攻击的仔猪有更高的（P
