目的：评估发酵大豆对断奶仔猪的抗腹泻和促进生长的特性。方法和结果：在第一阶段仔猪日粮中，用煮熟的大豆或根霉小孢子菌或枯草芽孢杆菌发酵大豆代替烤全脂大豆（20%）。确定了对产肠毒素大肠杆菌 (ETEC) 攻击的断奶仔猪腹泻的发生率、严重程度和持续时间的影响（围栏试验，每次治疗 24 头仔猪）。与含有烤大豆的对照饮食相比，含有根霉发酵大豆的饮食中腹泻的严重程度显着减轻。饲喂发酵大豆的仔猪表现出采食量增加（13% 和 12%）、平均日增重（18% 和 21%）以及饲料效率（3% 和 8%）（分别针对根霉菌和芽孢杆菌发酵大豆）。然而，在治疗组中，观察到了不同的死亡率和受体阳性仔猪的潜在分布不均。结论：煮熟并发酵的大豆可能有利于控制 ETEC 挑战的断奶仔猪（特别是根霉发酵）的腹泻，并显着提高体重增加和采食量（特别是芽孢杆菌发酵）。研究的意义和影响：发酵大豆可以在控制腹泻和饲料方面提供益处仔猪的效率。
Aims: To evaluate anti-diarrhoeal and growth enhancing properties of fermented soya beans in weaned piglets.Methods and Results: In a first phase piglet diet, toasted full-fat soya beans (20%) were replaced with either cooked soya beans or Rhizopus microsporus or Bacillus subtilis fermented soya beans. The effect on the incidence, severity and duration of diarrhoea in enterotoxigenic Escherichia coli (ETEC)-challenged weaned piglets was determined (pen trial, 24 piglets per treatment). Severity of diarrhoea was significantly less on the diet with Rhizopus -fermented soya beans compared with the control diet containing toasted soya beans. Piglets fed fermented soya beans showed increased feed intake (13 and 12%), average daily weight gain (18 and 21%) and feed efficiency (3 and 8%) (for Rhizopus and Bacillus -fermented soya beans, respectively). However, in the treatment groups an unequal mortality and a potential unequal distribution of receptor-positive piglets were observed.Conclusions: Cooked and fermented soya beans could be beneficial in the control of diarrhoea in ETEC-challenged weaned piglets (particularly Rhizopus fermented) and significantly improved weight gain and feed intake (particularly Bacillus fermented).Significance and Impact of the Study: Fermented soya beans could offer benefits with respect to the control of diarrhoea and feed efficiency in piglets.
