In order to increase nutritive values of soybean meal (SBM), 3 species of microbes were used to ferment SBM. Through a 3 × 3 orthogonal design and parameter measurements of soybean peptide and anti-nutritional factor contents in the fermented soybean meal (FSBM), it was estimated that the best microbial proportion of Bacillus subtilis, Hansenula anomala and Lactobacillus casei was 2:1:2 for SBM fermentation (P < 0.05). The further piglet feeding experiment showed that 10% FSBM substitute for SBM had no significant effect on growth performance of suckling piglets (d 7-28) (P > 0.05). However, newly-weaned piglets (d 28-38) fed 10% FSBM and different levels of plasma protein obtained higher average daily gain (ADG) and feed conversion ratio (FCR), compared with those without FSBM but with 6% plasma protein (P < 0.05). Piglets (d 38-68) fed diets supplemented with FSBM and soybean protein concentrate (SBPC) at 3.75% and 7.5% respectively increased nutrient digestibility, fecal enzyme activity and lactic acid bacteria counts, and decreased fecal Escherichia coli counts (P < 0.05), compared with the control. These data indicated that FSBM had positive effects on nutrient digestibility and fecal microflora for piglets.

发酵豆粕可改善仔猪的生长性能、营养物质消化率和微生物菌群。


为了提高豆粕 （SBM） 的营养价值，使用 3 种微生物来发酵 SBM。通过对发酵豆粕 （FSBM） 中大豆肽和抗营养因子含量的 3 × 3 正交设计和参数测量，估计 SBM 发酵中枯草芽孢杆菌、异常汉森菌和干酪乳杆菌的最佳微生物比例为 2：1：2（P < 0.05）。进一步的仔猪饲喂实验表明，10% FSBM 替代 SBM 对哺乳仔猪的生长性能没有显著影响 （d 7-28） （P > 0.05）。然而，与没有FSBM但血浆蛋白为6%的仔猪相比，饲喂10%FSBM和不同水平血浆蛋白的新断奶仔猪（28-38岁）获得了更高的平均日增重（ADG）和饲料转化率（FCR）（P < 0.05）。与对照相比，饲喂添加 3.75% 和 7.5% FSBM 和大豆浓缩蛋白 （SBPC） 的仔猪 （38-68 日） 日粮提高了营养物质消化率、粪便酶活性和乳酸菌计数，降低了粪便大肠杆菌计数 （P < 0.05）。这些数据表明，FSBM 对仔猪的营养消化率和粪便菌群有积极影响。
