摘要
蛋白饲料来源短缺已成为影响饲料产业发展的问题之一。豆粕作为油脂工业的副产物,其产量大,价格便宜,营养价值高,是近年来主要蛋白饲料来源之一。但是豆粕中含有多种抗营养因子,必须去除。抗营养因子的去除方法有化学、物理、生物学等方法,其中生物学方法主要是通过微生物发酵来降解其中的抗营养因子,尤其以益生茵多茵混合发酵效果最好,不仅能有效去除抗营养因子,而且能将不易消化的蛋白质大分子降解成多肽、小肽乃至寡肽,益生菌本身的代谢产物还能增强免疫力和促进动物生长。
The shortage of protein feeds has become a bottleneck of the feed industry. Soybean meal is the by -product of edible oil processing, and its great annual output makes it one of the main protein feeds. The price of soybean meal is relatively low while its nutritive value is very high. However, there are several anti -nutrient factors in soybean meal, which should be removed before feeding. These anti - nutrient factors could be removed/destroyed chemically, physically or biologically. Biological removal/destroy of anti - nutrient factors is mainly achieved by fermentation with microbes, among which the probiotic microbes are preferred. Fermentation of soybean meal with probiotics could destroy those anti - nutrient factors, and more importantly, probiotics could degrade protein macromolecules into short peptides or even oligopeptides and therefore promote the nutrient value of soybean meal. The probiotics themselves and their metabolites are also very helpful to improve the immunity and healthy of the animals.
