寡聚糖一般不能被单胃动物自身分泌的消化酶消化,但能被消化道后部微生物产生的酶分解。研究表明:寡聚糖具有优化肠道微生态区系、阻止病原菌与肠粘膜结合及增强宿主免疫力的作用。在水产动物上,寡聚糖可以促进生长,提高成活率,改善饲料利用率,其应用会越来越广泛。 Oligosaccharides generally can not be digested by digestive enzymes secreted by the monogastric animals themselves, but can be broken down by enzymes produced by microorganisms in the back of the digestive tract. Studies have shown that: oligosaccharides with gut microflora optimization, to prevent the binding of pathogens and intestinal mucosa and enhance host immune function. In aquatic animals, oligosaccharides can promote growth, improve survival rate, improve feed utilization, its application will be more extensive.
