苦豆籽粕-两歧双歧杆菌-唾液乳杆菌合生元微胶囊的研制

以抑制仔猪致病性大肠埃希菌效果优异的猪源唾液乳杆菌(Lactobacillus salivarius)、两歧双歧杆菌(Bifidobacterium bifidum)为益生菌,苦豆籽粕为益生素,通过海藻酸钠-壳聚糖包被技术,将益生菌和益生素做成一个微胶囊整体,活菌数达到1.1×109 cfu/g,人工胃液和人工肠液处理后的活菌数为2.5×108 cfu/g。浸入5g/L壳聚糖溶液中常温保存,120d后活菌数为1.6×107 cfu/g。该结果为防治仔猪早期断奶腹泻、仔猪黄白痢提供了科学依据。

Devlopment of Foxtail-like Sophara Seed's Dregs-Bifidobacterium bifidum-Lactobacillus salivarius Synbiotics Micro-capsule

In this study,Bifidobacterium bifidum and Lactobacillus salivarius,which can inhibit piglet pathogenic Escherichia coli,were used as probiotics,while foxtail-like sophara seed’s dregs as prebiotics.By alginate-chitosan-coated technology,synbiotics micro-capsule was prepared.The number of viable germs reached 1.1×109 cfu/g.However,when stayed in artificial gastric fluid and artificial intestinal fluid for 2 hours,the number of viable germs reached 2.5×108 cfu/g.The number of viable germs reached 2.5 × 108 cfu/g when immersed in 5 g/L chitosan solution and stored at room temperature for 120 days later.Synbiotics micro-capsule may used for prevention and curing diarrhea of weaned piglets,yellow and white scours of piglets.
