Abstract

The purpose of this study was to examine the fermentation of A. membranaceus by L. plantarum and its effects on broiler chickens. L. plantarum solid-state fermentation was employed to solve the problem of releasing the active components of A. membranaceus. The effect of L. plantarum on astragalus was examined by measuring the contents of protein, carbohydrate, calycoflavone, and formononetin in A. membranaceus before and after fermentation. The effect of A. membranaceus on L. plantarum was demonstrated by detecting the changes in galactosidase in L. plantarum before and after fermentation. Fermented A. membranaceus was fed to broiler chickens, and the indices of growth performance, antioxidants, immune function, and intestinal short-chain fatty acids were recorded. The results showed that the cellulose and pectin on the surface of A. membranaceus were decomposed by L. plantarum solid-state fermentation, and the macromolecular proteins were degraded into small molecules. A. membranaceus increased the content of galactosidase in L. plantarum. Solid-state fermentation increased the contents of functional sugars, calycosin, and formononetin in A. membranaceus. Fermentation of A. membranaceus significantly improved the production performance of broilers as well as the antioxidant index, immune index, intestinal morphology, and intestinal short-chain fatty acid content.

植物乳杆菌在肉鸡饲料黄芪固态发酵中的作用。

本试验旨在研究植物乳杆菌对肉仔鸡膜芽孢杆菌的发酵及其对肉仔鸡的影响。采用植物乳杆菌固态发酵的方法，解决了黄芪有效成分的释放问题。通过测定发酵前后黄芪中蛋白质、碳水化合物、花萼黄酮和刺芒柄花素的含量，探讨了植物乳杆菌对黄芪的影响。通过检测发酵前后植物乳杆菌中半乳糖苷酶的变化，证实了膜芽孢杆菌对植物乳杆菌的影响。将发酵后的膜芽胞杆菌饲喂肉鸡，观察其生长性能、抗氧化剂、免疫功能和肠道短链脂肪酸等指标。结果表明，植物乳杆菌固态发酵对膜拟南芥表面的纤维素和果胶进行了分解，大分子蛋白质被降解为小分子。黄芪提高了植物半乳糖苷酶的含量。固态发酵提高了黄芪中功能糖、毛蕊花素和刺芒柄花素的含量。发酵膜芽孢杆菌可显著提高肉仔鸡的生产性能、抗氧化指数、免疫指数、肠道形态和肠道短链脂肪酸含量。
