益生菌在肉羊高效生产中的应用研究进展

Research progress in application of probiotics in efficient production of mutton sheep

益生菌主要通过增强机体免疫力、促进营养物质消化吸收、调节肠道微生态平衡及改善肠道屏障等方式促进动物生长。近年来,随着饲料端全面禁抗政策的实施,市场急需绿色、安全且促生长的饲料添加剂。由于益生菌具有无药物残留、非致病性和低成本等特点,作为替代抗生素的新型饲料添加剂广泛应用于肉羊生产中。饲粮中添加益生菌能够促进肉羊的生长发育,改善羊肉品质,提高抗氧化功能和免疫功能,有效提高了肉羊产业的养殖效率和经济效益。文章就益生菌作用机制及其在肉羊生长性能、营养物质表观消化率、产肉性能及免疫功能中的应用效果进行论述,旨在为益生菌在肉羊养殖相关领域中的合理应用提供参考。

Probiotics promote animal growth mainly by enhancing immunity,promoting digestion and absorption of nutrients,regulating intestinal microecological balance and improving intestinal barrier.In recent years,with the implementation of the total ban on feed,the market is in urgent need of green,safe and growth-promoting feed additives.Probiotics are widely used in mutton sheep production as a new feed additive to replace antibiotics because of their characteristics of no drug residue,non-pathogenic and low cost.Adding probiotics to the diet can promote the growth and development of mutton sheep,improve the quality of mutton,improve the antioxidant function and immune function,effectively improve the breeding efficiency and economic benefits of mutton sheep industry,and play an important role in the efficient production process of mutton sheep.This paper comprehensively discusses the mechanism of action of probiotics and their application effect on growth performance,apparent nutrient digestibility,meat production performance and immune function of mutton sheep production,aiming to provide reference for the rational application and development of probiotics in mutton sheep production.
