摘　　要：生物性添加剂能改善青贮饲料的青贮品质,提高青贮饲料的利用率,解决饲料供应不平衡问题,从而进一步推动畜牧业可持续发展。生物性添加剂主要包括微生物添加剂和酶制剂。如何发挥出生物性添加剂各自优点,形成协同作用,成为目前高效利用青贮饲料的关键。基于此,本文对目前国内外生物性添加剂在青贮饲料中的应用进行了分析归纳,总结了其对青贮饲料发酵品质、营养价值、有氧稳定性及动物生产性能的影响,提出了未来生物性添加剂应向复合生物性添加剂(菌种组合和菌酶组合)方向重点发展的观点,以期为研发出具备高效、环保、低成本等优势的新型复合生物性添加剂提供科学性依据。Biological additives can improve the silage quality of silage,increase the utilization rate of silage,and solve the problem of unbalanced feed supply,thus further promoting the sustainable development of animal husbandry.Biological additives mainly include microbial additives and enzymes.How to give full play to the respective advantages of biological additives and form a synergistic effect has become the key to the efficient utilization of silage.Based on this,this paper analyzes and summarizes the application of biological additives in silage at home and abroad,and summarizes their effects on the fermentation quality,nutritional value,aerobic stability and animal production performance of silage.Additives should focus on the development of compound biological additives(strain combination and bacterial enzyme combination),in order to provide a scientific basis for the development of new compound biological additives with high efficiency,environmental protection,low cost and other advantages.
