摘　　要：青贮是调节反刍动物青饲料盈缺平衡、保存青饲料及减少贮藏过程中营养损耗的最佳方式。青贮饲料在生产和使用过程中,会受到多种霉菌毒素污染。青贮饲料中的霉菌毒素会对反刍动物的生产性能和健康产生不利影响,并危害人类健康。因此,有必要在青贮过程中选择合适的添加剂。目前,由于地衣芽孢杆菌具有提供优异特性功能性酶、益生菌功能以及生物脱氮、改善畜禽肠道健康和调节免疫力等生物学潜力,已被用于现代和可持续的农业系统中,但其作为青贮添加剂的应用甚少。因此,本文着重从地衣芽孢杆菌改善青贮发酵、抑制微生物腐败和霉菌毒素产生的潜在途径等方面进行综述,并提出未来的研究重点是关注地衣芽孢杆菌的特性和作用机制,以更好地实现其作为青贮饲料添加剂的潜在应用。Silage is the best method for regulating the balance of green forage for ruminant animals,preserving green forage,and reducing nutrient losses during storage.During the production and utilization of silage feed,contamination by various mycotoxins is a common issue.Mycotoxins in silage can negatively impact the performance and health of ruminant animals while also posing a risk to human health.Therefore,it is necessary to select suitable additives during the silage process.Currently,Bacillus licheniformis have been utilized in modern and sustainable agricultural systems due to their excellent functional enzymatic properties,probiotic functions,biological denitrification,improvement of animal gut health,and immune regulation.However,their application as silage additives is limited.Therefore,this article focused on reviewing the potential pathways of Bacillus licheniformis in improving silage fermentation,inhibiting microbial spoilage,and mycotoxin production,and it was suggested that future research should concentrate on the characteristics and mechanisms of Bacillus licheniformis to better realize their potential application as silage additives.
