防止青贮饲料中存留有害微生物的工艺与策略

摘要

Ensiling is a method for preserving moist crops based on organic acid production by lactic acid bacteria under anaerobic conditions. However, silage can be a vector for undesirable microorganisms, impairing crop preservation, animal performance or the health of both animals and humans.To improve silage preservation and guarantee the quality of this animal feed, silage additives such as chemicals, enzymes and bacterial agents can be employed. The purpose of the present paper is to review existing information on the desirable and undesirable microorganisms involved in silage processing, and provide possible methods for farmer.%青贮是基于乳酸菌在无氧条件下产生的有机酸来保存高水分农作物的一种方法.然而,青贮饲料也可以作为有害微生物的载体,损害农作物的保存、动物的生产性能,以及动物和人类的健康.为了提高青贮饲料的保存期和品质,一些化学类、酶类以及菌类青贮添加剂被应用到青贮加工过程中.本文的目的是回顾存在于青贮加工过程中的有益和有害微生物,介绍了防止青贮饲料中存留有害微生物的工艺与策略,以便为青贮饲料的生产质量管理提供参考依据.
