青贮饲料二次发酵及预防措施

Preventive Strategies of Secondary Fermentation of Silage

饲料青贮是保持饲料原有营养物质最有效的方法，青贮饲料可以最大限度地保持青绿饲料的营养物质不被破坏。但在生产中，青贮饲料二次发酵是个亟待解决的问题，它不仅使青贮饲料的养分损失，更严重的是因大量霉菌活动还可发生霉变，产生有害物质，毒害动物的健康，给饲料生产带来巨大的损失。文章就青贮饲料二次发酵的概念及原因进行了分析，同时对预防二次发酵的研究进展方面进行了总结，为今后青贮饲料生产过程中避免二次发酵提供参考。

Silage is one of the most effective ways to retain green forage nutrient. However, in practice, secondary fermentation is an important reason that makes the silage be low quality and contaminate by mold, In addition, the feed subjected to secondary fermentation also cause substantial damage to those raised animals.
