摘要

饲粮有效纤维在反刍动物的消化活动中发挥着重要作用,对稳定瘤胃内环境、保证瘤胃健康和动物高产具有重要意义。但目前对反刍动物饲粮有效纤维的推荐量和推荐形式并不明确。本文拟从纤维物理有效性评价体系、有效纤维需要量评价方法及推荐形式等方面进行总结,系统比较宾州筛体系和咀嚼指数体系的差异,为生产中合理应用不同体系提供理论参考。

Abstract

Dietary effective fiber plays some important roles in regulating degradation in ruminants, keeping stability of internal environment and health of rumen, and supporting higher productivity. However, the requirement and the recommend form of effective fiber for ruminants were not clear. In this review, we summarized the current evaluation systems for the fiber physical effectiveness, evaluation methods and recommended form of effective fiber, etc., and compared the difference of Pennsylvania screening and chewing systems, which intended to provide reliable data for the application of different systems in production.
