反刍动物饲料组合效应在养分吸收和能量利用上的研究进展

饲料间组合效应是指来自不同饲料来源的营养物质、非营养物质及抗营养物质间互作的整体效应。反刍动物饲料间的组合效应表现得更为突出和普遍。组合效应可能发生在消化和组织代谢2个层面上,但是由于组合效应的复杂性,目前的研究尚未形成系统的理论。本文综述了反刍动物饲料间组合效应的概念、发生,重点分析了组合效应发生时组织代谢层次上可吸收养分平衡性和能量利用的变化。

Advance in Association Effects of Feedstuffs on Nutrients Absorption and Energy Utilization in Ruminants

Associative effects of feeds are the whole interactive effects among the nutrients,non-nutrients and anti-nutrients from different feeds resources.Associative effects of feeds are apparent in ruminants when fed roughage.It mainly happens in the process of digestion and metabolism.Because of the complexity of associative effects,the system info has not been established yet.In this paper,the authors explained the concept of associative effects and focused on the changes of the balance among absorbed nutrients and utilization of energy when there exist associative effects.
