摘要
粗饲料作为反刍动物重要的能量来源,是反刍动物饲料中不可或缺的部分。粗饲料是反刍动物瘤胃微生物和宿主动物的重要营养来源,对提高反刍动物生产力和维持肠道健康有重要作用。反刍动物采食配合饲料后,各组分会在瘤胃中经短时间储存后被消化,各饲料原料在不同配比时的表观消化率与单个饲料表观消化率的代数和不相等,即各饲料之间产生组合效应。文章简要介绍组合效应的研究现状、概念、评价标准及其研究方法,重点阐述饲料组合效应的分类及其应用。文章为快速、准确评估反刍动物饲料间组合效应技术体系和科学指导反刍动物饲养搭配提供参考。
Roughage is an important energy source for ruminants and an indispensable part of ruminant feed.Roughage is also an important source of nutrition for rumen microorganisms and host animals,which plays an important role in improving ruminant productivity and maintaining intestinal health.After ruminants take food,each feed group will be briefly stored in the rumen for digestion,and the apparent digestibility of each feed component at different ratios is not equal to the algebraic sum of the apparent digestibility of a single feed,that is,associative effects is produced between each feed.The paper briefly introduces the research status,concept,evaluation criteria and research methods of associative effects,with emphasis on the classification and application of feed associative effects.The purpose of the study is to provide a reference for the rapid and accurate evaluation of the associative effect technical system of ruminant feed and the scientific guidance of ruminant feeding.
