摘　　要：粗饲料是牛日粮的重要组成部分,其品质对牛生产性能和健康有极大影响,而实际生产中往往做不到对其品质准确评价甚至忽略,进而影响养殖的经济效益。现有粗饲料品质评价指标有单项指标和综合指标,单项指标主要包括常规营养成分、干物质随意采食量、消化率等,综合指标则包括粗饲料相对值、品质指数、粗饲料相对品质指数、粗饲料分级指数等。现综述国内外现有评价粗饲料品质指标的研究进展,以期为研究人员进行牛粗饲料评价提供参考。As an important part of cattle diet,the quality of coarse fodder has great impacts on the growth performance and health of cattle.However,the exact quality evaluation of coarse fodder can not be accomplished or even ignored in the cattle rearing,thereby cattle feeding are affected.The general nutrient,voluntary dry matter intake,digestibility as single indices and relative feed value,quality index,relative forage quality and forage grading index as integrative indexes are used to evaluate the quality of coarse fodder.This paper reviewed the progress in the evaluation of quality indexes on coarse fodder to provide reference for the domestic researchers.
