摘要
Nutritional quality of forages has direct influence on health and productivity of livestock. High crude protein (CP) in forages makes rumen microflora more active and increases the efficiency of livestock to digest and assimilate the nutrients. Feeding studies have revealed that the diets sufficient in protein quantity but deficient in protein quality have negative impact on animal growth and production. Anti-nutritive compounds often show ill effects on animal health by interfering directly or indirectly in utilization of available nutrients in forages. Leguminous forages have better nutritive profile than grasses, which is mainly attributed to high protein content, balanced amino acid profile and good proportion of minerals and vitamins. The knowledge about different nutritional as well as anti-nutritional constituents will provide better option for the selection of forages to prepare nutritious and wholesome diet for livestock.

饲料的营养质量对牲畜的健康和生产力有直接影响。草料中的高粗蛋白（CP）使瘤胃菌群更活跃，并提高牲畜消化和吸收养分的效率。喂养研究表明，蛋白质数量足以但缺乏蛋白质质量的饮食对动物的生长和生产产生负面影响。抗营养化合物通常通过直接或间接地干扰草料中可用的营养素来对动物健康表现出不良影响。豆科饲料比草具有更好的营养特征，这主要归因于高蛋白质含量，平衡的氨基酸剖面以及矿物质和维生素的比例。关于不同营养和抗营养成分的知识将为选择饲料准备牲畜的营养和健康饮食提供更好的选择。
