Abstract

There is growing interest among nutritionists in feeding reduced protein diets to broiler chickens. Although nearly a century of research has been conducted providing biochemical insights on the impact of reduced protein diets for broilers, practical limitation still exists. The present review was written to provide insights on further reducing dietary protein in broilers. To construct this review, eighty-nine peer reviewed manuscripts in the area of amino acid nutrition in poultry were critiqued. Hence, nutritional research areas of low protein diets, threonine, glycine, valine, isoleucine, leucine, phenylalanine, histidine, and glutamine have been assessed and combined in this text, thus providing concepts into reduced protein diets for broilers. In addition, linkages between the cited work and least cost formation ingredient and nutrient matrix considerations are provided. In conclusion, practical applications in feeding reduced protein diets to broilers are advancing, but more work is warranted.

摘要

营养学家对给肉鸡饲喂低蛋白日粮的兴趣日益浓厚。尽管已经进行了近一个世纪的研究,以提供关于低蛋白日粮对肉鸡影响的生化见解,但实际限制仍然存在。本综述旨在提供关于进一步降低肉鸡日粮蛋白质含量的见解。为撰写本综述,对家禽氨基酸营养领域的89篇同行评议手稿进行了评判。因此,本文对低蛋白日粮、苏氨酸、甘氨酸、缬氨酸、异亮氨酸、亮氨酸、苯丙氨酸、组氨酸和谷氨酰胺等营养研究领域进行了评估和整合,从而为肉鸡低蛋白日粮提供了相关概念。此外,还提供了引用文献与最低成本配方成分和营养基质考量之间的联系。总之,给肉鸡饲喂低蛋白日粮的实际应用正在推进,但仍需要开展更多工作。
