摘要
本文综述了断奶仔猪日粮蛋白质需要量及其影响因素，同时，从蛋白质营养不良对仔猪肠道结构和功能、体蛋白代谢和合咸以及低蛋白日粮的益处等方面探讨了低蛋白质日粮对仔猪的影响。结果表明：断奶仔猪（５～２０ｋｇ体重）日粮蛋白质需要量受品种、性别、饲养水平、饲粮类型和日粮能量浓度等因素影响，应视情况而定。另外，低蛋白日粮对仔猪肠道结构和功能、体蛋白代谢和合成都有一定影响，但适当降低日粮蛋白质水平有利于防治仟猪断奶后腹泻和消化不良。
Dietary protein requirement and its effect factors in weaning pigs are reviewed here. At the same time, effect of low protein level on gut structure and function, plasma protein and tissue protein synthesis and nitrogen metabolism and profit of low protein diet in piglet also reviewed. The result showed that variety, gender, feeding level, diet type and energy concentration and so on can affect dietary protein requirement in piglet. There is bad effect of low protein level on gut structure and function, plasma protein and tissue protein synthesis, but decreasing protein level properly is in favor of preventing piglet from diarrhea and dysfunction of digestion.
