摘　　要：早期断奶仔猪具有快速生长和较强蛋白质沉积能力,对蛋白质营养需要量高。饲粮蛋白质水平对断奶仔猪生长性能、肠道健康、营养物质消化吸收代谢及体蛋白质沉积具有深远影响,是断奶仔猪发挥生长潜力的关键因素。本文主要综述饲粮蛋白质水平对断奶仔猪生长性能、肠道健康、营养物质消化吸收以及体蛋白质沉积的影响,早期断奶仔猪蛋白质需要量标准及影响断奶仔猪蛋白质需要量的因素,以期在饲料禁抗及铜、锌限量添加的情况下,为断奶仔猪蛋白质营养需要量研究提供一定理论基础。Early weaned piglets grow fast and have strong protein deposition ability,so they have high protein requirements.Dietary protein level has a profound effect on the growth performance,intestinal health,nutrient digestion,absorption and metabolism,and body protein deposition of weaned piglets,so it is a key factor for weaned piglets to develop their growth potential.Meanwhile,the protein requirement of weaned piglets is affected by their basic intestinal health,dietary amino acid balance and energy intake.This review summarizes the effect of dietary protein level on the production performance,the protein requirement standard and the factors affecting the protein requirement of weaned piglets.We tend to provide a theoretical basis for the study of protein nutritional requirement of weaned piglets under the condition of feed antibiotics prohibition and limited addition of copper and zinc.
