Abstract
Traditional protein sources including soybean meal and fish meal face multiple challenges in terms of resources,costs,and environment,which has driven the transformation of studying poultry nutrition to-ward sustainability.This article systematically reviewed the nutritional value and functional properties of new alternative protein sources including insect protein,microalgae,and unconventional plant-based proteins,with a focus on exploring the effects of low-protein diets on the production performance,intestinal health,and im-mune function of poultry.It was found that moderately reducing the content of crude protein in feed under the premise of balancing amino acid can maintain the normal production performance and health condition of the body,while effectively reducing the excretion of nitrogen and lowering costs of feed.It will provide a theoreti-cal reference for the sustainable development and the optimization of nutrition in feed for poultry.关键词
