肉鸭饲粮豆粕减量替代营养调控技术研究进展OA

The meat duck industry has a high demand for protein feed resources,with soybean meal serving as the primary protein source.Its heavy reliance on imports has become one of the key constraints on the sustainable development of the duck industry.In this context,the implementation of soybean meal reduction and substitution strategies in duck diets,together with precision nutrition regulation,is an important technical approach to ensuring feed security,reducing production costs,and minimizing environmental impacts.This review systematically summarizes the precise nutritional requirements of ducks,nutrient interaction effects,principles and application techniques for formulating low-protein diets,as well as the development and efficient utilization of unconventional feed resources.It provides a theoretical foundation for the integrated application and industry promotion of soybean meal reduction substitution technology in duck feed.Future research should focus on optimizing nutritional parameters under different farming models and breeds,exploring the effects of diversified raw material combinations,and evaluating their long-term impacts on product quality and the environment,in order to promote the standardized,scaled,and sustainable application of soybean meal reduction substitution technology in the duck industry.
