摘要
“大食物观”包含了饲料在内的粮食安全供给,我国饲料粮占粮食总量48.2%,其中蛋白质饲料资源短缺,对外依存度居高不下,给畜产品稳产保供、粮食安全带来隐患,制约着我国畜牧业的发展。牛羊等反刍动物产业既是重要的畜牧产业构成,也是民生产业,文章针对非蛋白氮、低蛋白日粮配制等技术在反刍动物营养与日粮中的应用以及蛋白替代策略进行论述,旨在为反刍动物养殖过程中开源节流、绿色可持续发展提供参考。
The"big food concept"includes the food security supply,including feed.China's feed grain accounts for 48.2%of the total grain,with a shortage of protein feed resources and high external dependence,which poses safety risks to the stable production and supply of livestock products and food,and restricts the development of China's animal husbandry.The ruminant animal industry,such as cattle and sheep,is not only an important component of the animal husbandry industry,but also a livelihood industry.This article focuses on the application of technologies such as non protein nitrogen and low protein diet formulation in ruminant nutrition and diet,as well as protein replacement strategies.The aim is to provide reference for the process of increasing resources,reducing costs,and promoting green and sustainable development in ruminant animal breeding.
