摘要
我国是饲料生产大国,配合饲料产量位居世界第一,但豆粕等重要的蛋白质饲料原料在很大程度上依赖于进口,所以开发可替代豆粕的高品质蛋白质饲料原料尤为重要.我国棉花资源丰富,棉花加工过程中的副产物棉籽粕富含蛋白质和氨基酸,由棉籽粕进一步加工处理得到的棉籽蛋白,粗蛋白质含量高、氨基酸较平衡,可以在一定程度上替代豆粕和降低饲料成本.本文总结了棉籽蛋白的分类、加工工艺、营养成分、猪的有效能和氨基酸消化率及其在猪生产中的应用研究,可为棉籽蛋白的深层次开发和高效利用提供参考.
Abstract
China is a major player in feed production,ranking first in the world.However,key protein ingredi-ents such as soybeans heavily rely on imports.Therefore,it is particularly crucial to research and develop high-quality protein materials that can replace soybean meal.China has an abundant supply of cotton resources.The byproduct of cotton processing,cottonseed meal,is rich in proteins and amino acids.Further processed cotton-seed protein,with its high crude protein content,rich nutrition,and wide availability,can partially replace soybean meal and reduce feed costs.This article summarizes the classification,processing techniques,nutri-tional values,available energy,and amino acid digestibility of cottonseed protein,which can provide refer-ences for the further development and efficient use of cottonseed protein.[Chinese Journal of Animal Nutri-tion,2024,36(4):2175-2187]
