摘　　要：亚麻籽是提高乳中ω-3 UPFA(ω-3多不饱和脂肪酸)的常用饲料资源,而饲喂不同处理的亚麻籽对奶牛生产和乳中ω-3 UPFA影响均不相同,其中机械加工亚麻籽以其低成本处理和较高的乳中的转运效率引起人们的关注。文章综述了,添加不同剂量的机械加工亚麻籽对奶牛的生产性能、乳中脂肪酸组成、乳中ALA(α-亚麻酸,ω-3 UPFA的一种)含量,以及乳中ALA转运效率的影响。Flaxseed is a common feed source which can improve theω-3 UPFA(ω-3 polyunsaturated fat⁃ty acid)in milk.However,different influence on production performance and milk fatty acid were shown with suppling flaxseed in different treatment.Mechanical flaxseed supplementation showed lower cost and higher transfer efficiency of ALA in milk.This article reviewed the influence of production perfor⁃mance,fatty acid profile,the content of ALA(α-Linolenic acid;a kind ofω-3 UPFA)and the transfer efficiency of ALA in milk with mechanical flaxseed supplementation.
