Abstract The effect of conjugated linoleic acid (CLA) on milk lipids and on the size of milk fat globules (MFGs) during milk fat depression in dairy cows was evaluated. Twelve Holstein cows were randomly assigned to a control diet or control plus Ca-protected CLA at 15 g kg-1 dry matter for an 8-day period. Feeding CLA did not affect milk production, dry matter intake or lactose level, but tended to reduced milk protein (–0.19%; P = 0.08) and reduced milk fat content (–1.39%; P

添加共轭亚油酸对生乳脂肪球大小的影响

摘要 评估了共轭亚油酸 (CLA) 对奶牛乳脂抑制期间乳脂和乳脂球 (MFG) 大小的影响。12 头荷斯坦奶牛被随机分配到对照日粮或对照加钙保护的 CLA 中，干物质为 15 g kg-1，为期 8 天。饲喂 CLA 不影响产奶量、干物质摄入量或乳糖水平，但倾向于降低乳蛋白 (–0.19%; P = 0.08) 和降低乳脂含量 (–1.39%; P
