Effect of conjugated linoleic acid supplementation on fat globule size in raw milk

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
