Effects of feeding increasing dietary concentrations of fat on the performance of lactating dairy cows

In experiment 1 treatments were: control, no fat; control, 3% calcium salts of long-chain fatty acids (Ca-LCFA); control, 6% Ca-LCFA; and control, 9% Ca-LCFA. Dry matter intake and production of milk, milk protein, and solids-not-fat (SNF) were not altered greatly by feeding up to 6% Ca-LCFA in the diet. Nutrient utilization was optimized when between 3 and 6% Ca-LCFA were added to the diet; however, calcium digestibility was linearly decreased by feeding Ca-LCFA. Ca-LCFA may be fed to supply up to 6% of the dietary dry matter (DM) without having deleterious effects on ruminal fermentation and nutrient utilization.
