Supplementation of Dairy Cow Diets with Calcium Salts of Long-Chain Fatty Acids and Nicotinic Acid in Early Lactation

Forty multiparous Holstein cows were assigned to one of four treatments 15 d postpartum according to milk yield during wk 2 postpartum to examine the effects of supplementing niacin, Ca salts of long-chain fatty acids, and their interaction. Treatments were control, niacin (12 g/d), Ca salts of long-chain fatty acids (3% of dietary DM), or a combination of niacin and Ca salts. On d 99 postpartum, all cows were fed the control treatment for 2 wk to evaluate residual effects. Milk and FCM yields, blood plasma NEFA and ß-hydroxybutyrate concentrations, and apparent total tract hemicellulose digestibility were increased; milk protein percentage, milk SNF percentage, and blood plasma glucose concentrations were reduced by treatments containing the Ca soaps. Niacin supplementation increased milk protein content and yield but reduced blood plasma ß-hydroxybutyrate concentration. During the residual period, in which all cows received the control treatment, milk yield and plasma NEFA concentration remained elevated, milk protein and SNF contents remained depressed, and milk fat content was reduced for cows previously supplemented with Ca salts of long-chain fatty acids. Methionine and phenylalanine uptakes by the mammary gland were enhanced by niacin supplementation. Results indicated that dairy cattle in early lactation yielded more milk when their diets were supplemented with Ca salts of long-chain fatty acids and that niacin supplementation increased milk protein content and yield.
