Abstract

Eight multiparous Holstein Dairy Cows were utilized in balanced change over design (2x2) in four periods of 21 days to examine the effects of supplementation niacin, CA SALTS OF LONG-CHAIN FATTY ACIDS and their interaction. Treatments were control (no supplements), CA SALTS OF LONG-CHAIN FATTY ACIDS (3% of dietary DM without niacin), niacin (12 g/d without CA SALTS OF LONG-CHAIN FATTY ACIDS), and a combination of niacin and CA SALTS OF LONG-CHAIN FATTY ACIDS. Each period of experiments included 2 weeks for adaptation to diets and one week for sampling and taking records. Cows were fed as TMR. The results showed that average milk and 4% FCM yields, milk lactose percentage, milk SNF percentage, total solid milk percentage and urea were not affected by CA SALTS OF LONG-CHAIN FATTY ACIDS and niacin levels (P>0.05). Dry matter intake, milk fat percentage and milk protein percentage in cows fed by diet with 0 and 3 percent fat prouder were 24.63 and 24.44 Kg, 3.08 and 3.54 percent, 3.22 and 2.99 percent respectively, that were significant differences between the both levels fat powders in these regards (P<0.05). Percentage of milk protein in cows fed 0 and 12gr niacin were 3.01 and 3.20 respectively that difference was not significant (P>0.05). Concentration of triglyceride was increased in treatment containing the CA SALTS OF LONG-CHAIN FATTY ACIDS (3% of dietary DM) (P<0.05). Concentration of glucose was elevated in treatment containing the niacin (12 g/d) (P<0.05). In general the results showed that using diet with 3% fat protein and 12gr niacin can be useful in DAIRY CATTLE.
