Evaluation of supplemental niacin for turkeys fed corn-soy diets from four to twelve weeks of age.
A corn-soy basal diet, which was calculated to contain 21 mg of niacin/kg diet, was used to investigate the niacin needs of turkey poults from 4 to 12 weeks of age. Poults had been fed a diet that contained 80.6 mg niacin/kg of feed until 4 weeks of age. Supplemental niacin was added at 0, 10, 20, and 50 mg/kg. There were no significant differences in mortality, leg disorders, or 12-week weight gains due to amount of niacin of the diet. These data indicate that 21 mg/kg niacin is adequate for optimum growth of turkeys from 4 to 12 weeks of age when they are fed a corn-soy diet.
