Effect of Feeding Three Levels of Riboflavin, Niacin and Vitamin B 6 to Male Chickens on the Nutrient Composition of Broiler Breast Meat

Sixty day‐old male chicks were fed three rations differing in riboflavin (R), vitamin B 6 , and niacin (N) content. The three rations were: (1) an adjusted basal ration containing R, B 6 and N 10% above National. Research Council recommendations, (2) a ration containing 75% of the 3 vitamins as in (1), and (3) with 125% of the 3 vitamins as in (1). Birds were grown for 51 days and the breast meat harvested and analyzed for proximate composition, 3 vitamins and 9 minerals. No significant differences in the nutrient content of meat were found attributable to the dietary treatments. Results indicated that broiler meat composition was fairly constant even though birds consumed wide differences in R, B 6 and N.
