Abstract: This study investigated the effects of biotin, vitamin B-6, and zinc supplements on growth of and trace mineral deposition in young male rats. The animals were kept on experiment for 4 weeks and had free access to food and water while on experiment. Two levels of protein (15% and 30%) were used to provide diets with adequate and excess protein. Supplements to these basic diets included 2 levels of biotin (0 ppm and 4 ppm), 2 levels of zinc (0 ppm and 50 ppm), and 3 levels of vitamin B-6 (0 ppm, 50 ppm, and 100 ppm). Criteria used to evaluate the responses of animals to the dietary treatments included weight gain, and liver copper, iron, and zinc deposition. Analyses of variance indicated that growth was significantly increased when the diets were supplemented with zinc, vitamin B-6, and biotin. Maximum growth was observed in rats fed diets containing 4 ppm of biotin, 50 ppm of vitamin B-6, and 50 ppm of zinc.
