Abstract: The purpose of this study was to investigate the effects of zinc and vitamin B-6 supplementation on growth and mineral deposition of young rats fed various levels of protein. Dietary factors included three levels of protein (7.5, 15, and 30%), three levels of vitamin B-6 (1, 5, and 100 ppm), and three levels of zinc supplements (0, 50, and 100 ppm). Criteria used for evaluating animal responses to various test diets included weight gain, hemoglobin level, and copper, iron, and zinc deposition in the liver. Results indicated that the addition of 50 ppm of zinc to the diet resulted in significant increase (p < .01) in weight gain, regardless of dietary protein level or vitamin B-6 supplementation. Increase in weight gains associated with increases in protein level occurred only when the diet contained adequate zinc, while increases in weight gains associated with increases in vitamin B-6 occurred only when the level of protein was marginal to inadequate (7.5%). Increasing levels of dietary protein were associated with highly significant increases (p < .01) in hemoglobin concentrations, while increases in zinc supplements resulted in highly significant decreases ( p < .01) in hemoglobin levels.
