Weight gains of young broiler chicks were not reduced by up to 2400 ppm added zinc fed to four weeks of age. Tissue zinc was not changed significantly by 600 or 1200 ppm supplement dietary zinc, but at 2400 ppm added zinc, blood, kidney, and liver zinc were significantly elevated (P < 0.05). In the heart, zinc was not affected by the added dietary zinc but increased over time with all diets. Unlike the calf weanling pig, the metabolism of zinc in the young chick does not appear to change appreciably with increasing maturity. Thus, the homeostatic control mechanisms of the young chick are effective for up to 1200 ppm dietary zinc, but are partially overcome by 2400 ppm added dietary zinc. 17 references, 1 figure, 2 tables.
