Influence of Feed Components in Semisynthetic Diets on Cadmium Retention in Chicks
The finding that certain substances in the diet as well as the nutritional status can increase Cd toxicity in man suggests that interactions between Cd and food components play a major role. We recently studied the influence of calcium (Winkler et al. 1984), zinc (Bundscherer et al. 1985) and other components on cadmium absorption and retention in growing chicks. Furthermore we investigated the effect of different binding forms, especially Cd-phytate, on the bioavailability of this heavy metal (Jackl et al. 1985, Rambeck et al. 1987). The present studies were undertaken to study the effects of varying contents of fiber, protein, fat and phytate on renal Cd-retention in growing chicks.
