[Growth, food utilization and protein content of some organs with varying zinc and nickel supplies. 1. Interactions between nickel and zinc].

In two-factorial experiment with variable Zn- and Ni-content of the diet effects of interactions between iron and zinc on growth, food intake, food efficiency and protein concentration is serum, liver and pancreas of rats were investigated through a wide range of supply of both elements. Besides food efficiency interactions between zinc and nickel influenced all parameters, if certain relations of the both elements were imbalanced. Especially by growth it could be shown that either zinc deficiency could be reduced by excessive Ni supply nor Ni toxicity by elevated Zn content of the diet.
