The severe malformations shown in the right chick embryo are the result of zinc deficiency in the diet of the hen that laid the egg. On the left is a normal embryo. Zinc deficiency of the mother produces specific lesions in the developing embryo that are more severe earlier in gestation. The most serious lesions alter the differentiation of the nervous system and the mesoderm, which is the germ layer that forms many muscles, the circulatory and excretory systems, and the dermis, skeleton, and other supportive and connective tissue.
