[Changes in zinc retention in pregnancy].

Enhanced retention of nutrients in the gravid organism, which exceeds the normal deposition in the reproductive organs and in fetuses, is called 'pregnancy anabolism'. For zinc this superretention could be established only in the liver which was enlarged in gravid rats, too. In all other tissues of gravid animals, zinc contents were lower compared with nongravid rats. After lactation, these changes in zinc status were equalized, and gravid and nongravid animals showed the same values.
