The effect of estrogens on serum ferritin levels in duck

Abstract

Serum and tissue ferritin content is measured in duck by a RIA method before and after treatment with estrogens, as well as serum ferritin in laying and non-laying hen.Both serum ferritin and tissue ferritin decrease after treatment with estrogens, while serum iron increases.A relationship between serum ferritin and iron stores in duck is shown.
