THE use of synthetic estrogens for the hormonal fattening of poultry, and studies designed to demonstrate whether or not estrogenic residues remain in the edible tissues of the treated poultry have recently been reviewed by Lorenz (1954) and by Merker et al. (1955). Commercial use of the estrogens has been limited to the implantation or injection of stilbestrol and to the oral feeding of dienestrol diacetate. The usual practice is to treat the birds at 7 to 9 weeks of age and to slaughter the birds 4 to 6 week later. With the development of a sensitive assay method (Umberger, Gass and Curtis, 1958) based on the work of Stob, Andrews and Zarrow (1954), an examination has been made of the edible tissues from chickens treated with various commercial preparations of stilbestrol. The results of these assays are the subject of this report. A subsequent report will detail the studies … |
