Abstract
The growth and differentiation of chick oviducts were caused by daily diethylstilboestrol (DES) or oestradiol-17 beta (E2) injections, and the effects of these oestrogens on the progesterone-induced production of a biotin-binding egg-white protein (avidin) were studied. In the DES primed oviducts, but not in the E2 primed ones, both DES and E2 administered with progesterone potentiated avidin production 2 to 3-fold, even after 10-day oestrogen withdrawal. The results suggest that DES and E2 prime the avian reproductive target tissue differently.
