THE HEXOSAMINE AND HYDROXYPROLINE CONTENTS OF THE OVIDUCTS OF THE ESTROGENIZED IMMATURE PULLET AND OF THE NORMAL LAYING HEN

Abstract

Estradiol benzoate, 1 mg per day, plus testosterone propionate, 1 mg per day, were administered to sexually immature pullets for 10 days. The dry matter, hexosamine, and hydroxyproline contents of the hypertrophied oviducts and of their major anatomical parts were in general similar to the corresponding data obtained for the oviducts of mature laying hens. Additional treatment with progesterone, 0.5 mg per day, did not affect in any definite way the weight and dry matter, hexosamine, or hydroxyproline contents of the hypertrophied oviducts of the immature pullets. Additional treatment with progesterone, 1.0 mg per day, significantly depressed the weight and dry matter contents of the hypertrophied oviducts and of their major anatomical parts, except for the vagina.
