- 中文摘要: The injection of prolactin induced broody behaviour, clucking, in all pseudo-hypophysectomized, hypophysectomized, and hypophyseal autotransplanted New Ham-pshire laying hens. The effect of prolactin in inducing broodiness is independent ofthe presence of pituitary gland and its“controlled”endocrine glands. The injectionof a small amount of progesterone could induce broody behaviour, clucking, inhypophysectomized hens, too. This situation suggests that the initiation of broodinessmight be a very complicated physiological phenomenon. The action of progesteronein chickens was fully discussed within the body of this paper.
