Title: Pituitary gonadotropins in the Japanese quail (Coturnix coturnix japonica) during photoperiodically induced gonadal growth
Abstract: The gonadotropin content of the anterior pituitary in Japanese quail (Coturnix coturnix japonica) was studied in relation to photoperiodically induced gonadal development. The content was low in birds held on short daily photoperiods and in which there was no gonadal development. Long daily photoperiods caused complete gonadal development and a steady increase in gonadotropin content during the first 21 days with a slight decline thereafter. The anterior pituitary gland increased in weight under a long daily photoperiod. The results are discussed with respect to the balance between hormone synthesis and hormone release.
