In order to study the expression of Gonadotropin-Releasing Hormone (GnRH) in the hypothalamus of estrus milk goat. Immunohisto chemical streptavidin-peroxidase stain technique was used in the present study. The results showed that immunochemistry positive reacting cells of GnRH was mainly localized in supraopticus nucleus, preopticus medialis nucleus, preopticus lateralis nucleus, suprachiasmaticus nucleus, area lateralis hypothalami, paraventricularis posterior nucleus, arcuatus nucleus, ventrolateralis nucleus, mamillaris lateralis nucleus, tubero mamillaris nucleus. This suggests that GnRH-containing neurons were widely distributed in hypothalamus of estrus milk goat.
