The result showed:leptin level was positive related with the level of E2,P in mammary only duringthe pregnancy,leptin level was positive to the level of Prl GH during the pregnancy-lactation cycle Hint:leptin in mammary might promote the development of mammary duct and gland bubble with E2,P;leptin in mammary might promote the mammary development and start secretion of milk with Prl; leptin in mammary and GH were promoting the growth during mammary developmen,strengthen the action to promote the gland bubble development with Prl,mighe play an important role in the modulation of the mammary gland development.
