This indicates that the regulatory role of hormones can have primary importance in the earliest phase of lactation, when metabolic processes are on the very brink of a ketotic state. That is why it is believed that, in conditions of a great burdening of the metabolism, inadequate activity by...
The main role ofestrogenic hormonesin the female body is to stimulate the growth and development of sexual characteristics and reproduction. Essentially,natural estrogenis responsible for the changes in breasts during adolescence and pregnancy including the development of milk ducts for lactation, and for...

The research described was designed to study the relative contributions of the process of milk synthesis, the suckling stimulus, and the hormones of lactation to the hyperphagia and body weight gain occurring during lactation. In the first set of studies the role of the suckling stimulus was consi...

The Mechanisms of Hormone Action from Chapter 21 / Lesson 14 15K When the glands in the endocrine system receive signals that something in the body is abnormal, they excrete hormones, which in turn send messages to other cells in the body. Learn about hormones, their activation, their tran...
Insulin-like growth factor (IGF)-I is thought to mediate a portion of the effects of bST on lactation in dairy cows. Serum concentrations of IGF-I are increased in lactating cows that were treated with bST, and IGF-I receptors are present in bovine mammary tissue. In addition, close arter...

It is unequivocal that prolactin is a most important hormone in experimental mammary tumorigenesis. Besides prolactin acts directly on mammary glands, recent studies have evidenced that the hormone also participates in mammary tumor virus production and
