A cow’s milk production is controlled by a complex interaction of hormones. These hormones are produced by the cow’s pituitary gland thyroid gland adrenal glands and ovaries. The most important hormone involved in milk production is prolactin.
Prolactin is secreted by the pituitary gland and is responsible for the development of the mammary gland and the stimulation of milk production. Other hormones that play a role in milk production include growth hormone insulin and cortisol.
The mammary gland is a complex organ that is composed of several different types of cells. The most important type of cell for milk production is the milk-secreting cell. These cells are responsible for synthesizing milk proteins and secreting them into the milk.
The milk proteins are synthesized from amino acids that are transported into the cell from the blood. Once inside the cell the amino acids are assembled into milk proteins by a process called protein synthesis.
The milk-secreting cells are also responsible for the removal of water and minerals from the blood and the addition of these to the milk. This process is called milk composition.
After milk composition the milk is stored in the mammary gland until it is ejected from the nipple during milk let-down. Milk let-down is stimulated by the hormone oxytocin which is secreted by the pituitary gland.
The milk is then transported through the milk ducts to the nipple where it is available for the baby to drink.

How is milk produced in a cow’s mammary gland?
Milk is produced in a cow’s mammary gland when the cow’s pituitary gland produces a hormone called prolactin.

Prolactin causes the cells in the alveoli of the mammary gland to produce milk.
