Lactorrhea, the occasional production of milk by the glands, can occur in any mammal, but in most mammals lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years. It is directed by hormonal guidance from sex steroids.
The mammary gland of the dairy cow consists of four separate glands each with a teat. Milk which is synthesized in one gland cannot pass over to any of the other glands.

When the cow is producing 60 liters of milk per day, 30,000 liters of blood are circulating through the mammary gland.
