The Mammary Gland Anatomy – Examining the Milk Production System of Dairy Cows lesson is designed to introduce participants to the general anatomy of the lactating mammary gland and flow of milk letdown using the bovine (cattle) mammary gland as a model. It is a two-step process that involves the death of the secretory epithelium and its replacement by adipo-cytes.

It appears that the mammary gland, like the liver, can deaminate amino‐acids with the production of urea–at least in some animals, and it is likely that in forms in which the mammary gland arginase levels are elevated during lactation, the process is an important element in the metabolism of the lactating gland. In all species, the glands are composed of various cell types, and it is the epithelium, embedded in the fatty stroma (commonly known as the “fat pad”), that is targeted for proliferation and differentiation. 1 The mammary glands are modified sweat glands. Mammary gland – modified sudoriferous gland that produces milk.
