The cow's mammary gland is called an udder. Mammary glands produce milk to nourish the baby calf. Mammary glands develop in the heifer prior to birth, and further develop and grow when the heifer is pregnant. Cells in the alveoli of the udder differentiate from other types of cells to be able to secrete milk into the alveoli cavity. Since there are many alveoli (singular: alveolus), all the milk that has been secreted from the cells into the alveoli empty into ducts and subsequent larger ducts which further lead to the gland or milk cistern where all the milk is collected until it is time for milking or for the calf to drink from.

The precise detail of how the udder develops in the cow is very complex, involving which cells differentiate in what way, growth and differentiation of the alveoli, expanding of the udder as the heifer gets closer to parturition, and milk secretion and synthesis. The general details posted above are as good as lay-men terms as I could make them.

Is a cow with a large udder inherited?

Udder size is heritable, yes. This is quantified by milk production: as we've seen in dairy cows, the larger the udder the more milk a cow will (or should) produce.


Does the size of the cow udder depend on how much the cow produces?

Not exactly. A cow can have a large udder yet produce a little amount of milk if she is either under stress or is not being fed properly. However, it is definitely true that a cow with a larger udder will be more productive in terms of milking ability than a cow with a smaller udder.

What to do with a Brahman cow who is not lactating and has a baby calf?

There are a number of things that you can do. If the cow has developed an udder and is just not letting her milk down, try to administer about 2-3 cc of oxytocin into the rump area (by the udder but not into the udder). Wait a couple of minutes after giving the needle and see if she has let her milk down (either have the calf suckle or strip some milk out of the udder by hand). If she has not developed an udder, you will have to either try to get another cow to adopt the calf or feed the calf milk replacer. You might have to cull the cow if she did not develop an udder as she may not be able to produce milk in the future.


When is there milk in the udder?

When the cow has just had a calf or is suckling a calf.
