What are cow udders used for?

A cow’s udder is the part of its body that produces milk. When you milk a cow, you empty its udder by squeezing the milk into a bucket. Moo! To milk any four-legged ruminant, you need to carefully squeeze and pull each teat after cleaning the udder.

Why are cow called udders?

Not only do they need a whole lot of milk, but because they need space in their abdomen for a rumen, they don’t really have space for a great big milk cistern in there. This is why they have developed an udder: there isn’t space for all the necessary milk internally.
