What is one skeleton function of cow?

It's not accurate to say a cow has a "skeleton function." A skeleton is the structure that supports the body of an animal, and all animals have skeletons, including cows.

Here's how you could rephrase your question to get a better answer:

* What is one function of a cow's skeleton?

* The answer to this could be things like: providing support for the body, protecting vital organs, enabling movement, etc.

* What is a unique skeletal feature of cows?

* This could refer to things like the specific shape of their vertebrae, the presence of a dewclaw, or their complex digestive system.
