My understanding is that dairy cows and beef cows are different breeds, and that dairy cow meat is not normally sold as beef. Is that not the case?

Last I heard dairy cows are butchered for low grade meat. They won't be in your top sirloin but maybe in your ground beef.

The livestock industry does its best to use everything.

Dairy cows produce milk to feed their you g. This, dairy cows are continuously bred through their lives. The female calves go on to be dairy cows. The male calves go on to be veal or low grade meat or animal food.

Once the dairy cow has finished being a dairy cow they're sold off as low grade meat.
