varies but dairy cows make up about 20% of the beef market
I’d surmise that meat from dairy type cows, especially if old and being retired from the dairy “industry,” mostly end up in ground meat, i.e., hamburger of low grade, and processed meats such as bologna, stuffed into casings for slicing and making sandwiches.
