Who is the poor-mans-cow?

Answer 1

It's not a matter of "who," but more a matter of "what." What would be the so-called "poor-man's cow" would probably be a breed of bovine that is considered to be dual- or trio-purpose: a breed that is capable of producing meat, milk and can also be used for draft purposes. Red Polls, Ancient White Park cattle and Devon cattle are such breeds that fit the bill.
