He has a layman’s way of expressing himself, but he is probably right.
Cows have been bred to be as domesticated and docile as possible to a point where they probably could not survive in the wild.
Reminds me of my father’s response to a young woman from PETA: “After 10,000 years of domestication, the natural environment for a cow is a barn.”
They quite capable in the wild. They will defend defend themselves against an attack.
A donkey among the herd is even better. They kick a wolf or coyote until dead.
