Can confirm. A neighbour had a cow that would batter down fences to get out and chase people, and headbutt cars. Didn't matter how we fenced the field off, she'd break out.

Turns out a deep freeze is plenty stockproof. No-one's got time for that nonsense, and every last bit was delicious right down to the last drop of oxtail soup.
