Maybe I'm off-base, but...
If he owns the zoo, and therefore owns the animals, what's the problem? Is it illegal to eat a pig? A buffalo? A rabbit? I myself have eaten all of these, after purchasing them and therefore gaining ownership of them. How is this any different?
I admit I've never eaten parrot or Shetland pony, but I'm curious: are there laws restricting what animals you can and can't eat, provided they are your property?
I'm sure I'll be straightened out, but the line, "Schlechte has already been fined £1,500 after admitting eating the pigs," really struck me as odd. There's a fine for eating a pig? What the hell?
