A modern day equivalent that comes to mind are the facilities in China that breed tigers primarily for use in Traditional Chinese Medicine but have a display portion/zoo as a front for the breeding for slaughter. While it doesn't seem like there's evidence that the Mayan Jaguar breeding had a display facility as a front (though I don't know), it's interesting to consider whether or not you would call a place a zoo if the main purpose was to breed exotic animals for slaughter but with some sort of portion where the animals were on display as well, at least before their eventual slaughter.
I don't know, though I'm inclined to think that most zoochatters would call a place like that a zoo, even if the animals were eventually destined for slaughter. And even if the Mayan Jaguar breeding "zoo" didn't have animals on display, would it then be a "private collection"?
