And given the number of people shown both inside the compound and outside it, there looked to be plenty of mouths to feed. And experienced butcher(s) (or many rural farmers, for that matter) can process a fair number of corpses fairly quick. Add in basic meat preservation techniques, and even the quibble requiring a ravenous appetite goes away.
In fact, it makes more sense to slaughter and process as quickly as you can - when getting maximum caloric input is a necessity, feeding an animal to make food is an incredibly wasteful choice. Wasting food on them just to keep them "fresh" until you're ready to eat them is a luxury that cannot be afforded - instead you kill them fairly quick (with some cautionary quarantine time) and process/eat what you can in the moment.
Now there is one part of the scene, IMO, that does fail the inspection assumption. In my experience when a rib cage of an animal is processed for meat, the ribs are not left as an intact group and all still attached to vertebrae. What would be discarded in a refuse pile would thus just be loose bones. But then chalk that up to showbiz decision making, not realism - such a scene wouldn't have had the same unambiguous impact.
An experienced butcher in this day in age is still largely dependent upon electricity, and there's seemingly not much of that going around. The refrigeration alone... Or a simpler explanation is that they could be feeding the zombies that are conspicuously absent from the perimeter. They probably have them all in a subbasement.
The thing to me that makes this whole enterprise unrealistic is that you could convince more than a handful of people that eating people is okay in an environment where food can be grown, game can be hunted, and there are still houses left to be scavenged from. I don't buy it.
