Pigs take up very little space, and if raised in a proper pen, can grow extremely fast. You can pull a 325lb pig in 200 days, and have a freezer full of meat all year long. Pigs are social animals, so you’ll need at least two.
That’s a lot of meat. If you play your cards right, you can trade for beef or venison, and have a well-rounded meat freezer for your family. Alternatively, keep one/sell one.
Soon enough, you’ll find yourself profiting, and eating fresh homegrown meat that pays for itself.
