We raise our own pigs for meat, two at a time. Of those, we sell 1.5 and keep half a pig for ourselves. The sale of the other three halves just about pays for our meat.
It costs us about $275 to raise a pig and have it processed. One pig yields about 160 pounds of meat, so it's more or less $1.75 per pound. I don't know what pork goes for in the store, but I do know ours tastes WAY better than what we used to get in the store.
We keep the two pigs on close to half an acre of pasture, with a shelter they can get in to get out of cold or inclement weather. Their area is fenced with field fence and a single strand of electrified wire about 10 inches off the ground to keep them from rooting under it. We've never had anything get anywhere close to an escape; the electrified wire works wonders. With that much space, the smell has never been an issue.
We always get Yorkshires, which are the standard pink pigs you see in pictures.
That sounds like the ticket. We bought ours when we first moved to our property. It was completely unfenced at the time. The previous owners had a dog pen that was hodge podge. After the initial escape I bought 6 hog fence panels and made a secure enclosure. We had one other escape from one of the kids leaving the gate open. Putting them on a much larger plot would solve the stink problem somewhat. 2 pigs in a 32 x 32 enclosure with snow and rain liquifying there refuse is a nasty mess. Unless yopu have a tractor with a scoop cleaning it up is not an option. Their poop is not like a horses poop. It is much closer to human poop. We fed them cracked corn and table scraps. 3 years after they were butchered I rototilled the area for a garden and the smell was still horrible. Maybe I just have a sensitive nose. I can handle cow manure and horse manure doesn't bother me at all but pig poop? I'll stick to chickens and horses.
I have 3 pigs in one 32x32 enclosure and 2 pigs in another that size. We actually shovel poop out on a regular basis using a rake and shovel. So, I can tell you it is possible. I have neighbors with dogs and their yards smell worse than my pig pens. Everyone that comes to visit comments on the fact that they thought the pigs would smell much worse than they actually do.
