Just to clarify what somebody said-- "Heritage Breeds" are actually not the common ones like Yorkshire, Duroc and Hampshire. Heritage breeds are the more rare ones that are rarely if ever raised commercially anymore, such as Tamworth, Large Black, and Mulefoot. Either are fine to raise, or more likely you'll find cross bred pigs for sale. For your first time I wouldn't buy anything over 50 lbs, preferably more like 30 or so.
We just bought two little crossbred pigs, a guilt and a barrow, and they are around 15-20 lbs. I fenced in my garden and put them in there, but they kept getting out so I built an 8x8 pen for them out of 2' high OSB (I ripped two sheets down the middle for four pieces 2'x8', and nailed them at the corners with 2x4 pieces). The little twerps haven't gotten out since then. I have a little plastic dog house I use for their shelter, and give them hay to burrow in. When they get bigger I'll let them out in the garden and let them till it all winter.
