Lovely information and very true, Yorkshires get pretty big though, my grandpa had a 500 pound show female who won a lot of shows but he ate her... very sad he was.
I don't know about your state but feeder pigs for me typically cost $65-100.
not sure about how much the cost is per year since were just starting on getting pigs in the spring but the bags of feed can cost up to $50 dollars.
I'm using my pigs for meat and breeding so i'm just making a simple...
