It is not that hard. Be sure to buy a home size meat grinder. I bought one years ago and it sure has come in handy. Right now a neighbor lady is using it to make her first ever sausage from a wild hog her husband trapped.I have never butchered my own meat.
There's old-fashion home economics and there's retail cuts. If you want to use the whole hog, I think you've got to do it yourself.We unfortunately learned the hard way that not everyone who claims they know how to butcher an animal can actually do it properly. And turning your back can end up costing you dearly too. We've lost a good few pounds of meat that somehow made it to the off-cuts piles. Like the pigs' necks that suddenly got very short! I'd say if you have to send an animal off to butcher, make sure you can trust the people, make sure they are experienced and will do the job properly, especially the killing part.
