It's definately worth getting a good bit of experience before you start breeding. As you're learning - it's not always straightforward. Raise a few for pork before you dive straight into breeding. I don't mean to sound patronising or like a know-it-all, so please forgive me if it comes across that way, but you've got to be confident and competant in pig husbandry before you consider breeding,
if you want to do it properly. I'd suggest getting along to a pig keeping course (or local friendly pig keeper) to learn all the basics asap - including things like injecting, common ailments etc. Plus it's always good to build up a network of likeminded people in your area. Everyone's got to start somewhere, and there's no better plaace (in my humble opinion) than with pigs

But for your sake, and that of your pigs you've got to know what you're doing

Please don't be offended and please keep posting if you need advice (but there's no substitute for getting 'hands on'
