This isn't feed you will be able to get at a local feed store. It is only a very special feed that the large farrowing barns use when they early wean pigs at 2-3 weeks. At that age they need such high levels of nutrition because they
should still be nursing that they have to feed them animal product feeds and the pig blood is a very big ingredient in them. When I was raising piglets I always left them on the sows for at least 6 weeks and preferably 8 weeks. The super early weaning is done to produce three litters a year for the magical 30 pigs goal. I always felt two good litters a year was
enough and it didn't wear out the sows like the production factories do where they replace them every two years.
