Goodness, the article on the Berkshire site, relating to all rare breed pigs not just Berkshires, has completely thrown me. I wish I had known about it before - the feed amounts they recommend are massively lower than the classic formula of 1 lb per month-age up to 6 months. Very interesting indeed, and I think I will now adjust all my feeding programmes accordingly with a view to ending up with finished pigs that hopefully have back fat at 19 mm and under, something I have only so far achieved in two pigs ever.
