I weighed the pigs at 5 months old. GxGxL/400. And then /2.2 =53kg. Quite pleased with this, they are lean and spend a lot of time rooting and browsing. I think 2 or 3 months more will see them at killing weight.
I then measured myself with the same formula. Came up with 9.5 stone when in fact I'm 12.5 stone. This means I cannot be a pig.
