We have just had 6 of the 60/70kg to kill. Our butcher was really pleased as they were nice and lean.
Lighter ones killed out at 49/51kg DW, with the bigger ones being 55/56kg.
Haven’t had any real trouble with fatty pigs for a couple of years now after sorting out a suitable ration for these type of pigs.
Only have mid-stores left (up to 45kg) there are about 20 of them, with a dozen weaners coming on after.
