Hi WP, A friend of mine has pietrain x duroc (pedigree) and sent to slaughter at 6 month and was 79 kilos dead weight. You can push the pigs further but you need to have a slaughterhouse that will take large pigs. What ever slaughterhouse you are using please find out what the maximum weight is that they can take or you may have your pigs too big and refused unloading. The weight you state 110 & 100 is that live weight or dead weight?
