Market weights for a facility will depend on the genetics, the feeding program, and the packer’s requirements. The packer will generally have a range of acceptable weight, but pay more for a smaller core range. Backfat and lean mass can also impact the price the packer will pay for a hog. The price the packer pays is determined by a settlement sheet, which takes into account weight and carcass characteristics. Weighing pigs is time-consuming, but can result in more profit from the packer. Auto-sorters can reduce time and labour needed to sort out ideal market size pigs. However, pigs need to be accustomed to it and stress should be reduced for the pigs by providing space, feed, water, and reducing time spent waiting.
