Summary of Additional Carcass Measures

Estimated carcass yield Probe fat depth
Probe lean depth Dressing percent
Carcass index Carcass moisture loss
Carcass length Weight of leaf fat
Maximum shoulder fat depth Minimum backfat depth
Minimum loin fat depth Shoulder as a % of side
Percent lean in shoulder Belly as a % of side
Loin as a % of side Percent lean in loin
Ham as a % of side Percent lean in ham
Percent lean in 3 primals PSS genotype
Skin thickness at back Skin thickness at loin
Skin thickness at chop Skin thickness at shoulder
Belly ratio 1 = length of lean streak/width of belly
Belly ratio 2 = minimum lean thickness/belly thickness
Belly ratio 3 = maximum lean thickness/belly thickness
