Abstract
A study was made of certain differences observed in 385 littermate barrow and gilt pairs tested in the Ohio Swine Evaluation Station. The barrows gained faster than the gilts. The gilts produced leaner carcasses than the barrows, based on percent of lean cuts of carcass weight, backfat thickness and loin eye measurement, and weight of loin and ham. Loin eye area was correlated positively and backfat measurements negatively with primal cut yield of live weight in both barrows and gilts. Pounds of ham and pounds of loin in both barrows and gilts were positively correlated with loin eye measurements. Backfat and loin eye measurement were more closely correlated than carcass length with lean cuts of carcass weight and/or primal cuts of live weight.
