This study investigates the effect of sex (barrows and gilts) and slaughter weight on growth performance and carcass characteristics using crossbred pigs from Duroc sires mated to Landrace x Large White dams. These pigs were intended for high quality dry-cured hams (Teruel ham) from Spain. It was concluded that barrows were better than gilts when intended for Teruel ham. Also, an increase in slaughter weight up to 130 kg in pigs impaired growth performance but improved some aspects of carcass quality that is required by the Teruel ham industry.
