Abstract

Growing pigs were fed either ad libitum to 85 kg live weight, or ad libitum to 95 kg and then half maintenance until their live weight was reduced to 85 kg, when both groups were slaughtered. The middles were divided into eye, wedge and belly dorso-ventral portions and dissected. The carcasses of pigs which lost live weight before slaughter had less fat in the wedge, and less fat and muscle in the belly. They also had a greater proportion of the total middle fat and muscle in the eye portion, less fat in the wedge and less muscle in the belly portion.
