Carcass grading was introduced in Slovenia in 1996 in larger slaughter hauses. The method is based on loin fat thickness, loin muscle depth, and warm carcass weight. Altogether 1095405 pigs were evaluated and slaughter protocols were sent to a central database. The data were used to evaluate lean meat contents for pigs slaughtered in Slovenia between June 1996 and December 1999. The results during observed periode showed that lean meat content at given carcass weight increased over time, as well as number of pigs slaughtered per month. The sample of 1417 fatteners with known gender and genotype showed that gilts are 2.40% more lean. At the same age, barrows had for 23.48g higher daily gain of warm carcass weight.
