The Fattening and Slaughter Value of Polish Large White and Polish Landrace Gilts Slaughtered at a Body Weight of 100 kg

摘要

The assessment covered 28 gilts of the Polish Landrace breed (PL) and 24 gilts of the Polish Large White breed (PLW). The gilts came from pig breeding stocks located in the territory of Pomorze and Kujawy. Controlled fattening was carried out within strict limits of 30-100 kg body weight, in standardized conditions applicable at the Polish Pig Testing Stations. Each animal was treated individually, including the application of single pig pens. Control weighing of the animals was carried out every 2 weeks during fattening and upon reaching the body weight of 100 kg the animals were slaughtered and subject to post-slaughter assessment in accordance with the relevant procedures applicable in the Polish Pig Testing Stations (Ró?ycki, 1996).
