We analysed the meatiness of pigs slaughtered in commercial conditions of meat proccessing factories in Slovakia during the years 1995-1997. The lean meat content (LMC) of carcass body measured by FOM apparatus on 470 634 animals were taken into account. The average LMC in the subset of 136 179 animals slaughtered in 1995 with average dead weight 90.77 kg achieved 47.59% (tab. I) while the LMC increased to 48.74% for subset of 143 857 animals measured in 1997 at average dead weight 90.87 kg (tab. 3). Number of pigs classified as S, E and U rose from 29.71% in 1995 to 41.21% in 1997. More than 30% animals within each of the studied years were slaughtered at the weight from 90.1 to 100 kg. The pigs with dead weight over 110 kg created 8.14 - 10.32% of all analysed data (tab 4). We analysed the average dead weight and average LMC of pigs across years and months as well as the effect of increasing dead weight on the LMC. The content of lean meat in carcass has been decreasing linearly from the dead weight higher than 75 - 80 kg
