Researches were conducted in 2009 on the Pedigree Farm Zadneprovsky in Vitebsk region (the Republic of Belarus) on Landrace breed of animals of Canadian selection and its crosses with Belarusian meaty breed. It was determined that animals of Landrace breed surpassed 2-breed coevals BMxL on meat performance traits. So backfat thickness above the 6-7th dorsal vertebra made 16,5 mm, the rear third part of half-carcass weight - 10,6 kg, loin area - 48,6 cm2. Purebred animals gave way on the carcass length, to crosses at 2,2% (P less than 0,05). The meat of young animals of all the genotypes tested was of a good quality, PSE or DFD signs were not determined, pH in 24 hours after slaughter made 5,6 acidity units. Analysis of chemical content of the longest back muscle didn't show variability on moisture, fat, ash and protein content
