In the conditions of the Republic of Belarus there was carried out the analysis of characteristic of productivity and meat qualities delivered and received in the conditions of breeding farms of the republic of replacement young growth of breed Landras of the Canadian selection. It was revealed that the replacement young growth of Landras breed of Canadian selection possesses intensive growth capacity. The age of achievement of alive weight of 100 kg at animal enterprise 'Zadneprovsky' from 2008 to 2011 decreased by 19,2% and made 152,3 days. As a result of research it has been established that the replacement of Canadian selection is noted for high level of assessment characters on their own performance and of meat characters. Meat content in the carcass of replacement stock at the breeding hybrid centre 'Zadneprovsky' in 2011 was 60.5 %, at the peasant farm enterprise 'B.S. Todrika' – 65.1 %. It has been revealed that values of correlation coefficients between performance characters of replacement young growth were at medium and high levels and fluctuated anywhere from 0.2 to 0.9.
