Investigation of the phenotypic variability of traits of growth and carcass quality was carried out on 865 fatteners (394 female animals and 461 male castrated heads) originating from 29 sires (9 breeds-crossbreds: Swedish Landrace, Large White, Canadian Landrace, Canadian Yorkshire, Duroc, Canadian Duroc, Hempshire, Hempshire x Duroc, Pietrain x Duroc) and 197 dams (pure breed, two and three breed crosses). Investigation included following traits: age at slaughtering, body mass at slaughtering, daily gain of body mass during life cycle, mass of warm carcass sides, daily gain of carcass sides, quantity and content of meat in carcass sides, total mass and ratio of leg+shoulder+loin. All investigated traits varied under the influence of sire breed (P is less than 0.01), however not under the influence of dam breed except total quantity of meat in carcass sides and total content of meat in carcass sides (P is less than 0.05). Statistically highly significant differences were determined in regard to average values of all traits between female animals and male castrated heads (P is less than 0.01). All traits of carcass quality dependen on the mass of warm carcass (P is less than 0.01).
