Abstract

The effect of using boars with different origins Large white (LW) x English landrace (EL) and Danube white (DW) from the Gerana farm on the productive traits of Danube White pigs for three generations has been studied. Objective of the study were the basic selection traits – growth rate and lean meat percentage measured at 90kg live weight with Piglog 105. Other traits of productive performance have been included in the analysis as regression effects. Estimation of productive traits of pigs with different blood grading was performed by means of multitrait animal model (Sire model).The hybrid combinations were characterized by neutral to favourable effects including those of new origins. The analysis of animal model results established better productivity for crosses’ progeny and with respect to sex – for the male animals.
