Abstract

Data from centrally tested boars over a 6-year period were analysed. Animals were performance tested from 35-86 kg on a restricted feeding system. The traits analysed were daily gain (DG) g, food conversion ratio (FCR) and ultrasonic k backfat (BF) mm. Estimates of heritabilities, phenotypic and genetic correlations were obtained from a paternal half-sib analysis. The estimated heritabilities for DG, FCR and BF were 0.34, 0.20 and 0.37, respectively. The estimated correlations between the traits are in agreement with correlations reported in literature for traits measured in pigs on restricted feeding.
