The main objective of this study was to investigate the importance of the sires effect on phenotypic variability of production traits of performance tested boars of Large White, Landrace, and Hampshire breeds of pig. The data used in this study were collected from 738 performance tested boars at the PKB Pig Testing Station in Padinska Skela (Serbia) from 1995 to 2001. Analyzed traits were initial age, final age, test duration, average daily gain on test, lifetime, amount of total consumed feed, feed conversion ratio, daily feed intake, and body composition traits taken by ultrasonic equipment PIGLOG 105 (backfat thickness, muscle depth, and lean meat content). Data was analysed by fixed models of least squares method. Analysis of variance showed that sires nested within Hampshire breed highly significant influenced all investigated traits. Growth, feed efficiency and body composition traits, except muscle depth, were highly significant influenced by sires of Large White breed. All feed efficiency traits and muscle depth were not influenced by sires within Swedish Landrace breed.
