Abstract
The aim of the study was to determine the influence of breed and sex on daily gain in field test of pigs. The research included 62,469 data records of pigs in test from 1998 to 2017. Four pure breeds were included in the study: Landrace (L), Large White (LW), Pietrain (P), Duroc (D) and crossbreeds between LxLW and LWxL. Both studied effects had significant effect (P<0.05) on daily gain. The difference in daily gain between breeds was found to be statistically significant. Duroc pigs had the highest least square means for daily gain rate of 583 g, while least squared means for daily gains were 532 g and 529 g for LxLW and LWxL, respectively. The lowest average daily gain of 519 g was found in Pietrain. The difference in daily gain in field test between the sexes (young boar and gilts) was statistically significant (P<0.05). The observed least squared means for daily gain were 569 g and
508 g for young boars and gilts, respectively.
