Abstract

The purpose of this study was to determine the genetic and phenotypic correlations between maternal and postweaning traits from a seedstock swine breeding system. The strongest phenotypic correlation was between percent lean and backfat at -0.72 (P<0.05). The genetic correlations between annualized farrowing interval and each of the postweaning traits (BF, PCL, and D100) were 0.41, -0.53, and 0.49 (P<0.05), respectively. The correlations between annualized farrowing interval and post-weaning traits suggest that selecting based on annualized farrowing interval would negatively impact the post-weaning traits in the herd. The direction of the correlation between number born alive and post-weaning traits could not be concluded from this study.
