Abstract
The purpose of this study was to determine the relationship between individual sires breeding values (BV) for litters/sow/year (LSY) and progeny farrowing rate means. The correlation between the LSY BV and the sire progeny mean farrowing rate was 0.21 for those sires who had 10 or more daughters. The correlation between LSY BV and sire progeny mean for farrowing rate suggests that selecting for LSY could positively impact farrowing rate.
