Abstract
A data set comprising 16 years of performance data from 1980 to October 1996 was used to compare Estimated Breeding Values (EBV's) for litter size in gilts with their lifetime phenotypic reproductive performance. EBV's for litter size were obtained with the genetic evaluation program PIGBLUP in 10 evaluations, using the cut-off dates January 1989, June 1989 and so forth until June 1993. Gilts obtained an EBV in litter size based only on pedigree information and were grouped in 10 percentile classes according to their EBV in litter size. The comparison between the top and bottom 10 percentile showed a difference in EBV's for number born alive of 0.96 piglets per litter. In their later life these gilts realised a difference in phenotypic performance of 0.91 piglets per litter. PIGBLUP provides a reliable tool to predict genetic differences in litter size. Keywords: Pigs, litter size, PIGBLUP.
