| Resumo: |
A genome-wide scan was performed in Large White and French Landrace pig populationsin order to identify QTL affecting reproduction and production traits. The experimentwas based on a granddaughter design, including five Large White and three French Landracehalf-sib families identified in the French porcine national database. A total of 239 animals(166 sons and 73 daughters of the eight male founders) distributed in eight families were genotypedfor 144 microsatellite markers. The design included 51 262 animals recorded for productiontraits, and 53 205 litter size records were considered. Three production and three reproductiontraits were analysed: average backfat thickness (US_M) and live weight (LWGT) at the endof the on-farm test, age of candidates adjusted at 100 kg live weight, total number of pigletsborn per litter, and numbers of stillborn (STILLp) and born alive (LIVp) piglets per litter. TenQTL with medium to large effects were detected at a chromosome-wide significance level of5% affecting traits US_M (on SSC2, SSC3 and SSC17), LWGT (on SSC4), STILLp (on SSC6,SSC11 and SSC14) and LIVp (on SSC7, SSC16 and SSC18). The number of heterozygousmale founders varied from 1 to 3 depending on the QTL
