Background: In previous studies, a major QTL affecting fatness and growth has been mapped to pig chromosome1q (SSC1q) using Large White - Meishan intercrosses. A higher fat depth and a larger growth rate have beenreported for the allele of MS origin. Additionally the LW allele showed partial dominance effects over the MS allelefor both traits. In order to refine the QTL mapping interval, advanced backcross generations were produced.Recombinant heterozygous sires were mated to LW sows in order to progeny test the sire segregation of the QTLand refine the QTL localisation. However due to the partial dominance of the LW allele, BC scheme using LW asthe receiving population was not optimal.Results: To overcome the difficulties related to the dominance of the... |

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... |

Une expérience de croisement entre des lignées Large White (LW) et Meishan (MS) a été réalisée. Les effets génétiques additifs directs, maternels, grand-maternels ainsi que les effets d’hétérosis directs, maternels et paternels ont été estimés pour les caractères de productivité de la portée: nombre de porcelets nés totaux (NT), nés vivants (NV), sevrés (NS), poids de la portée à la naissance (PPN) et à 21 jours (PP21) ajustés ou non pour la taille de la portée, taux de survie de la naissance au sevrage (TS). Les effets additifs directs et maternels et les effets d’hétérosis direct ont été également estimés pour différents caractères de la truie: poids avant la mise bas (PTN) et au sevrage (PTS), perte de poids (PPT) et consommation alimentaire... |
