A locally congenic backcross design in pig: a new regional fine QTL mapping approach miming congenic strains used in mouse Inra
Riquet, J.; Gilbert, H.; Servin, B.; Sanchez, M.P.; Iannuccelli, N.; Billon, Y.; Bidanel, J.P.; Milan, D..
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...

Combining two Meishan F2 crosses improves the detection of QTL on pig chromosomes 2, 4 and 6 Inra
Tortereau, F.; Gilbert, H.; Heuven; Bidanel, J.P.; Groenen; Riquet, J..
Background: In pig, a number of experiments have been set up to identify QTL and a multitude of chromosomalregions harbouring genes influencing traits of interest have been identified. However, the mapping resolutionremains limited in most cases and the detected QTL are rather inaccurately located. Mapping accuracy can beimproved by increasing the number of phenotyped and genotyped individuals and/or the number of informativemarkers. An alternative approach to overcome the limited power of individual studies is to combine data from twoor more independent designs.Methods: In the present study we report a combined analysis of two independent design (a French and a DutchF2 experimental designs), with 2000 F2 individuals. The purpose was to further map QTL for...

Detection of quantitative trait loci for reproduction and production traits in Large White and French Landrace pig populations Inra
Tribout, T.; Iannuccelli, N.; Druet, T.; Gilbert, H.; Riquet, J.; Gueblez; Mercat; Bidanel, J.P.; Milan, D.; Le Roy, P..
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...

Identification of QTL with effects on intramuscular fat content and fatty acid composition in a Duroc × Large White cross Inra
Sanchez, M.P.; Iannuccelli, N.; Basso, B.; Bidanel, J.P.; Billon, Y.; Gandemer, G.; Gilbert, H.; Larzul, C.; Legault, C.; Riquet, J.; Milan, D.; Le Roy, P..
Background: Improving pork quality can be done by increasing intramuscular fat (IMF) content. This trait is influenced by quantitative trait loci (QTL) sought out in different pig populations. Considering the high IMF content observed in the Duroc pig, it was appealing to determine whether favourable alleles at a major gene or QTL could be found. The detection was performed in an experimental F2 Duroc × Large White population first by segregation analysis, then by QTL mapping using additional molecular information. Results: Segregation analysis provided evidence for a major gene, with a recessive Duroc allele increasing IMF by 1.8% in Duroc homozygous pigs. However, results depended on whether data were normalised or not. After Box-Cox...

Number and mode of inheritance of QTL influencing backfat thickness on SSC2p in Sino-European pig pedigrees Inra
Tortereau, F.; Gilbert, H.; Heuven, H.C.M.; Bidanel, J.P.; Groenen, M.A.M.; Riquet, J..
Background: In the pig, multiple QTL associated with growth and fatness traits have been mapped tochromosome 2 (SSC2) and among these, at least one shows paternal expression due to the IGF2-intron3-G3072Asubstitution. Previously published results on the position and imprinting status of this QTL disagree betweenanalyses from French and Dutch F2 crossbred pig populations obtained with the same breeds (Meishan crossedwith Large White or Landrace).Methods: To study the role of paternal and maternal alleles at the IGF2 locus and to test the hypothesis of asecond QTL affecting backfat thickness on the short arm of SSC2 (SSC2p), a QTL mapping analysis was carried outon a combined pedigree including both the French and Dutch F2 populations, on the progeny of F1...

Six générations de sélection divergente pour la consommation journalière résiduelle chez le porc en croissance : réponses corrélatives sur les caractères de reproduction des truies et synthèse des réponses sur les caractéristiques de production Inra
Sellier, P.; Billon, Y.; Riquet, J.; Lagant, H.; Calderon, J.A.; Guillouet, P.; Bidanel, J.P.; Noblet, J.; Gilbert, H..
La consommation moyenne journalière résiduelle (CMJR) est définie comme la différence entre consommation observée et consommation prédite d’après les besoins d’entretien et de production. Une expérience de sélection divergente sur la CMJR de porcs Large White en croissance (faible CMJR : CMJR−; forte CMJR : CMJR+) a permis d’estimer les paramètres génétiques et les réponses corrélatives à la sélection pour certains caractères de reproduction des truies. Les données de 1071 portées (480 truies) ont été analysées. L’héritabilité (h2) de la perte de gras dorsal des truies pendant la lactation a été estimée à 0,13±0,02. Ce caractère a présenté une corrélation génétique négative avec la CMJR (rA = −0,41±0,12). La consommation moyenne journalière (CMJ) des...
