N2 - ABSTRACT: Purebred Duroc and Yorkshire sows werecrossed with Göttingen minipig boars to obtain two separateF2 intercross resource populations (n=287 and 279respectively). Several obesity, metabolic and slaughtermeasurements were recorded from birth to slaughter (220 ±45 days). In addition, body composition was determined atabout two months of age (64 ± 11 days) via dual-energy xrayabsorptiometry (DXA) scanning. All pigs weregenotyped using Illumina Porcine 60k SNP Beadchip and acombined LDLA approach was used to perform genomewidelinkage and association analysis for body fat traits.Subsequently bioinformatic analysis was performed toidentify genes in close proximity of chromosomal positionswhere statistically significant QTLs were identified. Severalimportant genes previously linked to obesity (e.g. BBS4,CHRNA2, DLK1), along with other novel genes wereidentified, that together provide novel insights that mayfurther the current understanding of the molecularmechanisms underlying human obesity.
