Abstract

Purebred Duroc and Yorkshire sows were crossed with Göttingen minipig boars to obtain two separate F2 intercross resource populations (n=287 and 279 respectively). Several obesity, metabolic and slaughter measurements were recorded from birth to slaughter (220±45 days). In addition, body composition was determined at about two months of age (64±11 days) via dual-energy x-ray absorptiometry (DXA) scanning. All pigs were genotyped using Illumina Porcine 60k SNP Beadchip and a combined LDLA approach was used to perform genome-wide linkage and association analysis for body fat traits. Subsequently bioinformatic analysis was performed to identify genes in close proximity of chromosomal positions where statistically significant QTLs were identified. Several important genes previously linked to obesity (e.g. BBS4, CHRNA2, DLK1), along with other novel genes were identified, that together provide novel insights that may further the current understanding of the molecular mechanisms underlying human obesity.

Conference

Conference	10th World Congress of Genetics Applied to Livestock Production
Country/Territory	Canada
City	Vancouver
Period	17/08/14 → 22/08/14
Other	The joint US-Canada organizing committee is proud to welcome you to the 10th World Congress on Genetics Applied to Livestock Production (WCGALP) being held from 17 – 22 August 2014 at the Westin Bayshore Conference Center situated on the bay in the gorgeous city of Vancouver, British Columbia, Canada. This congress is the premier conference for researchers and professionals involved in genetic improvement of livestock. Delegates from around the world gather every four years to attend the scientific program and network with colleagues. This 10th WGCALP builds from previous successful congresses in Madrid (1974 and 1982), Lincoln (USA, 1986), Edinburgh (UK, 1990), Guelph (Canada, 1994), Armidale (Australia, 1998), Montpellier (France, 2002), Belo Horizonte (Brazil, 2006) and Leipzig (Germany, 2010).
