Interval mapping of growth in divergent swine cross

Abstract: A genomic scan of 18 swine autosomal chromosomes was constructed with 119 polymorphic microsatellite (ms) markers to identify quantitative trait loci (QTL) for 11 growth traits in the University of Illinois Meishan x Yorkshire Swine Resource Family. A significant QTL effect was found for post-weaning average daily gain (ADG) between 5.5 and 56 kg of body weight that mapped between markers SW373 and SW1301 near the telomere of Chromosome (Chr) 1 q (SSC1). This QTL effect had a nominal (pointwise) p-value of 0.0… Show more

“…Similarly, growth gene results were consistent with those obtained in Chinese × White crossbred populations on SSC 1 by Paszek et al [28] for early growth, on SSC 4 by Walling et al [36] and Wang et al [38], in the SLA region on SSC 7 with a fast-growth Meishan allele, by Rothschild et al [35] and Wang et al [38], and in the centre of SSC 13 by Yu et al [40]. Walling et al [36] also detected a QTL on SSC 7, but at a different position and with a favourable Large White allele.…”

“…edu/cgi-bin/QTLdb/BT/index), we only found milk traits in this region, however, some QTLs about growth and meat quality traits were found on the animals that were usually used to study the growth and meat quality traits, such as the swine and chicken RXR gene. The swine RXR gene located on chromosome 1 about from 288.83 to 288.86 Mb, in this region some QTLs associated with production and meat quality traits was mapped, such as abdominal fat weight [29], backfat [30,31], body weight [32] and average daily gain [32,33]. The chicken RXR gene was located on chromosome 17 about from 7.27 to 7.35 Mb, and we found some QTLs associated with meat quality traits located in this region, such as abdominal fat percentage and drumstick weight [34], bone mineral content and tibia length [35], abdominal fat weight [36], body weight [37].…”

“…The present study shows that Large White alleles have favourable effects on both lean and fat cut weights, with slightly larger effects on lean cuts than on fat cut weight. This genomic area has also been identified as affecting backfat thickness [6,13,39,40], postweaning growth rate [6,34,39], as well as vertebra number in a Meishan × Göttingen cross [44]. Two candidate genes, i.e.…”
