Quantitative trait loci analysis for growth and carcass traits in a Meishan x Duroc F2 resource population.
Analysis of marker genotypes supported the breed of origin results and provided further evidence that a suggestive QTL for circumference of cannon bone also was segregating within the Meishan parent.
Identification of quantitative trait loci affecting corpora lutea and number of teats in a Meishan x Duroc F2 resource population.
This study utilized a 3-generation resource population, in which the founder grandparental animals were purebred Meishan and Duroc pigs, in a genome scan for QTL, and identified 9 QTL for 3 traits at a 10% genome-wise significance level.
Quantitative trait loci analysis for growth and carcass traits in a Meishan × Duroc F 2 resource population
A pig F2 resource population constructed by crossing a Meishan sow and a Duroc boar to locate economically important trait loci showed evidence for significant quantitative trait locu affecting weight at 30 d and average daily gain on Sus scrofa chromosome (SSC) 6.
Bovine quantitative trait loci analysis for growth, carcass, and meat quality traits in an F2 population from a cross between Japanese Black and Limousin.
A genome-wide scan for QTL affecting economically important traits in beef production was performed using an F(2) resource family from a Japanese Black x Limousin cross, where 186 F(2) animals were…

RPL consumed prepartum tended to increase postpartum DMI and increased energy-corrected milk and milk component yields, which indicates that prepartsum supply of intestinally available Lys is pertinent to post partum performance.
High-resolution physical mapping and construction of a porcine contig spanning the intramuscular fat content QTL.
This study identified 34 microsatellite markers and 14 STSs from the 17.1-cM IMF quantitative trait loci (QTL) region corresponding to HSA14q and aligned those loci using the INRA-University of Minnesota porcine radiation hybrid (IMpRH) panel.
Identification of quantitative trait loci affecting corpora lutea and number of teats in a Meishan × Duroc F 2 resource population
Understanding of the genetic control of female reproductive performance in pigs would offer the opportunity to utilize natural variation and improve selective breeding programs through…
A quantitative trait locus for body conformation maps to bovine chromosome one in Japanese Black cattle
The detection of these QTL boosts the prospect of implementing marker-assisted selection for body conformation traits in Japanese Black beef cattle.
Microsatellite DNA marker mapping of bovine chromosome one for QTL affecting birth weight and preweaning growth in Japanese Black Cattle (Wagyu)
It was concluded that evidence of significant QTL in chromosomal regions of bovine chromosome one was compelling for birth weight hence enhancing the prospects of marker-assisted selection in this breed.
Genome scan of BTA1 for QTL affecting weaning weight, yearling weight and post-weaning growth in Japanese Black cattle
Since PWADG is positively correlated with WT6 and WT12 in beef cattle, the identification of these QTL in Japanese Black Cattle holds a high prospect for the implementation of marker-assisted selection for the early attainment of slaughter weight in this breed.
