Positional candidate cloning of a QTL in dairy cattle: identification of a missense mutation in the bovine DGAT1 gene with major effect on milk yield and composition.

TL;DR: The positional candidate cloning of this QTL is reported, involving the construction of a BAC contig spanning the corresponding marker interval, and the demonstration that a very strong candidate gene, acylCoA:diacylglycerol acyltransferase (DGAT1), maps to that contig.
Molecular dissection of a quantitative trait locus: a phenylalanine-to-tyrosine substitution in the transmembrane domain of the bovine growth hormone receptor is associated with a major effect on milk yield and composition.

TL;DR: In this article, the authors used a denser chromosome 20 marker map and exploited linkage disequilibrium using two distinct approaches to provide strong evidence that a chromosome segment including the gene coding for the growth hormone receptor accounts for at least part of the chromosome 20 QTL effect.

TL;DR: The observation of long range disequilibrium between syntenic loci using low-density marker maps indicates that LD mapping has the potential to be very effective in livestock populations.
Fine-mapping of quantitative trait loci by identity by descent in outbred populations: Application to milk production in dairy cattle
Juliette Riquet,Wouter Coppieters,Nadine Cambisano,Juan José Arranz,Paulette Berzi,Scott K. Davis,Bernard Grisart,Frédérick Farnir,Latifa Karim,Myriam Mni,Patricia Simon,Jeremy F. Taylor,P. Vanmanshoven,Danny Wagenaar,James E. Womack,Michel Georges +15 more
TL;DR: The seven chromosomes increasing milk fat percentage were indeed shown to carry a common chromosome segment with an estimated size of 5 cM predicted to contain the studied QTL, providing additional support in favor of the location of the QTL within the corresponding interval.

TL;DR: The identification of a locus on the centromeric end of bovine Chromosome (Chr) 14, with major effect on fat and protein percentage as well as milk yield, is reported.
