Genome-wide association of milk fatty acids in Dutch dairy cattle

Description :

Abstract

Background

Identifying genomic regions, and preferably individual genes, responsible for genetic variation in milk fat composition of bovine milk will enhance the understanding of biological pathways involved in fatty acid synthesis and may point to opportunities for changi...

Confirmation of quantitative trait loci affecting fatness in chickens

Description :

Abstract

In this report we describe the analysis of an advanced intercross line (AIL) to confirm the quantitative trait locus (QTL) regions found for fatness traits in a previous study. QTL analysis was performed on chromosomes 1, 3, 4, 15, 18, and 27. The AIL was created by random intercr...

Sensitivity of methods for estimating breeding values using genetic markers to the number of QTL and distribution of QTL variance

Description :

Abstract

The objective of this simulation study was to compare the effect of the number of QTL and distribution of QTL variance on the accuracy of breeding values estimated with genomewide markers (MEBV). Three distinct methods were used to calculate MEBV: a Bayesian Method (BM), Least Ang...

Genomic regions associated with bovine milk fatty acids in both summer and winter milk samples

Description :

Abstract

Background

In this study we perform a genome-wide association study (GWAS) for bovine milk fatty acids from summer milk samples. This study replicates a previous study where we performed a GWAS for bovine milk fatty acids based on winter milk samples from the same populatio...

A genome-wide association study on androstenone levels in pigs reveals a cluster of candidate genes on chromosome 6

Description :

Abstract

Background

In many countries, male piglets are castrated shortly after birth because a proportion of un-castrated male pigs produce meat with an unpleasant flavour and odour. Main compounds of boar taint are androstenone and skatole. The aim of this high-density genome-wide...

Mapping carcass and meat quality QTL on Sus Scrofa chromosome 2 in commercial finishing pigs

Description :

Abstract

Quantitative trait loci (QTL) affecting carcass and meat quality located on SSC2 were identified using variance component methods. A large number of traits involved in meat and carcass quality was detected in a commercial crossbred population: 1855 pigs sired by 17 boars from a sy...
