Genome-wide association mapping for female fertility traits in Danish and Swedish Holstein cattle.
A genome-wide association study was conducted using a mixed model analysis for QTL for fertility traits in Danish and Swedish Holstein cattle. The analysis incorporated 2,531 progeny tested bulls, and a total of 36,387 SNP markers on 29 bovine autosomes were used. Eleven fertility traits were analyzed for SNP association. Furthermore, mixed model analysis was used for association analyses where...
متن کاملGenome-wide Association Study to Identify Genes and Biological Pathways Associated with Type Traits in Cattle using Pathway Analysis
Extended Abstract Introduction and Objective: Type traits describing the skeletal characteristics of an animal are moderately to strongly genetically correlate with other economically important traits in cattle including fertility, longevity and carcass traits. The present study aimed to conduct a genome wide association studies (GWAS) based on gene-set enrichment analysis for identifying the ...
متن کاملGenome Wide Analysis of Fertility and Production Traits in Italian Holstein Cattle
A genome wide scan was performed on a total of 2093 Italian Holstein proven bulls genotyped with 50K single nucleotide polymorphisms (SNPs), with the objective of identifying loci associated with fertility related traits and to test their effects on milk production traits. The analysis was carried out using estimated breeding values for the aggregate fertility index and for each trait contribut...
متن کاملGenome scan detects quantitative trait loci affecting female fertility traits in Danish and Swedish Holstein cattle.
Data from the joint Nordic breeding value prediction for Danish and Swedish Holstein grandsire families were used to locate quantitative trait loci (QTL) for female fertility traits in Danish and Swedish Holstein cattle. Up to 36 Holstein grandsires with over 2,000 sons were genotyped for 416 microsatellite markers. Single trait breeding values were used for 12 traits relating to female fertili...
متن کاملA Genome-wide Association Study of Non-additive Effects for Milk Yield and Fertility in Holstein and Jersey Dairy Cattle
It has been suggested that traits associated with fitness, such as fertility, may have proportionately more genetic variation arising from non-additive effects than traits with higher heritability, such as milk yield. Here, we performed a large genome scan with 408,255 single nucleotide polymorphism (SNP) markers to identify chromosomal regions associated with dominance and epistatic (pairwise ...
