Genome-association analysis of Korean Holstein milk traits using genomic estimated breeding value
Korean Holstein Genome-wide Association Studies (GWAS) Milk Production Milk Fat Milk Protein
2017/3/9
Holsteins are known as the world’s highest-milk producing dairy cattle. The purpose of this study was to identify genetic regions strongly associated with milk traits (milk production, fat, and protei...
Single-step prediction of genomic breeding value in a small dairy cattle population with strong import of foreign genes
genomic breeding value single-step prediction
2015/6/23
The breeding value (EBV) of Holstein cattle milk performance from the first lactation was
evaluated using a regular Animal Model or by Single-Step Prediction of the genomic breeding value (GEBV).

Polymorphisms in CGIL4, breeding value for somatic cell count and resistance to mastitis
mastitis CGIL4 somatic cells Czech Simmental cattle German Holstein cattle
2015/6/9
The relationship between a potential marker for mastitis, CGIL4, and the breeding value for somatic cell count (SCC) was analysed in a panel of Czech Simmental and German Holstein sires. Genotyping wa...
Analysis of Czech cold-blooded horses: genetic parameters, breeding value and the influence of inbreeding depression on linear description of conformation and type characters
breeding value inbreeding depression linear description of conformation cold-blooded horses
2015/6/9
Genetic parameters, breeding values and inbreeding depression for 22 linear type description of conformation and type characters and 4 body measurements were evaluated in a group of 1744 horses of thr...
Breeding value evaluation in Polish fur animals: Statistical description of fur coat and reproduction traits – relationship and inbreeding
fur animals fur coat inbreeding
2015/6/5
Three data sets were available: records on conformation and coat traits for the arctic fox from one farm (5 540 observations, collected between 1983 and 1997), and the same traits for the silver fox f...
Relationships among body condition score, milk yield and sires’ breeding value for beef production efficiency in Czech Fleckvieh cattle
body condition score (BCS) relative breeding value (RBV) net daily gain (NG) milk yield Czech Fleckvieh
2015/6/5
The objective of this study was to analyze the relationships among cows’ body condition score before calving, subsequent BCS changes, milk yield, lactation characteristics and their sires’ relative br...
Stochastic simulation of the influence of insemination on the estimation of breeding value and its reliability
beef cattle breeding value connectedness reference sires reliability stochastic simulation
2015/6/4
Insemination is used less commonly in the population of beef cattle than in dairy cattle. As a consequence, herds are genetically isolated and their comparison is difficult. The objective of the paper...
Breeding value evaluation in Polish fur animals: Estimates of (co)variances due to direct and litter effects for fur coat and reproduction traits
arctic fox fur coat traits genetic parameters normal probability scale transformation reproductive traits
2015/6/2
5 540 records of the arctic fox fur coat and reproductive traits collected in 1983–1999 were studied. The analyzed traits were: body size (BS), colour type (CT), colour purity (CP), coat density (CD),...
Breeding value evaluation in Polish fur animals: Estimates of direct heritability and portion of litter variation of fur coat and reproduction traits
arctic fox fur coat heritability
2015/6/1
The study presents estimates of heritability for fur coat and reproduction traits in arctic and silver foxes kept on Polish farms. The estimates of variance components were calculated using the DFREML...
Genome Wide Association Studies Using Multiple-lactation Breeding Value in Holsteins
Single Nucleotide Polymorphism Milk Production Traits Lactation, Holstein
2016/5/18
A genome wide association study was conducted using estimated breeding value (EBV) for milk production traits from 1st to 4th lactation. Significant single nucleotide polymorphism (SNP) markers were s...
