Journal ArticleDOI
Genotype by environment interaction for milk production traits between organic and conventional dairy cattle production in The Netherlands.
TL;DR: The findings indicate that moderate GxE was present for yield traits and heritabilities of milk, fat and protein yield, and somatic cell score (SCS) were higher under organic farming conditions than under conventional farming conditions.
Journal ArticleDOI
Genomic prediction using preselected DNA variants from a GWAS with whole-genome sequence data in Holstein–Friesian cattle
TL;DR: There was no advantage in using dense sequence information for genomic prediction in the Holstein data used in this study and the proportion of variance explained and the accuracy of genomic prediction by using imputed sequence data or preselected SNPs from a genome-wide association study with imputed whole-genome sequence data.
Journal ArticleDOI
Effects of genomic selection on genetic improvement, inbreeding, and merit of young versus proven bulls
TL;DR: This stochastic simulation study shows that genomic selection in combination with a severe reduction in the generation interval can double the rate of genetic gain at the same rate of inbreeding per generation, but with a higher rate ofInbreeding per year.
Journal ArticleDOI
Genetic analysis of body condition score of lactating Dutch Holstein and Red-and-White heifers.
TL;DR: It was concluded that BCS data collected by type classifiers can well be used for genetic evaluation and that genetic variation between animals for BCS-change patterns is a small component of the overall variation in BCS.
Journal ArticleDOI
Association of leptin gene polymorphisms with serum leptin concentration in dairy cows.

TL;DR: Surprisingly, associations were found during pregnancy, but not during lactation, which indicates that the leptin gene polymorphism could be more effective during pregnancy.
