  •  QTL Experiment in Brief
    Animals:Animals were US Holstein cows.
     Breeds associated:
    Design:Genotypes for 78,964 original and imputed SNPs were available for the study population. A total of 75,524 SNPs were used in a GWAS for age at first calving.
    Analysis:GWAS was performed using an approximate generalized least-squares method.
