  •  QTL Experiment in Brief
    Animals:Ten larger half-sib families from the Dairy Bull DNA Repository consisting of 1414 bulls were selected for QTL detection using the granddaughter design.
     Breeds associated:
    n/a
    Design:Multiple traits were measured falling into 4 groups: the udder group, the body form group, the feet and legs group, and the dairy capacity group.
    Analysis:There were 406 markers used for genotyping. Data were analyzed using a regression approach to detect QTL within and across families.
