    Blood parameters predicted from milk spectra are candidate indicator traits of hyperketonemia—A retrospective study in the Italian Holstein population by S. Magro, M. De Marchi, M. Cassandro, R. Finocchiaro, A. Fabris, M. Marusi, A. Costa

    Published 2025-03-01
    “…Milk mid-infrared (MIR) spectroscopy has been successfully used for the prediction of several health traits in the last years, including blood metabolite concentrations, even though the model accuracy is moderate. In fact, MIR-predicted blood parameters are useful for population screening and may be used for selective breeding if they are heritable and genetically variable within a population. …”
