Metabolic Clusters of Early-Lactating Dairy Cows Based on Blood -hydroxybutyrate Trajectories and Predicted from Milk Compounds

High-yielding dairy cows encounter metabolic chal- lenges in early lactation. Typically, β-hydroxybutyrate (BHB), measured at a specific time point is employed to diagnose the metabolic status of cows based on a prede- termined threshold. However, in early lactation, BHB is highly dynamic, and there is high interindividual vari- ability in its time profile. This could limit the effective- ness of the single measurement and threshold-based di- agnosis probably contributing to the disparities in...
