Abstract

The downer cow syndrome (DCS) is a challenging health issue in the dairy industry because of the high incidence of negative outcome. For practitioners dealing with DCS cases, it implies dealing with the cause of the problem but also with animal welfare concerns. Unfortunately, no cow-side test is available to provide an accurate prognosis of DCS cases in farm settings.

The presence of local and/or systemic hypoperfusion and myocardial lesions can lead to an increase in blood concentrations of biomarkers such as cardiac troponin I (cTnl) and L-lactate.

Since their blood concentrations can be determined using a validated cow-side portative unit, the objective of this study was to determine the cut-off values of these biomarkers for predicting survival in dairy cows affected by DCS.
