Herzfrequenzen im Melkstand von konventionell und muttergebunden aufgezogenen Färsen

Summary

The aim of this study was to evaluate the influence of the rearing method on heart rates (as stress indicator) in the first days of lactation during milking. Heart rate was measured in two cows (K) and in eight heifers, four (F) reared with an automatic teat feeder, four (FKK) reared naturally by suckler- or foster cows. Heart rate was evaluated with a POLAR heart rate monitor on day one and nine of lactation during the milking procedure. The respective heart rates could be assigned to the events in the milking parlour via videoanalysis. Between the two heifer groups there were no physiologically relevant differences in heart rates on the two observed days. Both heifer groups showed higher heart rates on day one compared with day nine. Group K showed lower heart rates on both days.
