Influence of Duration of Simulated Transport on Plasma Stress Markers in the Calf*

Abstract

The effects of simulated transport of calves for 150 min on plasma cortisol, NEFA, glucose, and calcium were evaluated. Both cortisol and NEFA reached maximal values within 30-60 min, with no further increases during the transportation. Changes in glucose and calcium were not significant. The results indicate that in simulated transport, the duration per se is not a crucial factor in transport stress.
