Influence of duration of simulated transport on plasma stress markers in the calf

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.
