Abstract

Stress has a negative impact on livestock production. Several physiological indicators currently exist to identify when animals are experiencing stress. Recently it has been suggested that the site of blood sampling may influence clinical pathologic parameters in rodents (Nasir et al., 1996). Because of the difficulty interpreting multiple physi-ological measures of stress and their high variation within animals we conducted a study to 1) determine the effect of blood sampling site on physiological measures of stress in dairy cows and 2) identify new quantifiable indicators of stress.
