Although it is acknowledged that blood collection at slaughter is not
optimal for detecting differences in blood indicators, it has to be understood
that this study was carried out under commercial conditions
restricting the design of the experiment. These conditions did not
allow physiological data to be measured prior to inducing stress for
use as a baseline, a situation not uncommon in animal research. Regardless, it should also be noted
that as shown by Averόs et al. in the absence of baseline data,
while there were no differences between treatments, the leukocyte,
neutrophil and lymphocyte counts were at levels indicative of stressful
events imposed on young bulls
