Daily basal salivary cortisol level and salivary cortisol response to stimulus presentations of 5 dairy goats. The daily baseline cortisol (ng.mL-1; mean ± SEM) was calculated as mean of the cortisol measurements preceding presentation of non-neutral stimuli (Table 1, last column), whereas the salivary cortisol response represents the mean of all cortisol measurements of a day, following the first stimulus presentation. *: One sample t-statistics on difference score between basal cortisol and cortisone response to stimuli, p < 0.05.
