From: Cardiovascular, endocrine and behavioural responses to suckling and permanent separation in goats
Plasma concentrations of cortisol and β-endorphin during separation (Study 3). Means (± SEM) of plasma concentrations of cortisol and β-endorphin before, during and after separation (SEP) in seven goats. Blood samples were taken 30 and 5 minutes before separation, during separation at 10.30 h, and 5, 15, 30, 60 and 120 minutes after separation. ** = P ≤ 0.01 indicates significant difference compared to the first sample (-30 minutes).
