Effects of rearing condition on plasma cortisol concentrations at the 4 different sampling times. Significant main effect of rearing condition (CON, CP, CRP > IRP, p<0.05). Significant rearing x sample interaction (Sample 1: CON > IP, p<0.05; Sample 3: CON, CP, CRP > IRP, all p<0.01; Sample 4: CP, CRP > IRP, both p<0.05).
