Faecal cortisol metabolites concentrations (ng/g) function of oral (A) and motor (B) stereotypic behaviours frequencies in horses from riding schools (study 1, N = 55). Samples were collected between 12:00 and 13:00, three times per subject: a sample on two different days, each 24 h after a day’s work and one sample 24 h after a day’s rest, then averaged. Original data are presented for clarity (data were log-transformed for analysis). Neither oral nor motor stereotypic behaviours frequencies predicted faecal cortisol metabolites concentrations (respectively F 1, 46 = 0.52, P = 0.47 and F 1, 49 = 0.23, P = 0.64).
