Cortisol concentration in horse saliva (means; µg/L) before and after exposure to predator vocalizations. Means marked with different letters significantly differ (according to Tukey’s HSD test) at p < 0.05: a, b, c -between different horse pedigree groups exposed to the same predator sound; x, y - between the same horse pedigree group at different test periods; * - between the same horse pedigree group exposed to different predator vocalizations

¾TB, ½TB, ¼TB – horse groups with 75%, 50% and 25% Thoroughbred ancestry within the parental and grandparental generations, respectively
