¾TB, ½TB, ¼TB – horse groups with 75, 50 and 25% Thoroughbred ancestry within the parental and grandparental generations, respectively
Percentages marked with different letters significantly differ (according to Parker’s test) at p < 0.05: a, b, c - in columns (between different horse pedigree groups exposed to the same predator sound); x, y, z - in rows (between the same horse pedigree group at different test periods); *between the same horse pedigree group exposed to different predator sounds in analogical period of the test
