摘要：Flight and avoidance reactions from human were examined using 168 postweaning Thoroughbred foals in 22 breeding farms. Further 114 yearlings of 168 foals were tested in the following summer. The foal handlings by the stabler were asked in questionnaire. The relationship between the behavioural reactions and the foal handling frequencies was analyzed. The flight reaction was estimated as the distance from the animal to a stranger when the animal began to flight away from his approach. The avoidance scores were set up from (1) (not resistant) to (5) (touch rejection) from human touching. In the stabler questionnaire, handling frequencies of "body brushing", "rectal temperature measurement", "hoof cleaning", and "stall cleaning" in the early nursing period were asked. The handling frequencies were scored from (1) (not done) to (5) (every day). In the preliminary test, a measurement reliability of the flight distance and the avoidance score was confirmed. The mean flight distances were 0.56 m and 0.27 m in the postweaning foals and the yearlings, respectively. Touch-avoidance scores of the highest frequency were (3) and (2) in the postweaning foals and the yearlings, respectively. As the results of Spearman's rank-correlation analysis, "body brushing" showed highly negative relationships with "flight distance" (ρ=-0.31, P<0.001) and "avoidance score" (ρ=-0.37, P<0.001) in the postweaning foals. In the yearlings, "hoof cleaning" also showed significantly negative relationships with these behavioural indices (ρ=-0.24, P<0.01; ρ=-0.22, P<0.01, respectively).
