Résumé : | The heart rate and behaviour of 14 adult saddle horses, eight crib-biters and six normal controls, were investigated initiative the relationship between crib-biting and heart rate was investigated while the horses were undisturbed. The horses were tested when restrained with a lip twitch, and assessed when they were exposed suddenly to the rapid inflation of a balloon. The heart rate of the crib-biters during crib-biting was lower than during other behaviours. The crib-biters had a higher overall mean heart rate (P<0-05) suggesting that they may have had a higher basai sympathetic activity. After the application of the twitch, ail the horses had a transient increase in heart rate which returned to basai values more rapidly in the crib-biters. The crib-biters were less reactive to the lip twitch, five of the six investigated remaining calm, and after the release of the twitch, they spent more time nibbling (P<0-05) than the control horses. The crib-biters reacted more strongly to the inflation of the balloon (three of the six reacted), and after it had been inflated they spent more time walking in the box. |
