 note = {挙肢を行わない簡便な蹄病診断法の確立を目的として，３軸加速度センサと跛行スコアを組み合わせて，牛の跛行の主な原因となっている蹄底潰瘍および白帯病の摘発を試みた．その結果，正常牛の歩様は外蹄から着地し内蹄で踏み切り，重心が左右にぶれない安定した歩様であるため，跛行スコアは１，加速度変量総和は3622±227m/s2で安定していた．蹄底潰瘍罹患牛は歩行時に罹患肢の内蹄と外蹄を同時に着地し，跛行スコアは２〜３，加速度変量総和は7225±877m/s2であり，正常牛に比べて有意(p<0.01）な高値を示した．白帯病罹患牛の加速度変量総和は正常牛と同様の値を示したが，跛行スコアは３〜４であった．よって加速度センサと跛行スコアを組み合わせることにより蹄底潰瘍と白帯病を摘発できる可能性が示唆された．, In order to establish an easier detection method for hoof diseases without raising hooves, we examined the effectiveness of triaxial accelerometer and gait score in detection of sole ulcer and white line disease. Cattle with healthy hooves placed their hooves on the ground using the lateral claws and then pushed off using their inner claws, and their locomotion score were classified in score 1. The mean vector sum of acceleration of these healthy cattle was 3622±227m/s2. Cattle with sole ulcer set their affected hooves on the ground using both of the inner and lateral claws, locomotion score were classified in score 2 or 3, and the mean vector sum of acceleration was 7225±877m/s2, which was
significantly higher than that of healthy cattle（ p < 0.01）. Cattle with white line disease showed a mean vector sum of acceleration similar to that of healthy cattle, though their locomotion score were classified in score 3 or 4. These results suggested the usefulness of the combination of vector sum of acceleration and gait score for detection of sole ulcer and white line disease in cattle.},
