| The body size and weight of 584 Banei draft racehorses at Obihiro Racing Stable in Hokkaido, Japan, was investigated. Almost all the animals (94.7%) were cross-breed heavy draft horses; there were a few Percheron and Percheron grade (4.8%) and a Belgian breed (0.5%). The ages of the animals ranged from 2 to 10 years. Males accounted for 80.3%, females for 17.5%, and 2.2% were castrated. The mean body measurements of 2-year-old Banei draft racehorses were significantly smaller than those of the 3-to 4-year-old or 5-to 10-year-old horses. Hip width, croup width, and rump length of females were greater than those of males. In contrast, males had greater chest width and cannon bone circumference than females. Significant relationships among almost all body... |

| ばんえい競馬において，第2障害越えの成否は競走 結果に大きな影響を及ぼす.本研究では，ばんえい競 走馬が第2障害を登坂するときの運動の特徴を数値化 し，それらの値と競走結果との関係を検討した.延べ 37頭の競走馬について登坂運動時のフォームをデジ タルビデオカメラで録画した.画像解析プログラムを 用い馬体水平線と胴引との角度を求め(胴引き角度)， その角度から馬の腰の上下運動を数値化した.競走結 果(競走タイム，着順，登坂時間，登坂順位)に影響 を及ぼす要因として，登板時の停止の有無，歩法(常 歩 : 駈歩)，および胴引き角度(18.3度以上 : 以下)と 年齢(2歳 : 3歳以上)の交互作用について分析した. その結果，登坂時に停止しない馬の競走結果が良く， また2歳馬においては胴引き角度の大きい(腰の高い) 馬が，一方3歳以上の馬においては胴引き角度の小 さい(腰の低い)馬の競走結呆が良い傾向が示された. 2歳馬と3歳以上の馬で異なる結果が示されたのは， ばんえい重量が登坂運動時のフォームに影響を及ぼ し，さらにそれが競走結果にも影響するためではない かと推察した. |

| This study evaluated the possibility of decreasing defecation in a bedding area by inducing a heifer to visit a feeding station within a few minutes or immediately after standing. An experimental paddock (11.3 x 6 .8m) was made outdoors. Half of the paddock was roofed and bedded with straw to form a resting area. A feeding station was situated in the remaining area of the paddock，which was designated as the feeding area. Six Holstein heifers，the test subjects，were grouped together in the paddock. A standing detection device was developed and attached to the heifer's left hind leg. The feeding station had an antenna that identified the heifer carrying the ID-tag when it entered the station. This experiment included control period and an experimental... |
