Abstract

本報告は, 豚の運動と肉質の関係を追究するうえでの基礎的な知見を得ることを目的として, 豚の歩行速度, 運動持続距離および運動による一般的生理反応への影響について試験を行った。供試豚は肥育用の交雑種 (デカルブ×バークシャー) を4ヵ月齢3頭, 5ヵ月齢3頭, 6ヵ月齢3頭の計9頭を用いた。歩行運動は豚舎内に縦20m, 横10mの周回60mのコースを作製し, 1頭ずつ追い運動の形式で行った。豚の歩様は常歩, 速歩, 駆歩の3種に分類し, それぞれの速度を求めたところ, 常歩は時速3.5~3.8km, 速歩は時速7.4~9.7km, 駆歩は時速, 12.5~14.5kmであった。また, 常歩による歩行持続距離は4ヵ月齢で1,100m, 5ヵ月齢で1,500m, 6ヵ月齢で1,840mであった。歩行運動による心拍数, 呼吸数および直腸温への影響は300~600mの歩行運動後では月齢による大きな差は観られなかった。以上の結果から, 若齢肥育豚の常歩の歩行運動は時速4kmで1.5km程度と考えられる。

The present study was aimed at determining walking speed, the animal's durability for walking, and the effect of walking on the general physiological response as preliminary knowledge for future work relating to walking as exercise and the improvement of meat quality. Nine fattening crossbred swine (4, 5 and 6 months of age, respectively 3 heads) were used. The walking course was in the piggery and course size was follows; long side: 20m, short side: 10m, one lap: 60m. Walking exercise was conducted by the driving of each animal. Walking styles were classified as walk, gallop, and run and the speed of each style was: walk, 3.5-3.8km/hr; gallop, 7.4-9.7km/hr; run, 12.5-14.5km/hr. Walking durability varied with age: 4 months of age it was 1, 100m, at 5 months 1, 500m and at 6 months 1, 840m. There was no difference in the heart rate, respiratory rate or rectal temperature of swine which walked more than 300-600m. The swine used were given a sudden command to walk at our instructions, because they were generally maintained in a piggery. The present study suggested that a 1.5km walk at 4km/hr speed is a moderate exercise for young fattening swine.
