Abstract

1豚房に2頭飼育した繁殖豚を5組用いて横臥行動に関する調査をした。飼育豚房 (8m<sup>2</sup>) はコンクリートコートの運動場 (17m<sup>2</sup>) 付設であった。季節に伴う繁殖豚の横臥行動の変化は春期 (豚舎温度8~19℃), 夏期 (21~35℃), 秋期 (8~24℃), 冬期 (0~9℃) に調査した。1日の横臥行動回数は夏期が11.1回で最も多く, 秋期が10.6回, 春期が9.4回, 冬期が6.3回であった (p<0.05)。1日の横臥行動時間は夏期が1,268±37分で最も長く, 次に, 秋期の1,267±26分, 春期の1,259±55分, 冬期の1,206±52分の順であり, 季節間で有意差 (p<0.01) が認あられた。同居繁殖豚の群横臥行動割合では冬期が93.2%で最も高く, 次に, 春期の85.6%, 秋期の71.4%, 夏期の30.8%の順であった (p<0.01)。このように, 2頭飼育繁殖豚の横臥行動では豚舎温度が下降すると横臥行動回数, 横臥行動時間が減少し, 群横臥行動割合が増加していた。

Lying behavior was examined on 5 groups of 2 sows fed in a pen. There was a concrete paddock (17 m<sup>2</sup>) attached to the pen (8 m<sup>2</sup>). Changes in lying behavior of sows fed in group (sows in group feeding) involved in different seasons were investigated at spring (temperature of pig house 8-19°C), summer (21-35°C), autumn (8-24°C) and winter (0-9°C). Frequency of lying behavior for a day was 11.1±4.3 times for summer, 10.6±2, 7 times for autumn, 9.4±3.2 times for spring and 6.3±2.7 times for winter (p<0.05). The longest duration of lying behavior for a day was 1.268±37 minutes in summer and followed by 1, 267±26 minutes for autumn, 1, 259±55 minutes for spring and 1, 206±52 minutes for winter, respectivly, which showed significant differences statistically (p<0.01). With respect to group lying behavior, the average percentage was 93.2±4.2% for winter, 85.6±7.7% for spring, 71.4±11.4% for autumn and 30.8±24.6% for summer (p<0.01). As seen from the above, frequency and duration for a day in lying behavior of sows fed in group (sows in group feeding) were decreased with fall in temperature of the pig house. Contrary to those results, the average percentage of group lying behavior was increased with low temperature of the pig house.
