以上より,竹製遊具供与は舎飼い肥育豚の行動を多様化させるエンリッチメント素材の1つになり得る可能性が示唆された。, We evaluated the effects of providing a bamboo log as a toy on the growth and behavior of finishing hogs, at 15-29 weeks of age, in the pen.  Four pigs were provided the bamboo log (bamboo group) whereas four were not(controlgroup). Both groups were fed a commercial diet, which was available ad libitum. The growth rate and feed efficiency of the bamboo group were similar to those of the control group. Immediately after offering the bamboo log, the bamboo group spent significantly less time in resting behavior and more frequently showed fighting behavior than the  control group at 15 weeks of age (P<0.05). Significant differences in resting and fighting behaviors between treatments were not observed after 15 weeks of age. The frequency of total licking and chewing behaviors in the bamboo group was significantly higher than that of the control group at 15 and 19 weeks of age (P<0.05). The frequency of rooting-like behavior towards the floor and bamboo in the bamboo group was significantly higher than that in the control group throughout the observation period after 15 weeks of age. In conclusion, these results suggest that providing a bamboo log as a toy is a useful enrichment material that can diversify the behavior of finishing hogs.},
