초록

This study was conducted to investigate the potential of toy provision for stress reduction, welfare improvement and toy preference in finishing pigs. Toy shape was expected to exert effects on stress related behaviors including fighting, bothering, and feed competition. Three different toy shapes (i.e. square, round, and oval) were given to groups of finishing pigs. A no toy control group was also included. The duration and frequency of abnormal behaviors and use time for toy preference were compared among groups. The duration and frequency of stress related behaviors was higher (p<0.01) among the non-toy-using finishing pigs on 20 minutes and 118 times than 16 minutes and 57 times of toy-using finishing pigs. Toy shape exerted no significant effects, however, toy use displayed a clear ability to reduce stress related behaviors among finishing pigs. Toy use time and shape both displayed no clear effect on the duration of stress related behaviors. These behaviors were most frequently displayed in the afternoons when the finishing pigs become most active, and were not affected by toy shape. Overall, the square shaped toy was used much longer (9.7 hours) and more frequently (566 times) in a 24 hour period by the finishing pigs (p<0.01). In conclusion, providing toys to finishing pigs reduces stress and stress related behaviors. This finding is expected to positively impact welfare and improve finishing pig productivity. Square shaped toys were most preferred by the finishing pigs, therefore adopting toys with square features is recommended.
