饲喂次数对育肥猪与采食有关行为规癖的影响

研究了不同饲喂次数对育肥猪行为的影响。选择24头长大二元生长肥育母猪（平均初始体重60．01±0．96kg），分为3个处理，每个处理8个重复，每个重复一头猪，单栏饲养。3个处理分别为：（1）日饲喂2次；（2）日饲喂3次；（3）日饲喂4次。采用瞬时记录法，在采食期间观察，试验期为2个月。结果表明：育肥猪采食期间，日饲喂2次比日饲喂3次、4次有更强的采食动机，单次采食概率大，行为规癖较少。

Effects of Different Feeding Times on Feed-Related Behaviour Stereotypies of Finishing Pigs

This experiment was carried out to study the effects of different feeding times on behaviour of growing pigs. 24 growing--finishing female pigs （average initial body weight 60.01±0.96kg） were divided randomly into four treatments with each treatment including 8 repetitions. Each redpetition included a pig. There was a pig in one pen. Treatment one were fed twice each day; Treatment two, three times each day. Treatment 3, three times each day. Behaviour was recorded by direct observation during the feeding time. The whole experimental period is two months. The results showed that during the feeding time, the intake motivation and single feeding frequency of feeding twice of finishing pigs were much higher than the others, but the behaviour stereotyoies was lower.
