摘要
为了研究圏栏面积对猪混群后行为的影响,试验选择育肥猪24头,随机分为A组和B组,每组3个重复,每个重复4头猪,分别在面积为1 700 mm×1 400 mm和1 300 mm×1 400 mm的圈栏内饲养,采用高清视频摄像头持续监测猪混群后的探索、非饮食争斗、站立、跑、躺卧等行为。结果表明：猪混群0.5～1 h B组圈栏内非饮食争斗、跑的行为达到极显著或显著水平（P〈0.01或P〈0.05）;混群1～2 h B组圈栏内猪群站立行为显著或极显著高于A组（P〈0.05或P〈0.01）,而A组圈栏内猪群躺卧行为则显著或极显著高于B组（P〈0.05或P〈0.01）。说明圈栏面积会影响猪混群后的行为,养猪生产中应合理调整饲养密度,以减少猪混群产生的争斗,从而降低混群带来的应激,提高猪群的生产性能和福利水平。
In order to research the effect of pen size on the behavior of pigs pest mixed-group,24 fattening pigs were selected in this experiment and were divided into groups A and B,with 3 replicates per group and 4 pigs per replicate,and two groups were raised in pen sizes of 1 700 mm×1 400 mm and 1 300 mm× 1 400 mm respectively. High definition video cameras were used for continuously monitoring the behavior post mixed- group, including exploration, non-food fight, stand, run, and lying. The results showed that group B had very significant or significant difference in non-food fight or run behavior respectively 0. 5 to 1 h post mixed-group（ P〈0. 01 or P〈0.05）. Group B had significant or very significant difference in stand behavior than group A, 1 to 2 h post mixed-group （ P〈0. 05 or P〈0. 01 ） , while pigs in group A had significant or very significant difference in lying behavior than group B （P〈0. 05 or P〈0. 01 ）. The reresults suggested that pen size could have an effect on the behavior of pigs post mixed-group, and breeding density should be adjusted reasonably in pig production in order to decrease pig fighting behavior post mixed-group and to reduce the stress post mixed-group, and to improve production performance and welfare level of pigs.
