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1700 mm×1400 mm和1300 mm×1400 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 post mixed-group,24 fttening pie 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 sixes of I 700 mmx 1400 mm and 1300 mmX1400 mm respectively.High definition video cameras were used for continuously monitoring the behavior post mixed-group,including exploration,non-food fight,stand,nun,and lying.The resuls showed that group B had very significant or significant diference 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 dfference in stand behavior than goup A,1 to 2 h post mised-group(P<0.05 or P<0.01),while pigs in group A had significant or very signi-cant dference in lying behuvior than group B(P<0.05 or P<0.01).The resuls sugated that pen xize could have an efet 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 sltress post mixed-group,and to improve production perfomance and welfare level of pigs.
