摘  要：
为了研究限位栏饲养模式和群养模式对母猪在分娩前和分娩后行为的影响,选取限位栏饲养模式下的大白和杜洛克怀孕母猪各18头、群养模式下的大白和杜洛克怀孕母猪各10头,记录在分娩前2周以及分娩后3周内的母猪行为,分析母猪分娩前后的行为差异以及不同饲养模式对母猪行为的影响.结果表明,所有母猪行为中,趴卧时间均占观察时间比例最高(>85%),分娩后母猪趴卧时间增长(>93%),而分娩前犬坐和站立时间占观察时间比例相对较少(<3.5%和<11.5%),分娩后其占观察时间比例更小(<2.2%和<4.3%).在两种饲养模式下,两个品种母猪在分娩前的站立时间以及舔、嗅和针对饮水器等行为的频率均显著高于分娩后(P<0.05),分娩后的趴卧时间和针对饲槽的行为频率则显著更高(P<0.05),表明在两种饲养模式下,母猪在分娩前与后的行为均表现出显著差异,而杜洛克母猪分娩前与后的行为差异更明显.在分娩前,限位栏饲养的两个品种母猪的啃栏和针对饮水器行为的频率显著高于群养母猪(P<0.05),而分娩后群养大白和杜洛克母猪的趴窝行为均显著高于限位栏饲养的大白和杜洛克母猪(P<0.05),表明限位栏饲养的母猪较群养母猪规癖行为发生频率更高,福利水平较差.

摘  要：
The aim of this study was to analyze the effects of group housing and stall condition modes on behavior of sows before and after delivery. In the study, 36 pregnant sows were selected under the stall conditions(18 Yorkshires and 18 Durocs), 20 pregnant sows were selected under the group housing(10 Yorkshires and 10 Durocs), and using the camera to record them for 2 weeks before delivery and 3 weeks after delivery. The behavioral differences of sows before and after delivery and the effects of different feeding patterns on sows behavior were analyzed. In all the behaviors, the duration of lying was the longest in the observation time(>85%), and the sow's lying duration increased after delivery(>93%). However, the ratio of sitting and standing time before delivery was relatively small(<3.5% and <11.5%), and the proportion of observation time was smaller after delivery(<2.2% and <4.3%). In two different feeding modes, standing time and the frequency of licking, sniffing and drinking fountains of all sows before delivery was significantly higher than that after delivery(P<0.05), and postpartum lying time and manger frequency were significantly higher(P<0.05), suggesting a significant difference in the behavior of sows before and after delivery in both group housing and stall conditions. Prior to delivery, the behavior of biting bars and aiming at drinker under the stall conditions was significantly higher than that of the group housing(P<0.05). After delivery, lying behavior of the sows raised in the group housing, which was significantly higher than that in the stall conditions(P<0.05), indicating that the sows raised in the stall conditions had higher frequency of stereotypic behavior than group housing sows, with poor welfare.
