| 摘 要： | 对分娩圈中长白、大白母猪产前、产后的卧位、卧姿和卧向进行了观察,并就母猪对分娩圈空间的利用进行了研究。结果表明,母猪几乎不在采食区趴卧;长白母猪在趴卧区中央趴卧的机率约为50％,大白母猪在趴卧区四周趴卧的机率为67．54％～79．28％。母猪侧卧的机率极显著超过立卧(P<0．01);长白母猪哺乳期侧卧的机率明显高于妊娠期(P<0．01);但是大白母猪哺乳期侧卧的机率与妊娠期差异不显著(P>0．05)。母猪更愿意选择头朝外趴卧,且长白母猪的机率高于大白母猪,妊娠期的机率高于哺乳期(P<0．01)。

| Abstract: | Lying positions,lying posture,lying orientation of Landrace sows and Yorkshire sows were observed before and after parturition in farrowing pens. And the problem how sows make use of the space of farrowing pens was studied. The results showed that all sows in pen nearly did not lie in feeding area. The frequency of Landrace sows lying in the middle of farrowing pen was about 50% and that Yorkshire sows lying around farrowing pen was 67. 54% -79. 28%. It was found that the frequency of lateral recumbency was obviously higher than that of ventral recumbency (P<0. 01). In pen,the frequency of lateral recumbency in lactation period for Landrace sows was obviously higher than in pregnancy period (P<0. 01) , but it was not obvious for Yorkshire sows (P>0. 05). The results indicate that sows in pen prefer to lying outward,and Landrace lies outward more than Yorkshire, and the frequency of lying outward in pregnancy period is obviously more than that in lactation period (P<0. 01). |
