Lameness and foot disorders are major health and welfare issues in intensive swine production systems. They are exacerbated when sows are housed in large groups on slatted concrete floors during gestation. Our study aimed to assess the effect of rubber mats in the lying area of the gestation pen on lameness and leg health in gestating sows housed in large pens in commercial conditions. The study was conducted on three commercial farms over two successive gestations. A total of 582 Large White × Landrace sows, housed in 10 static groups, were enrolled: 5 groups in pens with rubber mats and 5 groups on slatted concrete floors. Lameness, bursitis, leg injuries, claw growth defects and claw lesions were measured at the beginning, middle and end of each gestation period. The rubber mats decreased the risk of suffering from bursitis, but had no effect on the risk of lameness, leg injuries, claw growth defects or claw lesions. Sows housed on rubber mats were heavily soiled compared with those on slatted concrete floors because the mats were not perforated for slurry evacuation. Locomotion disorders and foot lesions remained prevalent despite the rubber mats in the lying area of the gestation pens, but adding rubber mats in service rooms and farrowing crates may produce better results.
跛行和足部疾病是集约化养猪生产系统中的主要健康和福利问题。当母猪在妊娠期被成群饲养在有缝隙的水泥地面上时，这些问题会更加严重。我们的研究旨在评估妊娠栏躺卧区的橡胶垫对在商业条件下饲养在大栏中的妊娠母猪跛行和腿部健康的影响。该研究在三个商业农场连续两个妊娠期进行。总共纳入了582头大白×长白母猪，分为10个固定组：5组饲养在有橡胶垫的栏中，5组饲养在有缝隙的水泥地面上。在每个妊娠期的开始、中期和末期测量跛行、滑囊炎、腿部损伤、爪生长缺陷和爪损伤情况。橡胶垫降低了患滑囊炎的风险，但对跛行、腿部损伤、爪生长缺陷或爪损伤的风险没有影响。与饲养在有缝隙水泥地面上的母猪相比，饲养在橡胶垫上的母猪身上污垢较多，因为橡胶垫没有用于粪便排出的穿孔。尽管妊娠栏躺卧区有橡胶垫，但运动障碍和足部损伤仍然普遍存在，不过在服务室和产仔箱中添加橡胶垫可能会产生更好的效果。
