The relationship of claw lesions to housing was studied in 36 sow herds. Eighteen herds with loose housing of pregnant sows and 18 herds with confined (stalled or tethered) pregnant sows, were followed over a 12 month period. Fifteen of the loose housing herds had partly slatted concrete floors, while 3 herds had other types of flooring. The mean herd prevalence proportion of sows with major claw lesions in loose housing herds with partly slatted floors was about twice as high as in the herds with confined sows. In the only loose housing herd with deep litter based on straw, the prevalence proportion of sows with major claw lesions was lower than any of the other loose or confined herds. Within herds with loose sows on partly slatted floors, the prevalence proportion of sows with major claw lesions seemed to be higher in the loose housing compartment than in the farrowing compartment. The prevalence proportion of sows with major claw lesions did not differ between loose herds with plastic slats and loose herds with concrete slats.
在36个母猪群中研究了蹄爪损伤与猪舍环境的关系。18个群的怀孕母猪采用开放式猪舍饲养，另外18个群的怀孕母猪采用封闭式（限位栏或拴系式）饲养，跟踪观察12个月。15个开放式猪舍的猪群采用部分漏缝的水泥地面，3个猪群采用其他类型的地面。部分漏缝地面的开放式猪舍中，有严重蹄爪损伤的母猪在猪群中的平均患病率约为封闭式饲养猪群的两倍。在唯一采用厚垫草的开放式猪舍中，有严重蹄爪损伤的母猪患病率低于其他任何开放式或封闭式猪群。在部分漏缝地面的开放式猪舍中，有严重蹄爪损伤的母猪在开放式猪舍区域的患病率似乎高于分娩区域。采用塑料漏缝地板的开放式猪群和采用水泥漏缝地板的开放式猪群中，有严重蹄爪损伤的母猪患病率没有差异。
