The associations between individual foot lesions and different types of floor were investigated in 4038 finishing pigs on 21 units. The overall prevalence of foot lesions was 93.8 per cent and the prevalence ranged from 79.4 per cent to 100 per cent on different units. Analysis showed that pigs kept on bedded floors, with either sparse or deep straw, had a lower prevalence of sole erosions, heel erosions and heel flaps and a higher prevalence of white line lesions, false sand cracks, wall separations and toe erosions than pigs kept on bare solid concrete floors. Partially slatted floors were associated with an increased prevalence of heel erosions, heel flaps, white line lesions, wall separations and false sand cracks, and totally slatted floors were associated with an increased prevalence of sole erosions and heel flaps.
在21个猪场的4038头育肥猪中，研究了个体足部病变与不同类型地面之间的关联。足部病变的总体患病率为93.8%，不同猪场的患病率在79.4%至100%之间。分析表明，与饲养在光秃实心混凝土地面上的猪相比，饲养在铺垫有稀疏或厚垫草的地面上的猪，其 sole erosions（此处sole可能是指猪的脚掌底部，暂直译为“脚掌底部糜烂”）、heel erosions（足跟糜烂）和heel flaps（足跟皮瓣）的患病率较低，而白线病变、假性砂裂、蹄壁分离和趾部糜烂的患病率较高。部分漏缝地板与足跟糜烂、足跟皮瓣、白线病变、蹄壁分离和假性砂裂的患病率增加有关，全漏缝地板与脚掌底部糜烂和足跟皮瓣的患病率增加有关。
