Broiler chicks were reared on either wet litter or dry litter to compare the development of footpad dermatitis (FPD). Broilers reared on wet litter first developed FPD at 14 days of age. Their FPD scores increased sharply after 21 days of age, reaching 2.92 at 42 days. In broilers reared on dry litter, FPD was first observed at 28 days of age, and the FPD score was only 0.70 at 42 days. When 21- or 28-day-old broilers that had been reared on wet litter and had developed FPD were moved to dry litter, the progression of FPD was suppressed or delayed. These results suggest that reducing litter moisture is effective in preventing FPD and suppressing disease progression.
将肉鸡饲养在潮湿垫料或干燥垫料上，以比较脚垫皮炎（FPD）的发展情况。饲养在潮湿垫料上的肉鸡在14日龄时首次出现FPD。它们的FPD评分在21日龄后急剧上升，42日龄时达到2.92。饲养在干燥垫料上的肉鸡在28日龄时首次观察到FPD，42日龄时FPD评分为0.70。当饲养在潮湿垫料上且已出现FPD的21日龄或28日龄肉鸡转移到干燥垫料上时，FPD的进展受到抑制或延迟。这些结果表明，降低垫料湿度对预防FPD和抑制疾病进展有效。
