Turkeys are equally susceptible to foot pad dermatitis from 1 to 10 weeks of age and foot pad scores were minimized when litter moisture was less than 30%.

采用两个随机区组试验，研究了垫料含水量和日龄对生长期雌性火鸡足垫皮炎（FPD）发生的影响。在实验开始时，将围栏用新鲜的木屑乱扔，每天更换两次排泄物和污染的垫料，以保持垫料清洁。在实验1中，对鸟类（n = 5只/围栏）进行6天的水量增加，以产生不同的枯枝落叶含水量。在实验2中，在7，21，42和70 d的高凋落物水分6 d的FPD的影响进行了评估。FPD，食物摄入量，BW增益，垫料水分，垫料pH值，和行为的分数进行了评估后6天湿干，干净的木屑垫料相比。线性效应被发现增加枯枝落叶层水分平均脚得分。平均足部评分随年龄增加转移到湿窝，但年龄的影响相对较小。体重增加在湿和干处理相似，而饲料摄入量较高，保持在湿垫料与干垫料相比，火鸡。结果是一致的结论，即高垫料水分是FPD的主要原因，火鸡是同样敏感的7至70日龄。
Two randomized block experiments were conducted to determine the effects of litter moisture and age on the development of foot pad dermatitis (FPD) in female growing turkeys. Pens were littered with fresh wood shavings at the start of the experiments and excreta and soiled litter were replaced twice daily to maintain clean litter. In experiment 1 the birds (n = 5/pen) were subjected to increasing quantities of water to produce different litter moisture contents for 6 d. In experiment 2 the effects on FPD of high litter moisture for 6 d at 7, 21, 42, and 70 d were assessed. Scores for FPD, food intake, BW gain, litter moisture, litter pH, and behavior were assessed after 6 d on wet compared with dry, clean wood shavings litter. A linear effect was found of increasing litter moisture on mean foot score. Mean foot score increased with age on transfer to wet litter but the effect of age was relatively small. Body weight gains were similar in wet and dry treatments whereas feed intake was higher in turkeys kept on wet litter compared with dry litter. The results are consistent with the conclusion that high litter moisture is the primary cause of FPD and that turkeys are similarly susceptible from 7 to 70 d of age.
