1. 进行了现场实验，以确定与生长火鸡发生足垫皮炎 (FPD) 相关的宏观和组织学变化。从 1 周龄到 8 周龄以及 10 周龄和 21 周龄，每周对两只受影响的火鸡和两只未受影响的火鸡进行取样。 2. 一周大时，具有 FPD（表面皮肤变色）外部症状的禽类表现出足垫外皮的异常细胞变化。随着鸡群年龄的增长，反应加剧，其中一个样本在三周时表现出完全发育的宏观病变。 3. 6周时已发生重大病理变化，所有具有外部病变迹象的火鸡均已完全形成微观炎症细胞病变。从 6 周龄起，病变越来越多，并且坏死更加明显。 4. 火鸡长到 4 周后，外部正常的足垫显示出损伤的微观证据。 5. 我们的结论是，FPD 损伤会在短时间内且在很小的时候就会变得严重。
1. A field experiment was conducted to identify the macroscopic and histological changes associated with the development of foot pad dermatitis (FPD) in growing turkeys. Two affected and two unaffected turkeys were sampled weekly from 1 to 8 and at 10 and 21 weeks of age. 2. At one week old, birds with external signs of FPD (surface skin discolouration) showed abnormal cellular changes of the foot pad integument. As the flock aged the reactions intensified, with one sample exhibiting a fully developed macroscopic lesion at 3 weeks. 3. Major pathological changes had occurred by 6 weeks and all turkeys with external signs of lesions had fully developed microscopic inflammatory cellular lesions. From 6 weeks of age onwards lesions were increasingly numerous and became more overtly necrotic. 4. Externally normal foot pads showed microscopic evidence of lesions after the turkeys reached 4 weeks. 5. We conclude that FPD lesions become severe over a short period of time and at a very early age.
