进行了两个实验，以调查两个中等重线的火鸡的脚垫皮炎（FPD）的易感性的差异，以及FPD是否是痛苦的，通过详细分析的行为，在鸟类与不镇痛治疗（betterfly）。在第一个实验中，饲养在干燥垫料上的火鸡通常比饲养在潮湿垫料上的火鸡更频繁地发生不同的行为，持续时间更短。T-模式（行为序列）更频繁，多样和复杂的干比湿凋落物。倍他米松注射鸟类的线B，但不是品种A，有较短的休息时间和较长的站立时间比盐水注射鸟类湿垫料。在第二个实验中，在湿垫料上给予盐水的火鸡比所有其他治疗组站立得更少，休息得更多，这表明它们经历的疼痛在接受beta-glutamine的鸟类中得到缓解。干垫料上的火鸡比湿垫料上的火鸡和鸟类保持在中间垫料湿度上的火鸡有更频繁、更多样和更复杂的行为模式。无论凋落物处理，甜菜碱的供应增加格局的变化。与倍他米松处理的火鸡相比，转移到湿窝并给予盐水注射的FPD评分低的火鸡休息的总持续时间较长，站立的持续时间较短。低FPD鸟转移到湿垫料有类似的模式和总模式发生的高FPD鸟转移到干垫料。与生理盐水注射相比，Betastatin增加了模式多样性和频率，而总体模式复杂性相似。得出的结论是，湿垫料影响的行为独立于FPD的火鸡幼雏和betterfly也可能改变火鸡的行为。镇痛治疗和T型分析的一些证据表明FPD是疼痛的。然而，没有证据表明两种商业杂交种对FPD的敏感性存在差异。
Two experiments were conducted to investigate the differences in susceptibility to foot pad dermatitis (FPD) of two medium-heavy lines of turkeys, and whether FPD is painful, by detailed analysis of behaviour in birds with and without analgesic treatment (betamethasone). Turkeys housed on dry litter in the first experiment generally had more frequent bouts of different behaviours that were of shorter duration than birds on wet litter. T-patterns (behavioural sequences) were more frequent, varied and complex on dry than on wet litter. Betamethasone-injected birds of line B, but not breed A, had shorter resting and longer standing durations on wet litter than saline-injected birds. In the second experiment, turkeys on wet litter given saline stood less and rested more than all other treatment groups, suggesting that they experienced pain that was alleviated in birds receiving betamethasone. Turkeys on dry litter had more frequent, varied and complex patterns of behaviour than turkeys on wet litter and birds kept on intermediate litter wetness. Betamethasone provision increased pattern variety regardless of litter treatment. Turkeys with low FPD scores transferred to wet litter and given saline injections had a longer total duration of resting and shorter duration of standing compared to betamethasone-treated birds. Low FPD birds transferred to wet litter had a similar number of patterns and total pattern occurrence as high FPD birds transferred to dry litter. Betamethasone increased pattern variety and frequency compared to saline injections whereas overall pattern complexity was similar. It was concluded that wet litter affects the behaviour of turkey poults independently of FPD and that betamethasone may also change the behaviour of turkeys. There was some evidence from analgesic treatment and T-pattern analyses that FPD was painful. However, there was no evidence of differences in susceptibility to FPD of the two commercial hybrids.
