Bottom Line: This paper summarizes the results obtained by our working group from 2007 until 2012.The results elucidate the universal problem of foot pad dermatitis (FPD).Prevalence and degree showed a progressive development up to the age of 22-35 days, whereas 63.3% of the poults had foot pad alterations.

ABSTRACT
In a long term research project in Germany the influence of husbandry on the health of fattening turkeys (Study 1) as well as the influence of practiced rearing conditions on the health of turkey poults (Study 2) was examined in 24 farms and at the meat processing plant. In all examined rearing farms, litter samples for the determination of litter moisture were taken. This paper summarizes the results obtained by our working group from 2007 until 2012. The results elucidate the universal problem of foot pad dermatitis (FPD). Nearly 100% of the observed turkeys showed a clinically apparent FPD at the meat processing plant. Furthermore, skin lesions of the breast, especially breast buttons were diagnosed, particularly at the slaughterhouse. FPD was detected in the first week of the rearing phase. Prevalence and degree showed a progressive development up to the age of 22-35 days, whereas 63.3% of the poults had foot pad alterations. As even mild alterations in the foot pad condition can be indicators for suboptimal design of the rearing environment, especially high litter moisture, it is important to focus on the early rearing phase.

animals-03-00608-f002: Relative distribution of foot pad alterations per age group in male and female fattening turkeys. Results from the clinical examinations.

Mentions: Foot pad alterations were evaluated within individuals of all participating farms in terms of hyperkeratosis and epithelial necrosis up to ulcerative pododermatitis (Figure 2). An obvious age dependent degradation of the foot pad health status could be asserted in all fattening periods. Prevalence and severity of the skin alterations were therefore in general more pronounced in the 16th week of life than in the 6th or 11th week. However extensive epithelial necrosis could also be diagnosed in the 6th week (Figure 2). Generally the foot pad condition of turkey toms in the later fattening period was rated better than the condition of hens at the same age. While deep lesions on the foot pad surface in the 6th week were only seen in rare occasions, they were detected with a much higher prevalence in toms (14.7%, 95%-CI: [12.8–16.9]) than in hens (25.7%, 95%-CI: [23.3–28.2]) during the 11th week of life. The detection rate of profound skin alterations increased within the 16th week especially in male individuals up to 33.8% (95%‑CI: [31.1–36.7]). In turkey hens the prevalence of deep lesions with 60.0% (95%‑CI: [57.2–62.8]) was almost twice as high compared to the male individuals of the same age.
