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.

(a) Category 0: no abnormalities detected. (b) Category 1: hyperkeratosis, moderate hypertrophy of the plantar skin. (c) Category 2: high-grade hyperkeratosis with adhesive dirt. (d) Category 3: superficial lesions, epithelial necrosis. (e) Category 4: profound lesions of the plantar skin (also see Table 1).

(c) Category 2: high-grade hyperkeratosis with adhesive dirt. (d) Category 3: superficial lesions, epithelial necrosis. (e) Category 4: profound lesions of the plantar skin (also see Table 1).

Mentions: One of the fundamental results of the study during the fattening phase was that up to 45% of the examined turkeys already showed alterations in the foot pad condition at the early age of six weeks shortly after relocation from the early rearing phase into a new stable (see results section). Because of this finding, analogous examinations took place during the early rearing phase in the following study. Apart from the prevalence of foot pad alterations the main focus now was additionally set on selected husbandry conditions, especially on the litter quality and climate parameters. Data assessment was carried out equally on 24 turkey farms. Altogether 5,531 beak trimmed turkey poults (3,131 male, 2,400 female) solely of the turkey strain B.U.T.6 were examined. These examinations took place twice during the early rearing phase [Days 3 to 5 (shortly after the delivery from the hatchery) and Days 22 to 35 (shortly before relocation)]. In general this scheme was repeated during a second rearing period per farm. Because of overlapping time schedules in two farms solely one rearing period could be evaluated. In general 60 randomly picked poults per flock were examined per visit especially concerning the foot pad health status (Figure 1) in accordance to the scoring scheme in Table 1. For these examinations 20 poults each were picked from the front, the middle and the far end of every barn. When ring scheme rearing was practiced during the first visit, 20 poults stemming from the same ring and from the front, middle and rear barn area were included in the examinations. Poults seperated from the flock due to a physical illness were generally not used for examination.
