Within the framework of a cooperative research project, turkey health as well as numerous aspects of animal welfare were examined in various intensive commercial farms with varying rearing forms. The present study demonstrates the prevalence of skin injuries concerning living animals as well as carcasses of slaughtered turkeys of both sexes. Although all turkeys were debeaked, prevalences of skin injuries at a value of 12.8% with male turkeys and 13.8% with female turkeys could be found at the age of 16 weeks. Within the scope of medically inspections skin injuries were mainly established in the head region, especially the snood as well as in the region of the back. By means of their clinical picture pecking wounds and scratch injuries could be distinguished. Skin lesion produced primary as a result of scratching the skin surface, could be enlarged by the animal itself or by conspecifics by beak pecking, especially after bleeding, in spite of debeaked upper beak. Injuries in the head region, especially of the snood, could be explained mainly as a result of pecking by conspecifics by reason of their clinical picture and were found mainly in male turkeys. Skin injuries in the region of the back, especially at the coxal tuberosity, were identified primarily as scratch marks. They were found mainly in female turkeys. A statistically significant correlation of the injury prevalence to particular husbandry parameters discussed in the literature as "predisposing" or "limiting" factors (e.g., population density, light regime or offer of employment material) could not be established in this study. At the meat inspection fresh scratching injuries at the chest and the hind legs were diagnosed most often. Especially fresh injuries of the carcass point to a misguided behaviour of the staff concerning animal handling during loading and transport which is not conform to animal welfare.

Within the framework of a cooperative research project, sponsored by the Federal Ministry of Food, Agriculture and Consumer Protection in Germany (BMELV), turkey health as well as numerous aspects of animal welfare in various intensive commercial farms with varying rearing forms were examined. For this purpose extensive documentation of flock management and health status information was conducted over the past two years at the farms. Additional information was ascertained from the carcasses at the slaughterhouse. The first results of this study, which look at flock management, will be presented here. Upon reviewing the questionnaires, it is clear that on one hand almost all farmers orientate there stocking rate upon the allowed limits, on the other hand, however, when considering national general requirements, which are very important parameters thatargely influence animal health (i. e. litter quality and care of sick/injured animals) farmer compliance lacks. Especially the litter quality, which, among other parameters, plays a very important role in food pad health, proved to be unsatisfactory. Unfortunately, no instruments are available that measure the litter quality, yet. The status of footpad health was a major problem in all the rearing systems. However, the prevalence of epithelial necrosis and deep skin lesions varied immensely among different flocks of the same age.
