Conventional and alternative housing systems for poultry--point of view of infectious disease medicine

The use of conventional battery cages for hens will be prohibited in Germany in 2007. Only few studies, however, have considered the differences between battery cages and alternative systems with regard to infectious diseases. The existing gaps in the current knowledge need to be closed by research and measures must be developed that will prevent the spread of viral, bacterial, and parasitic infections in alternative poultry housing systems.With regard to virus infections, avian influenza requires particular attention. Since wild birds, particularly anseriformes, represent a reservoir for avian influenza viruses, free-ranging poultry is much more at risk of infection than birds in closed hen-houses. Appropriate measures must prevent direct contact with wild birds and transmission via contaminated water, feed, or equipment. Several bacterial infections of poultry represent zoonoses. Salmonella and Campylobacter are considered as particularly important. To avoid a potential increase in the risk of infection for consumers due to poultry keeping systems that might favour infections with bacterial zoonotic agents, there is a special need for research in this area. With regard to parasitic infections, coccidioses may cause problems in alternative poultry housing systems, and lead to considerable economic consequences. The epidemiological situation concerning infections with Histomonas meleagridis needs to be analysed. Since all compounds that had been used for prophylactic or therapeutic purposes in the past have been banned, there is a need to develop new drugs which are safe for animals and humans.     

Complementary and alternative medicine for neurologic disorders

The use of complementary and alternative veterinary medicine in treating neurologic disorders has increased in popularity in response to advances in human alternative and integrative therapies. Neurolocalization of lesions to the brain, spinal cord, and neuromuscular systems is discussed, as well as the diagnostics and therapeutics used to treat such disorders. Emphasis is placed on integrative and alternative treatments for such neurologic diseases as seizures, cerebrovascular accidents, canine cognitive disorder, meningitis, intervertebral disc disease, fibrocartilagenous embolism, degenerative myelopathy, and myopathies. Thorough physical and neurologic examinations, establishment of a correct diagnosis, and integrative therapeutics are aimed at improving the overall quality of life of the veterinary patient.     

Complementary and alternative veterinary medicine and gastrointestinal disease

Gastrointestinal, hepatic, and pancreatic diseases provide a significant challenge to the veterinary practitioner. Specific causes and effective therapies can be elusive and sometimes frustrate both the animal caretaker and the veterinarian. The therapeutic options of a conventional veterinary practice are frequently limited and may come down to a decision of which is worse: the disease or the side effects of the treatment. This article provides information for the veterinary practitioner to consider for expanding his/her options. Acupuncture, herbal remedies, and homeopathy are not newly discovered modalities. They are old practices that are getting a fresh look from Western medicine as we seek new ways to better serve our patients and clients. The goal of this article is to provide the reader with many ideas and sufficient solid information to consider the use of these options. Specific therapies are suggested for numerous gastrointestinal and liver problems. Many of these may be used in conjunction with conventional therapies to aid in the healing process.     

Raising of fallow deer inside fences from the view of ethics and animal welfare

During the last years, keeping of fallow deer for the purpose of meat production has become a branch of industry that requires special attention from the view of ethology and animal protection. In zoological and judicial terms, the deer habituated to paddock keeping still belong to wild animals that are held captive. This paper describes the valid demands of fallow deer to its biotic and abiotic environment and deals in particular with population density, feeding practices, antlers amputation, killing and supervision.
