performing roles which are also found in human medicine, such as practitioners dealing with musculoskeletal disorders, including osteopaths, chiropractors, and physiotherapists. Some roles are specific to animals, but which have parallels in human society, such as animal grooming and animal massage. Some roles are specific to a species or group of animals, such as farriers, who are involved in the shoeing of horses, and in many cases have a major role to play in ensuring the medical fitness of horses. Veterinary research Veterinary research includes prevention, control, diagnosis, and treatment of diseases of animals, and basic biology, welfare, and care of animals. Veterinary research transcends species boundaries and includes the study of spontaneously occurring and experimentally induced models of both human and animal diseases and research at human-animal interfaces, such as food safety, wildlife and ecosystem health, zoonotic diseases, and public policy. By value the most important Animal Health pharmaceutical supplier worldwide is by far Zoetis (United States). Clinical veterinary research As in medicine, randomized controlled trials also are fundamental in veterinary medicine to establish the effectiveness of a treatment. Clinical veterinary research is far behind human medical research, though, with fewer randomized controlled trials, that have a lower quality and are mostly focused on research animals. Possible improvement consists in creation of networks for inclusion of private veterinary practices in randomized controlled trials. No studies exist on the effect of community animal health services on improving household wealth and the health status of low-income farmers. The first recorded use of regenerative stem-cell therapy to treat lesions in a wild animal occurred in 2011 in Brazil. On that occasion, the used stem cells to treat a maned wolf who had been run over by a car, which was later returned, fully recovered, to nature.
