E-book The Practice of Sheep Veterinary Medicine
There is a general perception amongst veterinary students and sheep producers that there are limited opportunities for a ‘sheep vet’ because individual sheep are generally of low value and the cost of veterinary involvement is too high. It is quite true that the value of individual sheep in commercial flocks is generally too low for sheep diseases with a low incidence to attract veterinary intervention. A whole flock of sheep, however, may consist of 100 to 1000 or more individuals and the cost of disease in such a large group of animals can justify significant levels of veterinary intervention. The practice of sheep veterinary medicine is usually concerned with the diagnosis of disease in a portion of the flock, perhaps the first few cases of an epidemic or a flare-up of an endemic disease, and the institution of preventive plans to protect the rest of the flock. The large number of animals at risk and the large productive value of the flock can justify significant expense on veterinary investigation and provide the veterinary practitioner with ample financial scope to display his or her diagnostic skills. It does require that the veterinarian approaches cases in a manner quite different from that used for individual sick animals. A good sheep veterinarian has excellent diagnostic skills, and a solid understanding of the epidemiology of sheep diseases, and can apply that knowledge in the context of often complex farm business operations. One would have to say that Australian sheep flocks are still under-serviced by private veterinary practitioners. The reasons for this are numerous. One major factor has been the emphasis on individual animal medicine in veterinary education and in most facets of clinical veterinary work. Sheep growers have perceived this, usually correctly, and used their veterinary practitioner for services to individual animals of value — rams, for example, and farm animals of other species such as cattle. Occasionally, sheep are presented at clinics for examination or necropsy but the determination of action required on the farm in the light of the diagnosis has been very much in the hands of the client rather than the veterinarian.2Many opportunities to make significant improvements in farm productivity are then lost because the veterinarian is insufficiently familiar with the details of the farm operation or perhaps lacks the confidence to follow through and review the outcome of any remedial action.
