Veterinary Medicine


The focus of veterinary1 medicine is on the science and art of treatment and prevention of disease and injury of nonhuman animals, especially domestic ones. Health care services provided by veterinarians are much needed and appreciated in both urban and rural areas. Households in the USA that own pets (dogs, cats, birds, etc.)2 (Figure 9.1) visit a veterinarian an average of three times per year (AVMA, 2002). Health care is devoted also to livestock (cattle, sheep, swine), horses and poultry, both in the clinic and during visits to farms and ranches.
