The objective of today's food animal enterprise is to produce a quality product while at the same time providing maximum economic return to the producer. Many factors are involved, including herd health programs, which work to maintain animal health and to decrease economic losses due to disease. A herd health preventive medicine program will increase the costs of production, but it will increase the economic returns if the level of performance is improved.
