Abstract
"Many outbreaks of disease in swine herds can be avoided by use of management practices directed at disease prevention. Disease control is only one facet of a successful management program. New disease problems confront the swine industry where none previously existed. Recent changes in management and nutrition pose new problems. Larger numbers of swine are being raised in smaller areas, rations are designed to attain maximum growth, and it is possible to transport diseases and diseased animals great distances in a short time. Treatment of disease is not as effective or as economical as prevention. Prevention can be attained through management, which should include strict sanitation and immunization programs . National mortality rates indicate that 40% of the pigs farrowed are not marketed, and one-third of those farrowed are not weaned. This indicates where the greatest death loss occurs and where the greatest effort should be directed. It is difficult to measure losses other than deaths, but they do occur-abortions, poor conception rates, and lack of maximum -+growth and efficiency."--First page.B. L.
