Abstract

Economic losses, increased cost and/or decreased revenue, associated with disease outbreaks or parasites in swine are significant [2, 3 and 4]. Knowledge of economic implications of disease presence is needed in making hog production health management decisions. The adverse economic and production effi^ts of internal and external parasitism. in swine are well-recognized. In the. past, data limitations have made it difficult to quantify the effect of parasite control on grow-finish and reproduction performance in swine. Average daily gain decreases from 5-15% from mange infestations have been reported by several, researchers. Similarly, internal parasitism has been demonstrated to cause substantial economic losses without precipitating significant clinical disease or death of affected swine. These insidious losses cause millions of dollars in losses to the United States and world swine industry each year.
