ASCARIDIA DISSIMILIS LARVAL MIGRATION ASSOCIATED WITH ENTERITIS AND LOW MARKET WEIGHTS IN MEAT TURKEYS

A meat turkey ranch had a history of producing flocks with low market weights. Live bird samples and environmental samples from the ranch we re collected over a period of eight months and analyzed at the Califor nia Veterinary Diagnostic Laboratory System-Turlock Branch. The diseas e condition consistently present was enteritis associated with Ascarid ia dissimilis infection in birds from growout houses. After aggressive control measures for A. dissimilis were implemented, subsequent flock s reached expected market weights.
