Necrotic enteritis in broiler chickens. III. Reproduction of the disease.
Lesions typical of necrotic enteritis could be produced experimentally in from 11-26% of broiler chickens consuming feed containing approximately 10(7) Clostridium perfringens per gram. Highest mortality was produced using isolates from field cases of necrotic enteritis which were reisolated from experimental cases in the laboratory. Penicillin in the drinking water at 100,000 I.U./litre completely prevented mortality whereas chloramphenicol at 110 mg/litre delayed the onset and reduced the number of deaths compared to controls.
