The prevention of experimentally induced necrotic enteritis in chickens by avoparcin.
Four groups of about seventy 2-week-old broiler chickens were challenged with a Clostridium perfringens Type A isolate. Inclusion of avoparcin at 20 ppm in feed prevented necrotic enteritis in one group, but 10 ppm was only marginally effective. Bacitracin at 110 ppm also prevented the disease. Necrotic enteritis was successfully reproduced in untreated control birds.
