Necrotic Enteritis

This acute “rot gut” disease causes severe intestinal damage in poultry. It is caused by toxins produced by the bacterium Clostridium perfringens, often after predisposing coccidiosis infections. Rapid detection is critical to control outbreaks. Prevention measures include good sanitation, stress reduction, proper nutrition, and coccidiosis control to maintain healthy intestinal integrity. Consult a veterinarian for advice on treatment and prevention.

Causes of Necrotic Enteritis

  • Overgrowth of Clostridium perfringens in the intestine.
  • Bacterial toxins damage the intestinal lining.
  • Coccidiosis infection can weaken the gut and contribute to C. perfringens overgrowth.

Clinical Signs of Necrotic Enteritis

  • Sudden onset of symptoms in previously healthy birds.
  • Acute depression and lethargy.
  • Diarrhea with dark, offensive fluid.
  • Reduced feed intake and weight loss.
  • Ruffled feathers and huddling.
  • High mortality, ranging from 2% to 30% in severe outbreaks.
  • Financial losses due to reduced growth and feed conversion efficiency.

Treatment of Necrotic Enteritis

  • Antibiotics: Bacitracin or virginiamycin administered in the feed or bacitracin in the drinking water.
  • Supportive therapy: Vitamins may enhance antibiotic effectiveness.
  • Prevention: Vaccination or medication in flocks with history of outbreaks.
  • Coccidiosis control: Address coccidiosis to prevent gut weakening and potential C. perfringens overgrowth.
