Summary
This summary is machine-generated.

Feed restriction in broiler chickens positively impacts the intestinal ecosystem. This dietary strategy significantly reduces the severity of necrotic enteritis, a common poultry disease.

Area of Science:

  • Poultry Science
  • Animal Nutrition
  • Avian Pathology

Background:

  • Necrotic enteritis, caused by Clostridium perfringens, is a significant disease in broiler production.
  • Subclinical infections can negatively impact gut health and performance.
  • Understanding dietary interventions like feed restriction is crucial for disease management.

Purpose of the Study:

  • To evaluate the impact of feed restriction on the intestinal ecosystem of broiler chickens.
  • To determine the efficacy of feed restriction in mitigating experimental necrotic enteritis.

Main Methods:

  • An experimental model for subclinical necrotic enteritis was established in Cobb 500 broiler chicks.
  • Birds were allocated to four groups: feed restricted, challenged, combined restriction and challenge, and control.
  • Intestinal lesions, digesta pH, viscosity, and cecal microbiota were analyzed.

Main Results:

  • Feed restriction significantly reduced necrotic enteritis lesion scores in challenged birds (P ≤ 0.05).
  • Dietary manipulation lowered small intestine pH and jejunal digesta viscosity.
  • Clostridium perfringens counts in the ceca were significantly decreased by feed restriction.

Conclusions:

  • Feed restriction beneficially modulates the intestinal ecosystem in broiler chickens.
  • This dietary approach offers significant protective effects against subclinical necrotic enteritis.
