Area of Science:

  • Veterinary Medicine
  • Animal Science
  • Poultry Health

Background:

  • Digestive diseases in poultry disrupt normal cellular structure and function.
  • Economic factors and external influences can mimic or exacerbate digestive issues in commercial poultry.
  • Antinutritional factors and altered digestive secretions significantly impact nutrient absorption and gut health.

Purpose of the Study:

  • To elucidate the multifaceted pathogenesis of digestive diseases in poultry.
  • To highlight the interplay between cellular events, external factors, and the immune system in poultry digestive health.
  • To underscore the economic implications of digestive disease in commercial poultry production.

Main Methods:

  • Review of cellular events and reactions leading to deviations from normal digestive function.
  • Analysis of external factors, including nutrient density and feed refusal.
  • Examination of antinutritional factors, digestive secretions, infectious agents, toxins, and immune system influences.

Main Results:

  • Digestive disease pathogenesis involves cellular events, external factors, and antinutritional components.
  • Infectious agents and toxins cause significant injury, necessitating critical repair processes.
  • Impaired immune function exacerbates enteric diseases, affecting protozoan, bacterial, and viral infections.

Conclusions:

  • Poultry digestive diseases result from a complex interaction of cellular, nutritional, environmental, and immunological factors.
  • The consequences of digestive disease range from severe host injury to reduced animal performance.
  • Effective management of poultry digestive health requires a holistic approach considering all contributing factors.
