Behavior: coprophagia

pequis

Synonym(s): Coprophagy


Introduction

  • Coprophagia (consumption of feces) is considered to be normal behavior in horses, especially in foals.
  • Coprophagia has been observed in adult horses maintained on a protein-deficient diet .
  • Has also been associated with motor neurone disease.
  • Coprophagia may result in superinfection with internal parasites.

Pathogenesis

Etiology

  • Has been reported to be associated with protein-deficient diet in adults.

Predisposing factors

General
  • Foals; may be response to maternal pheromones.
  • Protein-deficient diet.
  • Possibly other nutritional deficiency.

Pathophysiology

  • May be induced by pheromones; foals tend to eat feces of their mother.
  • Thought to be normal behavior in foals.
  • May be due to response to maternal feromones.
  • Possible functions:
    • May introduce normal gut flora to foals.
    • Deoxycholic acid in feces may provide protection against enteritis.
    • Deoxycholic acid may be involved in myelination of nervous system.
    • Pheromones may accelerate growth or sexual development.
    • Compensation for nutrient deficiency.
  • May also result from motor neurone disease .

Timecourse

  • Most common in first 2 months of life.
