Nutrition: probiotics

pequis

Introduction

  • Probiotics have been defined as 'a live microbial feed supplement which beneficially affects the host animal by improving its intestinal microbial balance'.
  • Within the EU only registered live culture strains may be fed to animals.

Equine digestive system

  • Indigenous gut microflora:
    • Composition incorporates a population of 400 bacterial species.
    • Symbiotic relationship undergoes a constant selection and fluctuation.
  • Role:
    • Digestive (fermentation of fiber and starch).
    • Protective (prevention of establishment of potential pathogenic micro-organisms).
  • Factors inducing changes of stable gut microflora are influenced by dietary and environmental conditions the most significant of which include:
    • Stress: transport, birth, parturition, castration or other surgery, performance/competition, illness or injury, fear. Within the gut the trend during stress is for Lactobacillito decrease and coliforms to increase, resulting in an alteration of the gut microflora which may   →   diarrhea.
    • Antibiotic therapy: suppression of microflora (beneficial and non-beneficial).
    • Changes in diet: type or quality.
