Alborada Well Foal Study

Exploring how foal gut bacterial communities in early life influence health and racing performance later in life.

Start date

January 2018

End date

February 2023

Overview

There is strong scientific evidence linking early colonisation of the neonatal gut with appropriate bacterial populations and the positive effects these have on the animal’s immune system.  However, early-life bacterial colonisation of the equine gut is poorly understood and associations with lifelong health have not been characterised. 

This project is designed to characterise two aspects of foal biology that are potentially key determinants of lifelong health: i) gut bacterial communities, and ii) the immune system. 

Hypothesis

Optimal development of gut bacterial communities in early life is associated with enhanced health and performance in later life. 

Aims and objectives

  1. Track the development of gut bacterial populations and immune system function in a cohort of 52 foals for the first year of life
  2. Explore potential associations between gut bacterial colonisation and immune development with key management events e.g. antibiotic use, diet, weaning method, contact with other horses
  3. Explore potential associations between gut bacterial populations, immune function and subsequent health, specifically susceptibility to respiratory disease, during the first three years of life
  4. Explore potential associations between early-life gut bacterial colonisation and summary measures of athletic performance e.g. official rating, career earnings.

This study was designed as a cohort study, tracking the health and performance of 52 foals bred for racing from birth until 3 years old. Through integration of detailed health, performance and gut microbiome data, we have been able to better understand the critical role played by early life gut bacterial communities in the lifelong health and performance of horses.
