Very interesting, yet not surprising! If the gut isn’t right, neither is the nervous system. It’s a domino effect leading to poor health and performance. Great work!
University of Surrey researchers recently found that a thoroughbred's gut bacteria composition at one-month-old may be a good indicator of its future performance.
Gut bacterial diversity at 28 days old was found to be predictive of future athletic performance, with higher bacterial diversity at one month positively associated with better racing performance.
Specifically, higher abundance of Anaeroplasmataceae bacteria was linked to higher official ratings, while increased levels of Bacillaceae at 28 days old were associated with better race placings.
Lower bacterial diversity at 28 days old was associated with increased health risks and foals with lower diversity had a significantly higher risk of developing respiratory disease later in life.
Interestingly, low diversity was also linked to increased risk of soft-tissue and orthopedic issues later in life.
The study also found that antibiotic use in the first month of life had long-term impacts:
- Foals treated with antibiotics in the first 28 days had significantly lower bacterial diversity at that age.
- These foals won significantly lower prize money in their racing careers.
- They also had a significantly higher rate of developing respiratory disease after 6 months of age.
The researchers believe these health impacts may be related to immunological priming in early life, though the exact reasons are not fully understood.
Work is currently underway to develop novel probiotics that will enhance the gut health of foals in early life and to investigate how antibiotics can be used whilst preserving gut health.
