From Yard to Competition: The Gut Health Routine Behind Damien Griffin’s Horses

In Episode 8 of Precision Microbes’ What’s The Story series, veterinary consultant Tommy Heffernan meets with owner and rider Damien Griffin to explore how they’ve successfully integrated Precision Microbes’ liquid complementary feed into the stables’ daily routine. Over two years of consistent use, Damien and the team have observed marked improvements in digestive resilience, performance consistency, and recovery from common stressors such as travel and competition.

This in-depth article unpacks the science behind their success, offers real-world implementation tips, and outlines practical strategies that UK and Irish horse owners can apply to optimise equine gut health—key to improved welfare, reduced vet reliance, and enhanced performance.

Why Gut Health Matters for Horses

A healthy gut is central to equine wellbeing. Horses rely heavily on the hindgut, comprised of the caecum and colon, for fibre fermentation, volatile fatty acid synthesis, minimal digestion of forage, and optimal energy utilisation. But gut balance is fragile. Disruptions from stress, such as travel, competition, deworming, yard changes, medication, or irregular feeding, can upset the microbiome, leading to symptoms including colic, diarrhoea, reduced feed conversion, compromised immunity, and behavioural changes.

At Lissyegan, Damien explains that even minor digestive homeostatic shifts may present as dullness or soggy droppings—early indicators that gut equilibrium has been disturbed. Rather than waiting for visible symptoms, he shares how the Precision Microbes supplement has become integral to proactively protecting gut health throughout the year.

Two Years of Results: What Damien Has Seen

Over 24 months, Lissyegan Stables has implemented the supplement year-round, achieving several key outcomes:

• Zero major colic episodes: Despite competition and travel stress, there have been no significant colic incidences.

• Stable droppings: Even during feed or yard changes, manure quality has remained consistently good.

• Improved appetite and energy: Shorter recovery after competition or medication has been clearly noticeable.

• Reduced antibiotic dependency: Since adopting the supplement, antibiotic usage has dropped as minor digestive upsets resolved without intervention.

• Smoother travel and competition prep: Horses display less stress in behaviour and appetite when stabled overnight at events.

These findings echo broader sector research: gut-centred management can enhance digestive resilience, reduce vet loads, and deliver year-round welfare benefits for performance horses.

Precision Microbes Complementary Feed for Horse & Foal is a vet-developed, science-led liquid formula designed to support gut health and digestion. Its unique composition specifically targets hindgut health, promoting overall wellbeing in horses and foals. Highly palatable and easy to use, it is organically certified and safe for use in competition horses, making it a trusted choice for owners and professionals alike.

Crafting a Gut-Health Regime in Practice

Damien and Tommy outline a flexible, three-phase protocol that horse owners can adapt:

1. Daily Maintenance

• Add the recommended daily dose to feed or water.

• Supports microbiome balance during regular management routines.

• Ideal during turnout, rest periods, or low-stress phases.

2. Pre-Event Preparation

• Begin supplement 7–10 days before travel or competition.

• Increases microbiome resilience against stress.

• Continue daily use until full recovery post-event.

3. Acute Support

• At first signs of digestive disturbance—soggy droppings or reduced appetite—double the dose for several days.

• Aims to restore microbial function and calm inflammation swiftly.

Damien also emphasises routine: consistent feeding times, turnout schedules, and stable management are essential foundations for supplement effectiveness.

Stress Triggers: What Horses Face

From Damien’s experience, gut challenges often coincide with:

• Travel – even short trips can cause microbiome disruption.

• Competition yards – different stabling and feeding create stress.

• Feed changes – transitioning between forage, haylage, or early grass can destabilise digestion.

• Medication and vaccination events – antibiotics and NSAIDs may impact gut flora.

By aligning supplement timing with these stressors, owners can build resilience rather than respond reactively.

ROI: Why Gut Health is Worth the Investment

While not a traditional ROI case, the gut-health approach at Lissyegan suggests measurable savings and gains:

• Vet-care reduction – fewer medications and treatments for digestive issues.

• Performance consistency – less stress means fewer missed days and better energy reserves.

• Reduced veterinary risk – encouraging low antibiotic use aligns with regulatory targets and equine welfare expectations.

• Reputation-building – stables demonstrating proactive gut-care differentiate themselves in a competitive industry.

When considered holistically, the savings, in terms of vet bills, lost training days, and enhanced performance, support the investment in microbiome care.

UK & Ireland Application: Guidelines for Local Owners

Whether your horses live in paddock-rich environments or smaller yards, the Lissyegan model adapts well:

1. Select quality forage – minimise abrupt feed changes.

2. Implement Year-Round Supplementation – basic daily dosage during quiet periods.

3. Amplify During High Pressure – doubling up around travel, competition, or yard changes.

4. Equip Yards for Consistency – regular turnout, feeding, and water supply underpin gut health.

5. Monitor Key Indicators – track manure, body condition, behaviour, and appetite.

6. Avoid Sole Antibiotic Reliance – explore gut stabilisation protocols first with vet supervision.

Future Focus: Continuing the Journey

Damien plans to extend gut-health protocols to new recruits at Lissyegan, such as youngstock and broodmares. Gut resilience impacts fertility, foaling response, and growth rates—areas where longer-term supplementation may deliver further gains.

Tommy adds that this approach fits well with emerging UK and Irish equine industry trends: natural welfare-support strategies, reduced antibiotic policy, and evidence-led nutrition are becoming hallmarks of progressive yards.

Final Word

Lissyegan Stables’ two-year journey under Damien Griffin’s watch proves that gut health is not a luxury—it’s a necessity. Supporting the microbiome alongside stable management strategies can transform digestive resilience, reduce illness, and support performance, particularly for travel and competition horses. If you care deeply about your horse’s welfare and competitive edge, exploring a gut-health centred approach like that demonstrated by Precision Microbes could be your next step.
