Phileo Equine - UK & Ireland Our products harness the power of microbes to support digestive & immune function in horses & ponies. The Equine Microbiome - More than just gut health!

As the engine room, the hindgut microbiome is irreversibly linked to the overall health and welfare of all equines. To ensure optimum health and performance, we must support the microbial community within the hindgut. At Phileo by Lesaffre, we harness the power of microbes to support this engine room, which in turn supports digestive function, immunity, performance, fertility and welfare in all ag

es and performance levels of equines. No added chemicals, no magic powder, no unsubstantiated claims. Just microbiology at its best. Phileo by Lesaffre is the pioneering animal nutrition division of Lesaffre, a global leader in yeast and fermentation. We create baker’s yeast based feed additives that improve the gut health and performance of wide range of animals, including farm animals, pets and – of course – horses and ponies. Our expertise is built on a foundation of nearly 170 years of research and manufacturing, enabling us to get the best out of the microbiological world for the benefit of your horse. On the cutting edge of innovation, Phileo by Lesaffre has R&D divisions in Europe, North America and Asia, and our veterinarians and animal nutritionists work closely with our wider research teams.

Travelling, changes in routine and more intensive training all place extra demands on the hindgut microbiome. When this delicate microbial balance is disrupted, it can affect digestive function, nutrient utilisation and overall resilience – all essential for a successful competition season!

As our understanding of the equine microbiome grows, supporting gut stability is becoming an increasingly important part of performance nutrition.

We outline some of the science behind feeding sport horses for a more stable microbiome and why it matters for performance here: https://phileoequine.com/our-blog/feeding-sport-horses-for-a-more-stable-microbiome

The equine hindgut is more than a site of digestion. It's a complex ecosystem where microbial balance, gut integrity and immune function all influence health and performance.

And by combining strategies can deliver broader support to horses and ponies.

Actisaf® Sc 47 live yeast probiotic supports stabilisation of the hindgut microbiome and in turn key fibrolytic bacteria, while Safmannan® premium yeast postbiotic supports the maintenance of gut integrity and function through its bioactive yeast components.

Together, they offer a complementary approach to supporting digestive health, making them valuable tools for feed formulators, nutritionists and veterinary professionals looking to optimise equine nutrition.

☀️ Does your horse have enough access to shade?

Research has shown that horses standing in direct sunlight experience significantly greater heat loads than those with access to shade, even when the air temperature is the same.

Natural tree cover, field shelters or well-ventilated stables during the hottest part of the day can all help reduce the risk of heat stress.

Small management changes can make a big difference during periods of hot weather – read our latest article to learn more:

When we think about heat stress, we often focus on cooling the horse from the outside.

But what about supporting them from the inside?

Emerging research suggests periods of environmental stress may influence the balance of the hindgut microbiome. Maintaining a healthy and stable hindgut environment may help support digestive function when horses are exposed to increased thermal demands.

Alongside practical management such as shade, fresh water, ventilation and appropriate cooling after exercise, nutrition may also have a role to play in supporting horses during warmer weather.

🌡️ Did you know that horses are the only mammal, other than humans, that cool themselves primarily through sweating?

But when humidity is high, sweat evaporates more slowly, making it harder for them to cool off even as they continue to sweat and lose fluids.

Heat stress isn't always obvious. As prey animals, horses are naturally good at masking discomfort, so the earliest signs can be easy to miss.

Keep an eye out for:
🐴 Increased breathing rate
❤️ Elevated heart rate
💦 Excessive sweating – or surprisingly little sweating
💧 Mild dehydration
🍽️ Changes in appetite, behaviour or willingness to work

Research into the foal’s developing microbiome – and its impact on future health and performance – is reinforcing just how important the first few weeks of life really are…

But what can we actually do with this information?

Simple management practices that can help support healthy microbial development include:
✔️ Ensuring good colostrum intake
✔️ Providing fibre-rich diets for mares
✔️ Minimising unnecessary stress
✔️ Avoiding sudden dietary or environmental changes
✔️ Supporting turnout and social interaction
✔️ Using antibiotics carefully and only when necessary

As our understanding of the equine microbiome grows, these early-life foundations are becoming increasingly important.

A foal’s first few weeks of life could influence far more than we once thought.

A landmark study led by Professor Chris Proudman at the University of Surrey followed Thoroughbred foals from birth to three years old, exploring how the developing gut microbiome related to future health and racing performance.

One of the most striking findings? Foals with greater microbial diversity at around 28 days old went on to show better health outcomes and stronger racing performance later in life.

It’s a fascinating insight into how early-life management may help shape future potential…

What happens in a foal’s gut during the first month of life could have long-term consequences.

At around 28 days old, foals go through a major transition:
✔️ More exposure to pasture and environmental microbes
✔️ Declining maternal antibodies from colostrum
✔️ A still-developing immune system

Researchers now believe this may represent a “critical window” where the microbiome helps shape future health, resilience and performance.

It’s a fascinating area of research that could change how we support mares and foals in early life.

Could the first few weeks of a foal’s life shape their future health and performance?

Emerging research suggests the developing gut microbiome may influence far more than digestion alone – including immune development, stress resilience, behaviour and even future athletic potential.

One major study found foals with greater microbial diversity at around 28 days old had better health outcomes and stronger racing performance later in life.

It’s changing how we think about early-life management, nutrition and the importance of supporting hindgut stability from day one.
