Description

A happy tummy makes a happy horse! Thunderbrook Ulsa-X Prebiotic Mash is a gentle, nutritious, and warming mash designed to help horses maintain a healthy gut environment. This scientifically formulated blend combines multiple prebiotics to support the balance of beneficial gut microbes, naturally encouraging digestive well-being.

At the heart of this formulation is a patented fermented extract of Jerusalem Artichoke, scientifically shown to enhance gut flora diversity and support a healthy microbiome. This is complemented by oat bran, apple pomace, and psyllium husk, all known for their gut-friendly properties.

Ulsa-X Prebiotic Mash is also rich in natural fibres, omega-rich oils, and bioactive compounds sourced from premium Bavarian alpine grasses and herbs, esparsette, and toasted linseed crumble. These ingredients contribute to gut motility, digestive comfort, and nutrient absorption while maintaining a low sugar and starch content, making it suitable for horses with sensitive digestion or those prone to gastric stress.

For horses in need of extra condition, Ulsa-X Prebiotic Mash can also be fed in higher quantities as a digestible and nourishing meal, helping to support healthy weight gain.

This mash is particularly gentle on the stomach, making it a wonderful choice for:

  • Horses prone to competition stress – supporting digestive health during travel and performance.
  • Veteran and convalescing horses – easy to eat, highly digestible, and comforting.
  • Fussy eaters – a delicious warm mash to encourage appetite.

The carefully selected scientific formulation ensures that every ingredient serves a purpose—to support, maintain, and nourish the equine digestive system in a natural and effective way.
