Thunderbrook Equestrian Hay Flakes. Thunderbrook Hay Flakes are a high-quality forage alternative, rich in natural fibre to promote healthy digestion and well-being. Designed especially for senior horses and those with dental challenges, these flakes soften quickly, making them easy to chew and digest. Unlike many soaked feeds, they require only 5 minutes in cold water no need for warm water or long waiting times! Horses are natural foragers, which means forage is the foundation of every horse s diet, playing a crucial role in maintaining digestive health, overall well-being, and natural behaviour. As natural grazing animals, horses are designed to consume small, fibre-rich feed throughout the day. Their unique digestive system depends on a steady intake of roughage to support gut motility, regulate stomach acid, and maintain a balanced microbiome in the hindgut. Composition 100% Meadow grasses and herbs (hot air-dried, pelletised). Analytical Constituents Crude Protein 8.0% Crude fat 3.1% Crude Fibre 29
