A healthy digestive system is important for a horse’s condition, comfort and performance. However, modern routines can make it harder for the gut to work as nature intended.
Horses evolved to spend around 16 hours a day grazing, eating small amounts of fibre while moving. Longer periods stabled, reduced turnout, travel, exercise and changes to feed, forage or routine can all present additional digestive challenges.
Signs to look for:
Signs associated with digestive or gastric stress can vary between horses and may include:
• Reduced appetite or picky eating
• Weight loss or poor coat condition
• Reduced performance or lethargy
• Changes in behaviour or mood
• Sensitivity when girthing
• Bloating or digestive discomfort
• Loose or poorly formed droppings
These signs can have several possible causes, so any clinical change or concern should be discussed with a veterinary surgeon.
Supporting digestive health
Feeding and management should always come first. Owners can help by:
• Making forage the basis of the diet
• Avoiding long periods without fibre
• Feeding a high-fibre, low-starch ration
• Introducing dietary changes gradually
• Maximising turnout where practical
• Feeding a small fibre-based meal before exercise
As an absolute minimum, horses should receive forage equal to 1% of their bodyweight each day on a dry-matter basis, with a higher proportion being preferable for most animals.
