A healthy diet is one of the most important foundations of horse care. Good nutrition supports everything from healthy digestion and strong hooves to maintaining a healthy weight, energy levels and overall wellbeing.
Every horse is different, and factors such as age, workload, breed and health conditions all influence their nutritional needs. Understanding the basics of equine nutrition will help ensure your horse receives a balanced diet throughout every stage of life.
Forage Comes First
Horses are grazing animals and are designed to eat little and often throughout the day. In the wild, they can spend up to 15 hours each day grazing, which helps keep their digestive system functioning properly.
For most horses, forage should make up the majority of their diet. This may include:
- Good quality grazing
- Hay
- Haylage (where appropriate)
Providing a constant supply of forage also helps reduce boredom and supports natural behaviours, contributing to better mental wellbeing.
Fresh Water Is Essential
Water is often overlooked, yet it is one of the most important nutrients a horse needs.
Horses should have access to clean, fresh drinking water at all times. Water requirements can increase significantly during warm weather, after exercise or when eating dry forage such as hay.
Regularly check water troughs and buckets to ensure they remain clean and free from contamination.
Feed According to Your Horse’s Needs
Not every horse requires hard feed or concentrates.
A horse’s diet should be based on their individual requirements, including:
- Age
- Breed
- Weight
- Body condition
- Workload
- Health conditions
For example, a retired pony living on good pasture may require very little additional feed, while a competition horse in regular work may need extra calories to maintain body condition.
If you’re unsure what is appropriate for your horse, speak to your vet or an equine nutritionist for guidance.
Make Changes Gradually
The horse’s digestive system is sensitive to sudden dietary changes.
Introducing new feeds too quickly can upset the balance of bacteria in the gut and increase the risk of digestive problems, including colic.
Whenever changing your horse’s diet, introduce new feeds gradually over 7 to 14 days, allowing their digestive system time to adapt.
Maintain a Healthy Weight
Both underweight and overweight horses are at risk of developing health problems.
An overweight horse may be more likely to suffer from:
- Laminitis
- Joint problems
- Reduced fitness
- Metabolic disorders
Meanwhile, horses that are underweight may lack energy, lose muscle condition and have a weakened immune system.
Regularly assessing your horse’s body condition and monitoring changes in weight can help identify problems before they become serious.
Treats in Moderation
Many owners enjoy rewarding their horses with treats, but these should only be offered occasionally and in moderation.
Too many treats can contribute to weight gain and encourage undesirable behaviours, such as mugging people for food.
If offering treats, always choose horse-safe options and avoid feeding foods that may be harmful to horses.
Good Nutrition Supports Lifelong Health
Providing the right diet is about more than simply filling a feed bucket. A balanced nutritional plan supports healthy digestion, helps prevent disease and enables horses to live active, comfortable lives.
By ensuring your horse has access to quality forage, clean water and a diet tailored to their individual needs, you’re giving them the best possible foundation for lifelong health and wellbeing.
If you’re ever unsure whether your horse is receiving the right nutrition, don’t hesitate to seek advice from your veterinary surgeon or an equine nutrition specialist.
