Guide to Feeding Horses
Here are 10 top tips for feeding horses that support health, performance, and digestive wellbeing:
🐴 1. Feed Plenty of Forage
Forage (hay, haylage, or pasture) is the foundation of every horse’s diet and should make up at least 1.5–2% of their body weight per day in dry matter. That’s roughly 7.5–10 kg for a 500 kg horse. Fibre supports healthy digestion, maintains a stable gut microbiome, and satisfies a horse’s natural grazing behaviour, reducing boredom and stress-related habits like cribbing or weaving. Horse's on restricted grazing or who have restricted forage due to weight gain, obesity, laminitis concerns or injury, should be given a prebiotic supplement to support their hind gut.
🕰 2. Feed Little and Often
Horses are trickle feeders by nature, with stomachs that continuously produce acid and are relatively small. Feeding large meals can overwhelm the stomach and increase the risk of colic or gastric ulcers. Aim to divide concentrate feeds into two or three smaller meals per day if needed, and ideally provide free-access forage to mimic natural grazing patterns. Overweight horses (including horses with EMS, laminitis or metabolic disorders) may require their forage to be soaked to reduce calorie value and double netting can slow the intake, reducing the time spent not eating.
🧪 3. Balance the Diet
Even the best quality hay or grass may lack key nutrients like copper, zinc, or selenium. A daily vitamin and mineral balancer ensures your horse gets what they need without excess calories. This is especially important for horses on restricted diets, poor pasture, or who aren’t fed a complete compound feed.
💧 4. Provide Constant Access to Clean Water
Water is critical for every function in the horse’s body—from digestion to temperature regulation. Horses can drink between 25 and 55 litres per day, more if they are sweating heavily. Clean troughs and buckets daily, and in winter, check that water isn’t frozen. In summer, ensure water is cool and not contaminated by algae or insects.
📉 5. Avoid Sudden Changes in Feed
Any change in a horse’s diet—whether it’s new hay, grass, or hard feed—should be made slowly over 7–10 days. This allows the delicate population of gut microbes to adapt and reduces the risk of digestive upsets like diarrhoea, gas, or colic. Always introduce new feeds gradually and monitor your horse’s response.
🏃 6. Feed According to Workload, Age, and Condition
Feeding isn’t one-size-fits-all. Growing horses, seniors, broodmares, and those in heavy work all have different nutritional needs. Underfeeding can lead to poor performance, weight loss or developmental issues, while overfeeding can cause obesity, laminitis, or metabolic disease. Regularly assess your horse’s workload and condition and adjust accordingly.
⏱ 7. Keep a Consistent Feeding Routine
Horses are creatures of habit and thrive on routine. Feeding at irregular times can lead to stress and even digestive upset. Try to feed at the same times each day, and avoid long gaps without access to forage. Consistency helps regulate the horse’s internal body clock and digestive function.
🧂 8. Add Salt or Electrolytes Daily
Many horses don’t get enough salt, especially if they’re not fed hard feed or are sweating regularly. Plain white salt can be added to feed or provided via a salt lick, and horses in work may benefit from an electrolyte supplement to replace lost minerals. A basic rule is to add 1–2 tablespoons of salt per day, adjusting based on amounts provided in forage/hard feed, sweat loss and work levels.
🚫 9. Avoid Feeding Just Before or After Intense Work
Feeding a large meal immediately before or after hard exercise can compromise digestion and increase the risk of colic. It’s best to allow at least 1 hour before and after strenuous activity before feeding concentrates. Small amounts of forage can be given beforehand to protect the delicate stomach mucosa by creating a fibre raft, but avoid hard feeds until the horse has cooled down properly.
👀 10. Monitor Body Condition Regularly
Keep track of your horse’s Body Condition Score (BCS) every few weeks. This hands-on method helps detect weight gain or loss early so you can tweak the diet accordingly. Seasonal changes, pasture quality, and exercise levels can all impact condition. Use a weight tape for consistency and keep records to monitor trends over time.
