Feeding a senior horse is all about adapting to their changing needs. As horses age, they often develop dental problems, reduced digestive efficiency, and metabolic changes like insulin resistance or cushings disease. The key is to prioritize high-quality forage, use easily digestible feeds, and monitor body condition closely. Always involve your veterinarian in any dietary changes.
Adjust Forage for Easier Chewing and Digestion
The foundation of any senior horse diet is forage. However, older teeth may be worn, missing, or have sharp points that make chewing hay difficult. Provide soft, leafy hay like orchard grass or timothy. Avoid stemmy, mature hay. Soaking hay in warm water for 30 minutes can soften it further and reduce dust. Consider hay cubes or haylage (fermented hay) as alternatives. These are often easier to chew and digest. Ensure your horse has access to forage at all times, as constant grazing supports gut health and prevents ulcers.
Rethink Grains and Concentrates
Many senior horses have difficulty digesting large amounts of grain. Instead, look for senior-specific feeds that are pelleted or extruded to improve digestibility. These often include added fiber, prebiotics, probiotics, and yeast cultures to support hindgut fermentation. If your horse has metabolic issues like equine metabolic syndrome (EMS) or pituitary pars intermedia dysfunction (PPID), choose low-starch, low-sugar feeds. Be cautious with sweet feeds. You can also replace part of the grain with soaked beet pulp, which is high in fiber and low in sugar. Always feed by weight, not volume.
Balancing Vitamins and Minerals
Senior horses need specific nutrients to stay healthy. Quality senior feeds typically have balanced calcium, phosphorus, and trace minerals. However, if your horse is on a hay-only diet, you may need a ration balancer to supply missing vitamins and minerals. Pay special attention to vitamin E and selenium, which support immune function and muscle health. Many seniors also benefit from joint supplements containing glucosamine, chondroitin, or MSM. Discuss supplements with your vet, as over-supplementation can be harmful.
Feeding Schedule and Monitoring Body Condition
Divide daily feed into at least three meals to mimic natural grazing and prevent digestive upset. Offer fresh, clean water at all times. Monitor your horse’s body condition score (BCS) monthly. Seniors often lose weight in winter or lose muscle along the topline. If they are underweight, increase fat sources like vegetable oil or rice bran. If overweight, restrict calories but maintain forage to prevent boredom. Use a grazing muzzle if pasture is lush. Keep a diary of feed changes and weight.
Managing Common Health Issues
Dental care is crucial. Have your vet perform a dental exam at least annually, and more often if needed. Floating (filing) sharp points helps your horse chew properly. Watch for signs of choking like coughing, drooling, or panic during eating. Soaking feed can help. For horses with PPID, medication like pergolide is often prescribed, and diet must be low in non-structural carbohydrates. Work with your vet to adjust feed and medication. Avoid sudden diet changes; transition feeds over 7-10 days.
Key Takeaway
Prioritize soft forage, use senior-specific low-starch feeds, and monitor body condition closely with regular vet checkups.
