What to Feed a 30-Year-Old Horse: A Comprehensive Guide

Proper nutrition is essential to maintain the health and well-being of all horses, but it becomes even more critical as they age. As horses enter their senior years, their nutritional needs change, and it’s essential to adapt their feeding routines to accommodate these changes.

This guide will provide detailed information on what to feed a 30-year-old horse, focusing on their unique dietary requirements and how to ensure they maintain a healthy weight and condition.

What to Feed a 30-Year-Old Horse?

To feed a 30-year-old horse, provide high-quality forage, such as soft, leafy hay, and consider a specially formulated senior feed with lower non-structural carbohydrates. You may also add beet pulp, rice bran, or low-starch grains for additional calories. For horses with dental issues, complete pelleted rations soaked in water can be beneficial.

Understanding the Nutritional Needs of a 30-Year-Old Horse

What to Feed a 30-Year-Old Horse

As horses age, their digestive systems become less efficient, and they may experience dental issues that make it difficult for them to consume and process traditional feedstuffs. Consequently, their nutritional needs change, and it’s crucial to adjust their diet accordingly.

Forage should always be the foundation of any horse’s diet, regardless of age. It’s essential to provide a consistent supply of good-quality forage to meet the horse’s energy and fiber needs.

For a 30-year-old horse, this means focusing on high-quality grass hay and corn, which are both easy to digest and provide the necessary nutrients to maintain their condition.

Feed Choices for Older Horses

When selecting feed for a 30-year-old horse, it’s essential to consider their unique nutritional requirements and any health issues they may be experiencing. The following feed choices are suitable for most senior horses:

Good quality grass hay: Grass hay is an excellent source of fiber and provides the necessary energy to maintain the horse’s weight and condition. Opt for soft, leafy hay with minimal dust and mold to ensure it’s easily digestible for your senior horse [3].

Corn: Corn is a high-energy feed that can help meet the energy demands of older horses, particularly those struggling to maintain their weight. It’s essential to feed corn in moderation to avoid digestive upset.

High-quality forage: Providing high-quality forage is the foundation of any horse’s diet, especially for senior horses. Opt for soft, leafy hay that is easy to chew and digest. Alfalfa hay can be an excellent choice due to its higher protein, calcium, and energy content.

However, it’s essential to balance alfalfa with grass hay to prevent an overabundance of certain nutrients.

Complete pelleted rations: For horses with dental issues or difficulty chewing and digesting hay, a complete pelleted ration can be a suitable alternative. These rations contain all the necessary nutrients, including fiber, in an easily digestible form.

Soak the pellets to create a soft, mash-like consistency that is more comfortable for horses with dental problems to consume.

Senior feeds: Many feed companies produce specially formulated feeds for older horses. These feeds typically have higher fiber content, making them easier to digest. They also contain essential vitamins, minerals, and amino acids to support the unique nutritional needs of senior horses.

Look for a senior feed with a lower non-structural carbohydrate (NSC) content to reduce the risk of metabolic issues.

Beet pulp: Beet pulp is a highly digestible source of fiber that can provide additional calories to senior horses struggling to maintain their weight. It can be soaked and added to the horse’s regular feed, or fed as a separate meal.

Be sure to choose a beet pulp product without added molasses, as the extra sugar can be detrimental to horses with metabolic issues.

Rice bran: Rice bran is a high-fat, high-fiber feedstuff that can be a valuable addition to a senior horse’s diet. It provides easily digestible calories, making it suitable for weight maintenance or gain. Opt for stabilized rice bran products to ensure proper nutrient balance and longer shelf life.

Low-starch grains and concentrates: For senior horses requiring additional calories beyond forage and senior feeds, low-starch grains and concentrates can be beneficial. Look for feeds with a lower NSC content, such as oats or barley, to reduce the risk of metabolic issues.

Oil: Adding vegetable oil, such as corn, soybean, or flaxseed oil, to your senior horse’s diet can provide additional calories without increasing the risk of digestive upset. Oil is a highly concentrated source of energy and can be easily mixed into the horse’s regular feed.

It’s crucial to avoid certain feeds for senior horses, such as legumes (alfalfa and clover), wheat bran, and beet pulp, as they can be high in calcium or phosphorus, which can exacerbate existing health issues.

Amount and Frequency of Feeding

As a general rule, horses should consume 1.5-2.5% of their body weight daily in forage. For easy keepers, aim for the lower end of the range, while those struggling to maintain weight may require more. It’s essential to monitor your horse’s condition and adjust their feeding amounts accordingly.

Older horses often benefit from having their feed split into multiple smaller meals throughout the day. This approach allows for more efficient digestion and absorption of nutrients, reducing the risk of digestive upset.

Monitoring Starch Content in the Diet

Starch is an essential component of a horse’s diet, providing energy for their daily activities. However, it’s crucial to monitor and limit starch intake in older horses, as excessive consumption can lead to digestive issues and exacerbate existing health problems.

As a guideline, limit starch content to less than 1 gram of starch per kg body weight per feeding. For example, a 450-kg (1,000-pound) horse should receive no more than 5 pounds of grain or concentrate per feeding.

Supplements for Senior Horses

In addition to adjusting their primary feed, it may be necessary to provide supplements to ensure a 30-year-old horse receives all the nutrients they need. Common supplements for senior horses include:

Joint supplements: Aging horses often experience joint stiffness and discomfort. Supplements containing glucosamine, chondroitin sulfate, and MSM can help support joint health and improve mobility.

Probiotics and prebiotics: These supplements can help support the horse’s digestive system by promoting a healthy balance of gut bacteria and improving nutrient absorption.

Vitamins and minerals: As horses age, their ability to absorb essential vitamins and minerals may decline. Providing a well-balanced vitamin and mineral supplement can help ensure they receive all the necessary nutrients.

Omega-3 fatty acids: These essential fatty acids can help support overall health, reduce inflammation, and improve coat condition in senior horses.

Weight gain supplements: Older horses struggling to maintain their weight may benefit from a weight gain supplement, which provides additional calories and nutrients in an easily digestible form.

Remember to consult with your veterinarian before adding any supplements to your horse’s diet.

Making Dietary Changes Gradually

When transitioning a horse to a new diet or feed, it’s crucial to make changes gradually to avoid digestive upset. A slow transition allows the horse’s digestive system to adjust to the new feed, reducing the risk of colic or other complications.

A suggested schedule for introducing the new feed is as follows:

  • Day 1: 75% old feed and 25% new feed
  • Day 3: 50% old feed and 50% new feed
  • Day 5: 25% old feed and 75% new feed
  • Day 7: 100% new diet

Monitoring Your Horse’s Condition

It’s essential to regularly monitor your senior horse’s condition and adjust their diet as needed. Keep an eye on their weight, body condition score, coat condition, and energy levels. If you notice any significant changes or concerns, consult with your veterinarian to discuss potential adjustments to their feeding routine.


In conclusion, feeding a 30-year-old horse requires an understanding of their unique nutritional needs and careful selection of appropriate feedstuffs. By providing high-quality forage, avoiding specific feeds that may exacerbate health issues, and considering the use of supplements, you can help your senior horse maintain a healthy weight and condition well into their golden years.

Always consult with your veterinarian for personalized advice and support in managing your horse’s nutritional needs.
