Senior Horse Feeds: What to Look for on the Label

Walking down the feed aisle, you'll notice no shortage of bags labelled "senior" — but what actually makes a feed suitable for an older horse? And how do you know if the one you're buying is genuinely meeting your horse's changing needs?

The truth is, not all senior feeds are formulated equally. Some are excellent, purpose-built diets designed around the physiology of the ageing horse. Others are little more than a standard feed with a new label. The only way to tell the difference is to understand what's on the bag — and what it really means.

In this guide, we'll walk through every section of a senior feed label so you can make informed, confident choices for your older horse.

Why Senior Horses Have Different Nutritional Needs

Before we dive into the label, it helps to understand why older horses need something different in the first place.

As horses age — typically from around 15 to 20 years onward — several physiological changes occur:

• Dental deterioration makes chewing long-stem forage difficult or impossible.
• Digestive efficiency declines, meaning nutrients from feed aren't absorbed as readily.
• Muscle mass decreases (sarcopenia), increasing protein requirements.
• Immune function weakens, raising the need for antioxidants and key micronutrients.
• Metabolic conditions such as Cushing's disease (PPID) become more prevalent.

A well-formulated senior feed addresses all of these changes. A poorly formulated one may only address one or two — or none at all.

Understanding the Feed Label: Section by Section

Feed labels in the UK and EU follow a standardised format, but they can still be confusing. Here's how to read each section with your senior horse in mind.

The Product Name and Description

Start with the product description or marketing blurb. Look for clear statements about what the feed is designed to do. A good senior feed will typically mention one or more of the following:

• Support for older horses with dental issues
• Highly digestible fibre sources
• Added joint support
• Controlled starch and sugar levels

Be cautious of vague claims like "complete care" or "total nutrition" without specifics. These are marketing terms, not nutritional guarantees.

Analytical Constituents (The Guaranteed Analysis)

This is the most important section of the label. It tells you the actual nutrient levels in the feed. Here's what to look for:

#### Protein

Senior horses generally need higher protein levels than mature adult horses — typically 12–16% crude protein — to help maintain muscle mass. But crude protein alone doesn't tell the whole story. What really matters is the quality of the protein, specifically the amino acid profile.

Look for feeds that list lysine content or mention "quality protein sources" such as soya bean meal, alfalfa, or linseed. Lysine is the first limiting amino acid in the equine diet and is critical for muscle maintenance in older horses.

#### Fibre

Fibre is arguably the most important nutrient for any horse, and it becomes even more critical in seniors who can't chew hay properly. Look for a crude fibre content of at least 15%, ideally higher. Many of the best senior feeds function as partial forage replacers, with fibre levels of 18–25%.

The type of fibre matters too — check the ingredients list for super-fibres like beet pulp, soya hulls, and alfalfa, which are far more digestible than straw or oat husks.

#### Oil (Crude Fat)

Oil is an excellent calorie source for older horses because it's energy-dense and doesn't spike blood sugar. A good senior feed will contain 5–10% oil. Higher oil levels (above 6%) are particularly useful for seniors who struggle to maintain weight.

Look for named oil sources like linseed oil, soya oil, or rapeseed oil. These provide beneficial omega-3 and omega-6 fatty acids that support coat condition, joint health, and immune function.

#### Starch and Sugar

This is a critical area for senior horses, especially those with PPID (Cushing's disease), insulin dysregulation, or a history of laminitis. Look for feeds where combined starch and sugar is below 15% — and ideally below 12% for metabolically sensitive horses.

Not all labels list starch and sugar separately. If only "non-structural carbohydrates" or "NSC" is listed, the same guideline applies. If neither is listed, contact the manufacturer directly — a reputable company will always share this information.

#### Ash

Ash content represents the mineral content of the feed. Values between 7–10% are typical and indicate a reasonable mineral inclusion. Extremely high ash values (above 12%) can sometimes indicate the use of lower-quality ingredients or excessive filler.

The Ingredients List

Ingredients are listed in descending order by weight. This tells you what the feed is predominantly made of. For a senior feed, you want to see digestible fibre sources near the top of the list:

• Beet pulp (sugar beet pulp) — highly digestible, excellent fibre source
• Alfalfa (lucerne) — quality protein and calcium
• Soya hulls — digestible fibre with minimal starch
• Linseed (flax) — omega-3 fatty acids and oil
• Oat feed / oat hulls — moderate fibre source

Be wary if the first ingredients are cereal grains (wheat, barley, maize/corn) or unnamed "cereals" and "cereal by-products." These are starch-heavy and not ideal as the foundation of a senior diet, especially for metabolically compromised horses.

Vitamins and Minerals

As digestive efficiency declines, older horses become less effective at absorbing vitamins and minerals from their diet. A quality senior feed should contain elevated levels of key micronutrients:

• Vitamin E — An antioxidant critical for immune and muscle function. Look for at least 200–300 IU/kg, ideally higher.
• Vitamin C — Horses can synthesise their own vitamin C, but this ability declines with age. Added vitamin C is a bonus in a senior feed.
• B vitamins — Especially important if hindgut function is compromised, as B vitamins are normally produced by gut microbes.
• Selenium — Works alongside vitamin E as an antioxidant. Levels should be carefully balanced (not excessive).
• Zinc and copper — Essential for hoof quality, immune function, and coat health. Look for chelated or organic forms (e.g., zinc chelate, copper chelate) as these are better absorbed.
• Phosphorus and calcium — Important for bone maintenance. The calcium-to-phosphorus ratio should ideally be between 1.5:1 and 2:1.

Additives and Supplements

Many senior feeds include functional additives. These aren't essential, but they can add genuine value:

• Prebiotics (FOS, MOS, or yeast) — Support hindgut health and improve fibre digestion. Particularly valuable for older horses.
• Glucosamine and chondroitin — Joint support ingredients. Check the inclusion rate — some feeds include only token amounts.
• Antioxidants (vitamin E, selenium, vitamin C) — Already covered above, but worth noting if they're listed as specific additives at therapeutic levels.
• Biotin — Supports hoof quality, useful for seniors with crumbly or poor-quality hooves.

Always check whether these are included at meaningful levels. A feed that lists glucosamine but only at 500 mg per daily serving is unlikely to make a clinical difference — research suggests at least 5,000–10,000 mg per day may be needed for joint support.

Feeding Rate: The Hidden Factor

Here's something many horse owners overlook: the guaranteed analysis only means something in the context of the recommended feeding rate.

A feed might appear to have excellent vitamin and mineral levels per kilogram, but if the recommended daily amount is only 500g, your horse might not actually receive adequate micronutrition. Conversely, feeding a high-calorie senior feed at the full recommended rate to a good doer could lead to weight gain.

Always check:

• What is the recommended daily feeding rate for your horse's weight and workload?
• At that rate, does the feed deliver sufficient vitamins, minerals, and protein?
• Can the feed be fed as a partial or complete forage replacer if your horse has dental issues?

Some senior feeds are designed to be fed at high rates (3–5 kg per day) and can replace a significant portion of the forage ration. Others are concentrate feeds designed to be fed at 2–3 kg alongside good-quality hay or haylage.

Red Flags to Watch For

When evaluating a senior feed label, watch out for these warning signs:

• "Cereals" listed as the first ingredient without further specification — you don't know what you're feeding.
• No starch or sugar declaration — the manufacturer may be hiding high NSC levels.
• Very low recommended feeding rates with high calorie density — this often means insufficient fibre and micronutrients unless supplemented separately.
• Excessive molasses — a small amount is fine for palatability, but it shouldn't be a primary ingredient.
• No mention of chelated or organic minerals — inorganic minerals are cheaper but less bioavailable, especially for older horses with compromised digestion.

Putting It All Together: Choosing the Right Feed

Selecting the best senior feed isn't just about picking the bag with the best label — it's about matching the feed to your individual horse's needs. Consider:

1. Can your horse chew hay? If not, you need a high-fibre senior feed that can serve as a forage replacer.
2. Is your horse a good doer or a poor doer? This determines whether you need a low-calorie or high-calorie formulation.
3. Does your horse have PPID or metabolic issues? If so, low starch and sugar is non-negotiable.
4. What else is in the diet? The feed label only tells you about one component. You need to look at the total diet — forage, feed, supplements, and any additional bucket feeds.

This is where analysing your horse's overall diet becomes invaluable. A feed that looks perfect on the label might still leave gaps — or create excesses — when combined with your horse's forage and other supplements. Taking a whole-diet approach ensures nothing is missed.

A Quick Label-Reading Checklist for Senior Feeds

Use this checklist next time you're comparing senior feeds:

• [ ] Protein: 12–16%, with quality sources (soya, alfalfa, linseed)
• [ ] Fibre: 15%+ crude fibre, with digestible sources (beet pulp, soya hulls)
• [ ] Oil: 5–10% for calorie density and coat/joint support
• [ ] Starch + sugar: Below 15% (below 12% for metabolically sensitive horses)
• [ ] Vitamins and minerals: Elevated levels, chelated mineral forms preferred
• [ ] Prebiotics or yeast: Present for digestive support
• [ ] Feeding rate: Realistic for your horse's needs and delivers adequate nutrition
• [ ] Ingredients list: Fibre sources listed before cereal grains
• [ ] Joint support ingredients: At meaningful inclusion levels (if relevant)

Final Thoughts

Reading a feed label might not be the most glamorous part of horse ownership, but for senior horses, it can make a genuine difference to quality of life. A well-chosen senior feed supports digestion, maintains muscle and body condition, protects joints, and helps manage the metabolic challenges that come with age.

Don't rely on the front of the bag — flip it over, read the fine print, and ask questions. Your older horse deserves a diet built on evidence, not marketing. And when in doubt, work with a qualified equine nutritionist or use a diet analysis tool to make sure every piece of the puzzle fits together.

Your senior horse has given you years of partnership. The least we can do is give them the nutrition they need to enjoy their golden years comfortably.
