Feed the horse in front of you
An honest guide to what's in the bag. Tell us about your horse, add hay and pasture, and see which feeds and supplements fit, with every number traced to its source.
Your horse
This is an example horse. Change anything to make it yours.10–12% is the cutoff most often used for metabolic horses. Ask your vet what's right for yours.
Fine-tune hay, grass and feed
For most horses, hay and pasture supply far more sugar and starch than the bag does. Add what your horse eats in a day to see the whole picture.
Hay
A hay test is the only way to know its sugar.
Pasture
Grass sugar swings with season, weather and time of day.
Rough estimates: about 1.5 lb of grass per hour grazing, roughly halved by a muzzle.
Bagged feed
Choose one here, or tap “Use in ration” on any feed.
Find what fits Biscuit
Browse feeds and supplements in one place. Everything you choose goes into the plan, which checks it against your horse's conditions and the research.

Six things to talk over with your vet
How much hay and grass
Forage is usually most of a horse's diet. Many vets suggest around 1.5–2% of body weight a day. Ask your vet what's right for your horse.
Changing feeds
Sudden diet changes are linked to colic and laminitis. Ask your vet how gradually to switch your horse.
Weighing feed and hay
A scoop of one feed can weigh twice as much as another. Weighing your scoop and a flake once makes the estimates here more accurate.
Meal size
Large grain meals are linked to digestive upsets. Ask your vet how much to feed per meal and how many meals a day.
Water and salt
Horses often drink 5–15 gallons a day, more in hot weather. Ask your vet about salt and electrolytes for your horse.
Check-ups and teeth
Ask your vet how often your horse should have check-ups and dental care, especially as they get older.
Every ingredient on the tag, in plain English
What it is, why it's in the bag, which horses it suits, and how strong the research is.

Help us confirm the numbers
Brands don't always publish sugar and starch, and online listings often disagree. Owners holding the real bag tag are the best check we have.
Most needed
Feeds and supplements with numbers we couldn't confirm with the maker.
How it works
- Find the feed or supplement and open its details.
- Check the guaranteed analysis on your bag tag or label.
- Tap My tag matches, or enter the numbers your tag shows.
- We review submissions before changing any published number.

For research, not diagnosis
This site is not veterinary advice. It's an educational tool to help horse owners read feed labels and compare products. It does not diagnose, treat or prevent any condition, and it does not replace an exam or advice from your veterinarian. Always involve your vet before changing your horse's diet, and call them right away for any sign of laminitis, colic or illness.
How we pick the NSC number
NSC means non-structural carbohydrates: sugar plus starch. For each feed we use, in this order:
- The NSC the maker advertises, when they publish one.
- Starch + sugar from the guaranteed analysis, when both are on the label.
- A third-party estimate (lab test, retailer or blog), clearly marked as unconfirmed.
If none exist, we say "not published" instead of guessing.
What the badges mean
✓ Verified Numbers come from the maker's own website, spec sheet or label.
◐ Partly verified Some numbers come from the maker, others from retailers or third parties, or sources disagree. Unconfirmed numbers are underlined with a dashed line.
? Unconfirmed Only retailer, third-party or older sources were found.
Numbers were collected from manufacturer websites, retailer listings and the Mad Barn feed database in October 2026. Formulas change, and the tag on the bag in front of you is always the final word.
Neutrality
Rankings are based only on how a feed's published numbers match your horse. No brand can pay to change a ranking. Any future affiliate links or sponsored listings will be clearly labeled.
Known limits
- Fit checks are simple rules, not a full ration balance. The daily ration estimate covers sugar, starch and intake only, not minerals, protein or calories.
- Pasture intake and grass sugar are rough estimates. Grass can spike on sunny spring and fall afternoons and after frost.
- Ration balancers and fat supplements are fed in small amounts, so their NSC % matters less than a grain fed at 6 lb a day.
- Potassium (important for HYPP horses) and full ingredient lists aren't in the data yet.
- Ingredient write-ups and research ratings are drafts awaiting review by an equine nutritionist.
Horse feeding, explained simply
Short, plain-English guides to feed tags, sugar and starch, hay, and common health conditions, so you can have better conversations with your vet.
Terms of Use
Effective October 9, 2026
These terms apply to your use of Equine Feed Guide at equinefeedguide.com (“the site,” “we,” “us”). By using the site, you agree to them. If you don't agree, please don't use the site.
Not veterinary advice
Equine Feed Guide is for general education and research only. Nothing on the site is veterinary, medical or nutritional advice, and it does not diagnose, treat, cure or prevent any condition. Using the site does not create a veterinarian–client–patient relationship or any professional relationship with us. Always consult a licensed veterinarian or qualified equine nutritionist before changing your horse's diet, feed, supplements, grazing or care, especially for horses with laminitis, insulin resistance, PPID, PSSM, HYPP, ulcers, pregnancy or other medical conditions. If your horse shows signs of illness, colic or laminitis, contact a veterinarian immediately.
Information on the site
Product information, including guaranteed analyses, sugar and starch (NSC) values and supplement amounts, comes from manufacturer websites, product labels, retailer listings, third-party databases and user submissions. We label where each number came from and how confident we are in it, but we can't guarantee that any information is accurate, complete or current. Manufacturers change formulas, and online listings often disagree. The label on the product you buy is the final word.
Fit ratings, red flags, ration estimates and supplement suggestions are produced by general rules applied to the information you enter. They are rough estimates that may not suit your horse. Hay, pasture and individual horses vary widely.
Your responsibility
You are responsible for decisions you make about your horse's care. You agree to use the site's information only as a starting point for discussion with your veterinarian or nutritionist.
Your submissions
