Teff Hay for Horses: A Low-Sugar Guide

Teff grass hay is a low-sugar forage, the lowest-sugar product we stock. It fits easy keepers and horses managing metabolic conditions, insulin resistance, or laminitis. We keep lab results on file for the current lot so you can see the numbers before you buy, and any forage change should be gradual and run past your vet.

If you manage a horse with metabolic issues, insulin resistance, or a history of laminitis, forage selection carries real stakes. The wrong hay, or the right hay introduced too quickly, can matter as much as any other management choice. This guide covers teff hay for horses: what it is, why its low-sugar profile matters, which horses are the right candidates, and what our lab results show. We stock teff grass at our Williston, FL location and keep nutritional test results on file for the current lot, so everything here is grounded in actual bales, not generic charts. Before any diet change, run it by your vet and ask us for the current lot's forage analysis.

What Is Teff Grass Hay?

Teff is a warm-season grass, and teff grass hay occupies its own category at the feed store. That distinction matters when you are comparing options and trying to understand what you are actually feeding. It is not a timothy, not an orchard grass, and not a legume like alfalfa or peanut hay. It is its own forage with its own profile.

One quality marker worth checking before you buy is the interior color of a bale. When you crack a good bale open, the inside should be green. Fading or browning on the inside can point to heat during curing or moisture in storage. Like any new forage, teff should come in gradually rather than all at once, which is covered in the colic section below.

Understanding Teff Hay's Low-Sugar Profile

The nutritional reason teff hay draws attention from owners of metabolic horses is its carbohydrate content. Teff is a low-sugar forage, and it is the lowest-sugar product we currently stock. That positioning matters if your vet has given you a specific NSC ceiling to stay under when selecting hay.

NSC stands for non-structural carbohydrates. For horses at risk from laminitis or insulin dysregulation, the most important subset is ESC plus starch. ESC is the ethanol-soluble carbohydrate fraction, which includes simple sugars. Add starch to that value and you have the portion of a hay most likely to drive an insulin response in a susceptible horse.

When you read a forage analysis, here are the numbers to focus on:

• ESC plus starch: This combined value is what your vet compares against any NSC target set for your horse's management plan.
• ADF and NDF: Acid detergent fiber and neutral detergent fiber speak to digestibility and gut fill, which tells you how much volume and fiber the hay contributes.
• RFV: Relative feed value puts the hay's overall nutritional quality into context against a reference standard.

Category labels are a useful filter. The lab sheet is the actual answer. That is why we make test results available for the current lot before you load a pallet.

Which Horses Are a Good Fit for Teff Hay

Teff grass is suitable for horses that need a low-sugar diet. In concrete terms, it covers several situations Florida horse owners run into regularly:

• Easy keepers. These horses gain weight on modest feed and often do better with a lower-calorie, lower-sugar forage as their hay base rather than richer options.
• Horses with insulin resistance. Keeping dietary ESC plus starch within a vet-established range is central to managing insulin dysregulation, and low-sugar forage is a foundation of that plan.
• Laminitis-prone horses. A laminitis history puts forage sugar content under ongoing scrutiny. Teff is a reasonable forage to discuss with your vet once you have a current lot analysis in hand.
• Horses with PPID (Cushing's disease). PPID management typically includes a low-NSC diet as part of a broader veterinary plan, and teff may fit within that framework.
• Horses on any vet-directed low-NSC plan. Whatever the underlying reason, if the instruction is to keep forage sugar low, teff hay is one of the first options worth asking about.

Whether teff is right for your barn means matching the forage profile to your horse's actual clinical picture. Metabolic horses tend to be managed with close veterinary oversight anyway, so your vet should weigh in before you make any switch.

Pro tip: Do not change your horse's forage based on a category label alone. Ask us for the nutritional analysis on the current teff lot, share it with your vet, and let the actual ESC plus starch number guide the decision. That step applies to teff or any other hay we stock.

Does Teff Hay Cause Colic?

This comes up in enough barn conversations that it deserves a direct answer. Nothing specific to teff raises colic risk above that of any other new hay. The risk that does exist is the one that comes with any forage change: transition speed.

The equine hindgut depends on a stable microbial population. Rapid forage changes disrupt that population, and the disruption period is when digestive upset is most likely. Switching from bermuda to teff, from alfalfa to teff, or from one cutting of the same hay to another all carry the same transition risk if the change happens too fast.

A slow transition reduces that risk. A reasonable approach:

1. Replace about 25 percent of your horse's current hay with teff for the first few days.
2. Move to roughly 50 percent over the following three to five days.
3. Continue stepping up gradually over two to three weeks until fully transitioned.

For a horse with a documented colic history, involve your vet before any forage change. A horse with prior digestive issues warrants extra care whenever the forage source changes.

What Our Lab Results Show

We keep nutritional test results on file for our teff grass. That means you can look at actual numbers for the current lot before you commit to a purchase, rather than relying on a generic estimate from a nutrition database. The values that matter most for a horse on a low-sugar management plan are:

• ESC plus starch: Add these two figures to get the number your vet is likely measuring against any target threshold.
• NSC: Total non-structural carbohydrates, which gives broader context for the hay's overall carbohydrate load.
• ADF and NDF: Fiber fractions that reflect digestibility and how well the hay will keep your horse satisfied between feedings.
• RFV: The comparative nutritional quality rating for this specific lot.

Results vary by cutting and lot, which is exactly why having the test sheet for the bales you are buying matters more than any published range. If you are in Marion, Levy, or Alachua County and want to see the bales or talk through whether teff fits your horse's situation, give us a call or stop by the Williston yard. Ask for the current lot's nutritional analysis before you buy.

Frequently Asked Questions

What is teff hay and how is it different from other forages? Teff is a warm-season grass that produces a notably low-sugar bale. What sets it apart from most common forages is its carbohydrate profile. Where many grasses carry higher non-structural carbohydrate levels, teff comes in at the low end. If you open a bale, the interior should be green, which is a good sign of curing quality. For horses that need to stay on a low-sugar diet, that combination of color and chemistry makes teff worth a close look.

Which horses are good candidates for teff hay? Teff is a practical choice for horses that need to limit sugar intake. That includes easy keepers, horses managing metabolic conditions, and any horse whose veterinarian or nutritionist has recommended a low-NSC diet. Because teff is the lowest-sugar forage we carry, it gives owners a roughage option that keeps horses eating long-stem forage without a heavy carbohydrate load. Always work with your vet before switching based on a metabolic concern.

How does teff compare to the other low-sugar forages you carry? Among the forages we stock and test, teff grass is the lowest-sugar option we offer. Other grasses and legumes we carry vary in NSC depending on cutting, curing conditions, and the time of year the hay was put up. If you are comparing options for a horse on a restricted-sugar diet, our lab results for the current teff lot give you a concrete number to bring to your vet or nutritionist rather than a general estimate.

Do you have actual lab results for the teff hay, or just general claims? We keep nutritional test results on file for our teff grass. We test forage batches so you are not working from generic published averages, which can vary widely by region, cutting, and season. Ask us for the current lot results when you call or stop in. Having those numbers on hand lets your vet or an equine nutritionist give you a real recommendation rather than a guess.

How can I tell if a teff bale is good quality when it arrives? One reliable visual cue is the color inside the bale. Teff that has been properly cured and stored should show green on the interior when you open it. Fading or browning inside can indicate heat damage during curing or moisture issues in storage. Beyond appearance, the lab results we keep on file for each lot give you the nutritional picture that a visual check alone cannot provide.

Is teff hay a good fit for horses prone to laminitis? Teff is a low-sugar forage, and limiting sugar intake is often part of a veterinary management plan for laminitis-prone horses. Because teff is the lowest-sugar product we carry, it is a reasonable forage to discuss with your vet if your horse has a history of laminitis or insulin dysregulation. We can share the current batch test results so your vet has the actual ESC and starch numbers rather than a category label. Forage choice supports a veterinary plan, it does not replace one.
