Why We Test Our Hay: What a Forage Analysis Really Tells You

Hay testing is a nutritional analysis that benchmarks the quality of a forage so you can feed with confidence. At Farmers Direct we test every field we grow, sampling bales from across the whole stack to build an accurate average, because a single sample is only a snapshot in time. A hay test does not guarantee what is in every bale, but it is an excellent benchmark for evaluating quality and making better feeding decisions.

If you have ever wondered what is actually in the hay you feed, you are asking the right question. At Farmers Direct Hay and Feed our goal is to give you the highest quality hay possible, and that is exactly why we invest in a nutritional analysis on every field we grow. Hay testing takes the guesswork out of feeding. This guide explains what a hay test is, how we sample our forage, and what a forage analysis can and cannot tell you, straight from the farm that grows it.

What a Hay Test Actually Is

A hay test, also called a forage analysis, is a laboratory measurement of a forage's nutritional content. Instead of guessing at protein or sugar levels by look and smell alone, you get real numbers you can feed against. We are proud to be one of only two feed stores in Florida that actually grow the hay we sell, so testing our own fields is a natural part of how we do business. Every lot we grow ships with a Fast Track 600 lab panel on file, which reports the values that matter most for horses: protein, sugars, starch, and fiber.

Growing the hay ourselves means there is no middleman between the field and your barn, and no guessing about where a load came from or how it was handled. The lab analysis is simply the paperwork that backs up what we already know about our forage.

A Hay Test Is a Snapshot in Time

Here is the most important thing to understand about any forage analysis: it is a snapshot in time. Think of it this way. If I went on a week-long vacation and came back with only one picture, that single photo would not tell the whole story. It would just show where I was at one particular moment.

Hay testing works much the same way. One sample from one bale is a single photo. It might be accurate for that exact bale at that exact moment, but it does not describe the whole field. That is why the way a hay is sampled matters just as much as the test itself.

How We Sample: Random Bales Across the Whole Stack

Rather than pulling one sample from one bale, we randomly sample bales from throughout the entire stack. Those individual core samples are then combined into one composite, which the lab analyzes to create an average for that field.

The result is a much more accurate picture of the hay's overall nutritional value than any single bale could give. In short:

• We core-sample many bales, not one. Random selection across the stack captures the natural variation in a field.
• The samples are combined into one composite. The lab reads the average, not an outlier.
• The analysis is tied to the field. Each field we grow gets its own benchmark.

This is standard best practice for forage testing, and it is how we make sure the numbers on the report reflect the hay you will actually load in your truck.

A Benchmark, Not a Guarantee

We want to be honest about what a hay analysis is and is not. No forage analysis is a guarantee of what every single bale contains, because hay is a natural product and some variation is normal. What a good test gives you is an excellent benchmark. It helps us evaluate forage quality, estimate nutritional value, and, most importantly, gives you the information to make better feeding decisions.

Treat the analysis the way your veterinarian or nutritionist would: as a reliable reference point for a field, not a promise stamped on each individual bale.

How to Read a Forage Analysis

When you look at a hay report, a few values do most of the work. Here is what they mean in plain language:

• Crude protein. The protein content of the forage, which matters most for growing, working, and breeding horses.
• ESC plus starch. The sugar and starch fraction. This is the number your vet compares against any NSC ceiling for a horse managing insulin resistance, laminitis, or another metabolic condition.
• ADF and NDF. Acid and neutral detergent fiber, which speak to digestibility and how much fiber and gut fill the hay provides.
• RFV. Relative feed value, a single figure that puts the hay's overall quality in context against a reference standard.

If you have a specific target from your vet, such as a low-sugar forage for a metabolic horse, these are the numbers to match the hay to. Our low-sugar teff grass is a good example of a forage where the lab numbers do the talking, and our guide to feeding metabolic horses walks through how to use them.

Feeding With Confidence

Whether you are feeding performance horses, breeding mares, growing foals, or simply trying to keep your horses healthy, having a nutritional analysis takes the guesswork out of feeding. You are no longer choosing hay by color and smell and hoping for the best. You are matching a real forage profile to what your horse actually needs.

It is just one more way we are committed to providing quality hay and helping our customers feed with confidence. When you are deciding how to choose hay for your horse or comparing our forage options, ask us for the current lot's analysis. We keep the lab results on file so you can see the numbers before you buy, and we are always glad to talk through them with you. Reach out about hay delivery across North Central Florida, and feed your next load with confidence.

Frequently Asked Questions

What is a hay test?

A hay test, or forage analysis, is a laboratory measurement of a forage's nutritional content, including protein, sugars, starch, and fiber. It gives you real numbers to feed against instead of guessing at quality by look and smell.

How do you sample hay for testing?

We randomly core-sample bales from throughout the entire stack, then combine those samples into one composite that the lab analyzes. Sampling across many bales builds an accurate average for the field, since one sample from one bale is only a snapshot in time.

Does a hay test guarantee what is in every bale?

No. Because hay is a natural product with some normal variation, no analysis guarantees the content of every single bale. A test is an excellent benchmark for a field's overall quality and nutritional value, not a promise stamped on each bale.

What does a forage analysis measure?

The most useful values are crude protein, ESC plus starch (the sugar and starch fraction that matters for metabolic horses), ADF and NDF (fiber and digestibility), and RFV (relative feed value, an overall quality figure).

Can I get the lab results for the hay I buy?

Yes. We keep the Fast Track 600 lab analysis on file for the current lot of the hay we grow, so you can review the numbers before you buy and match the forage to your horse's needs.
