What does a hay analysis actually tell you?
A hay analysis tells you how much energy, protein, sugar, starch and minerals are in the hay you're feeding — the numbers that shape a horse care and feeding plan. It's the single best tool for knowing what your horse is actually eating instead of guessing. But it won't tell you about amino acid quality — and that's the part that matters most for coat, hooves and topline.
Here in the Black Hills, where a lot of us buy hay by the ton off a neighbor's field, a test takes the mystery out of your feeding program. Let's walk through what those numbers mean and where the blind spots are.
How do I read the numbers on a hay report?
When your report comes back, a few lines do most of the work.
**Crude protein** is the big one people look at first. It's an estimate of total protein, calculated from the nitrogen in the sample. Grass hay around here usually runs 8 to 12 percent, alfalfa higher.
**ADF and NDF** tell you about fiber and how digestible the hay is. Higher numbers mean coarser, more mature hay that your horse gets less out of.
**NSC** — the sugars and starch — matters a lot if you've got an easy keeper or a metabolic horse. Under about 10 to 12 percent is the range many of those horses need.
**Minerals** like calcium, phosphorus, and the trace minerals round it out, and they help you decide whether you need a ration balancer on top of hay.
That's a solid picture. The trouble is what one of those lines quietly hides.
Why don't amino acids show up on my hay test?
Here's the catch with crude protein: it measures how *much* protein is there, not how *usable* it is. A horse doesn't build muscle, hoof or hair from "protein" in general — it builds from the specific amino acids inside that protein, in the right amounts. The first ones to run short are lysine and methionine, and grass hay is usually low in both.
So you can have a hay report showing a respectable 11 percent crude protein and still have a horse with a flat topline and slow-growing hooves, because the *quality* of that protein is poor. Two hays with the same protein number can feed a horse very differently, which is exactly the gap we dig into in our piece on the amino acid difference between grass hay and alfalfa.
A standard hay analysis almost never lists individual amino acids. The lab test for that is specialized, expensive, and most labs don't offer it as part of a normal panel. So even a good report leaves this part of the story blank.
What do I do about the blind spot?
Once you know your hay's numbers, you can fill the gaps on purpose instead of by accident. If the report shows low protein and low minerals, a ration balancer might be your answer — and our note on choosing between an amino acid supplement and a ration balancer can help you sort that out.
But if your hay tests fine on paper and your horse still has a dull coat, weak hooves, or a topline that won't build, the missing amino acids are the likely culprit. That's the exact gap Equine Amino Boost is built to close — a daily pellet that adds the lysine, methionine and threonine grass hay tends to fall short on, so the protein your horse already eats can actually do its job.
Test your hay, read it honestly, and treat the amino acid line as blank until you've filled it. If you're not sure what your report is telling you, send us a note — we're happy to look it over. Pete does love a good spreadsheet.
