How Much Hay Does a Horse Waste? What It Costs You a Winter
Horses fed loose round bales waste 30–50% of the hay. Here is where it goes, what it costs per winter in real dollars, and what each feeding method actually saves.
Short answer: a horse fed a round bale on the ground wastes 30–50% of it, and by wastes we mean trampled, slept on, peed on, or blown into the fence. Inside a poly ring with a slow-feed net, that drops to 2–4%. On a barn that goes through 20 bales a winter at $110 a bale, the difference is roughly $600 to $1,000 a year that either goes into a horse or into the mud.
We run horses on our own place outside Sherwood Park, and we fed loose bales for years before we did this math. Here it is, so you do not have to learn it the way we did.
Where the hay actually goes
Watch a herd on an open bale for a day and you will see all five of these.
- Trampling. Horses pull hay out, drop half of it, and stand on it. Once it is underfoot they will not eat it.
- Bedding. The soft pile around a bale is the most comfortable spot in the paddock. They lie in it, and then they will not eat it.
- Manure and urine. Same reason. Horses eat where they stand, and they go where they stand.
- Wind. In an Alberta paddock a loose flake is gone by noon.
- Sorting. Given a whole bale, a horse picks the leafy bits and leaves the stems. What is left gets rained on and rots.
Extension services that have measured this put loose-fed round bale waste at 30–57%. Our own experience with an unprotected bale on frozen ground in January was about a third. Call it a third and you will not be far off. We wrote up the side-by-side a few years ago in Poly Hay Ring vs Free Choice.
The math on your barn
Three numbers: bales per winter, price per bale, and how you feed.
| Feeding method | Typical waste | On 20 bales at $110 |
|---|---|---|
| Loose on the ground | 30–50% | $660–$1,100 lost |
| Steel ring, no net | 15–25% | $330–$550 lost |
| Covered feeder | 8–12% | $175–$265 lost |
| Poly ring with slow-feed net | 2–4% | $45–$90 lost |
So switching from the ground to a ring with a net saves around $600–$1,000 a year on a 20-bale barn. A 40-bale boarding barn doubles that. The Adjustable Poly Hay Ring with net is $1,050.95 once. Put your own numbers in the hay-waste calculator and it will tell you how many winters to payback. For most people it is one.
Why a ring plus a net beats either one alone
A ring keeps the bale off the ground and the horses on the outside. That handles trampling, bedding and manure. It does nothing about sorting or wind.
A net over the bale handles the rest. Horses pull small mouthfuls through the mesh instead of yanking out a flake and dropping most of it. Nothing blows away because nothing is loose. And because the bale lasts longer, they stop bolting it. There is more on why slow feeding is easier on the gut in 5 Benefits of Slow Feeders.
Net alone, on the ground, still gets stood on and peed on. Ring alone still gets sorted and scattered. Together is where the 2–4% number comes from.
Cattle, goats, sheep, minis
Same problem, different scale.
- Cattle waste less by sorting and more by trampling. A ring with 2.75" mesh is the usual setup.
- Goats and sheep climb into anything they can. A 24" Mini ring keeps them on the outside and still fits a full round bale.
- Minis and ponies are the worst sorters of the lot. The Mini with 1.5" mesh slows them down and keeps an easy keeper from eating the whole bale in a week.
What we do on our own place
Two full-size rings with 1.5" nets for the riding horses, one Mini for the ponies. A 6×6 bale that used to last four days on the ground lasts six to seven in the ring, and the paddock around it stays clean enough to walk through in April. We have not bought a steel ring since.
Uncle Jeeter says: "You are not buying a feeder. You are buying back the third of every bale you were already paying for."
Questions people ask
Do hay nets damage teeth?
Grazing wears teeth too, that is what they are for. The real dental and gut risks come from the opposite problem: long gaps with no forage. A properly sized net keeps hay in front of them longer. Bad mesh sizing and hanging a small net at eye height cause the problems people blame on nets. On a round bale in a ring the net sits at ground level, which is how they would eat on pasture. See 11 tips to prevent damage with slow feeder nets.
Does a ring slow eating too much?
No. With 1.5" or 2" mesh a bale lasts days longer and the horses eat all day instead of in three sittings. That is closer to how they are built to eat.
Is wasted hay useful as bedding?
Only if you like mouldy bedding. Trampled hay holds water and rots, and it is not straw. For actual bedding, read the difference in shavings.
Can I add a net to a ring I already own?
Yes. The Net Topper is the net only, and a pipe kit mounts it on an AGI poly ring.
Will a poly ring crack at −30?
The AGI rings are UV-stabilized and built for prairie winters. Ours have been through five.
