How much hay per horse per day should I plan for?

The arithmetic for planning a winter's hay, how to judge a load before you commit, and what people actually do in the in-between stretch when pasture is fading but it isn't winter yet.

This is general information, not veterinary advice. Every horse is different. Talk to your vet before changing a feed, health, or care program -- especially for a senior, a hard keeper, or a horse with a known condition.
The short answer

Plan on roughly 1.5% to 2% of body weight per day in forage. For a 1,000 lb horse with no grazing, that's about 15 to 20 lbs of hay a day, or a little under half a small square bale. Hard keepers, seniors, and horses living out in cold weather run at the higher end.

Hay planning is one of the few genuinely arithmetic problems in horse keeping, which makes it easier than it feels. Get the daily number, multiply by the days, add a margin, and you have your answer before the price goes up in January.

The winter math

How much hay do I really need per horse to get to March without a scramble?

Take the daily amount, multiply by the number of days you'll be feeding, and add 15% to 20% for waste and a long winter. At 20 lbs a day from November through March, roughly 150 days, that's about 3,000 lbs per horse, plus margin -- call it 3,500 lbs, or about 70 fifty-pound bales.

Two things blow the estimate. The first is waste -- hay fed on the ground in a muddy paddock can lose a quarter of the bale. A slow feed net cuts that substantially and makes the same load go further.

The second is the tail of the season. People buy for a winter that ends in March and then feed through a cold, bare April. Buy for longer than you think.

Judging a load

How can I tell if this year's hay is actually good before I commit to a load?

Open a bale, don't judge the stack. Good hay smells sweet and slightly grassy, is green to pale green inside, feels soft rather than coarse, and has fine stems with leaf still attached. Reject anything that smells musty or sour, feels warm in the bale, is dusty, or has visible white or grey mould.

Smell is the fastest signal and the most reliable. Musty means it was baled damp, and damp hay grows mould you can't always see.

Ask to open a bale from the middle of the stack rather than the one on top, and ask when it was cut and whether it got rained on. A seller who won't let you open a bale is telling you something.

If you're buying a large load or feeding horses with respiratory or metabolic issues, a forage analysis is worth the modest cost, and your vet can help you read it.

The in-between

Pasture is starting to disappear but we're not on full winter hay yet. How do people handle the in-between?

Start supplementing before the pasture is actually gone rather than after. Most people begin putting hay out once grazing stops keeping condition on, usually a few weeks before it looks bare, then increase gradually as pasture declines. Slow, early changes are easier on a horse's gut than an abrupt switch.

Watch the horses rather than the calendar. Horses grazing constantly without gaining, or starting to drop condition, are telling you the pasture has stopped paying its way.

Autumn pasture also has its own risk: cool nights followed by sunny days can raise sugar levels in grass, which matters a great deal for laminitis-prone horses. If you have one, this is a conversation to have with your vet before the season turns, not after.

Any significant change in forage is worth making over a week or two rather than overnight.

Make the load last

Waste is the cheapest hay you'll ever buy back

Nets, feeders, and dry storage do more for your hay budget than shopping around on price does.
