How Much to Feed a Senior Horse: Amounts & Portions
How much to feed a senior horse: forage at 1.5 to 2 percent of body weight, how to weigh feed, meal frequency, and body condition tips, with a feed weight calculator.
How much to feed a senior horse comes down to one durable rule and a lot of fine-tuning. The rule is to feed roughly 1.5 to 2 percent of body weight in forage or forage replacement every day. The fine-tuning is reading your horse's body and adjusting from there, because two horses of the same weight can need very different amounts depending on their teeth, metabolism, workload, and the weather.
This guide gives you the baseline numbers, shows how to weigh feed so the numbers mean something, and explains how to use body condition to dial them in. For a personalized starting target based on your horse's weight, try our feed weight calculator, then use the principles below to adjust.

Start With the Forage Baseline
The foundation of any horse's diet is forage, and the standard target is 1.5 to 2 percent of body weight per day in forage or forage replacement, measured by weight of dry feed. For a typical 1,000-pound horse, that is about 15 to 20 pounds of hay, or the same weight of soaked hay pellets, cubes, and beet pulp for a horse that can no longer chew hay. Easy keepers sit toward the lower end of the range, while hard keepers and horses working through cold weather sit toward the top.
This forage figure is the base. Concentrates like a senior feed or balancer are added on top of it at their own feeding rates, not counted within the forage total, unless a complete senior feed is replacing forage entirely.
Weigh, Do Not Guess
Percentages of body weight only help if you know two weights: how much your horse weighs and how much your feed weighs. Most owners are surprised how far their eyeball estimate is off.
- Body weight: A weight tape around the girth gives a workable estimate. Use the same tape and technique each time so the trend is meaningful, and write the number down.
- Hay weight: Weigh a few flakes of your hay on a luggage or kitchen scale. Flakes vary widely, so know what an average flake of your hay actually weighs.
- Feed weight: Weigh a level scoop of your pellets or feed once. A scoop is a volume, not a weight, and different feeds weigh different amounts per scoop.
Once you know these numbers, you can feed by weight with confidence. Our feed weight calculator turns your horse's weight into a daily forage target to start from.
Meal Frequency for Older Horses
How you split the day matters as much as the total. Horses evolved to eat fiber almost continuously, and a senior's aging gut does best when it is never empty for long. Feed at least two meals a day, and more for horses on concentrates or soaked forage replacements. Horses living on mashes, because their teeth can no longer handle free-choice hay, usually need three or more feedings spread through the day to mimic steady grazing and protect against ulcers and colic.
Free-Choice Hay Versus Measured Meals
For a horse that holds a healthy weight, near-constant access to grass hay is ideal, since it keeps the gut full and the horse occupied. The exception is easy keepers and metabolic horses, who can balloon on unlimited forage. For them, a slow-feed hay net stretches a measured, controlled amount of hay across many hours, slowing intake without leaving the horse standing at an empty manger. Decide between free-choice and measured feeding based on your horse's body condition, not convenience.
Body Condition Beats the Scoop
Numbers get you close, but your horse's body confirms whether you are right. Learn the Henneke body condition score, a 1 to 9 scale, and aim to keep most seniors around a 5 to 6, with a little extra cover going into winter. You should be able to feel the ribs under a light layer of fat without seeing them, and the topline, withers, and tailhead should be neither sharp nor buried in fat. If your horse is drifting thinner, increase the ration and check for medical causes; if it is gaining a cresty neck or fat pads, cut back and watch for metabolic issues.

Reassess as Your Horse Ages
There is no single permanent number. A horse in its late teens that holds weight easily may need less as its workload drops, while a horse in its late twenties often needs more calories and more frequent meals just to maintain condition as muscle and digestive efficiency decline. Reassess the ration a few times a year, especially at the change of seasons and after any dental work or illness. Weigh, watch body condition, and adjust gradually rather than setting the feed once and forgetting it.
The Bottom Line
Start by feeding 1.5 to 2 percent of your senior horse's body weight in forage or forage replacement each day, weigh both your horse and your feed so the percentage is real, and split the ration across two or more meals. Use free-choice hay for horses that hold weight and slow-feed nets or measured meals for easy keepers. Let the Henneke body condition score and a regular weight tape guide every adjustment. Begin with our feed weight calculator, then watch your horse, not just the scoop.

Frequently Asked Questions
How much should a senior horse eat per day?
As a baseline, feed 1.5 to 2 percent of body weight in forage or forage replacement daily. For a 1,000-pound horse that is roughly 15 to 20 pounds of dry feed. Hard keepers and horses in cold weather sit toward the higher end, easy keepers toward the lower. This is forage weight, with concentrates and supplements added on top per their feeding rates. Use our feed weight calculator for a starting target, then adjust to body condition.
How do I weigh my horse's feed?
Weigh it rather than measuring by scoop, because a scoop of pellets, hay, and grain all weigh different amounts. Use a kitchen or luggage scale to weigh a typical flake of hay and a level scoop of feed once, then feed by those known weights. For body weight, a weight tape around the girth gives a usable estimate. Weighing removes the guesswork that leads to slow over or underfeeding.
Should senior horses have free-choice hay?
Many do well with free-choice or near-constant forage, since horses are built to eat fiber more or less continuously and an empty gut raises ulcer and colic risk. The catch is easy keepers and metabolic horses, who can gain dangerous weight on unlimited forage. For them, a slow-feed hay net or measured meals stretch a controlled amount of hay across the day. Match the approach to your horse's body condition.
How many times a day should I feed an older horse?
Spread feed across at least two meals, and ideally more for horses on forage replacements or concentrates. Several smaller meals match a horse's natural grazing pattern, are easier on aging digestion, and reduce the risk of ulcers and colic from long empty-gut gaps. Horses on soaked mashes usually need three or more feedings a day, since they cannot graze hay free-choice the way a horse with good teeth can.
How do I know if I am feeding the right amount?
Let body condition decide, not the scoop. Learn the Henneke body condition score and aim to keep most seniors around a 5 to 6 out of 9, feeling ribs under a light cover without seeing them. Run a weight tape every couple of weeks and write the number down, since slow change is hard to see by eye. If condition drifts in either direction, adjust the ration and involve your vet.
Do senior horses need more or less feed than younger horses?
It varies. Some older horses become easy keepers as work drops and need less, while many late-life seniors lose muscle and digest less efficiently and need more calories just to hold weight. The forage baseline of 1.5 to 2 percent of body weight still applies, but where your horse falls in that range, and how much concentrate it needs on top, depends on the individual. Reassess a few times a year as needs change.
