Horse calculators
Horse keeping runs on numbers nobody writes down. How much hay, how many bales, how much more in a cold week, how much of it ends up trampled into the mud.
Every tool here shows its working, gives a range instead of a falsely precise single number, and cites the university research behind each figure it uses.
Calculators
Hay calculatorHow much hay does a horse need per day?Weight, workload, pasture and temperature in — pounds, bales and flakes out, for a day, a month or a whole winter. Handles the winter uplift, dry matter and feeding waste that other tools skip.Open the calculatorGrain calculatorHow much grain should I feed my horse daily?Works out the gap your forage leaves rather than a percentage of body weight — so the answer for most horses is none. Converts to scoops, bags and meals, and flags the per-meal limit that causes colic.Open the calculator
Guides
Does it need grain?Do horses need grain every day?Most horses do not need grain on any day. Work out the gap your forage leaves and for a mature horse in light work it is usually zero — here is when that changes.Read the guide
Scoop weightsHow much does a scoop of horse feed weigh?Between 0.89 and 1.53 lb per quart across 49 measured products. Conversion tables by feed form, scoop size, bag and kilogram — plus how to weigh your own.Read the guide
Choosing a feedWhat kind of grain should I feed my horse?Corn carries 18% more energy per pound than oats, and published tables get beet pulp and oat hulls badly wrong. What the directly measured figures say about each option.Read the guide
Senior horsesHow much grain should I feed my senior horse?The same arithmetic as any adult horse — senior horses have no separate published requirements. What changes is the mouth, and a hard 5 lb limit on any single meal.Read the guide
Feeding limitsHow much grain can you feed a horse per day?Three separate ceilings, and the one that catches people is on the meal rather than the day. 12 lb of grain is unremarkable in three feeds and dangerous in one.Read the guide
Feeding by the scoopHow many scoops of grain should I feed my horse?There is no number of scoops — a quart of feed weighs anywhere from 0.89 to 1.53 lb. Work out the pounds first, then convert with your own scoop, and mark it.Read the guide
