How to Calculate Hay Rations and Winter Stockpiles
Horses are non-ruminant hindgut herbivores requiring continuous forage intake to buffer stomach acid and prevent gastric ulcers.
Daily Lbs per Horse = Weight × Intake % × Waste Factor
Winter Bales = (Daily Herd Lbs × Winter Feed Days) / Bale Weight
Feeding on the ground without a feeder leads to 20% to 30% waste from trampling, urine, and mud contamination. Using slow-feeder nets reduces waste to under 10%.
Frequently Asked Questions
How many flakes of hay are in a 50 lb bale?
A 50 lb 2-string small square bale typically contains 10 to 14 flakes (each weighing roughly 3.5 to 5.0 lbs).
How many round bales equal one small square bale?
One standard 800 lb 4x5 round bale equals approximately 16 standard 50 lb small square bales.
Can a horse survive on pasture alone in winter?
In snow-covered northern climates, dormant pasture grasses lack protein, calories, and vitamin A. Supplemental grass or legume hay is strictly mandatory once temperatures drop below freezing.
