Frequently Asked Questions

How much hay does a horse eat per day?
A horse should eat 1.5-2.5% of its body weight in forage daily. For a 1,000 lb horse, this is 15-25 lbs of hay per day. The exact amount depends on workload, body condition, hay quality, and pasture access.
Can a horse eat too much hay?
Most horses self-regulate hay intake well, and free-choice grass hay is generally safe. However, horses prone to obesity or metabolic issues (insulin resistance, Cushing's) may need restricted hay amounts. Alfalfa should be limited due to high calorie and protein content.
How should I store hay?
Store hay in a dry, well-ventilated area off the ground (on pallets). Keep it away from direct sunlight and moisture. Properly stored hay maintains quality for up to a year. Never feed moldy or dusty hay as it can cause respiratory problems and colic.
