FAQs

How much hay does a horse need daily?

A horse needs a minimum of 1.5-2% of body weight in forage. A 500kg horse needs at least 7.5-10kg of hay daily as a foundation.

When should I add grain to the diet?

Add grain when hay alone cannot meet energy needs, typically for horses in moderate to heavy work, growing horses, or lactating mares.

How much water does a horse need?

Horses drink 20-40 liters (5-10 gallons) daily. This increases with work, hot weather, and lactation.

How many times a day should I feed?

Divide daily feed into 2-3 meals minimum. Horses are designed to eat frequently, so more small meals are better for digestion.

Should I use a complete feed?

Complete feeds are convenient but hay should still be offered for dental health and digestive function unless a horse cannot chew properly.
