`HW = "W" * 2 %`
Enter a value for all fields
The Daily Hay Amount for a Horse calculator computes the weight (HW) of a hay that a horse should eat per day based on its weight and a percent of body weight.
INSTRUCTIONS: Choose units and enter the following:
- (W) Weight of Horse
- (HP) Percent of a horse's weight for hay consumption.
Hay Weight(HW): The calculator returns the weight in pounds (lbs). However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for the daily weight of hay needed for your horse is:
`HW = W * HP`
where:
- HW = Weight of Hay for daily horse consumption
- W is the weight of the horse
- HP = Percent of Body Weight for Hay consumption.
An adult horse should eat 11.5 to 16 pounds of hay per day. This is based on a range of 1.5% to 3.0% of the horse's weight. The percentage is based on many factors.
- Is your horse over or underweight?
- How active is your horse? Obviously a heavily working farm horse will need to eat more than an animal that is mostly in the stable.
- Does your horse have a high metabolism?
- How cold is it? Your horse will need more energy to stay warm on bitter cold days.
Horse and Stable Calculators
- Weight of Horse: This is based on the girth and length of the horse.
- Daily Hay Weight for a Horse: This is based on the horse's weight and percent of body weight.
- Daly Bales of Hay for a Horse: This is based on the horse's weight, percent of body weight and weight of bales.
- How Long Hay will Last: This is based on the number of bales in the loft, number of horses, and the bales per day for the horses.
- How Much Hay: This estimates the amount of hay needed for a period of time based on the daily consumption per animal, the number of animals and the duration.
