Question: how much does a horse eat compared to a cow?
Answer: Since horses eat more than cattle, a horse would eat more than 1 AUM of forage during a month. However, a sheep or a goat would eat less than 1 AUM of forage. An AUM can be thought of as a box of forage that weighs 900 lbs. or the tenure (the length of the grazing period) of the standard animal, a 1000 lb. cow.
