Assess Your Horses Weight, Condition and Needs:
In order for any nutrition program to be effective it has to serve the purpose for the animal you are feeding. Feeding a Shetland pony a draft horse diet is not only incorrect but also dangerous.
To know what and how much to feed you first need to know your horse’s weight, his current body condition and his nutritional needs.
I say it 20 times a week “Feed by weight not volume” and you will see it again under “W” later in the year. If the rule of thumb is 1.5-2% of your horse’s body weight in feedstuffs per day then you must know the body weight to calculate the percentage.
