- 1). Find a suitable bottle of oil to add to your horse's daily feed rations. Corn oil, soybean oil and safflower oil are all good choices.
- 2). Keep the bottle of oil in the barn to make it easier to add it to your horse's feed every day.
- 3). Remove the cap from the bottle of oil and pour the oil into the cap. A capful of oil is a good ration for the average-size horse, and adding that oil to the horse's feed on a daily basis can give him a shiny coat and a healthy glow.
