Sunflower meal is the byproduct that remains after removing oil from sunflower seeds. The nutrient content of sunflower meal varies with the amount of hull included in the meal. Sunflower seed meal is a safe feed for mature horses, but it may decrease grain mix palatability if included at high levels.
Disadvantages: Sunflower meal has a high phosphorus content which offsets the Ca:P balance in horses unless they are provided with additional calcium supplementation.
