Protein feeders are used to feed protein to deer in order to supplemental their diets with the nutrition they need to remain healthy and grow. Just like a body builder uses protein to strengthen and improve over all mass in their body, feeding deer protein has the same effects. This is a great tool if you are interested in producing a strong quality herd of deer. Our protein feeders come in free choice, trough style, and electric versions, so you can feed as often or as regulated as you would like.
