One of its advantages over oats is its higher energy content and lower protein content. However, one undisputed disadvantage of maize is its hard structure, which makes it difficult to chew and means that some of the valuable ingredients cannot be digested properly. However, if maize is hydrothermally digested with moist heat, the resulting corn flakes unfold their advantages in horse feeding: flaking considerably increases the digestibility and digestibility of maize and makes it much more palatable. Use corn flakes to enhance the usual concentrate ration or as a rich basis for a customised manger feed. By the way: 0.8 kg of maize replaces approximately 1 kg of oats in terms of energy value.
