Indigestion: An overlooked factor in animal nutrition?

Many articles on young animal feed composition focus on digestibility of ingredients. It is interesting, however, to take the opposite view. What happens when trying to measure indigestibility and thus quantify what is in the feed that young animals don’t need? When evaluating feed ingredients, digestibility of nutrients as a measure of quality and potential in feed formulation is typically used. These values are published in various nutrition guides and are often the target of research proje
