What is digestibility index?

The digestibility index is a measure used to assess the extent to which a food or feed can be broken down and absorbed by the digestive system. It is often expressed as a percentage, indicating how much of a particular nutrient, such as carbohydrates, proteins, or fats, is digested and utilized by the body. Higher digestibility indexes suggest that a food is more easily assimilated, making it more beneficial for nutritional purposes. This index can vary between different foods and is important in fields like nutrition, animal feed formulation, and food science.
