What role does chitin play in animal feeds?

Chitin serves a significant role in animal feeds primarily as a fiber source, which can positively influence gut health. Found in the exoskeletons of crustaceans and the cell walls of fungi, chitin is not digestible by many animals but can have beneficial effects when included in their diet. As a fiber, it can promote digestive health by supporting the growth of beneficial gut bacteria, enhancing the overall function of the gastrointestinal tract. This contribution to gut health can lead to improved nutrient absorption and overall well-being in animals.

Given its role as a non-digestible fiber rather than a carbohydrate, protein, or vitamin source, it does not function as a primary energy source, protein supplement, or provide vitamins. Thus, its unique properties as a source of dietary fiber are crucial for promoting animal health, making the choice highlighting its impact on gut health particularly accurate.
