In today’s animal production systems, high and sustainable growth is necessary to compete in the global market. However, this is a real challenge with complex diets containing high amounts of cereal and oil seed by-products, the use of legumes and industrial by-products like DDGS, . It becomes even more challenging in young animals, like weaned piglets and broilers, as their digestive tract and endogenous enzyme production are not yet fully developed. As a result, impaired nutrient absorption and diarrhoea are commonly seen in practice. As part of the solution, enzyme supplementation has been proved to be very helpful to support the digestion of feed in young animals.
