Despite widespread uptake across the poultry industry, considerable debate continues around how to achieve best results with fiber-degrading feed enzymes.Much of that debate relates to the complexity and variety of potential non-starch polysaccharide (NSP) substrates such enzymes can target, a situation which has led to a growing body of literature advocating the use of products with multiple NSP enzyme activities.

Very wet wheat, harvested after poor weather, is often unsuitable for human food uses. Such harvest conditions often result in germination and increased levels of amylase and protease. These enzymes are related to decreased loaf size and poor gluten strength in bakery products and, as a result, this damaged wheat may be sold into the animal feed market.
