NSPases: the key to unlocking nutrients


The right combination of synergistic enzymes to target both soluble and insoluble fibres is key to unlocking nutrients and optimising digestion for successful animal performance. The solution lies in a targeted NSPase concept.

nimals need a certain amount of fibre in the diet, but it is important to consider the different types of dietary fibres used in diet formulation. Fibres come in both insoluble and insoluble forms and


are partly fermentable and non-fermentable, having an im- pact on nutrient digestion, water holding capacity and transit time. Soluble fibres create a so-called gel effect and contrib- ute to the development of viscosity in the small intestine, which is considered anti-nutritional as the increase of


viscosity limits the efficient absorption of nutrients. Insoluble fibres create a so-called nutshell effect, limiting the access of endogenous enzymes to the nutrients within the desired time frame and they carry away nutrients from the small intestine into the large intestine and caecum (see box).


Use of NSPases Most of the dietary fibre (both soluble and insoluble) in ani- mal diets is provided by non-starch polysaccharides (NSPs). The grains in animal diets typically represent about 50% of NSPs as well as 50% of the feed protein. By-products from grain and oil seeds are major protein sources and represent the other 50% of total protein and NSP level in animal diets. The downside is that NSPs often have anti-nutritional effects and thus a detrimental impact on digestion and animal per- formance. This is because NSP fibres bind or surround nutri- ents and dietary proteins, thereby hindering efficient absorp- tion. For an optimal break-down of NSPs, a sufficient quantity (threshold level) of appropriate enzymes (NSPases) is
