Non-starch polyssacharide (NSP) degrading enzymes, bacterial endoxylanase in particular, still prove to be very cost effective, even in combination with superdosing of phytase.
Phytase supplementation is not just about liberating phosphorous, as recent publications have shown. The presence of phytate (IP6) in the GI-tract also leads to poor digestion of protein and minerals, increased mucus production, and in general a worse intestinal health. Besides phytate itself, the degradation products of phytate, such as IP5, IP4 and IP3, also exert similar anti-nutritional effects in the animal. Initially, phytase action is degrading one anti-nutrient and simply replacing it...
