Assessment of potential interactions between phytase and glycosidase enzyme supplementation on nutrient digestibility in broilers.

The effects of microbial 3-phytase and glycosidase enzymes, and their interactions, on energy values and nutrient digestibility in diets rich in nonstarch polysaccharides (NSP) were studied in diets based on corn, wheat, or barley. Four diets were prepared with each cereal grain. One had no enzymes, a second had 500 units of phytase, a third had glycosidase enzyme, and a fourth had phytase and glycosidase.
