Effect of phytase in pig diets with corn co-products

Because phosphorus in distillers dried grains co-products is well digested by pigs even if no microbial phytase is used, the addition of phytase leads to relatively little increase in phosphorus digestibility in these ingredients, and thus is not economical. By Ferdinando Almeida, graduate student and Hans Stein, professor at University of Illinois, USA Helping pigs digest more of the phosphorus that naturally occurs in the diet could provide a costeffective alternative to inorganic
