Effect of high phytase levels on growth performance and calcium and phosphorus metabolism in broilers fed a non-inorganic phosphorus diet
The effects of high phytase levels on growth performance and calcium (Ca) and phosphorus (P) metabolism in broilers fed non-inorganic P diets were investigated. A total of 600 one-day-old broilers were assigned to either a control diet or a non-inorganic P diet supplemented with one of two commercial phytases (P1 and P...
