Effects of Phytase and 1,25-Dihydroxycholecalciferol on Phytate Utilization and the Quantitative Requirement for Calcium and Phosphorus in Young Broiler Chickens

1996 Poultry Science  
Three experiments were conducted to determine the effects of supplementing 1,25dihydroxycholecalciferol [l,25-(OH)2D3] and a commercial phytase product on Ca and P requirements of 0-to 21-d-old broiler males. These experiments were conducted with four levels of dietary Ca and P in cornsoybean diets with and without supplementation of 5 Atg/kg of l,25-(OH) 2 D 3 , 600 units/kg of phytase, and the combination of these supplements. The results show that these levels of phytase and l,25-(OH)2D3 can
