It has been demonstrated that the phosphorus (P) requirements of modern broilers are significantly lower than historical industry practice (Li et al., 2017). However, it is also apparent from these studies that the P requirement is dependent on the dietary calcium (Ca) concentration and whether the diet is supplemented with phytase. Most of the contemporary research has been conducted in the start ...

There has been much research recently to refine broiler requirements for calcium (Ca) and phosphorus (P), especially since the routine inclusion of phytase in broiler diets (Li et al., 2016). Phosphorus and Ca play significant roles in bone metabolism and vitamin D is also pivotal to maintaining bone integrity through the modulation of Ca metabolism (Li et al., 2017). The broiler requirement for v ...
