What is it about?
The further reducing the calcium (Ca) and available phosphorus (aP) contents of broiler diets have gained importance recently due to depletion of nonrenewable global inorganic phosphate deposits, unpredictable prices of inorganic phosphate additions, and environmental pollution. This paper adds to the body of research on the importance of starter diet and its Ca and aP contents. The reducing the Ca and aP contents (at the ratio of 36.5% and 31.0%, respectively) of the starter diet result in a decrease in feed intake and an improvement in feed efficiency without affecting broiler growth and bone health.

Why is it important?
As a result, the Ca and P requirements of broiler chickens during the starter period are lower than the recommendations in the standards.
Perspectives
To rear broilers successfully and to achieve optimum performance, the provision of accurate levels of the major minerals, especially calcium (Ca) and phosphorus (P) with the appropriate balance is vital. writing this article was a great pleasure as it has co-authors with whom I have had long-standing collaborations. This article also leads to broiler producer groups contacting me and ultimately to greater involvement in research of the macro minerals that are provided in poultry feed, both Ca and P levels and the Ca:P ratio.
