Improved broiler phosphorus utilization and transporter gene expression

Phosphorus (P) is an expensive feed ingredient and there is a scarcity of global P reserves. There is a need to improve P utilization by broilers. The use of phytase has significantly improved P utilisation by increasing phytate digestion and therefore the amount of P available for absorption. Previous studies have shown that the efficiency of P absorption in broilers is low. The aim of this project is therefore to maximise P absorption by delineating the interrelationship between dietary P levels, dietary phytase addition and gene expression, especially transporter genes. This will allow us to develop dietary strategies to enhance P absorption and will lead to improved P utilization, reduced costs of production and lower environmental impact of poultry waste.
