Available and retainable phosphorus of feedstuffs for broilers
Summary The project will determine biological availability of P in plant origin feedstuffs commonly used in Australian poultry diets (e.g., wheat, sorghum, barley, soybean meals, canola meals and millruns), and both Ca and P in meat and bone meals, Mono dicalcium Phosphate (MDCP) and dicalcium phosphate (DCP)) for broilers at 42 days of age. Phytase will be supplemented to the plant origin feedstuffs. The diets will be fed as mash form from 3742 days of age. The feed intake and excreta output will be recorded for last three days. At the end of experiment, the birds will be euthanized and ileal samples will be collected. Retainable and available P and Ca of the respective ingredients will be determined.
A comprehensive report with biologically determined available and retainable P contents for plant origin with or without phytase, both Ca and P for MBMs, MDCPs and DCP will be produced.
Program Chicken Meat
Research organisation The University of Queensland
Objective summary 1) Determine available/retainable Ca and P of respective feedstuffs in broilers at 42 days of age
2) Provide updated and essential information on biologically determined available/retainable Ca and P of feedstuffs to allow nutritionists to formulate diets to meet the exact Ca and P requirement of birds, reduce safety margin and cost for poultry production
3) Reduce P excretion and threat to the environment
