Dietary phosphorus in poultry: how low can we go?

Precision feeding improves the economics of production and reduces potential negative environmental impacts. Canadian researchers looked at how precise we can be when adding dietary phosphorus to poultry diets. Phosphorus − one of the most expensive nutrients in poultry feed − is an essential element for bodily functions, bone and egg shell formation. However, excessive faecal excretion of phosphorus has increasingly become an environmental issue due to the oversupply of phosphorus in lay
