Nutrient balance sheets (NBS) are used to estimate phosphorus loads produced by rearing facilities, but currently are not recognized in the Agricultural Operations Regulation (AOR). A project was set up in cooperation with Fédération des producteurs d’oeufs du Québec and a number of producers to test the nutrient balance sheet method as a tool for estimating phosphorus output from pullets and laying hens in case the AOR is amended. The project consisted of evaluating the phosphorus retention factor, the accuracy of the method, and “sensitive” parameters, and generating test criteria for producers. A guide presenting and explaining the results was published along with the necessary training materials.
