Interpretive Summary:

Technical Abstract: There are three ways to improve phosphorus utilization by our poultry and livestock. 1. More exact measurement of the phosphorus requirement and use of phase- or group-feeding to more precisely meet the phosphorus requirement for different growth stages or production levels. 2. Use of phytase as a dietary additive to increase availability of phosphorus in grains. This applies to poultry and swine. 3. Use of plant breeding to reduce phytase content of grains, to incorporate phytase activity directly into the plant, and to lower phosphorus content of plants. The first two plant breeding methods would be potentially useful for poultry and swine, whereas the third method may have more application for beef and dairy animals.
