Abstract
Methods and compositions for enhancement of phytate phosphorus utilization and treatment and prevention of tibial dyschondroplasia in animals, particularly poultry, by administering to animals a feed composition containing a hydroxylated vitamin D.sub.3 derivative. The vitamin D.sub.3 derivative is preferably administered to animals in feed containing reduced levels of calcium and phosphorus for enhancement of phytate phosphorus utilization. The vitamin D.sub.3 derivative is administered in combination with active phytase for further enhancement of phytate phosphorus utilization.
