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,
Claims20
An animal feed composition comprising a vitamin D.sub.3 derivative selected from the group consisting of 1,25-dihydroxycholecalciferol;
- 1,25-dihydroxy-26,27-hexadeuterocholecalciferol;
- 1-hydroxycholecalciferol;
- 1,24,25-trihydroxycholecalciferol;
- and 1,25-dihydroxy-24-fluorocholecalciferol;
- 25-hydroxycholecalciferol;
- and mixtures thereof in combination with an animal feed for growing animals, wherein the concentration of vitamin D.sub.3 derivative is between 1 and 10 micrograms per kilogram feed for growing animals, and is in an amount effectively inhibiting development of tibial dyschondroplasia in growing animals ingesting the feed.
A method of preparing an animal feed composition comprising the steps of adding to an animal feed for a growing animal a vitamin D.sub.3 derivative selected from the group consisting of 1,25-dihydroxycholecalciferol;
- 1,25-dihydroxy-26,27-hexadeutero-cholecalciferol;
- 1-hydroxycholecalciferol;
- 1,24,25-trihydroxycholecalciferol;
- and 1,25-dihydroxy-24-fluorocholecalciferol;
- 25-hydroxycholecalciferol;
- and mixtures thereof, wherein the concentration of vitamin D.sub.3 derivative is added to between 1 and 10 micrograms per kilogram feed for growing animals, and is in an amount effectively inhibiting development of tibial dyschondroplasia in growing animals ingesting the feed.
