Claims
- 1. 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.
- 2. The composition of claim 1 wherein the concentration of vitamin D.sub.3 derivative is between 3 and 6 micrograms per kilogram feed.
- 3. The composition of claim 2 wherein the concentration of vitamin D.sub.3 derivative is approximately 5 micrograms per kilogram feed.
- 4. The composition of claim 1 wherein the animal feed has a calcium content of between 0.5 and 1.3% by weight.
- 5. The composition of claim 4 wherein the animal feed has a phosphorous content of between 0.4 and 0.9% by weight.
- 6. The composition of claim 1 further comprising active phytase.
- 7. The composition of claim 6 comprising an amount of phytase between 30 and 600 units per kilogram feed.
- 8. The composition of claim 1 wherein the animal feed is selected from the group consisting of poultry feed and swine feed.
- 9. 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.
- 10. The method of claim 9 wherein the animal feed has a calcium concentration of between 0.5 and 1.3% by weight.
- 11. The method of claim 10 wherein the animal feed has a phosphorus concentration of between 0.4 and 0.9% by weight.
- 12. The method of claim 9 further comprising adding active phytase to the feed.
- 13. The animal feed composition of claim 4 wherein the animals are poultry animals.
- 14. The animal feed composition of claim 13 wherein the animals are broilers.
- 15. The method of claim 10 wherein the animals are poultry animals.
- 16. The method of claim 15 wherein the animals are broilers.
- 17. 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 and active phytase.
- 18. The feed composition of claim 17 wherein the phytase is in an amount between 30 and 600 units per kilogram of feed.
- 19. A method of preparing an animal feed composition comprising the steps of adding to an animal feed 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 active phytase.
- 20. The method of claim 19 wherein the phytase is in an amount between 30 and 600 units per kilogram of feed.
