Abstract

A method of enhancing a mineral level in an animal with reduced environmental impact can comprise orally administering a metal amino acid chelate to an animal, wherein the amino acid to metal molar ratio of the metal amino acid chelate is from about 1:1 to 4:1. The metal can contribute to a mineral level within the blood and tissues of the animal that is effective for stimulating growth of the animal to a greater degree than would be realized by administering the same amount of metal in the form of an inorganic metal salt. Additionally, the amount of the metal excreted in the feces of the animal can be less than would be present when administering the same amount of metal in the form of the inorganic metal salt. The metal amino acid chelate can also serve as a source highly bioavailable amino acids, so that the excretion of nitrates by the animal may be reduced while still promoting efficient growth.

Claims

1. A method of enhancing a mineral level in an animal with reduced environmental impact, comprising orally administering a metal amino acid chelate to an animal, wherein the amino acid to metal molar ratio of the metal amino acid chelate is from about 1:

1 to 4;

1, said metal contributing to a mineral level within the blood and tissues of the animal that is effective for stimulating growth of the animal to a greater degree than would be realized by administering the same amount of metal in the form of an inorganic metal salt, wherein the amount of the metal excreted in the feces of the animal is less than would be present when administering the same amount of metal in the form of the inorganic metal salt.

2. The method of claim 1, wherein the feces is substantially free of the metal due to the administration of the metal amino acid chelate, and wherein the feces would not be substantially free of the metal when administering the same amount of the metal in the form of the inorganic metal salt.

3. The method of claim 1, wherein the metal is a member selected from the group consisting of copper, zinc, manganese, calcium, magnesium, chromium, iron, and combinations thereof.

4. The method of claim 1, wherein the amino acid is a member selected from the group consisting of:

alanine, arginine, aparagine, aspartic acid, cysteine, cystine, glutamine, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, lysine, methionine, ornithine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, and dipeptides and tripeptides formed by any combination thereof.

5. The method of claim 1, wherein the metal amino acid chelate is coadministered with inorganic metal salts or vitamins.

6. The method of claim 1, wherein the metal amino acid chelate is coadministered with feed or is administered as a fortified feed.

7. The method of claim 1, wherein the metal amino acid chelate is coadministered with a liquid or is administered as a fortified liquid.

8. The method of claim 1, wherein the metal amino acid chelate is within a composition in particulate form.

9. The method of claim 1, wherein the animal is swine.

10. The method of claim 1, wherein the animal is ruminant.

11. The method of claim 1, wherein the animal is poultry.

12. The method of claim 1, wherein the animal is equine.

13. The method of claim 1, wherein the metal content of the feces in parts per million due to administering the metal amino acid chelate is reduced by 1 wt % to 70 wt % as compared to when the same amount of metal is administered in the form of the inorganic metal salt.

14. The method of claim 13, wherein the metal content of the feces in parts per million due to administering the metal amino acid chelate is reduced by 3 wt % to 50 wt % as compared to when the same amount of metal is administered in the form of the inorganic metal salt.

15. The method of claim 13, where the inorganic metal salt is selected from the group consisting of metal oxides or hydroxides, metal sulfates, metal chlorides, metal carbonates, and metal phosphates.

16. The method of claim 1, further comprising a preliminary step of determining an amount of metal needed to promote efficient growth of the animal.

17. The method of claim 16, wherein the step of administering includes delivering the amount of metal, while at the same time not substantially increasing the metal content of the feces compared to no metal administration.

18. The method of claim 1, wherein the amount of nitrates excreted in the feces of the animal is less than would be present if the animal ingested an amount by weight of amino acids from other dietary sources equal to that present in the metal amino acid chelate.

19. The method of claim 18, further comprising reducing the dietary protein fed to the animal from other dietary sources without reducing the rate of growth of the animal.

20. A method for facilitating the recovery of animal feces byproducts by reducing the amount of a metal in said feces byproducts, comprising:

orally administering a metal in the form of a metal amino acid chelate to an animal, wherein the amount of the metal administered is sufficient for stimulating growth of the animal while resulting in a lower amount of the metal in the feces of the animal than would result from administering the same amount of the metal in an inorganic salt form;

recovering the feces from the animal, said feces having a low enough concentration of metal to be acceptable for soil enrichment.

21. The method of claim 20, wherein the feces is substantially free of the metal.

22. The method of claim 20, wherein the metal is a member selected from the group consisting of copper, zinc, manganese, calcium, magnesium, chromium, iron, and combinations thereof.

23. The method of claim 20, wherein the amino acid is a member selected from the group consisting of:

alanine, arginine, aparagine, aspartic acid, cysteine, cystine, glutamine, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, lysine, methionine, ornithine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, and dipeptides and tripeptides formed by any combination thereof.

24. The method of claim 20, wherein the metal content of the feces in parts per million due to administering the metal amino acid chelate is reduced by 1% to 70% as compared to when the same amount of metal is administered in the form of an inorganic metal salt.

25. The method of claim 20, wherein the metal content of the feces in parts per million due to administering the metal amino acid chelate is reduced by 3% to 50% as compared to when the same amount of metal is administered in the form of an inorganic metal salt.

26. The method of claim 20, wherein the animal is swine.

27. The method of claim 20, wherein the animal is ruminant.

28. The method of claim 20, wherein the animal is poultry.

29. The method of claim 20, wherein the animal is equine.

30. The method of claim 20, wherein the amount of nitrates present in the feces is less than would be present if the animal had ingested an amount by weight of amino acids from other dietary sources equal to that present in the metal amino acid chelate.

31. The method of claim 20, further comprising the step of enriching soil with the feces after the recovering step.

32. A feed that provides a metal to a animal in a highly bioavailable form, comprising one or more metal amino acid chelates, where the amount of metal the animal ingests by eating the feed contributes to stimulating growth of the animal to a greater degree than the same amount of metal is ingested by the animal in the form of an inorganic metal salt, and where the amount of metal excreted in the feces of the animal is less than would be present when the same amount of metal is ingested by the animal in the form of the inorganic metal salt.

33. The feed of claim 32, wherein the metal is a member selected from the group consisting of copper, zinc, manganese, calcium, magnesium, chromium, iron, and combinations thereof.
