Abstract

The invention pertains to the use of a supplement for making metals (nutritionally) available to animals, said supplement comprising at least one compound selected from the group consisting of glutamic acid N,N-diacetic acid (GLDA), a metal complex of GLDA, a sodium salt of GLDA, a potassium salt of GLDA, methylglycine-N,N-diacetic acid (MGDA), a metal complex of MGDA, a sodium salt of MGDA, a potassium salt of MGDA, ethylenediamine N,N′-disuccinic acid (EDDS), a metal complex of EDDS, a sodium salt of EDDS, a potassium salt of EDDS, iminodisuccinic acid (IDS), a metal complex of IDS, a sodium salt of IDS, and a potassium salt of IDS.

First claim

The invention claimed is:

1. A method of making a metal nutritionally available to an animal comprising the step of providing the animal with a supplement incorporated in animal feed, animal drinking water, salt licks, or premixes therefor, wherein the supplement comprises at least one compound selected from the group consisting of glutamic acid N,N-diacetic acid (GLDA), a metal complex of GLDA, a sodium salt of GLDA, a potassium salt of GLDA, methylglycine-N,N-diacetic acid (MGDA), a metal complex of MGDA, a sodium salt of MGDA, and a potassium salt of MGDA.

2. The method according to claim 1 wherein the supplement comprises at least one anion selected from the group of anions of GLDA, or MGDA and at least one cation selected from the group consisting of calcium, magnesium, copper, zinc, iron, manganese, chromium, and cobalt cations.

3. The method according to claim 1 , wherein the metal is selected from the group consisting of zinc, copper, iron, manganese, cobalt, chromium, calcium, and magnesium.

4. The method according to claim 1 wherein the supplement comprises a metal complex of GLDA or a metal complex of MGDA.

5. The method according to claim 4 wherein the supplement comprises a zinc, manganese, iron or copper complex of GLDA.

6. The method according to claim 1 wherein the supplement is incorporated in animal feed and the animal feed further comprises a feedstuff from the group of legumes, forages, grain, leaves, or derivatives thereof.

7. The method according to claim 1 wherein the animals are domestic animals or aquatic animals selected from the group consisting of chickens, layers, turkeys, swine, cattle, sheep, goats, horses, cats, dogs, fish, or shrimp.

8. The method according to claim 1 wherein the supplement further comprises at least one compound selected from the group consisting of proteins, fats, carbohydrates, minerals, vitamins, vitamin precursors, and water or other edible liquids.

9. The method according to claim 1 wherein the supplement is chosen from a zinc or copper complex of GLDA.

10. The method according to claim 1 comprising (i) one or more compounds selected from the group consisting of a sodium salt of GLDA, a potassium salt of GLDA, a sodium salt of MGDA, a potassium salt of MGDA, a calcium complex of GLDA, a magnesium complex of GLDA, a calcium complex of MGDA, and a magnesium complex of MGDA; and (ii) one or more salts selected from the group consisting of a copper salt, a zinc salt, an iron salt, a manganese salt, a chromium salt, and a cobalt salt.

11. The method of claim 1 wherein the supplement comprises a metal complex of glutamic acid N,N-diacetic acid (GLDA) or methylglycine-N,N-diacetic acid (MGDA) wherein the metal is selected from the group consisting of copper, manganese, chromium, cobalt, magnesium, and calcium.

12. The method of claim 11 wherein the complex is Na 2 Cu-GLDA, K 2 Cu-GLDA, H 2 Cu-GLDA, NaKCu-GLDA, NaHCu-GLDA, KHCu-GLDA, Cu 2 -GLDA, Na 2 Zn-GLDA, K 2 Zn-GLDA, H 2 Zn-GLDA, NaKZn-GLDA, NaHZn-GLDA, KHZn-GLDA, Zn 2 -GLDA, Na 2 Mn-GLDA, K 2 Mn-GLDA, H 2 Mn-GLDA, NaKMn-GLDA, NaHMn-GLDA, KHMn-GLDA, Mn 2 -GLDA, NaCu-MGDA, KCu-MGDA, HCu-MGDA, NaZn-MGDA, KZn-MGDA, HZn-MGDA, NaMn-MGDA, KMn-MGDA, or HMn-MGDA.

13. The method of claim 1 comprising a step of adding the supplement to animal feed, animal drinking water, salt licks or premixes, wherein the supplement comprises (i) a metal complex of glutamic acid N,N-diacetic acid (GLDA) or methylglycine-N,N-diacetic acid (MGDA), or (ii) at least one compound selected from the group consisting of GLDA, a sodium salt of GLDA, a potassium salt of GLDA, MGDA, a sodium salt of MGDA, a potassium salt of MGDA.

14. The method of claim 1 , wherein the animal feed, animal drinking water, salt licks, or premixes therefor comprises the metal.

15. The method of claim 14 , wherein the animal feed, animal drinking water, salt licks, or premixes therefor has a reduced amount of the metal compared to animal feed, animal drinking water, salt licks, or premixes therefor that does not have the supplement.

16. The method of claim 1 , wherein the animal has a nutritional need for the metal.

17. The method of claim 1 , wherein the animal is provided with an effective amount of the supplement to make the metal nutritionally available to the animal.

18. The method of claim 13 wherein one or more salts selected from the group consisting of a copper salt, a zinc salt, an iron salt, a manganese salt, a chromium salt, and a cobalt salt is added to the animal feed, animal drinking water, salt licks or premixes along with the supplement.
