Abstract

Abstract The levels of nutritionally essential metals in biological tissue are improved by administering corrective dosages of the metals found to be deficient, the metal being administered in the form of metal proteinates. General health of animals is improved by increasing the levels of metals in biological tissues through the administration of multiple metals in the form of metal proteinates.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 99 words
A method of raising the levels of essential bivalent metals in the tissues of animals which comprises administering to said animal an effective amount of exogenously synthesized metabolically assimilable metal proteinates, said proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqueous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 2
Independent Claim 99 words
A method of raising the levels of essential bivalent metals in the tissues of animals which comprises administering to said animal an effective amount of exogenously synthesized metabolically assimilable metal proteinates, said proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqueous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 3
Dependent Claim 38 words
A method according to claim 1 wherein the effective amount of each metal proteinate is in a dosage effective to correct an existing metal deficiency in the animal during the period over which the metal proteinate is administered.
Claim 4
Dependent Claim 14 words
A method according to claim 2 wherein the metal proteinate is an iron proteinate.
Claim 5
Dependent Claim 28 words
A method according to claim 2 wherein the metals in the metal proteinates are selected from the group consisting of calcium, magnesium, zinc, iron, manganese, copper and cobalt.
Claim 6
Dependent Claim 19 words
A method according to claim 4 wherein the metal proteinates are administered in the form of a dietary supplement.
Claim 7
Dependent Claim 30 words
A method according to claim 5 wherein the existing metal deficiency is determined by analysis of the tissues of the animal to which the metal proteinates are to be administered.
Claim 8
Dependent Claim 25 words
A method according to claim 6 wherein the tissues analyzed are selected from the group consisting of hair, feathers, hoofs, horns, skin, flesh and blood.
Claim 9
Dependent Claim 34 words
A method for treating anemia in piglets which comprises administering an effective dosage of a metal proteinate according to claim 1 to a farrowing sow during the latter stages of pregnancy and during lactation.
Claim 10
Dependent Claim 32 words
A method according to claim 8 wherein the metal protein is an iron proteinate in admixture with other metal proteinates selected from the group consisting of magnesium, zinc, copper, and cobalt proteinates.
Claim 11
Dependent Claim 14 words
A method according to claim 8 wherein the metal proteinate is an iron proteinate.
Claim 12
Dependent Claim 98 words
A composition for raising the levels of essential bivalent metals in tissues of animals comprising an animal feed and an effective mixture of exogenously synthesized metabolically assimilable metal proteinates, said metal proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides, and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqueous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 13
Dependent Claim 98 words
A composition for raising the levels of essential bivalent metals in tissues of animals comprising an animal feed and an effective mixture of exogenously synthesized metabolically assimilable metal proteinates, said metal proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides, and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqueous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 14
Dependent Claim 24 words
A composition according to claim 11 wherein the metals are selected from the group consisting of calcium, magnesium, zinc, iron, manganese, copper and cobalt.
Claim 15
Dependent Claim 98 words
A composition for raising the levels of essential bivalent metals in tissues of animals comprising a lactose diluent and an effective amount of exogenously synthesized metabolically assimilable metal proteinates, said meal proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqeuous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 16
Dependent Claim 98 words
A composition for raising the levels of essential bivalent metals in tissues of animals comprising a lactose diluent and an effective amount of exogenously synthesized metabolically assimilable metal proteinates, said meal proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqeuous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 17
Dependent Claim 106 words
A composition for raising the levels of essential bivalent metals in tissues of animals comprising in addition to a feed a dietary supplement containing an effective amount of a mixture of exogenously synthesized metabolically assimilable metal proteinates, said metal proteinates being in the form of chelates of said metals with one or more protein hydrolysates selected from the group consisting of polypeptides, peptides and amino acids wherein said proteinates are formed by dissolving salts of said metals in an aqueous solution containing the protein hydrolysates and adding sufficient base to raise the ph to a value between about 7.5 and 10 to precipitate said metal proteinates.
Claim 18
