Abstract
Abstract 1:1 Zinc methionine complex salts having the formula [CH3SCH2CH2CH(NH2)COO.Zn<++>]wX wherein X is an anion and w is an integer equal to the anionic charge of X. These are useful nutritional supplements, both for animals and humans, in that they provide a readily-available source of the zinc ions necessary for dietary balance and provide methionine, an essential amino acid, in a form which provides for body conversion of more of the methionine to protein than does the simple feeding of the compound methionine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A method of enhancing the nutrition and health of animals and humans by effectively increasing the absorption, distribution and utilization of zinc and methionine within the body system of said animals and humans, said method comprising feeding, as a dietary supplement of zinc and methionine, a diet supplementing effective amount of complexed salts of the formula: [CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.sup.. Zn.sup.+ .sup.+].sub.w X wherein X is an anion which does not interfere with the effective increasing of absorption, distribution and utilization of zinc and methionine within the body system, and w is an integer equal to the anionic charge of X.
Claim 2
Independent Claim
101 words
A method of enhancing the nutrition and health of animals and humans by effectively increasing the absorption, distribution and utilization of zinc and methionine within the body system of said animals and humans, said method comprising feeding, as a dietary supplement of zinc and methionine, a diet supplementing effective amount of complexed salts of the formula: [CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.sup.. Zn.sup.+ .sup.+].sub.w X wherein X is an anion which does not interfere with the effective increasing of absorption, distribution and utilization of zinc and methionine within the body system, and w is an integer equal to the anionic charge of X.
Claim 3
Dependent Claim
13 words

Claim 5
Dependent Claim
80 words
A dietary animal feed supplement composition comprising a food material and as a dietary supplement of zinc and methionine, complexed salts of the formula: [CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.sup.. Zn.sup.+ .sup.+].sub.w X wherein X is an anion which does not interfere with the effective increasing of absorption, distribution and utilization of zinc and methionine within the body system and w is an integer equal the anionic charge of X, the amount of said complexed salt being a diet supplementing effective amount.
Claim 6
Dependent Claim
80 words
A dietary animal feed supplement composition comprising a food material and as a dietary supplement of zinc and methionine, complexed salts of the formula: [CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.sup.. Zn.sup.+ .sup.+].sub.w X wherein X is an anion which does not interfere with the effective increasing of absorption, distribution and utilization of zinc and methionine within the body system and w is an integer equal the anionic charge of X, the amount of said complexed salt being a diet supplementing effective amount.
Claim 7
Dependent Claim
28 words
The dietary feed supplement composition of claim 4 wherein the amount of said complexed salt is from about 50 to about 500 grams per ton of food material.
