Abstract
Abstract Trace minerals when in contact with vitamin A in animal feed supplements and in animal feed have a deleterious effect upon vitamin A. This effect is reduced by treating trace minerals with lignin sulfonates before bringing the trace minerals into contact with vitamin A.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
89 words
An admixture of vitamin A and a trace mineral supplement containing at least one trace mineral wherein said supplement is composed of small, solid granular particles, the majority of said particles being of a size such that they pass through a 16 mesh screen, but essentially all are retained on an 80 mesh screen, each particle being an intimate mixture of: (a) at least one trace mineral coated with (b) an effective amount of lignin sulfonates to reduce degradation of vitamin A when in contact with said trace mineral.
Claim 2
Dependent Claim
89 words
An admixture of vitamin A and a trace mineral supplement containing at least one trace mineral wherein said supplement is composed of small, solid granular particles, the majority of said particles being of a size such that they pass through a 16 mesh screen, but essentially all are retained on an 80 mesh screen, each particle being an intimate mixture of: (a) at least one trace mineral coated with (b) an effective amount of lignin sulfonates to reduce degradation of vitamin A when in contact with said trace mineral.
Claim 3
Dependent Claim
41 words
The vitamin, trace mineral admixture of claim 1 wherein the particle size of said trace mineral supplement is such that the majority of said particles pass through a 16 mesh screen, but essentially all are retained on a 60 mesh screen.
Claim 4
Dependent Claim
45 words
The vitamin, trace mineral admixture of claim 1 wherein there is present in said supplement from about 2% by weight to about 25% by weight of lignin sulfonates and from about 98% by weight to about 75% by weight of at least one trace mineral.
Claim 5
Dependent Claim
30 words
The vitamin, trace mineral admixture of claim 3 wherein there is present in said supplement about 90% by weight of trace mineral and about 10% by weight of lignin sulfonates.
Claim 6
Dependent Claim
31 words
The vitamin, trace mineral admixture of claim 3 wherein said trace mineral is at least one selected from the group consisting of manganese, copper, iron, cobalt, iodine, zinc, selenium and magnesium.
Claim 7
Dependent Claim
18 words
The vitamin, trace mineral admixture of claim 3 wherein said vitamin A is present in a starch matrix.
Claim 8
Dependent Claim
16 words
The vitamin, trace mineral admixture of claim 6 wherein said vitamin A is vitamin A palmitate.
Claim 9
Dependent Claim
16 words
The vitamin, trace mineral mixture of claim 3 wherein said lignin sulfonates are calcimum lignin sulfonates.
Claim 10
Dependent Claim
16 words
The vitamin, trace mineral admixture of claim 3 wherein said lignin sulfonates are ammonium lignin sulfonates.
Claim 11
Dependent Claim
98 words
A process of stabilizing vitamin A in the presence of a trace mineral supplement containing at least one trace mineral comprising admixing vitamin A with said supplement which is composed of small, solid granular particles, the majority of said particles being of a size such that they pass through a 16 mesh screen, but essentially all are retained on an 80 mesh screen, each particle being an intimate mixture of: (a) at least one trace mineral coated with (b) an effective amount of lignin sulfonates to reduce degradation of vitamin A when in contact with said trace mineral.
Claim 12
Dependent Claim
98 words
A process of stabilizing vitamin A in the presence of a trace mineral supplement containing at least one trace mineral comprising admixing vitamin A with said supplement which is composed of small, solid granular particles, the majority of said particles being of a size such that they pass through a 16 mesh screen, but essentially all are retained on an 80 mesh screen, each particle being an intimate mixture of: (a) at least one trace mineral coated with (b) an effective amount of lignin sulfonates to reduce degradation of vitamin A when in contact with said trace mineral.
Claim 13
Dependent Claim
36 words
The process of claim 10 wherein the particle size of said supplement is such that the majority of said particles pass through a 16 mesh screen, but essentially all are retained on a 60 mesh screen.
Claim 14
Dependent Claim
42 words
The process of claim 10 wherein there is present in said supplement from about 2% by weight to about 25% by weight of lignin sulfonates and from about 98% by weight to about 75% by weight of at least one trace mineral.
Claim 15
Dependent Claim
27 words
The process of claim 12 wherein there is present in said supplement about 90% by weight of trace mineral and about 10% by weight of lignin sulfonates.
Claim 16
Dependent Claim
13 words
The process of claim 12 wherein said lignin sulfonates are calcium lignin sulfonates.
Claim 17
Dependent Claim
13 words
The process of claim 12 wherein said lignin sulfonates are ammonium lignin sulfonates.
Claim 18
Dependent Claim
28 words
The process of claim 12 wherein said trace mineral is at least one selected from the group consisting of manganese, copper, iron, cobalt, iodine, zinc, selenium and magnesium.
