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.
Claims16
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.
