## Abstract

There is disclosed a method useful for applying feed supplements to feed, comprising: preparing an aqueous composition containing a metal-amino acid complex, such as zinc methionine, and directly applying the aqueous composition to the feed at a local manufacturing or feeding site. The method may further comprise transporting the aqueous composition to a feeding site after being prepared and before being applied onto the feed.

## Claims

### Claim 1

A method for applying feed supplements to feed, comprising: preparing an aqueous composition containing a metal-amino acid complex and applying the aqueous composition to the feed at a local site wherein the method does not include the step of applying said aqueous composition onto a carrier, thereby eliminating the steps of drying a carrier and packaging a carrier before transporting the aqueous composition to the local site.

### Claim 2 (depends on 1)

The method of claim 1 wherein the aqueous composition contains less than about 60 weight percent of the metal-amino acid complex.

### Claim 3 (depends on 1)

The method of claim 1 wherein the metal of the metal-amino acid complex is zinc, cobalt, manganese, chromium, copper or selenium.

### Claim 4 (depends on 3)

The method of claim 3 wherein the amino acid is an alpha amino acid or a beta amino acid.

### Claim 5 (depends on 1)

The method of claim 1 wherein the metal-amino acid complex is zinc methionine.

### Claim 6 (depends on 1)

The method of claim 1 wherein the metal-amino acid complex is a zinc-amino acid complex.

### Claim 7 (depends on 1)

The method of claim 1 further comprising transporting the aqueous composition to a local site after being prepared and before being applied onto the feed.

### Claim 8 (depends on 1)

The method of claim 1 wherein the aqueous composition is applied to the feed by spraying.

### Claim 9

A method for directly applying feed supplements to livestock feed at a local site, comprising: preparing an aqueous composition containing zinc methionine; transporting the aqueous composition to the site after being prepared and before being applied onto the feed; and directly applying the aqueous composition to the feed at the local site.
