## Abstract

The invention relates to utilising red marine macroalgae to provide improvements in growth performance.

## Claims

### Claim 1

A method for improving the growth performance of a ruminant livestock animal in a farming system including:
providing a red marine macroalgae to a farming system to enable consumption of the red marine macroalgae by a ruminant livestock animal in the farming system;
thereby improving the growth performance of the livestock animal in the system,
wherein the red marine macroalgae is prepared by adding the red marine macroalgae to a natural base or raw material and/or additive, or wherein the red marine macroalgae is prepared by a method of preparing a ruminant animal feed supplement comprising the step of adding the red marine macroalgae to an excipient; and
wherein the red marine macroalgae is an Asparagopsis species.

### Claim 2 (depends on 1)

A method according to claim 1, wherein a liquid, solid or semi-solid animal feed supplement is prepared from the red marine macroalgae added to a natural base, raw material, additive, and/or excipient.

### Claim 3 (depends on 1)

The method of claim 1, wherein the farming system is a pasture farming system.

### Claim 4 (depends on 1)

The method of claim 1, wherein the farming system is a cultivated pasture farming system.

### Claim 5 (depends on 1)

The method of claim 1, wherein the farming system is a stocker operation.

### Claim 6 (depends on 1)

The method of claim 1, wherein the farming system is a feedlot system.

### Claim 7 (depends on 1)

The method of claim 1, wherein the macroalgae is provided in the form of a lick stone or lick block.

### Claim 8 (depends on 1)

The method of claim 1, wherein the macroalgae is provided in the form of a feed for use in a pasture or feedlot system.

### Claim 9 (depends on 1)

The method of claim 1, wherein the red marine macroalgae is provided to the animal at 10 to 30 g/day.

### Claim 10 (depends on 1)

The method of claim 1, wherein the method improves feed conversion ratio or animal growth rate.
