## Abstract

This invention relates to techniques for improving the efficiency of feed conversion, growth and yield of meat from ruminant livestock. There is provided a method of improving the growth rate and modifying the carcass quality of ruminant livestock. The method includes simultaneously feeding to the animal a protected protein meal and, in addition, a protected lipid in amounts which synergistically improve the growth rate and modify the carcass quality.

## Claims

### Claim 1

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal, which comprises simultaneously feeding to the animal protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality.

### Claim 2 (depends on 1)

A method of claim 1, wherein the protected protein meal is derived from an oil seed.

### Claim 3 (depends on 1)

A method according to claim 1, wherein the protected lipid is derived from an oil seed or animal lipid.

### Claim 4 (depends on 1)

A method according to claim 1, wherein between about 50 to about 70% of the protected protein meal is protected from degradation in the rumen of the animal.

### Claim 5 (depends on 1)

A method according to claim 1, wherein between about 65 to about 90% of the protected lipid is protected from degradation in the rumen of the animal.

### Claim 6 (depends on 1)

A method according to claim 1, wherein between about 75 to about 90% of the protected lipid is protected from degradation in the rumen of the animal.

### Claim 7 (depends on 1)

A method according to claim 1, wherein the ratio of protected protein meal to protected lipid varies with the stage of growth of the animal.

### Claim 8

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal, which comprises simultaneously feeding to the animal protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality, wherein the ratio of protected protein meal to protected lipid is substantially the same as the ratio of carcass protein to fat of the animal.

### Claim 9

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal, which comprises simultaneously feeding to the animal protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality, wherein the ratio of protected protein meal to protected lipid is between from about 3:1 protein to lipid to about 1:1.

### Claim 10

A synergistic composition for improving the growth rate and modifying the carcass quality of a ruminant livestock animal which comprises protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality.

### Claim 11

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal comprising simultaneously feeding to the animal a feed comprising by weight 15% protected sunflower seed meal and 10% to 15% protected canola oil seed.

### Claim 12

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal comprising simultaneously feeding to the animal a feed comprising grain, 15% protected sunflower seed meal by weight and 10% protected cotton seed lipid by weight.

### Claim 13 (depends on 12)

The method of claim 12, wherein the grain is barley.

### Claim 14 (depends on 12)

The method of claim 12, wherein the grain is oats.

### Claim 15

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal comprising simultaneously feeding to the animal a feed comprising grain, an ionophore, 15% protected sunflower seed meal by weight and 10% protected cotton seed lipid by weight.

### Claim 16 (depends on 15)

The method of claim 15, wherein the ionophore is monoensin.

### Claim 17 (depends on 15)

The method of claim 15, wherein the grain is barley.

### Claim 18 (depends on 15)

The method of claim 15, wherein the grain is oats.
