## Abstract

The invention relates to animal feeds and feed premixes containing synergistically effective amounts of betaine hydrochloride and a phytase.

## Claims

### Claim 1

An animal feed including:
a nutrient component including one or more of a carbohydrate, fat and protein;
a phytase; and
betaine hydrochloride (BHCl),
wherein the phytase and BHCl are provided in the feed in a ratio of
about 0.5 to 5 g BHCl per kg of feed:750 to 5000 phytase unit (FTU) per kg of feed; and wherein the ratio of BHCl:phytase provide for an energy utilization that is greater than the sum of the energy utilization in a feed that includes phytase only or BHCl only.

### Claim 2 (depends on 1)

The feed of claim 1, wherein the nutrient component of the feed has a starch content of not more than 270 g per kg of feed.

### Claim 3 (depends on 1)

The feed of claim 1, wherein the protein content of the feed is from 150 to 250 g per kg of feed.

### Claim 4 (depends on 1)

The feed of claim 1, wherein the fat content of the feed is not more than 45 g per kg of feed.

### Claim 5 (depends on 1)

The feed of claim 1, wherein the feed is a poultry feed.

### Claim 6 (depends on 1)

The animal feed of claim 1, wherein the phytase is of bacterial origin.

### Claim 7 (depends on 6)

The animal feed of claim 6, wherein the phytase has an amino acid sequence of an E. coli phytase.

### Claim 8 (depends on 1)

The animal feed of claim 1, wherein the BHCl and phytase are provided in a ratio of about 0.5 to 5 g BHCl per kg of feed:1000 to 3000 phytase unit (FTU) per kg of feed.

### Claim 9 (depends on 1)

The animal feed of claim 1, wherein the nutrient component does not include the following micronutrients as an additive or synthetic component: methionine, choline, lysine, threonine and inorganic phosphate.
