## Abstract

The present invention provides methods for feeding older sows that beneficially reduce feed intake in older sows, yet improve pig survival and weaning weight of pigs from older sows.

## Claims

### Claim 1

A method to increase the survival rate of pigs produced by a parity 3 or greater sow while reducing the feed intake of the parity 3 or greater sow, comprising providing the parity 3 or greater sow a diet comprising an effective amount of plasma so that the survival rate of pigs produced by the sow is increased while the feed intake of the sow is reduced.

### Claim 2 (depends on 1)

The method of claim 1, wherein the amount of plasma is about 0.4-0.6% of the diet.

### Claim 3 (depends on 1)

The method of claim 1, wherein the amount of plasma is at least about 0.01% of the diet.

### Claim 4 (depends on 1)

The method of claim 1, wherein the amount of plasma is at least about 0.5% of the diet.

### Claim 5 (depends on 1)

The method of claim 1, wherein the amount of plasma is less than about 15% of the diet.

### Claim 6 (depends on 1)

The method of claim 1, wherein the plasma is from a bovine, porcine, or avian species.

### Claim 7 (depends on 1)

The method of claim 1, wherein the plasma is spray-dried.

### Claim 8 (depends on 1)

The method of claim 1, wherein the plasma has not been separated from whole blood.

### Claim 9 (depends on 1)

The method of claim 1, wherein the plasma has been separated from whole blood.

### Claim 10

A method to improve the survival rate of top-value pigs produced by a parity 3 or greater sow while reducing the feed intake of the parity 3 or greater sow, comprising providing the parity 3 or greater sow a diet comprising an effective amount of plasma so that the survival rate of top-value pigs produced by the sow is improved while the feed intake of the sow is reduced.

### Claim 11 (depends on 10)

The method of claim 10, wherein the amount of plasma is about 0.4-0.6% of the diet.

### Claim 12 (depends on 10)

The method of claim 10, wherein the amount of plasma is at least about 0.01% of the diet.

### Claim 13 (depends on 10)

The method of claim 10, wherein the amount of plasma is at least about 0.5% of the diet.

### Claim 14 (depends on 10)

The method of claim 10, wherein the amount of plasma is less than about 15% of the diet.

### Claim 15 (depends on 10)

The method of claim 10, wherein the plasma is from a bovine, porcine, or avian species.

### Claim 16 (depends on 10)

The method of claim 10, wherein the plasma is spray-dried.

### Claim 17 (depends on 10)

The method of claim 10, wherein the plasma has not been separated from whole blood.

### Claim 18 (depends on 10)

The method of claim 10, wherein the plasma has been separated from whole blood.
