Abstract

Isoflavone-supplemented milk replacers fed to young animals during a pre-weaning provides isoflavones in the milk replacer at a level of about 700 mg per kilogram of the milk replacer, and/or provides about 450 mg of the supplemental isoflavone in at least about 1.5 pounds of the milk replacer by dry weight such that the animal ingests this amount of the isoflavone per day, and/or provides in the milk replacer at least about 50 mg of isoflavone per pound of the animal's birth weight is ingested per day. In response to ingesting the isoflavone-supplemented milk replacer, the young animal experiences improved performance.

First claim

What is claimed is:

1. A method of feeding a piglet an isoflavone-supplemented milk replacer comprising:
providing a milk replacer to a piglet on a daily basis during at least two weeks of a pre-weaning phase in which the piglet ingests the milk replacer, the milk replacer comprising an isoflavone supplement added to the milk replacer, the isoflavone supplement providing a supplemental level of isoflavone comprising about 700 mg per kilogram of the milk replacer,
wherein in response to ingesting the isoflavone-supplemented milk replacer for one week to three weeks, the piglet experiences improved performance,
wherein the isoflavone supplement is a powdered isoflavone extract derived from soy,
wherein the powdered isoflavone extract comprises one or more soy-derived isoflavones isolated from one or more other soy-derived isoflavones excluded from the powdered isoflavone extract, wherein the one or more other soy-derived isoflavones excluded from the powdered isoflavone extract comprise glycitein.

2. The method of claim 1 , wherein the piglet is provided the milk replacer on the daily basis for about three weeks during the pre-weaning phase.

3. The method of claim 1 , wherein protein in the milk replacer is derived from all-milk proteins, non-milk proteins, or a combination.

4. The method of claim 3 , wherein a protein level in the milk replacer is at least about 18 percent by dry weight.

5. The method of claim 1 , wherein the improved performance experienced by the piglet is one or more of an improved weight gain, an improved average daily gain, an improved feed intake, or an improved feed to gain ratio.

6. The method of claim 1 , wherein the one or more soy-derived isoflavones of the powdered isoflavone extract comprise an aglycone form of isoflavone.

7. The method of claim 6 , wherein the aglycone form of isoflavone comprises genistein aglycone and the one or more other soy-derived isoflavones further comprise daidzein.
