Method of feeding young monogastric mammals and composition fed to young monogastric mammals

1. A method of feeding a healthy non-human monogastric mammal, the method comprising:

orally feeding the healthy non-human monogastric mammal a fluid animal feed during a pre-weaning period, the fluid animal feed comprising a fluid milk replacer, a supplemental feed material, an optional suspension agent, and optionally one or more antibiotics, wherein the supplemental feed material comprises at least about 50 weight percent hemicellulose, based on the dry weight of the supplemental feed material,

wherein the fluid animal feed is free of sugar alcohol.

2. The method of claim 1 wherein the healthy monogastric mammal is a piglet.

3. The method of claim 1 wherein the healthy monogastric mammal consumes at least about 500 milligrams of the supplemental feed material per kilogram of the healthy monogastric mammal per day.

4. The method of claim 1 wherein the healthy monogastric mammal consumes about 1000 milligrams, or less, of the supplemental feed material per kilogram of the healthy monogastric mammal per day.

5. The method of claim 1 wherein the healthy monogastric mammal is a piglet and exhibits at least about a 230 percent increase in weight during a two week long segment occurring during the pre-weaning period between about two days after birth to about seventeen days after birth; and wherein the supplemental feed is in an amount of at least about 1.1 weight percent based on the dry weight of the fluid animal feed.

6. The method of claim 1 wherein:

the healthy monogastric mammal is a first piglet,

the method is effective to allow the first piglet to gain at least about ten percent more weight during a one week long segment of the pre-weaning period as compared to the weight gain of a second piglet during the one week long segment;

wherein the supplemental feed is in an amount of at least about 0.25 weight percent based on the dry weight of the fluid animal feed; and

feed provided to the second piglet being free of the supplemental feed material the second piglet consuming the same fluid animal feed during the pre-weaning period as the first piglet consumes during the pre-weaning period.

7. The method of claim 1 wherein:

the healthy monogastric mammal is a first piglet,

the method is effective to allow the first piglet to consume at least about eight percent more of the fluid animal feed, based on the dry weight of the fluid animal feed, during a one week long segment of the pre-weaning period as compared to the dry basis amount of the fluid animal feed a second piglet consumes during the one week long segment;

wherein the supplemental feed is in an amount of at least about 0.25 weight percent based on the dry weight of the fluid animal feed; and

feed provided to the second piglet being free of the supplemental feed material, the second piglet consuming the same fluid animal feed during the pre-weaning period as the first piglet consumes during the pre-weaning period.

8. The method of claim 2 wherein the piglet weighs less than 30 pounds when receiving the supplemental feed composition.

9. The method of claim 1 wherein the healthy monogastric mammal is an equine animal.

10. The method of claim 1 wherein the supplemental feed material is present in an amount from about 0.25 weight percent to about 5 weight percent based on the dry weight of the fluid animal feed.

11. The method of claim 1 wherein the supplemental feed material is present in an amount from about 0.5 weight percent to about 2.5 weight percent based on the dry weight of the fluid animal feed.

12. The method of claim 2 wherein the feeding is ad libitum.

13. The method of claim 1 wherein the supplemental feed material is in the form of a powder such that at least about 90 wt % of the supplemental feed material passes through a 100 mesh screen.

14. The method of claim 1 where the total concentration of all hemicellulose sources in the supplemental feed material is at least about 80 wt % based on the total dry weight of the supplemental feed material.

15. The method of claim 1 wherein the source of the hemicellulose comprises psyllium.
