Abstract

A method of improving milk yield in a ruminant animal a ruminant ration with an aqueous is presoaked with a solution of a composition of enzymes comprising a xylanase and a ferulic acid esterase.

First claim

We claim:

1 . A method of improving the digestibility of an equine or ruminant animal ration, comprising the step of treating the equine or ruminant ration by wetting with an aqueous solution of a composition of enzymes comprising a xylanase and a ferulic acid esterase, resulting in improvement of animal performance.

2 . The method of claim 1 , wherein the treated ration is allowed to remain in contact with the composition of enzymes for a residence period of time prior to being fed to the animal.

3 . The method of claim 1 , wherein the xylanase is present in the composition of enzymes in an amount between 5% and 95% and the ferulic acid esterase is present in the composition of enzymes in an amount between 1% and 20%.

4 . The method of claim 1 , wherein the ration comprises at least one component selected from the group consisting of soya forage, sugarcane bagasse, wheat straw, rice straw, green fodder, and a total mixed ration.

5 . The method of claim 1 , wherein the ration is soaked in the aqueous solution of a composition of enzymes and the animal is fed both the ration and any remaining aqueous solution.

6 . A method of reducing the NDF in an equine or ruminant animal ration, comprising the step of treating the ration by wetting with an aqueous solution of a composition of enzymes comprising a xylanase and a ferulic acid esterase.

7 . A method of increasing milk yield of a ruminant animal, comprising the step of treating a ruminant ration by wetting with an aqueous solution of a composition of enzymes comprising a xylanase and a ferulic acid esterase.

8 . The method of claim 7 , wherein the ruminant animal is a dairy animal in either the early lactation phase, the mid-lactation phase or the late lactation phase.

9 . The method of claim 1 , wherein the xylanase activity is between about 800,000 U/g and about 1520000 U/g and the ferulic acid esterase activity is between 4 U/g and about 80 U/g.

10 . A method of reducing the lignin content in an equine or ruminant animal ration, comprising the step of treating the ration by wetting with an aqueous solution of a composition of enzymes comprising a xylanase and a ferulic acid esterase.
