Patent ID: 8399411

Claim:
A method for reducing mitogen-activated-protein kinase activity in an animal, wherein the method comprises feeding the animal a composition comprising: a fat content of from about 13% to about 20% by weight on a dry matter basis, a protein content of from about 55% to about 65% by weight on a dry matter basis, and a carbohydrate content of less than 11% by weight on a dry matter basis; wherein the weight ratio of the omega-6 polyunsaturated fatty acids to the omega-3 polyunsaturated fatty acids is from about 0.3:1 to about 5:1; wherein the omega-3 polyunsaturated fatty acids comprise fatty acids with less than 20 carbon atoms, and fatty acids with greater than 20 carbon atoms; and the omega-6 polyunsaturated fatty, acids comprise fatty acids with less than 20 carbon atoms, and fatty acids with greater than 20 carbon atoms; and the concentration of omega-3 polyunsaturated fatty acids with less than 20 carbon atoms is from about 0.9% to about 1.2% by weight of the composition on a dry matter basis; and the concentration of omega-3 polyunsaturated fatty acids with greater than 20 carbon atoms is from about 4.2% to about 6.0% by weight of the composition on a dry matter basis; and the concentration of omega-6 polyunsaturated fatty acids with less than 20 carbon atoms is from about 1.9% to about 4.8% by weight of the composition on a dry matter basis; and the concentration of omega-6 polyunsaturated fatty acids with greater than 20 carbon atoms is from about 1.0% to about 1.3% by weight of the composition on a dry matter basis; and wherein mitogen-activated-protein kinase activity is reduced in the animal.
