Abstract: A food composition that is useful for increasing antioxidant levels in the body is provided having increased levels of sulfur-containing amino acids, such as methionine, cysteine, or mixtures thereof. Methods of using these compositions for increasing antioxidant levels in the body in mammals, especially in companion animals, are also provided.

Abstract: Compositions and methods useful to promote bone development in a growing animal are disclosed.

Abstract: Compositions and methods for regulating gene expression in a growing animal are disclosed.

Abstract: Compositions and methods useful to enhance the development of the immune system of a growing animal are disclosed.

Abstract: Compositions are provided comprising a balance between lysine and essential amino acids and metabolizable energy. The compositions are useful in methods to prevent or treat obesity in an animal without concomitant loss of lean muscle mass. The compositions may also be used in methods to preserve or to cause a gain in lean muscle mass in an animal in need thereof.

Abstract: Compositions and methods useful to enhance neurologic development of a growing animal are disclosed.

Abstract: Methods for (1) evaluating feline kidney function by determining ghrelin level in feline tissue or biofluid and correlating the ghrelin level directly to kidney function and (2) diagnosing kidney disease in a feline comprises determining an observed ghrelin level in a tissue or biofluid of the feline and comparing the observed ghrelin level to a reference ghrelin level indicative of normal kidney function, wherein an observed level lower than the reference level is indicative of kidney disease or susceptibility thereto.

Abstract: Compositions useful to prevent or treat obesity in an animal are disclosed. The compositions comprise a capsaicinoid, preferably capsaicin, or an active metabolite thereof, in an amount effect to prevent or treat obesity in an animal. Also disclosed are methods to prevent or treat obesity in an animal comprising administering a composition of the present invention.

Abstract: This invention provides diets useful for promoting fat loss in animals having a total lysine to metabolizable energy ratio of from about 6 to about 10 g/Mcal. This invention also provides compositions for promoting fat loss in animals, methods for preparing the compositions, methods for using the diets and compositions, articles of manufacture comprising the diets and compositions, and means for communicating information or instructions about such diets, compositions, methods, and articles of manufacture.

Abstract: Compositions suitable for enhancing the antioxidant status of animals containing methionine, taurine, vitamin C, and vitamin E and methods for preparing and using such compositions to enhance the antioxidant status of animals.

Abstract: Methods for (1) evaluating feline kidney function by determining ghrelin level in feline tissue or biofluid and correlating the ghrelin level directly to kidney function and (2) diagnosing kidney disease in a feline comprises determining an observed ghrelin level in a tissue or biofluid of the feline and comparing the observed ghrelin level to a reference ghrelin level indicative of normal kidney function, wherein an observed level lower than the reference level is indicative of kidney disease or susceptibility thereto.

Abstract: A combination comprising two or more polynucleotides that are differentially expressed in fat animals compared to lean animals or two or more proteins produced by the expression of such polynucleotides is disclosed. The combination and probes based upon the combination are used for formulating a prognosis that an animal is likely to become fat, developing a diagnosis that an animal is fat, screening substances to determine if they are useful for modulating the amount of adipose tissue on an animal, and detecting the differential expression of one or more genes differentially expressed in fat animals compared to lean animals in a sample. Methods for using class predictor gene profiles to identify fat and lean animals are also disclosed.

Abstract: The invention provides compositions for preventing or treating inflammatory disease comprising one or more omega-3 fatty acids, one or more sulfur containing amino acids, and manganese and methods for preventing and treating inflammatory disease comprising administering such compositions to an animal susceptible to or suffering from inflammatory disease. In a preferred embodiment, the composition is admixed with one or more food ingredients to produce a food composition useful for preventing or treating inflammatory disease.

Abstract: Compositions for preventing or treating kidney disease comprising one or more food ingredients containing relatively low amounts of protein, sodium, and potassium, typically protein in amounts of from about 5% to about 40%, sodium in amounts of from about 0.01% to about 1%, and potassium in amounts of from about 0.01% to about 1%, and methods comprising administering such compositions to patients susceptible to or suffering from kidney disease for the purpose of preventing or treating kidney disease.

Abstract: Methods for (1) evaluating feline kidney function by determining ghrelin level in feline tissue or biofluid and correlating the ghrelin level directly to kidney function and (2) diagnosing kidney disease in a feline comprises determining an observed ghrelin level in a tissue or biofluid of the feline and comparing the observed ghrelin level to a reference ghrelin level indicative of normal kidney function, wherein an observed level lower than the reference level is indicative of kidney disease or susceptibility thereto.

Abstract: The invention encompasses methods for altering food intake, modifying nutrient digestibility and altering stool quality and/or stool frequency in an animal by adjusting the balance of metabolizable cations to metabolizable anions consumed by the animal.

Abstract: Methods for enhancing the quality of life of a senior or super senior animal by feeding the animal a composition comprising at least one omega-3 polyunsaturated fatty acid and various combinations of amino acids, minerals, and antioxidants in amounts effective to enhance alertness, improve vitality, protect cartilage, maintain muscle mass, enhance digestibility, and improve skin and pelage quality. Changes in expression of genes associated with several biological pathways induced in an animal by feeding it said composition are consistent with an enhanced quality of life.

Abstract: Methods for enhancing the palatability of compositions for consumption by an animal by adding a palatability enhancing amount of at least one methionine compound and optional inactive yeast to the compositions. The methionine compound, and optional yeast, is added to the compositions in an amount of at least about 0.01% by weight of the composition on a dry matter basis, generally in amounts of from about 0.01% to about 1.5% by weight of the composition. The compositions containing methionine compound, and optional yeast, are ingested more frequently and at a higher rate by animals, particularly finicky animals or older animals that tend not eat enough food to maintain their health.
