Abstract: This invention relates to dietary supplement compositions, foodstuffs (e.g., animal feed) comprising the same and methods of utilizing the same. In particular, the invention provides ruminant dietary supplement compositions (e.g., comprising a protein extract (e.g., a crude protein extract (e.g., a bacterial or yeast extract))) having a specific nitrogen and/or amino acid profile and a small particle size, methods of manufacturing the same, and compositions containing and methods of using the same (e.g., as a liquid or dry dietary supplement composition or as a component of a foodstuff (e.g., animal feed) to increase ruminant protein and amino acid absorption).

Abstract: Methods and enzyme supplements for enhancing fiber digestion in mammals and birds are described. The supplement comprises an effective amount of acetyl esterase, formulated for feeding to animals consuming significant percentages of forages in the diet. The compositions of this invention improve dry matter and neutral detergent fiber disappearance rates, and are useful dietary supplements for improving fiber digestion. The compositions of this invention may be utilized alone or in combination with known exogenous fibrolytic enzyme supplement to improve fiber digestion in mammals and birds. The acetyl esterase advantageously used in the compositions and methods of the present invention is produced by a ruminal isolate of Orpinomyces.
