The present invention provides astrain selected from the group consisting of a) the strain deposited as DSM32324,b) the strain deposited as DSM32325, and c) a mutant strain of (a) or (b) which has sensitivity for ampicillin, vancomycin, gentamicin, kanamycin, streptomycin, erythromycin, clindamycin, tetracycline, and chloramphenicol; and has inhibitory activity againstand Clostridium perfringens. The invention further relates tocompositions comprising at least onestrain of the invention, preferably thestrain DSM32324 and/or thestrain DSM32325, as Direct Fed Microbial (DFM), premix, animal feed additive or animal feed. The invention provides a method of improving one or more animal performance parameters selected from the group consisting of i) increased weight gain (WG), ii) lower feed conversion ratio (FCR), iii) lower necrotic enteritis lesion scoring, iv) lower necrotic enteritis frequency, v) lower necrotic enteritis mortality, vi) increased European Production Efficacy Factor (EPEF), and vii) lower mortality, by feeding a strain or a composition according to the invention to an animal.

Methods are provided for assaying whether acomposition comprising at least onestrain is capable of increasing the amount of sugar available from animal feed comprising non-starch polysaccharides (NSP) in vivo when thecomposition and animal feed are fed to an animal. Methods also are provided for increasing the amount of sugar available from animal feed comprising non-starch polysaccharides (NSP) when the animal feed is fed to an animal, comprising adding to the animal feed acomposition comprising at least onestrain, wherein the composition produces 120 hexose equivalents (&#x3bc;mol/ml) or more when measured by the method described herein. Animal feeds comprising 14% (w/w) or more of non-starch polysaccharides (NSP) if the animal feed is for a piglet, lactating sow, broiler or layer, or 19% (w/w) or more of non-starch polysaccharides (NSP) if the animal feed is for a grower-finisher pig or gestating sow, and acomposition comprising at least onestrain, as well as methods and uses relating thereto, also are provided.
