The present invention relates to animal feed or animal feed additives comprising polypeptides having protease activity and uses thereof. Specifically, the proteases are serine S1 proteases from Janibacter, Terracoccus and Knoellia, all belonging to the family Intrasporangiaceae of the suborder Micrococcineae. The proteases have a high activity at a broad pH-range (pH 3-7) and are thus highly active during the entire passage through the digestive tract. It also relates to the methods for producing the proteases and for using the proteases to improve animal performance and the nutritional value of animal feed.

Provided is a method for producing hen's egg improved in quality includes feeding a solid-cultured product of filamentous bacteria blended with feedstuff of a hen or the solid-cultured product of the filamentous bacteria alone to a hen to improve quality of the hen's egg, in which at least one quality among improvement in yolk color, improvement in eggshell strength, increase in an egg white height, increase in an eggshell thickness, increase in an egg weight, increase in a Haugh unit, increase in an egg production ratio, and reduction in a generation ratio of an abnormal egg is improved for hen's egg that the hen ingesting the solid-cultured product of the filamentous bacteria produce.

The present invention relates to a method of improving litter quality and/or reducing footpad dermatitis of a monogastric animal comprising administering to the animal a composition, an animal feed or an animal feed additive comprising one or more microbial muramidases.

The present invention relates to a method of improving litter quality and/or reducing footpad dermatitis of a monogastric animal comprising administering to the animal a composition, an animal feed or an animal feed additive comprising one or more microbial muramidases.

The present invention relates to a method of improving flock uniformity and/or meat quality of a monogastric animal comprising administering to the animal a composition, an animal feed or an animal feed additive comprising one or more microbial muramidases.

The present invention relates to a method of improving flock uniformity and/or meat quality of a monogastric animal comprising administering to the animal a composition, an animal feed or an animal feed additive comprising one or more microbial muramidases.

The present invention relates to pelletized feed compositions comprising granules which comprise an inner salt layer and an outer hydrophobic layer. The invention further relates to the use of salt and hydrophobic coated granules for steam treated pelletized feed compositions.
