ISOLATED POLYPEPTIDE, INSULATED NUCLEIC ACID SEQUENCE, NUCLEIC ACID CONSTRUCTION, RECOMBINANT EXPRESSION VECTOR, RECOMBINANT BACCILLUS HOST, USE OF POLYPEPTID FOR A HIDDEN PRODUCT FOR METHOD FOR A THYDROID AIDDEN INTESTINAL ANIMAL MICROFLORA, ANIMAL FEED ADDITIVE, AND ANIMAL FEED COMPOSITION. The present invention relates to isolated polypeptides and isolated nucleic acid sequences encoding the polypeptides, as well as methods for producing and using the polypeptides in animal feed. An example of a polypeptide of the invention is the so-called Bacilius licheniformis ATCC 14580 protein L12 which improves feed conversion rate (FCR) and / or acts as an intestinal microflora modulator. The invention further relates to the probiotic use of Bacilius strains producing L12-related proteins.
