Compositions comprising polypeptides having xylanase activity and polypeptides having arabinofuranosidase activity for use in e.g. animal feed. Polypeptides having arabinofuranosidase activity polypeptides having xylanase activity and polynucleotides encoding the polypeptides. Nucleic acid constructs vectors and host cells comprising the polynucleotides as well as methods of producing and using the polypeptide.
