Claims15
A method for improving poultry performance on one or more metrics selected from the group consisting of increased feed efficiency, increased weight gain, reduced feed conversion ratio, improved digestibility of nutrients or energy in a feed, improved nitrogen retention, improved ability to avoid the negative effects of necrotic enteritis, and improved immune response comprising administering an effective amount of a starter, grower, or finisher diet comprising (i) an engineered phytase polypeptide or a fragment thereof comprising phytase activity comprising at least 82% sequence identity with the amino acid sequence set forth in SEQ ID NO:1;
- and (ii) no inorganic phosphorus to poultry,
- wherein improved poultry performance is assessed by comparing to performance in poultry that are administered a starter, grower, or finisher diet that does not comprise (i) the engineered phytase polypeptide or a fragment thereof comprising phytase activity comprising at least 82% sequence identity with the amino acid sequence set forth in SEQ ID NO:1;
- and (ii) inorganic phosphate.
