  • Patent number: 11235035
    Abstract: A method for improving the performance of a subject or for improving digestibility of a raw material in a feed (e.g. nutrient digestibility, such as amino acid digestibility), or for improving nitrogen retention, or for improving dietary phosphorus absorption and retention, or for improving the efficacy of the phytase, or for improving the subject's resistance to necrotic enteritis or for improving feed conversion ratio (FCR) or for improving weight gain in a subject or for improving feed efficiency in a subject or for modulating (e.g. improving) the immune response of the subject or for reducing populations of pathogenic bacteria in the gastrointestinal tract of a subject, or for reducing nutrient excretion in manure, which method comprising administering to a subject at least one direct fed microbial in combination with a phytase, wherein the phytase is administered to the subject at a dosage of more than about 1500 FTU/kg feed.

  • Publication number: 20150208693
    Abstract: A method of feeding is described. The method comprises feeding a mono-gastric animal with a feed, wherein said feed comprises a phytase, wherein said phytase results in an improvement in one or more of said animal's biophysical characteristics, especially when compared to the equivalent use of Peniophora lycii phytase and/or an E. coli phytase. In particular, the method results in an improvement in said animal's biophysical characteristics as a food source.
