  • FUSION OF BIOACTIVE MOLECULES
    Publication number: 20140356478
    Abstract: Fusion-proteins containing an enzyme, preferably a feed or food enzyme, coupled to a gut surface-binding domain are presented. The fusion-proteins can be used to promote feed utilization in animals. In a particular example, a Fusion enzyme according to the invention comprising a gut-surface-binding polypeptide segment linked to a phytase show an increased resident time in the gut, which leads to an increased amount of time given to the enzyme to catalyse the corresponding reaction which finally leads to improved feed utilisation.

  • Nitrooxy alkanoic acids and derivatives thereof in feed for reducing methane emission in ruminants, and/or to improve ruminant performance
    Patent number: 8784871
    Abstract: The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant and or for improving ruminant animal performance by using, as active compound at least one nitrooxy alkanoic acid and/or derivative thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these compounds in feed and feed additives such as premix, concentrates and total mixed ration (TMR) or in the form of a bolus.

  • USE OF NITROOXY ORGANIC MOLECULES IN FEED FOR REDUCING METHANE EMISSION IN RUMINANTS, AND/OR TO IMPROVE RUMINANT PERFORMANCE
    Publication number: 20140147529
    Abstract: The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant and/or for improving ruminant animal performance by using, as active compound at least one organic molecule substituted at any position with at least one nitrooxy group, or a salt thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these compounds in feed and feed additives such as premix, concentrates and total mixed ration (TMR) or in the form of a bolus.

  • USE OF A FEED COMPOSITION FOR REDUCING METHANE EMISSION IN RUMINANTS, AND/OR TO IMPROVE RUMINANT PERFORMANCE
    Publication number: 20140088161
    Abstract: The present invention relates to the field of reduction of methane emission in ruminants. Particularly, it relates to the use of a feed composition or a feed additive comprising at least one antibiotic and at least one organic molecule substituted at any position with at least one nitrooxy group for reducing the production of methane emanating from the digestive activities of ruminants, and/or to improve the ruminant performance.
