Abstract
The present invention discloses a process for improving the efficiency of feed utilization and/or for promoting the growth of animals in which an animal is fed a diet which comprises a composition comprising feed substance and a ready for use phospholipase additive. Preferably said composition also comprises at least one phospholipid. Said compositions are used to improve fat digestibility and to promote growth of the animal. The phospholipid is preferably lecithin and the preferred phospholipase is a mammalian phospholipase A2. In a preferred embodiment the phospholipase is produced using recombinant DNA technology to express the enzyme in a suitable host such as a microorganism or a transgenic plant.
Claims22
A process for improving the efficiency of a feed utilization in which an animal is fed a diet which comprises a composition comprising a feed substance and a ready-for-use phospholipase additive.
An animal feed composition comprising a feed substance for a monogastric or polygastric animal and a phospholipase additive, wherein said monogastric or polygastric animal feed composition is suitable for direct consumption, and said phospholipase additive is provided as phospholipase enzyme in an amount sufficient to enhance weight gain or feed efficiency.
A method to produce an animal feed composition for a monogastric or polygastric animal that comprises about 10 to 10,000 IU phospholipase per kg of feed and which is suitable for direct consumption, which method comprises mixing about 10 to 10,000 IU phospholipase per kg of feed substance.
A transgenic plant cell, plant part, or plant which is modified to be capable to produce a recombinant phospholipase.
A method to improve the efficiency of feed utilization in an animal, which method comprises feeding said animal a feed composition that comprises a feed substance for said animal and about 10 to 10,000 IU phospholipase per kg feed, wherein said phospholipase is provided as phospholipase enzyme included in said composition as an additive and wherein said animal is a calf.
A method for promoting the growth of a monogastric or polygastric animal which method comprises feeding said monogastric or polygastric animal a feed composition that comprises a feed substance for said animal and about 10 to 10,000 IU phospholipase per kg feed, wherein said phospholipase is provided as phospholipase enzyme included in said composition as an additive and wherein said animal is a calf.
