Abstract

A feed additive composition includes a protective agent, lecithin, an acidic or neutral amino acid, and water. A method of producing a feed additive composition includes preparing a molten mixture of a protective agent, lecithin, and an acidic or neutral amino acid, and immersing the molten mixture in water or an aqueous liquid to obtain a solidified mixture. Feed additives may be obtained by such method. The protective agent may include a hydrogenated vegetable oil or hydrogenated animal oil having a melting point of higher than 50° C. and lower than 90° C.

First claim

The invention claimed is:

1. A method of producing a feed additive composition, comprising:
preparing a molten mixture of at least one protective agent, lecithin, and an acidic or neutral amino acid; and
immersing the molten mixture in water or an aqueous liquid to obtain a solidified mixture;
wherein:
the at least one protective agent comprises at least one member selected from the group consisting of a hydrogenated vegetable oil having a melting point of higher than 50° C. and lower than 90° C. and a hydrogenated animal oil having a melting point higher than 50° C. and lower than 90° C.; and
the acidic or neutral amino acid is glutamic acid or glutamine.

2. The method according to claim 1 , wherein:
preparing the molten mixture comprises preparing the molten mixture by heating and melting with an extruder; and
immersing the molten mixture comprises placing the molten mixture in a multi-hole shooter comprising a vessel bottom including a plurality of holes, and allowing the molten mixture to fall through the plurality of holes into water or the aqueous liquid.

3. The method according to claim 2 , wherein a distance from the vessel bottom to the surface of the water or the aqueous liquid is from 5 to 50 cm.

4. The method according to claim 1 , further comprising heat-treating the solidified mixture.

5. The method according to claim 1 , wherein the at least one protective agent comprises at least one member selected from the group consisting of hydrogenated soybean oil, hydrogenated rapeseed oil, hydrogenated groundnut oil, hydrogenated olive oil, hydrogenated cottonseed oil, and hydrogenated palm oil.

6. The method according to claim 1 , wherein the acidic or neutral amino acid has an average particle size of 100 μm or less.

7. The method according to claim 1 , wherein preparing the molten mixture comprises adding lecithin in an amount such that lecithin is present in the feed additive composition in an amount of from 1 to 2% by weight.

8. The method according to claim 1 , wherein:
immersing the molten mixture in water comprises immersing in water in a tank that is being stirred and maintained at a constant temperature; and
the method further comprises discharging the solidified mixture from the tank with overflowing water.
