AMINO ACID ADDITIVE FOR ANIMAL FEED, METHOD FOR ITS PRODUCTION AND ANIMAL FEED OR PREMIX CONTAINING SAID ADDITIVE

摘要

PURPOSE: To obtain a low-cost animal feed additive by fermentation by incorporating at least one kind of amino acid at a high concn. in the case where excessive hygroscopicity or stickiness is not imparted, standardization is attained by an easy method and a by-product hardly causes hindrance. CONSTITUTION: This amino acid animal feed additive is based on a fermented liq. and contains not only an amino acid obtd. by fermentation but also the principal parts of the contents of the fermented liq. freed of at least a part of biomaterials or mechanically separable products. At least 40wt.% of the amino acid exists advantageously in the dry material of the fermented liq. The compsn. of the dry material consists of 40-90wt.% of the amino acid, =10wt.% protein, =8wt.% 8C carboxylic acid, =10wt.% total sugar, =5wt.% fat and oil and 3-30wt.% inorg. material.
