Abstract: A feed additive composition includes a protective agent, lecithin in an amount of 0.05 to 6% by weight relative to a total weight of the composition, a basic amino acid in an amount of at least 40% by weight and less than 65% by weight relative to the total weight of the composition, and water. A method of producing a feed additive composition includes preparing a molten mixture of at least one protective agent, lecithin and at least one basic amino acid, and solidifying the molten mixture by immersing the molten mixture in water or an aqueous liquid. The protective agent includes hydrogenated vegetable oils and/or hydrogenated animal oils having melting points of greater than 50° C. and less than 90° C.

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.

A method of preventing infectious diseases wherein cystine and the like and theanine are administered in combination, a method of enhancing an infectious disease-preventive action of cystine and the like, which contains administering cystine and the like and theanine in combination, a pharmaceutical composition, food and feed wherein cystine and the like and theanine are combined.

Abstract: A food additive composition for ruminants of the dispersion type and a method of continuously producing the same. This food additive composition for ruminants, which contains 40% by weight or more but less than 65% by weight of a basic amino acid and has rumen bypass properties, is formulated into granules in an arbitrary shape which are scarcely classified when added to a silage or another feed. Thus, attempts have been made to develop a method of producing granules by which the milk yield of a lactation cow can be increased. Namely, it is intended to provide a food additive composition for ruminants which contains at least one protecting agent selected from among a hardened vegetable oil and a hardened animal oil having a melting point higher than 50° C. but lower than 90° C., 0.05 to 6% by weight of lecithin, water and 40% by weight or more but less than 65% by weight of a basic amino acid.

Abstract: Administration of cystine or a salt thereof and theanine or a salt thereof is effective for retarding the progress of aging and reducing the effects of aging.

Abstract: Compounds which have an agonist action on a glycine receptor and compounds capable of being present as glycine in living organisms are effective for the prophylaxis or treatment of snoring or respiratory disorders during sleep. Foods and diets which contain such a compound are also effective for the prophylaxis or palliation of snoring or respiratory disorders during sleep.

Abstract: Effective preventive method for infectious diseases, an enhancing method of an infectious disease-preventive action of cysteine and composition, food and feed effective for infectious diseases are provided. A method of preventing infectious diseases wherein cystine and the like and theanine are administered in combination, a method of enhancing an infectious disease-preventive action of cystine and the like, which contains administering cystine and the like and theanine in combination, a pharmaceutical composition, food and feed wherein cystine and the like and theanine are combined.

Abstract: A method for preventing decrease of a breast milk amount in a mammal, which comprises administering glutamine to the mammal.

Abstract: A composition comprising modified milk powder, and glutamine and/or a peptide containing glutamine.

Abstract: The invention relates to biologically active substances coated with a coating composition containing at least one substance selected from the group consisting of hardened vegetable fats and oils, hardened animal fats and oils, fatty acid esters and phospholipids and an enzyme and/or enzyme activator where the outermost surface portion of the coating layer contains substantially no enzyme and/or enzyme activator. The invention materials exhibit excellent protection in the rumen of ruminant animals and allow for the dissolution in the post-abomasum lower digestive organs of the ruminant.

Abstract: A granular additive composition for ruminant feed which stably protects a biologically active substance in the rumen of the ruminant and allows it to be effectively digested and absorbed in the digestive organs after the abomasum.

Abstract: There is disclosed a compound having a double chain which is composed of an RNA (+chain) and a complementary DNA (-chain), wherein a portion of the DNA (-chain) has been replaced by an RNA or a derivative thereof, and wherein, when the compound is subjected to the action of an enzyme having a ribonuclease H activity, it is possible to preferentially cleave the RNA (+chain) in a position corresponding to the unsubstituted portion of the DNA (-chain). The compound can thus be used for the preferential cleavage of a phosphodiester bond in a specific position of RNA. Accordingly, the invention provides a useful means for preparing, for instance, a deletion mutant. There is also disclosed a mixed oligomer which comprises an oligomer of RNA or a derivative thereof and a DNA oligomer, wherein the RNA oligomer or a derivative thereof is conjugated to the DNA oligomer via a phosphate diester linkage between the 5'-hydroxyl group and the 3'-hydroxyl group in the ribose or deoxyribose moiety.
