ABSTRACT:

TECHNICAL FIELD
The present invention relates to a method for breeding an organism and a feed.
BACKGROUND ART
Recently, culture of useful organisms such as domestic animals, laboratory animals, domestic fowls, fishes and shrimps have remarkably become popular. On the other hand, occurrence of various diseases, underdevelopment and the like caused by stress due to a breeding environment such as packed breeding have become problems.
OBJECTS OF INVENTION
The main object of the present invention is to provide a method for breeding an organism and a feed useful for preventing or treating diseases of useful organisms such as cultured animals and for maintaining the health of the useful organisms.
SUMMARY OF INVENTION
The present invention is outlined as follows. The first invention of the present invention relates to a method for breeding an organism, characterized in that the method comprises administering:
(1) a heat treatment product of at least one compound selected from the group consisting of (a) uronic acid or a uronic acid derivative; (b) a saccharide containing uronic acid and/or a uronic acid derivative; and (c) a material containing a saccharide containing uronic acid and/or a uronic acid derivative;
(2) 4,5-dihydroxy-2-cyclopenten-1-one of formula (I):
 and/or
(3) a derivative of 4,5-dihydroxy-2-cyclopenten-1-one of formula (I), to an organism.
The second invention of the present invention relates to a feed for an organism which contains, which is produced by adding thereto, and/or which is produced by diluting a heat treatment product of at least one compound selected from the group consisting of (a), (b) and (c) as described above; 4,5-dihydroxy-2-cyclopenten-1-one of formula (I); and/or a derivative of 4,5-dihydroxy-2-cyclopenten-1-one of formula (I).
The third invention of the present invention relates to a composition for breeding an organism which contains a heat treatment product of at least one compound selected from the group consisting of (a), (b) and (c) as described above; 4,5-dihydroxy-2-cyclopenten-1-one of formula (I); and/or a derivative of 4,5-dihydroxy-2-cyclopenten-1-one of formula (I).
In the first to third inventions of the present invention, the organism is, for example, a cultured animal or a pet animal. The cultured organism is exemplified by a domestic animal, a laboratory animal, a domestic fowl, a fish, a crustacean and a shellfish. The heat treatment product is exemplified by a material containing 4,5-dihydroxy-2-cyclopenten-1-one of formula (I).
The feed of the second invention of the present invention is exemplified by a feed for improving physical condition.
The composition for breeding an organism of the third invention of the present invention is exemplified by a composition for soaking an organism, an additive for a feed, and an additive for a drink.
DETAILED DESCRIPTION OF THE INVENTION
As used herein, a heat treatment product of at least one compound selected from the group consisting of uronic acid or a uronic acid derivatives a saccharide containing uronic acid and/or a uronic acid derivative; and a material containing a saccharide containing uronic acid and/or a uronic acid derivative is not limited to a specific one as long as it has an effect of increasing efficiency of breeding an organism such as viability, fattening rate, spawning rate, birthrate or weaning rate.
Uronic acid is (also called as glycuronic acid) a generic name for hydroxyaldehyde-acids in which the aldehyde group of aldose is kept intact and only the primary alcohol group at the other end is oxidized into a carboxyl group. Uronic acid naturally exists as constituents of various polysaccharides in animals and plants.
Examples of uronic acids which can be used in the present invention include, but are not limited to, galacturonic acid, glucuronic acid, gluronic acid, mannuronic acid and iduronic acid. Derivatives of uronic acid include lactones, esters, amides and salts thereof.
As used herein, examples of saccharides containing uronic acid and/or a uronic acid derivative include, but are not limited to, pectin, pectic acid, alginic acid, hyaluronic acid, heparin, heparan sulfate, fucoidan, chondroitin sulfate, chondroitin and dermatan sulfate. Decomposition products (products of chemical, enzymatic or physical treatment) of the above-mentioned saccharides as well as derivatives and salts of the decomposition products can also be used.
As used herein, a material containing a saccharide containing uronic acid and/or a uronic acid derivative is not limited to a specific one as long as the material contains the above-mentioned saccharide containing uronic acid and/or a uronic acid derivative. Materials containing a saccharide containing uronic acid and/or a uronic acid derivative derived from plants, algae, microorganisms and animals can be used.
Alternatively, a processed agricultural or marine food product containing uronic acid and/or a uronic acid derivative may be used directly or after drying and grinding as a raw material for the heat treatment product in the present invention.
A method used for the heat treatment in the production of the heat treatment product of the present invention is not limited to a specific one as long as it produces a heat treatment product having physiological activities such as an activity of increasing breeding efficiency and an activity of improving physical condition. At least one compound selected from the group consisting of uronic acid or a uronic acid derivative; a saccharide containing uronic acid and/or a uronic acid derivative; and a material containing a saccharide containing uronic acid and/or a uronic acid derivative may be heated, for example, at 60-350° C. for a few seconds to a few days, preferably at 80-150° C. for a few minutes to a few days. A heat treatment product used in the present invention can be obtained by heating pectin or alginic acid, for example, at 80-150° C. for a few minutes to a few days. Furthermore, a heat treatment product of interest can be obtained by heating uronic acid, a lactone of uronic acid or a uronic acid ester at 60-150° C. for a few minutes to a few days.
Either wet heating or dry heating may be used for the heat treatment in the present invention. Among these, wet heating is preferable in view of production efficiency of a compound contained in the heat treatment product of the present invention having physiological activities such as an activity of increasing breeding efficiency and an activity of improving physical condition, for example, 4,5-dihydroxy-2-cyclopenten-1-one of formula (I) (hereinafter simply referred to as cyclopentenone). Any wet heating such as steam heating, pressurized steam heating and pressurized heating can be used. Direct heating using dry hot wind and indirect heating through a division wall from a heat source can be used as dry heating. Direct heating is exemplified by air current dry heating and spray dry heating. Drum dry heating and the like can be used as indirect heating.
Any methods may be used for producing cyclopentenone of the present invention. Cyclopentenone may be synthesized according to a chemical synthesis method [Carbohydrate Res., 247:217-222 (1993); Helvetica Chimica Acta, 55:2838-2844 (1972)]. Cyclopentenone produced in a heat treatment product of at least one compound selected from the group consisting of uronic acid or a uronic acid derivative; a saccharide containing uronic acid and/or a uronic acid derivative; and a material containing a saccharide containing uronic acid and/or a uronic acid derivative, or a product purified therefrom can be used. These heat treatment products containing cyclopentenone as well as products partially purified or purified therefrom can be used in the present invention (WO 98/13328).
A method used for the heat treatment in the production of the heat treatment product containing cyclopentenone of the present invention is not limited to a specific one as long as it produces cyclopentenone. Uronic acid or a uronic acid derivative; a saccharide containing uronic acid and/or a uronic acid deriv
