養魚用飼料に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fish feed additive that is effective for promoting the growth of farmed fish, improving feed efficiency, etc., and a fish feed prepared by adding the feed additive. It is something.
近年、経済成長に伴い国民の食生活の多様化、高級化指
向が進んだ結果、食用魚においても低級魚から高級魚へ
の需要移行が生し、そのため、天然魚の漁獲だけに依存
していたのでは側底需要に応じきれない魚が出てきた。In recent years, as a result of economic growth, people's dietary habits have become more diversified and people are becoming more sophisticated.As a result, there has been a shift in demand for edible fish from low-grade fish to high-grade fish, and as a result, there has been a shift in demand from low-grade fish to high-grade fish. Therefore, some fish were unable to meet the demand for the lateral bottom.
このような事情を背景に、食用魚類の増養殖は年々盛ん
になり、その量、魚種ともに著しく増加している。Against this background, the cultivation of edible fish is becoming more popular year by year, and both the amount and species of fish are increasing markedly.

溶媒である。Licorice hydrophobic flavonoids can be obtained by extracting licorice or its water-extracted residue with an organic solvent capable of extracting hydrophobic flavonoids under heating. Examples of extraction solvents that can be used include halogenated hydrocarbons such as methylene chloride and chloroform, lower alcohols such as methanol and ethanol, lower fatty acids such as acetone, and lower aliphatic ethers such as dioxane, ethyl ether, etc. , it
[There are lower aliphatic esters such as ethyl and n-propyl acetate, and in addition to these, there are also mixtures of 10 parts (by volume) hexane and 1 to 4 parts of acetone, and 10 parts of hexane and 0.5 to 0.5 to ethyl alcohol. A mixture such as 1.5 parts is a suitable extraction solvent.

The types and amounts of flavonoids among them vary slightly depending on the extraction raw material, extraction solvent, etc., but there is no major difference in effectiveness as feed additives for fish farming, and any of them can be used.

If it is dried and crushed into a powder, it can be easily mixed into feed and used. It may be dispersed in water using a food emulsifier such as a fatty acid ester or triglyceride to form a liquid or paste product.

I can do it. The amount of hydrophobic flavonoids added to the feed should be approximately 0.05 to 10% as flavonoids, taking into account the type of fish to which the feed is administered and the size of the fish.
It is desirable to select within the range of weight %.

殖コストの低減が達成される。Table 1: Breeding results (Note) Body weight: Average weight measured for 30 animals. Average body weight at the start of the test was 259.0±38.4g0 Daily feeding rate - (feeding amount) / (mid-term fed weight) x (breeding days or feeding days) mid-term fed weight = (total weight at start + total body weight at end) + Pick up weight) / 2 Numbers in parentheses are daily feeding rate weight gain rate per feeding days - (weight gain) / (total starting weight)
Weight gain - (Total weight at end + Weight taken up) - (Total weight at start) Feed efficiency - (Weight gain) / (Feeding amount) Meat gain coefficient - (Feeding amount) / (Weight gain) [Effects of the invention] Test As is clear from the results of the examples, according to the present invention, in which licorice extract containing hydrophobic flavonoids is added to feed and ingested by fish, it is possible to promote growth and improve feed efficiency in fish farming. As a result, the cultivation period and cultivation cost are reduced.
