To sum up, at the Japanese croaker physilogical characteristics, the invention provides a kind of Japanese croaker mixed feed, protein content is 40-45% in its main constituent, and preferred protein content is 45%; Wherein, described protein source raw material is 63 mainly from fish meal and dregs of beans in the fish meal percentage by weight in the feed, and its 50-60% protein can be substituted by the protein of dregs of beans.
Further, the inventor has carried out " different amino acid patterns is to the influence of Japanese croaker (Nibea japonica) juvenile growth and body composition " test, prepare nitrogen such as 5 groups etc. can feed, No. 1 feed is a protein sources with fish meal and casein, organize in contrast, the 2-5 feed is a protein sources with carragheen, fish meal, casein and crystalline amino acid, simulate the full fish albumen of Japanese croaker juvenile fish (NLP) respectively, pagrosomus fish egg protein (REP), peru fish meal albumen (PFP) and soybean protein (SBP) amino acid compositional model.Result of the test shows, the growth and the control group of the full fish amino acid pattern of Japanese croaker feed do not have difference, it is desirable amino acid pattern, and the growth of dregs of beans amino acid pattern is relatively poor, with contrast and full fish amino acid pattern group significant difference is arranged all, wherein dregs of beans group methionine background values is 1.61% (very calculating), is lower than the content 2.90% (very calculating) of the methionine of full fish group.Therefore, methionine is first limiting amino acid in the dregs of beans.
For improving vegetable protein utilization ratio of raw materials in the feed, the inventor has carried out the test of " adding crystal amino acid; acidulant; chelating amino acid is to the influence of Japanese croaker juvenile growth and body composition ", to substitute the feed of 60% fish meal protein, amino acid pattern according to the full fish albumen of Japanese croaker juvenile fish (NLP), add citric acid respectively or add the amino acid pattern level of limiting amino acid (methionine and lysine) to full fish albumen (NLP), result of the test shows, the growth of adding the processed group of methionine or interpolation methionine and lysine is higher than other each groups significantly, illustrate that Japanese croaker can effectively utilize in the feed 56% soybean meal content, and feed efficiency does not have the difference of conspicuousness, no longer discharge phosphorus in the breeding process, the use amount of the inorganic iron MnZn copper mineral salt in feed of chelating amino acid whose use also minimizing the simultaneously to the external world.
Thus, in the preferred version provided by the invention mixed feed add percentage by weight<0.5 methionine,<0.5 methionine and<0.5 lysine composition or<0.5 methionine chelate salt, it is more reasonable that amino acid is formed, and more helps improving feed protein efficient.In addition, the inventor finds that after interpolation methionine, methionine-lysine or the methionine chelate salt, the amount that substitutes fish meal protein 60% with dregs of beans albumen suits, and can further reduce the use amount of fish meal like this.
The inventor has also carried out the test of " the different sugar level is to the influence of Japanese croaker growth and body composition thereof in the feed ", the result shows, in 43% forage protein level, under 6.8% fat level, the diet carbohydrate content of 0-24% is formed the influence that does not cause conspicuousness to Japanese croaker growth and body, but higher levels of diet carbohydrate content (greater than 24%) causes the significant decline of growth, and causes the liver body than raising significantly.Hence one can see that, and reasonable is that its sugared content should be at 15-24% in the mixed feed provided by the invention.
In addition, the inventor knows that by test fat content should be at 4-10% in the mixed feed of the present invention.
Japanese croaker compound feed for young of the present invention can adopt the production technology of general granular mixed feed to prepare, and earlier the dry raw material is done pulverization process before mixing.
The present invention has following advantage:
The present invention is directed to the Japanese croaker digestive physiological characteristics, select the high feedstuff of bioavailability, can satisfy Japanese croaker and propagate whole nutritional needs under the condition artificially; Have the Japanese croaker of promotion and grow fast, improve the Japanese croaker digestibility, reduce excretas such as nitrogen, phosphorus, help advantages such as environmental protection.In addition, this mixed feed its raw material source is stable, with low cost, is fit to the intensive culture of Japanese croaker.
