Description

A kind of low meal compound feed of Epinephelus coioides

Technical field

The present invention relates to fish meal technical field is and in particular to a kind of low meal compound feed of Epinephelus coioides.

Background technology

Cabrilla is the important marine fish of China, and Grouper cultivating industry development is very rapid nearly ten years, cuts Only 2014, China's Mainland Grouper cultivating yield reached 8.813 ten thousand tons (China fisheries yearbooks in 2015), in marine fish culture The 4th is occupied in yield.But, fast-developing Grouper cultivating industry is serious with cabrilla artifical compound feed research and development of products Delayed and using there is obvious contrast between wretched insufficiency.Grouper cultivating still heavy dependence chilled trash fish at present, annual consumption About 400,000 tons of amount, accounts for the 10% of national aquaculture chilled trash fish consumption, and adopt mixed feed cultivate the ratio of cabrilla less than 10%.Main cause is that fisherman has using chilled trash fish cultivation cabrilla tradition, and the supply of chilled trash fish is relatively sufficient at present, Price is relatively low, and mixed feed is at aspects such as palatability, using effect, prices, and cost performance is not also high.Therefore, research and development are needed badly Cabrilla efficient compound feed.Additionally, the species that China cultivates cabrilla is many, and the nutritional physiology of each cultivation species is ground Study carefully also not enough, its nutritional need parameter is short of, and this makes the overall technology of grouper compound feed be in relatively to a great extent Low-level, is the major reason that mixed feed is difficult in adapt to cabrilla industrialized development.Set up fairly perfect main stone The nutritional need data base of speckle fish culture species, carries out fine nutrition regulation technology and feed processing technology exploitation, constantly researches and develops With promote the use of efficiently special grouper compound feed, change with chilled trash fish cultivate cabrilla traditional breeding way, realization Mixed feed uses full range, promotes health and the sustainable development of China's Grouper cultivating industry.

In recent years, people had carried out a large amount of exploration and practices to grouper compound feed it is proposed that various technology solves Scheme.

During preparation, by fish flour, casein, gelatin, fish oil, Oleum Glycines, soybean phospholipid, corn starch, dalcium biphosphate, compound dimension life Plain premix material, composite trace element premix, taurine, sodium alginate, choline chloride, zeolite powder, microcrystal cellulose powder are each former Material is through pulverizing, crossing 60 mesh sieves, mixing, pelletize, you can be configured to Epinephelus coioides mixed feed.

Epinephelus coioides mixed feed feeding experiment given below, process of the test is as follows:

Epinephelus coioides juvenile fish first passes through 15 days and temporarily supports, and adapts to after cultivating condition after it, then choose the close fish of specification divide at random It is fitted in 12 glass aquariums (150l) having circulating water device, every case puts fish 20 tail.Randomly select 3 aquariums as 1 Individual test process, the fish of each treatment group feeds a kind of test feed.Be satiated with food daily feed test fish twice (8:00 and 18: 00) collect surplus material with siphonage after, feeding half an hour every time, subsequently remove contamination, after removing contamination, supply row in case with fresh filtering sea The sea water falling.Culture experiment carries out 56d.Continue oxygen supplement, natural lighting with oxygen increasing pump during cultivation.Water temperature 27.5- during cultivation 31.8 DEG C, dissolved oxygen amount is maintained at more than 5.7mg/l, ph value 6.72-7.83.

Culture experiment measures the body weight of the Epinephelus coioides of DIFFERENT FEED of ingesting respectively after terminating, to calculate rate of body weight gain, to raise Material efficiency, daily feeding quantity.5 tail fishes are taken again successively at random from every case, respectively measurement body length and body weight after having claimed fish live body weight, then Fish is dissected, takes out liver and weigh, to calculate liver body index.Liver is used for measuring hepatic glycogen regulating liver-QI fat.Again from each water Race's case takes 5 tail fishes to merge into a full fish sample, for measuring fish body conventional ingredient at random.These parameters are used for evaluating difference joins Close the impact of feedstuff epinephelus coioides growth performance.

The Epinephelus coioides growth test of DIFFERENT FEED feeding the results are shown in Table 2.

As shown in Table 2, feedstuff DIFFERENT FEED does not affect Epinephelus coioides body composition.The hepatic glycogen content of feedstuff 2 and 4 groups of feedstuff is poor Different not notable, but apparently higher than feedstuff 1 and 3 groups of feedstuff, and the liver fat of feedstuff 1, feedstuff 2 and 4 groups of feedstuff is apparently higher than feedstuff 3 Group, this has substantial connection with content of starch in feedstuff.

This specific embodiment has carried out calorie-protein ratio optimization to feedstuff, balanced in nutrition, meets Epinephelus coioides energy With the needs of protein, raw materials used be easy to get, simple processing, there is wide market application foreground.

Ultimate principle and principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry , it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description is originally for personnel The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and its Equivalent thereof.
