Description
Technical field
The present invention relates to culture fishery, be specifically related to a kind of 1% aquatic products premixed feed and preparation method thereof.
Background technology
Be main transformation along with China's fish production structure is main by fishing operation to aquaculture, the importance of feed in aquaculture rises day by day.Research shows, affect in the factor of the ecosystem and aquatic products growth many, the nutrition of feed and quality are one of key factors, can say the high-quality mixed feed of comprehensive nutrition use and universal be the key mark of culture fishery technological progress.Good fish feed not only should meet the nutritional need of Aquatic farming animals, habit and feeding habits, and should high feed efficiency, low cost, should meet market and breeding ecological environment to the requirement of feed simultaneously.In recent years, aquaculture feed industry is in the ascendant, but still there is many problems.The cultivation of many aquatic species mainly relies on natural animal bait, causes that the cost of bait is high, efficiency is low and hygienic quality is poor, and easily causes Cultivated water to pollute.Compared with abroad, there is again the defects such as insufficient funds, equipment backwardness and research means imperfection in our aquatic feeds research.The high-quality mixed feed that China has intellectual property is of less types, and complete formula technique and industrialization engineering differ comparatively far away with production actual requirement, directly affect health and the sustainable development of mariculture industry.Use high-quality and efficient feed for improve cultured product quality, reduce costs, reduce disease, prevent the pollution of the environment, increasing economic efficiency etc. has decisive role.The nutritional requirement of system research primary cultivated species, the feed formula of design high-quality, Devoting Major Efforts To Developing and development quality is high, stability, attractant and absorbability are got well and contribute to improving immunologic function and anti-adversity ability, the environmental type feed that feed coefficient is low, strengthen the exploition and management of feed addictive, utilize new and high technology exploitation to have the additive of food calling, growth promotion, antibacterial disease-proof functions, will the important guarantee of aquatic product health cultivation sustainable development be become.
Chitooligosaccharide-is obtained by the product degradation of chitosan that chitin is deacetylated, and be also unique a large amount of basic amine group polysaccharide existed in natural sugar, good water solubility, directly absorbs by animal intestinal epithelial cell.Chitooligosaccharide-is applied to during aquatic products are produced to be had regulating intestinal canal Tiny ecosystem, promote aquatic products growths, develop immunitypty, improves the effects such as breeding water.Chitooligosaccharide-is used to have bright prospects as novel green feed addictive that is nontoxic, that have no side effect.
Summary of the invention
The object of the present invention is to provide a kind of high-quality and efficient, aquatic products premix feed of meeting aquaculture nutritional needs and ecological environment requirement and preparation method thereof.
For achieving the above object, the technical scheme taked of the present invention:
A kind of 1% aquatic products premix feed, the components by weight percent proportioning of described raw material is:
Wherein, described antioxidant a and antioxidant b is selected from two kinds in reduced glutathione, carotenoid, taurine.
Wherein, described chitooligosaccharide-is produced by dry shrimp shell and is obtained, and its preparation method is:
(1) dry shrimp shell is added the fragment of pure water pulverizing into about 4 × 4mm2 size, cross 50 mesh sieves, the shrimp shell after sieving loads 50 object nylon net bags, soak 20 hours in 9%NaOH solution under room temperature, filter, dry, be flushed to neutrality with clear water, then dry, complete alkali treatment and take off albumen operation; The fine powder obtained that wherein sieves can make concentrated feed, and the protein extracted by filtrate obtains as byproduct;
(2) edta edta is dissolved in NaOH solution, the saturated solution of obtained pH=7, alkali treatment in step (1) is taken off albumen operation shrimp shell immerse in EDTA saturated solution, immersion treatment 20 hours under room temperature, filters, and dries, completes decalcification operation;
(3) alkali treatment and EDTA process decalcification operation is repeated each once, wet feed adds 55%NaOH solution, about 55 DEG C process 16 hours, then filter, then with newly joining the reprocessing of 55%NaOH solution once, filter, clear water is washed till neutrality, dries, about 70 DEG C forced air dryings, obtain white shitosan finished product, deacetylation DD > 65%.
(4) shitosan of acquisition and 55 DEG C of glacial acetic acid solution are joined in the enzymatic vessel of 1000L dissolve;
(5) temperature is 60 DEG C, during pH=6.5, adds enzyme by 1ml enzyme liquid/15g shitosan, and insulated and stirred, the shitosan obtained in the first step after 8h is converted into chitooligosaccharide-solution;
(6) chitooligosaccharide-solution is dry, obtain aquatic products premix chitooligosaccharide-.
The present invention discloses a kind of preparation method of described 1% aquatic products premixed feed, it is characterized in that, comprise the steps:
(1) various raw material are pulverized, cross 80 mesh sieves, obtain powder-material;
(2) raw material of powdery are weighed by proportioning, mixing;
(3) by the powder-material of mixing by being steam heated to 70 ~ 90 DEG C, complete granulation;
(4) obtained particle is carried out cool, classification, packaging, obtain final products.
Prove through culture experiment, compared with the control group using the carp of premix of the present invention and use not to add the premix of chitooligosaccharide-, speed of production is obviously accelerated, and through test in 67 days, average every tail carp rate of body weight gain improved 14%; In breeding process, disease occurs relatively less; Owing to employing chitooligosaccharide-in premix, breeding environment improves, and the carp quality of cultivation is better, and efficiency of feed utilization is high, and fish body minerals and vitamins content is apparently higher than control group.
Beneficial effect:
The beneficial effect of 1% aquatic products premixed feed of the present invention is:
(1) 1% aquatic products premixed feed formula of the present invention is reasonable, stable in properties, and comprehensive nutrition, can meet the requirement of aquatic products g and D,
(2) 1% aquatic products premix feed of the present invention with the addition of chitooligosaccharide-especially; suppress pathogen; reduce generation that is poisonous and pathogenic metabolin; improve aquatic products immunity of organisms, nontoxic, have no side effect, the feed addictives such as substitute antibiotics; to solution medicament residue; protection of the environment and health, accelerate the foreign exchange earning of aquatic products, significant.
