(3) significantly improve cobio seedling liver liver, intestinal health, survival rate of fish fry significantly improves;
(4) raw materials used is convenient source, steady sources, cheap.
In order to the present invention can be understood more clearly, below the specific embodiment of the present invention will be elaborated.
Detailed description of the invention
Prepare cobio seedling open-mouthed bait according to following steps, concrete steps are:
S1, take each component according to following weight: steam fish meal 30kg, krill meal 3kg, crab meat 4kg, digested tankage 4kg, prosperous peptide albumen 3kg, fermentation cottonseed protein 6kg, bean dregs 8kg, peanut cake 8kg, squid viscera powder 7kg, beer yeast powder 3kg, wheat flour 9kg, sepiolite 2kg, fish oil 2kg, rapeseed oil 3kg, soybean lecithin 3kg, calcium dihydrogen phosphate 1.7kg, astaxanthin 0.3kg, premix 3kg;
S2, raw material (except fish oil, rapeseed oil and soybean lecithin) larger for particle in said components to be pulverized for the first time, first pulverize after raw material need by 50 mesh sieves;
S3, the component raw material after above-mentioned first pulverizing to be mixed in mixer, after mixed material is carried out ultramicro grinding, the mixed material after ultramicro grinding needed 70 mesh sieves, then added fish oil, rapeseed oil and soybean lecithin, again mixed;
S4, all materials mixed are carried out modified, granulate; Modified is carry out in quality controling machine, and pass into the steam of 85 DEG C, conditioning period is 7 minutes; Granulation carries out in granulator, and temperature is 90 DEG C, and feed particle diameter is 1.8mm;
S5, granulated meal is carried out drying, cooling, after carry out ultramicro grinding again, the feed after ultramicro grinding needed 60 mesh sieves, was finally packaged into bag.
A kind of cobio seedling open-mouthed bait provided by the invention, its basic point of departure is exactly to put the seedling initial stage to meet its nutrition and immune demand on the large pool of cobio seedling, considers that cobio natural bait in seedling stage is not enough, nutrition is balanced not, can provide the features such as the material of fry immunity is not enough in bait.Cobio seedling open-mouthed bait provided by the invention also contemplates protects the health of its liver and enteron aisle fry at growth and development stage; preferentially provide a series of active princlple; can effectively safeguard fry phase liver, intestinal health, improve fry immunity, ensure survival rate of fish fry.
Pass through culture experiment, result shows that cobio seedling open-mouthed bait of the present invention can meet whole nutritional needs of fry growth growth in cobio seedling growth process, the cobio seedling speed of growth improves more than 15%, growth cycle shortens 10 ~ 15d, fry immunity significantly improves, liver is clear, and enteron aisle is full, sturdy, and survival rate of fish fry improves 15 ~ 20%.Compared with common commercial feed, cobio seedling open-mouthed bait of the present invention is raw materials used is convenient source, steady sources, cheap.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, if these are changed and modification belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
