Abstract
The invention provides complex immunoenhancer for prawns. The complex immunoenhancer is prepared from, by weight, 5-10% of laminarin, 10-20% of astragalus polysaccharide, 20-30% of zymosan, 20-30% of chitosan, 5-10% of garlicin, 5-15% of vitamin C and 10-30% of wheat middling. The raw materials are ground through an ultrafine grinder, screened by a 100-mesh screen and then evenly mixed quantitatively according to the ratio, and the adding proportion of the complex immunoenhancer in fodder is 0.2-0.5%. The complex immunoenhancer can obviously enhance the immunity of the bred prawns, can promote the growth of the prawns and is free of toxins, harm and residues.
Description
Technical field
The present invention relates to technical field of aquaculture, particularly a kind of prawn composite immune reinforcing agent.
Background technology
In recent years, China's shrimp culture industry fast development, cultured area increases year by year, increasing culturist adopts intensive industrial aquaculture prawn, under this high-density breeding condition, and prawn fast growth, but prawn resistance significantly declines, resistance against diseases is poor, and external pathogen is easy to infect, and cultured prawn is fallen ill.But use antibiotic to treat morbidity prawn, can short-term prove effective, but thing followed negative effect is also apparent.Chemical reagent such as chlorine, the formalin etc. of low dosage is used not work to pathogeny, because will kill dosage needed for pathogen is also often fatal to prawn larvae.Therefore, how seeking one effectively can strengthen immunity of prawn, and the nontoxic immunopotentiator improving its premunition is emphasis of the present invention.Safe with it, efficient, nontoxic, the free of contamination advantage of polysaccharide, becomes the main component of animal immunity potentiator.
Summary of the invention
The present invention is that object is to provide a kind of prawn composite immune reinforcing agent, is added in feed aquiculture animal of feeding, can improves the anti-stress ability of cultivated animals, strengthens immunity of organisms, improves survival rate.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of prawn composite immune reinforcing agent, by weight percentage, be mixed by following component: laminarin 5-10%, astragalus polyose 10-20%, zymosan 20-30%, shitosan 20-30%, allicin 5-10%, vitamin C 5-15%, secondary powder 10-30%.
As preferably, the component of above-mentioned immunopotentiator is laminarin 7%, astragalus polyose 16%, zymosan 20%, shitosan 25%, allicin 5%, vitamin C 10%, secondary powder 17%.
Aquatic products immunopotentiator of the present invention, by accounting for mixed feed weighing scale, the addition of this immunopotentiator in mixed feed is 0.2-1.5%.
Prawn of the present invention composite immune reinforcing agent effectively enhances the immunity of animal body, and has obvious anti-bacteria and anti-virus effect.And, there is food calling effect, promote growth of animal.The each component safety of this immunopotentiator, has no side effect, and degradable under field conditions (factors), noresidue.
Detailed description of the invention
Applicant is in long-term research process, by the selection to component, and the optimization in proportioning, thus obtain prawn composite immune reinforcing agent of the present invention, this immunopotentiator not only effectively can strengthen the immunity of prawn, and animal will be caused to occur the problems such as grazing rate reduction as other reinforcing agent existing, thus facilitate the present invention.
Prawn composite immune reinforcing agent of the present invention, by weight percentage, be mixed by following component: laminarin 5-10%, astragalus polyose 10-20%, zymosan 20-30%, shitosan 20-30%, allicin 5-10%, vitamin C 5-15%, secondary powder 10-30%.
Embodiment provided below, just understands the present invention to help, instead of formation plays restrictive effect to scope, simply changes, all belong to the scope of protection of present invention under concept thereof of the present invention to the present invention.
The each component of immunopotentiator of the present invention is the commercially available prod in aquatic feeds field, and prawn feed also adopts commercially available prod.
Embodiment 1:
Take laminarin 70g, astragalus polyose 160g, zymosan 200g, shitosan 250g, allicin 50g, vitamin C 100g, secondary powder 170g, is uniformly mixed, cross 100 mesh sieves, namely make a kind of prawn immunopotentiator, then be added in aquatic feeds according to 0.2% ratio.
Culture experiment result shows, experimental group prawn survival rate is 95%, and the survival rate of control group is 82%; The prawn specific growth rate of experimental group is 11.1%, and the specific growth rate of control group is 8.3%; The feed coefficient of experimental group is 2.38, and the feed coefficient of control group is 3.19.
Embodiment 2:
Take laminarin 70g, astragalus polyose 160g, zymosan 200g, shitosan 250g, allicin 50g, vitamin C 100g, secondary powder 170g, is uniformly mixed, cross 100 mesh sieves, namely make a kind of prawn immunopotentiator, then be added in aquatic feeds according to 0.2% ratio.
Culture experiment, Penaeus Vannmei is fed and is added Immune-enhancing effect agent feedstuff after 30 days, infects white spot syndrome virus, and attack poison after 10 days, prawn survival rate is 86%, and is 35% with the survival rate of immunopotentiator group.
Embodiment 3:
Take laminarin 70g, zymosan 200g, shitosan 250g, allicin 50g, vitamin C 100g, secondary powder 330g, is uniformly mixed, cross 100 mesh sieves, namely make a kind of aquiculture animal immunopotentiator, then be added in aquatic feeds according to 0.2% ratio.
Culture experiment, Penaeus Vannmei is fed and is added Immune-enhancing effect agent feedstuff after 30 days, infects white spot syndrome virus, and attack poison after 10 days, prawn survival rate is 70%, and is 37% with the survival rate of immunopotentiator group.Owing to lacking the synergy of astragalus polyose in this routine immunity additive, therefore prawn survival rate is not as the height in embodiment 2.
Embodiment 4:
Take laminarin 70g, astragalus polyose 160g, zymosan 200g, shitosan 250g, vitamin C 100g, secondary powder 220g, is uniformly mixed, and crosses 100 mesh sieves, namely makes a kind of prawn immunopotentiator, then be added in aquatic feeds according to 0.2% ratio.
Culture experiment, Penaeus Vannmei is fed and is added Immune-enhancing effect agent feedstuff after 30 days, infect white spot syndrome virus, attack poison after 10 days, prawn survival rate is 84%, suitable with the survival rate of embodiment 2, but owing to lacking allicin, prawn specific growth rate is 9.2%, and feed coefficient is 2.84, and the prawn speed of growth obviously reduces.
Act synergistically between each component that the above results shows prawn composite immune reinforcing agent of the present invention, thus ensure that the effect serving immunity, and the growth of prawn can not be affected.And applicant finds, when not adding vitamin C and shitosan, although the composite immune reinforcing agent of preparation also has good immune effect, after using, the grazing rate of prawn obviously declines, and causes the speed of growth to reduce.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
