Background technology
Sea cucumber has higher edible medical value and economic worth, the precious marine product with special nourishing and nutrition and health care multi-efficiency of extensively being admitted.Along with the increase of people to stichopus japonicus demand, adopt and catch intensity and increase gradually, cause China's Holothurian Resources amount sharply to decline.Meanwhile, sea cucumber is propagated the continuous expansion of scale artificially, and sea cucumber germplasm degradation phenomena is on the rise, and the farming disease harms series of problems such as be on the rise, is seriously restricting the development of sea cucumber industry.
Immunopotentiator refers to by different modes to have and promote or bring out host to produce defense reaction, reaches the material that strengthens immunity of organisms.Main Function, in the nospecific immunity of aquatic products invertebrate, activates the immune defense system of body, thereby reach, strengthens the object that immunity improves its resistance against diseases.Immunopotentiator has safe ready, and noresidue and sphere of action be feature widely, aspect resistance disease and raising immunity of organisms, is obviously being better than vaccine and antibiotic.In current aquatic animal disease prevention and cure, antibiotic still plays a part main, but considers its resistance to the action of a drug and residue problem, and antibiotic is eliminated by people day by day, instead will be immunopotentiator and vaccine etc., vaccine is owing to there being specificity, therefore, and in disease preventing and treating, the broad spectrum activity that effect is not so good as immunopotentiator is good, using method and level of processing at vaccine are in addition limited, and therefore, immunopotentiator is subject to people's absolute favor at present.Aquaculture take " anti-overweight control " be principle, and the effect of immunopotentiator exactly focuses on anti-going up, and its also highly significant of curative effect aspect controlling.In addition, immunopotentiator is used jointly as adjuvant and vaccine, more can strengthen the curative effect of vaccine, and therefore, its development field is further widened.Along with the using method to vaccine reinforcing agent, dosage and time limit and further deep to the research of aquatic livestock immunologic mechanism, immunopotentiator will become control aquatic animal disease, improves very effectively approach of immunity.At present, by multi-source, multipath mode develops low toxicity, and efficient, quick-acting, Novel immune reinforcing agent has become the main trend of development longer.
Summary of the invention
Technical problem solved by the invention is to provide the young children's ginseng of a kind of stichopus japonicus composite immune reinforcing agent and preparation method thereof, it is added in feed and feeds and raise young children's ginseng, can improve the anti-stress ability of young children's ginseng, the damage that minimizing stress bring, the immunocompetence that strengthens body, improves its survival rate.
Improve a composite immune reinforcing agent for the young children ginseng anti-stress ability of stichopus japonicus, by the material of following parts by weight, formed:

Test example:
One, the raising of stichopus japonicus and management
Select the same a collection of stichopus japonicus of hatching then as ginseng for experiment, initial body weight is 3.90 ± 0.84g.Experiment arranges 5 groups, is respectively control group, embodiment 1, embodiment 2, embodiment 3, embodiment 4.Wherein control group is thrown something and fed and is not added the apostichopus japonicus Selenka feed of immunopotentiator, and other embodiment groups have been added respectively the immunopotentiator of 0.2-0.5% on the basis of control group, and it forms and adding proportion is carried out according to embodiment 1-4.Every group 3 parallel, and each parallel 30 stichopus japonicus, throws something and feeds 1 every day, and Feeding time is 17:00, is satiated with food and throws something and feeds, and next day, 8:00 absorbed residual bait and ight soil.Continuous charge between feeding period, water temperature is controlled at 15 ± 0.5 ℃, salinity 32, PH7.8-8.2, dissolved oxygen is not less than 5mg/L.
Two, the collection of stichopus japonicus sample, analysis and calculating
Respectively within after throwing something and feeding the 10th, 20,30,40 and 50 days, measuring the various immuno-enzymatic activity of stichopus japonicus and growing state.Calculate the specific growth rate of stichopus japonicus.Computing formula is as follows:
Survival rate (%)=100 * (Nt-No)/No
Rate of body weight gain (WG, %)=100 * (Wt-Wo)/Wo
Specific growth rate (SGR, %)=100 * (ln Wt-ln Wo)/t
Wherein, No is respectively initial number of each parallel stichopus japonicus and an eventually last number with Nt, and Wt and Wo are respectively initial body weight and whole opisthosoma weight, and t is experiment number of days.
Get coelomic fluid, whole process is carried out on ice chest, prevents enzyme deactivation.Coelomic fluid is packed in 1.5mL centrifuge tube, be temporarily kept in 4 ℃ of refrigerators.Centrifugal, 3000r/min, 4 ℃ of centrifugal 10min, get supernatant ,-80 ℃ of preservations.With ELIASA, measure its AKP of absorbance measurement, ACP, LSZ and SOD enzyme activity.
Adopt SPSS 11.5for Windows to carry out one-way analysis of variance to the data obtained.
Three, experimental result is in Table 1 and table 2:
