Technical Field
The invention relates to a macrobrachium rosenbergii micro-ecological feed compound additive and application thereof, belonging to the technical field of micro-ecological feed compound additives for shrimps.
Background
Due to the fast growth speed, the strong tolerance to temperature and salinity and the strong resistance to some common diseases, the output of the macrobrachium rosenbergii in China in the last decade exceeds 13 million tons, and the macrobrachium rosenbergii becomes a main freshwater product occupying the domestic aquatic market. However, diseases caused by bacterial infection have great influence on the industry, and the development of the macrobrachium rosenbergii breeding industry is seriously influenced.
In order to solve the disease problem, probiotics, synbiotics and other micro-ecological preparations are widely applied to the aquatic product industry, and researches show that the probiotics, the synbiotics and other micro-ecological preparations have the functions of promoting the growth of animals and improving the feed efficiency and the immunity, and also have a great promotion effect on improving the resistance of organisms to pathogens.
At present, in the domestic aquaculture industry, the water quality is generally regulated and controlled by using a microecological preparation in aquaculture water, the growth of fishes and shrimps is promoted, and the occurrence of diseases is reduced. However, the existing microbial ecological agents have many problems, such as the fact that the amount of the microbial ecological agents added into the water body is difficult to ensure, the effect of a single microbial ecological agent is poor, and the existing microbial ecological system in the environment is threatened.

Preferably, the micro-ecological feed mainly comprises fish meal, soybean meal, flour, soybean lecithin, fish oil, shrimp shell meal, zeolite powder, vitamin premix, mineral premix, monocalcium phosphate, choline chloride, ecdysone, vitamin C and sodium alginate.
The micro-ecological feed composite additive for shrimps is applied to preparing the micro-ecological feed for macrobrachium rosenbergii.
When in use, the compound additive is mixed into the micro-ecological feed to ensure that the final probiotic concentration in the feed is (0.5-1.5) multiplied by 108CFU。
When in application, the compound additive is mixed into the micro-ecological feed, so that the mass of the beta-glucan in the feed is 0.1-0.2% of the total mass of the feed.
The technical effects are as follows: compared with the prior art, the micro-ecological feed composite additive for shrimps is simple to operate, practical and feasible in use and wide in application. Can be directly applied to actual culture production, has obvious effects of promoting the growth of the macrobrachium rosenbergii and improving the immunity, has no environmental side effect, and does not influence the water quality of culture water. The composite additive provided by the invention can be added to directly apply the microecologics to the feed, and provides a reference basis for the development of the microecologics in the aquatic feed industry.

Detailed Description
The present invention will be further illustrated with reference to the following specific examples.
Examples
Preparing the micro-ecological feed for the macrobrachium rosenbergii, and adding the composite additive (comprising probiotic component lactic acid tablets)Coccus and yeast, and prebiotic component beta-glucan) into a microecological feed, and different additives are added on the basis of the same microecological feed to form a group of test feeds and four groups of control feeds, wherein the group of the base control microecological feed (GC), the group of Pediococcus acidilactici (GP), the group of Pediococcus acidilactici + Yeast (GPS), the group of Pediococcus acidilactici + Glucan (GPG), and the group of the test feeds Pediococcus acidilactici + Glucan + Yeast (GPGS-the additive of the present invention). And the final concentration of each probiotic in the various feeds was 1X 108The mass of the CFU, beta-glucan is 0.15 percent of the total mass of the feed, and the concentration ratio of the pediococcus acidilactici to the yeast powder is 1: 1.
the formula of the micro-ecological feed is shown in the following table:
Figure BDA0002269583430000031
feeding macrobrachium rosenbergii larvae with initial weight of 0.18 +/-0.01 g by using five feeds respectively, wherein daily feeding amount is 4% of body mass, ensuring that feeding is performed after satiety, measuring and weighing each group of shrimps after 60 days of culture, calculating growth performance of the shrimps, sampling and determining the immunocompetence of each group of shrimps, and simultaneously performing a challenge test by using aeromonas hydrophila to detect the resistance of each group of shrimps.
The test results are shown below:
the growth performance of each group of macrobrachium rosenbergii is shown in table 1, and the microecologics have no significant effect on the survival rate of each group of macrobrachium rosenbergii, but significantly affect the growth performance. The terminal body weight, weight gain rate and specific growth rate of shrimps in the test group GPGS group were significantly increased compared to the same values in the control group. In addition, the test group GPGS group had the lowest feed efficiency for shrimp and was significantly lower than the GC, GP and GPG groups.
The immunocompetence of macrobrachium rosenbergii was evaluated by measuring blood-related indices and expression levels of immune-related genes in the liver and pancreas of the control group and the test group, and the results are shown in fig. 1 to 6, and the total number of blood cells in the GPGS group is higher than those in the GC group and the GPS group. Meanwhile, the respiratory burst activity of shrimps in the GPGS group was higher than that of the GC group, GP group and GPs group. The test group of the shrimps in the GPGS group has a phagocytic index which is obviously higher than that of the shrimps in the GC group, the GPG group and the GPS group, and the shrimps in the GPGS group also have a phagocytic index which is higher than that of the shrimps in the GP group.
The addition of the probiotics resulted in significant differences in the relative expression levels of immune-related genes in the shrimp hepatopancreas.
As shown in FIG. 1, the lectin (lectin) and Toll receptor genes were expressed in the test group GPGS group more than in the four control groups. Meanwhile, the expression amounts of Lysozyme (Lysozyme) and phenol oxidase (proPO) in the test group GPGS were also higher than those in the GC group, GP group and GPG group. Furthermore, the probiotics had no significant effect on IMD gene expression between all groups.
As shown in fig. 2, regarding the relative expression levels of the antioxidant enzyme genes, the superoxide dismutase (SOD) gene expression level of the GPGS group was significantly higher than that of the GC group, and the Catalase (CAT) gene expression level of the GPGS group was significantly higher than that of the GC group, the GP group, and the GPG group. The expression level of glutathione peroxidase (GPxs) genes of the GPGS group was not significantly different from those of the GC group, the GP group and the GPG group. The anti-tumor factor (TNF-alpha) gene expression level of the GPGS group in the test group is higher than that of the GPG group and the GPGS group, and the gene expression level of heat shock protein 70(HSP 70) of the GPGS group is lower than that of the four groups of control groups.
The cumulative mortality of the aeromonas hydrophila after the challenge test is carried out, and the result is shown in fig. 6, the cumulative mortality of the GPGS group is 40% and is significantly lower than that of the GC group.
The above test results all show that: the compound additive prepared by the invention is added into the macrobrachium rosenbergii feed, and has obvious improvement effect on the growth, immunity and resistance of the macrobrachium rosenbergii.
