Contrast test:
Choose long (1.15 ± 0.04) cm of being of average body, average weight experimentizes for the prawn of (0.03 ± 0.00) g.
Control group adopts the common shrimp feed formula that does not add Chinese herbal medicine; Test group 1 adopts the Chinese herbal medicine of the prescription that has added embodiment 1 (additive), and the percentage by weight that adds is 1%.Test group 2 adopts the Chinese herbal medicine of the prescription that has added embodiment 2 (additive), and the percentage by weight that adds is 1.4%; Test group 3 adopts the Chinese herbal medicine of the prescription that has added embodiment 3 (additive), and the percentage by weight that adds is 2.2%; Concrete prescription is seen table 1.
The common shrimp feed of table 1. is formed with the prescription of the feed that adds Chinese herb feed additive.
Add in table 2. feed Chinese herb feed additive to the influence of prawn growth performance (mean value ± standard error, n=3)
Visible by table 2, the survival rate and the speed of growth of prawn of adding each test group of Chinese herbal medicine in the feed all is significantly increased, and the survival rate of test group 1, whole opisthosoma is heavy and specific growth rate improves 14.2%, 10.6% and 2.2% respectively; The survival rate of test group 2, whole opisthosoma is heavy and specific growth rate improves 15.1%, 12.3% and 2.5% respectively; The survival rate of test group 3, whole opisthosoma is heavy and specific growth rate improves 15.6%, 13.1% and 3.0% respectively;
Add in table 3. feed Chinese herb feed additive to the influence of prawn immune indexes (mean value ± standard error, n=3)
The height of immune indexes has reflected the height of prawn for the resistance of disease.Can find out from table 3; Each item immune indexes that adds the prawn of Chinese herb feed additive feed has all had and has significantly improved (p < 0.05); Wherein, antalzyme activity, phenol oxidase and the superoxide dismutase activity of prawn are compared with control group and are improved 40%, 50.8% and 45.5% respectively in the test group 1; The antalzyme activity of prawn, phenol oxidase and superoxide dismutase activity are compared with control group and are improved 53.3%, 62.2% and 52.7% respectively in the test group 2; The antalzyme activity of prawn, phenol oxidase and superoxide dismutase activity are compared with control group and are improved 60%, 62.4% and 53.8% respectively in the test group 3.
(Vibrio alginolyticus) attacks poison to test group with prawn with Vibrio anguillarum.Confirm that through trial test the malicious concentration of attacking of Vibrio anguillarum is 106 cfu/ml, ID 50 μ l/ tails, record are attacked the cumulative mortality of each group in the 7d of poison back, see Fig. 1.
The result shows: control group prawn cumulative mortality is 54.0%; And each test group cumulative mortality that adds Chinese herbal medicine in the feed significantly is lower than control group (p < 0.05), and the death rate comparison of test group 1, test group 2 and test group 3 has reduced by 28%, 30% and 31% respectively according to group.
Comprehensive above result of the test, Chinese herbal medicine can significantly improve the speed of growth of prawn, improves the prawn immunocompetence simultaneously; Strengthen the premunition of prawn, for main pathogenic bacteria Vibrio anguillarum good resistance is arranged, prawn is susceptible disease not; Survival rate is greatly enhanced, and significantly promotes productivity effect.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
