Abstract
The present invention discloses one kind of prawn feed additive. The prawn feed additive is compounded with Chinese herbal medicine powder in 8-12 weight portions and solid lichen-forming bacillus material in 12-18 weight portions. The Chinese herbal medicine powder is prepared with isatis root, forthythia, astragalus root, agastache, Viola yedoensis and Chinese goldthread and through stoving andcrushing. The solid lichen-forming bacillus material contains lichen-forming bacillus in 10<9> CFU/g. The prawn feed additive is added into prawn feed in the added amount of 0.15-0.50 wt% before the feed is pelletized into 1.5 mm size grains. By means of the synergistic effects of the Chinese medicine materials and the lichen-forming bacillus, the prawn feed additive has the functions of raising the activity of digestive enzyme, promoting the growth of prawn and raising the survival rate of prawn.
Description
Technical field
The present invention relates to a kind of prawn feed additive.
Technical background
Along with the fast development of shrimp culture industry and improving constantly of intensive culture degree, the disease problem is serious day by day.In traditional pest control method, antibiotic and chemicals are used as main means and use in a large number, have caused pathogen to develop immunity to drugs, and result of treatment descends; Simultaneously, because medicine residual, have a strong impact on the health and the Environmental security of consumer groups.Because the aquatic products medicament residue exceeds standard, and causes products export limited, has had a strong impact on the competitiveness of China's aquatic products, has hindered the developing of domestic and international market, has caused enormous economic loss.
Summary of the invention
The object of the present invention is to provide a kind of prawn feed additive, can improve the digestive enzyme activity of prawn, the growth of promotion cultured prawn significantly, reduce the disease problem of prawn culturing.
Prawn feed additive of the present invention is composited by the proportioning of following raw material with parts by weight:
Chinese herbal medicine powder 8-12 bacillus licheniformis solid material 12-18.
Compound Chinese herbal medicine powder of the present invention is composited after being pulverized by the Radix Isatidis that waits weight portion, the capsule of weeping forsythia, the Radix Astragali, wrinkled giant hyssop, prairie milk vetch and coptis drying.
The bacillus licheniformis flora is 10 in the bacillus licheniformis complex solid material of the present invention
9CFU/g.
The percentage by weight that adds in prawn feed of compound additive of the present invention is 0.15%-0.50%, and the particle that particle diameter is 1.5mm is made in granulation behind the mixing.
Beneficial effect of the present invention: the present invention adds an amount of Chinese herbal medicine and bacillus licheniformis in prawn feed, by their synergy, can obviously improve digestive enzyme activity, promote the growth of prawn and improve the prawn survival rate, have good economic benefit and social benefit, help the sustainable sound development of prawn culturing, meet the development strategy trend of aquatic feeds.
The specific embodiment
Radix Isatidis, the capsule of weeping forsythia, the Radix Astragali, wrinkled giant hyssop, prairie milk vetch and the coptis of weight portion such as get, concrete preparation process is: bulk drug → first drying → secondary drying → coarse crushing → ultramicro grinding → sieve → composite, make compound Chinese herbal medicine powder.
Get culture medium (composition: cornstarch 2%, peptone 2.5%, corn steep liquor 1.5%, NaH2PO40.8%; PH7.2-7.4) → sterilize (121 ℃, 30min) → cooling (30 ℃) → (30 ℃ of (inoculum concentration 5%) → seed tank culture of inoculation, 18h) → enlarge and cultivate (30 ℃, 24h) → centrifugal → be written into carrier (wheat bran) → drying → pulverizing, make bacillus licheniformis complex solid material, the bacillus licheniformis flora is 10 in the above-mentioned bacillus licheniformis complex solid material
9CFU/g.
Take by weighing the above-mentioned raw material that makes, mix, make the prawn feed additive, wherein Chinese herbal medicine powder 8-12 with the proportioning of parts by weight; Bacillus licheniformis solid material 12-18.
Above-mentioned compound additive directly adds in the prawn feed, and addition is the 0.15%-0.50% of prawn feed weight, and the particle that particle diameter is 1.5mm is made in granulation behind the mixing.
The experiment of feeding prawn with the present invention is as follows:
Experimental result adopts average ± standard deviation to represent, uses one-way analysis of variance (ANOVA) statistics, when having significant difference between the ANOVA demonstration is handled, uses Duncan ' s multiple ratio with the analysis bank differences.SPSS 11.5 statistical softwares are used in all statistical analyses, are the significance of difference with P＜0.05.
Prepare five kinds of prawn feeds, feed A: prawn basal feed; Feed B: in basal feed, add 0.2% above-mentioned compound Chinese herbal medicine powder; Feed C: bacillus licheniformis feed group, in basal feed, add 0.30% above-mentioned bacillus licheniformis; Feed D: in basal feed, add 0.25% Chinese herbal medicine of the present invention and bacillus licheniformis compound additive; Feed E: in basal feed, add 0.50% Chinese herbal medicine of the present invention and bacillus licheniformis compound additive.The particle that particle diameter is 1.5mm is made in granulation behind the mixing.
With above-mentioned prawn mixed feed, fed initial body weight 2.03g Environment of Litopenaeus vannamei Low (Litopenaeus vannamei) 70 days.In indoor cement circle pond 2.0m
3Grouping is carried out.Culturing water filters through post precipitation.Shrimp 80 tails are supported in every pond, and every group of 3 in feed is parallel.Keep continuous charge.The breeding process water temperature is 19.6-25.2 ℃, salinity 30～31 ‰.
Culture efficiency sees Table 1.(feed A) compares with control group, in the feed separately or associating wherein add bacillus licheniformis and Chinese herbal medicine, can both promote the growth of prawn.Especially, feed D group is significantly higher than other each group, does not compare with the Chinese herbal medicine group with adding bacillus licheniformis, and rate of body weight gain improves 35%.
