Description

A kind of feed addictive improving mandarin fish premunition

Technical field

The invention belongs to technical field of aquaculture, be specifically related to a kind of feed addictive improving mandarin fish premunition.

Background technology

Mandarin fish cries again huge legendary turtle flower fish, carnivorous, scale fiss; Belong to the fat section fish in taxology.Mandarin fish health is flat-sided, and back is swelled, and health is thicker, tip.It is the one in China " four large fresh water name fishes ".Mandarin fish fine and tender taste, sting less and meat is many, its meat is flap, delicious flavour, is the good merchantable brand in fish in fact.Therefore mandarin fish cultivation also more and more scale.But breed fish in process in scale; easy band worm, bacterium enter pond; the 7-9 month mandarin fish incidence of disease is higher; principal disease is trichodinasis, doctylogyrosis, fin rot etc., usually needs to strengthen water quality management in cultivation, and is aided with the medicine increasing mandarin fish disease resistance; now antibiotics chemicals mostly is to the medicine that mandarin fish is thrown in; although the effect preventing disease can be played, usually can affect mandarin fish meat, therefore need a kind of green for the antibacterial disease-resistant medicine of mandarin fish.

Summary of the invention

The object of the invention is for existing problem, provide a kind of feed addictive improving mandarin fish premunition.

The present invention is achieved by the following technical solutions: a kind of feed addictive improving mandarin fish premunition, be made up of the raw material of following weight portion: seeds of Urtica cannabina extract 15-25 part, Snakegourd Fruit 20-35 part, herba fibraureae recisae 10-15 part, Chinese mahonia 8-12 part, balloonflower root 6-8 part, bittersweet 6-8 part, banksia rose 2-4 part, hay 10-15 part, garlic 6-8 part, red sage root 2-8 part, cactus 2-8 part.

As further improvement of these options, described seeds of Urtica cannabina extract is ligroin extraction, and extract concentrations is 5mg/mL.

As further improvement of these options, preparation method is as follows:

(1) above-mentioned other raw materials except seeds of Urtica cannabina extract are ground to form segmentation respectively by corresponding component, mixing, obtains mixture;

(2) said mixture is joined in 4-6 times of water gaging and decoct, decoct 2-3 hour at every turn, decocts 3 times, boiled rear filtration at every turn, filtrate collection is mixed, by mixed liquor simmer down to paste;

(3) paste being joined the determining alcohol being equivalent to its quality 2-4 times amount is in the ethanolic solution of 92%-96%, is stirred to and dissolves completely, and then less than 5 DEG C leave standstill 6-8 hour, filter subsequently, filtrate is carried out reduced pressure concentration, obtains lotion and pulverizes;

(4) in lotion is pulverized, add the seeds of Urtica cannabina extract of corresponding proportion, puddle evenly, with ring mode grit mechanism grain, particle diameter is 1-2.5mm.

Bacteriostatic active ingredients mainly phenolic compound in seeds of Urtica cannabina ligroin extraction, organic acid and tannins, phenolic compound primarily of Phenylpropanoid Glycosides class (propenyl benzene, benzenpropanoic acid, cumarin, lignin etc.), flavonoids, polyphenol compound.Phenolic compound has the effects such as anti-inflammatory, antiviral, antibacterial, pain relieving more.Tannin is the poly phenolic compound of a class formation more complicated, Bearberry Extract, and take orally and can treat the diseases such as intestines and stomach is hemorrhage, watery diarrhea, the plasm that can solidify microorganism has certain antibacterial action.Organic acid has the antibiotic left and right of class more, the effect of tool anti-inflammation.

The present invention has the following advantages compared to existing technology: the feed addictive provided in the present invention can improve the immunity of mandarin fish body, reduce the use of disease-resistant chemical drugs, improve the survival rate of mandarin fish, and this raw materials of feed additives is all Chinese herbal medicine, medicament residue can not be caused, thus ensure the quality of mandarin fish, can not be detrimental to health after edible, additive uses and also can not work the mischief to water body and environment.

Detailed description of the invention

Embodiment

Improve a feed addictive for mandarin fish premunition, be made up of the raw material of following weight portion: seeds of Urtica cannabina extract 20 parts, Snakegourd Fruit 20 parts, herba fibraureae recisae 12 parts, Chinese mahonia 10 parts, balloonflower root 8 parts, bittersweet 6 parts, the banksia rose 2 parts, 10 parts, hay, 6 parts, garlic, the red sage root 4 parts, 2 parts, cactus.

Wherein, described seeds of Urtica cannabina extract is ligroin extraction, and extract concentrations is 5mg/mL.

Wherein, preparation method is as follows:

(1) above-mentioned other raw materials except seeds of Urtica cannabina extract are ground to form segmentation respectively by corresponding component, mixing, obtains mixture;

(2) said mixture is joined in 5 times of water gagings and decoct, decoct 2-3 hour at every turn, decocts 3 times, boiled rear filtration at every turn, filtrate collection is mixed, by mixed liquor simmer down to paste;

(3) paste being joined the determining alcohol being equivalent to its quality 3 times amount is in the ethanolic solution of 95%, is stirred to and dissolves completely, and then less than 5 DEG C leave standstill 6-8 hour, filter subsequently, filtrate is carried out reduced pressure concentration, obtains lotion and pulverizes;

(4) in lotion is pulverized, add the seeds of Urtica cannabina extract of corresponding proportion, puddle evenly, with ring mode grit mechanism grain, particle diameter is 1-2.5mm or 3-4mm.

Feed addictive is made according to the composition of raw materials in above-mentioned embodiment and preparation method, add in the daily feed of mandarin fish, from April, to feed mandarin fish 6 months, experiment terminates the activity of rear detection different tissues lysozyme, during the 7-9 month, the ratio of feeding of feed addictive is 5%, and the ratio of feeding of other times feed addictive is 2%.

Select with a collection of, the healthy mandarin fish that size body weight is substantially identical cultivates, setting control group, and experimental group, often organizes 200 tails, and the mandarin fish often organizing random selecting 10% during detection detects, and the mean value asked is end product, show that data are as following table:

(unit: U*g ^-1* min ^-1)

Project	Serum	Spleen	Kidney	The cheek	Intestinal mucosa
						Control group	121.95	558.33	909.52	45.37	109.55
Experimental group	124.27	558.49	911.24	45.88	126.41

Table 1

Data as can be seen from table 1, adopt each position lysozyme activity in the mandarin fish body of feed addictive feeding in the present invention to be all improved to some extent, thus prove that it has and better work as disease resistance, and immune level is improved significantly.
