Abstract

The invention discloses a kind of Penaeus Vannmei phagostimulant, comprise the component of following weight portion: betaine 10 ~ 15 parts, taurine 6 ~ 8 parts, 2 ~ 3 parts, nucleotides, alanine 10 ~ 15 parts, glycine 10 ~ 15 parts, dark plum 3 ~ 5 parts, spina date seed 1 ~ 4 part, peppermint 2 ~ 6 parts, kaempferia galamga 3 ~ 6 parts.The phagostimulant of its weight 0.05 ~ 2% is added in litopenaeus vannamei compound feed, the bad smell in mixed feed can be covered, stimulate the sense organ of prawn simultaneously, promote that prawn ingests, thus accelerate growth, on the other hand, ingested by phagostimulant induction prawn, the residual bait of feed in water body can be reduced, improve efficiency of feed utilization, reduce the secondary pollution of superfluous feed to water body, thus reduce the pest and disease risk of prawn, improve the survival rate of prawn.

Description

Penaeus Vannmei phagostimulant

Technical field

The invention belongs to aquatic livestock additive technology field, be specifically related to a kind of Penaeus Vannmei phagostimulant.

Background technology

Penaeus Vannmei is one of three large economic shrimps in the world, has nutritional need lower, and growth is fast, and premunition is strong, eurysalinity, adaptable characteristic.Along with the invention of the intensive diseases prevention cultural technique of Penaeus Vannmei and the breakthrough of improvement and total man's work rearing of fingerling, start the upsurge of China's shrimp culture industry.Artifical compound feed is the material base of Penaeus Vannmei healthy aquaculture, grasps the nutritional need of prawn, selects the feed of high-quality low-cost to be directly connected to the economic benefit of prawn culturing.

In prawn feed, add phagostimulant can improve feed palatability, strengthen animal appetite, improve animal feed intake, strengthen the absorption and digestion of feed, thus improve feed efficiency, increase cultured output.In addition, mixed feed is in production and storage process, and more or less lose original color and luster and local flavor, even also have special stink, even the mixed feed of comprehensive nutrition, its culture efficiency also there will be very large difference.In feed, add some bring out appetite, increase the seasoning phagostimulant of digestive juice secretion effect, the quality of feed can be improved, improve efficiency of feed utilization, reduce feed cost, increase cultivation income.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of Penaeus Vannmei phagostimulant, adds this phagostimulant and can strengthen prawn food ration in prawn mixed feed, promotes prawn growth, reduces feed coefficient, improve survival rate.

Technical scheme provided by the invention is to provide a kind of Penaeus Vannmei phagostimulant, comprises the component of following weight portion: betaine 10 ~ 15 parts, taurine 6 ~ 8 parts, 2 ~ 3 parts, nucleotides, alanine 10 ~ 15 parts, glycine 10 ~ 15 parts, dark plum 3 ~ 5 parts, spina date seed 1 ~ 4 part, peppermint 2 ~ 6 parts, kaempferia galamga 3 ~ 6 parts.

As preferably, the weight portion of each component is: betaine 12 parts, taurine 7 parts, 2.5 parts, nucleotides, alanine 13 parts, glycine 12 parts, dark plum 4.6 parts, spina date seed 3.5 parts, peppermint 4 parts, kaempferia galamga 4 parts.

The addition of this phagostimulant in Penaeus Vannmei artifical compound feed is 0.05 ~ 2%.

Penaeus Vannmei phagostimulant of the present invention, the bad smell in mixed feed can be covered, stimulate the sense organ of prawn simultaneously, promote that prawn ingests, thus accelerate growth, on the other hand, ingested by phagostimulant induction prawn, the residual bait of feed in water body can be reduced, improve efficiency of feed utilization, reduce the secondary pollution of superfluous feed to water body, thus reduce the pest and disease risk of prawn, improve the survival rate of prawn.

Detailed description of the invention

The present invention is further elaborated for following specific embodiment, but not as a limitation of the invention.

Embodiment 1

Penaeus Vannmei phagostimulant is filled a prescription: betaine 10 parts, taurine 6 parts, 2 parts, nucleotides, alanine 10 parts, glycine 10 parts, dark plum 3 parts, spina date seed 1 part, peppermint 2 parts, kaempferia galamga 3 parts.

Embodiment 2

Penaeus Vannmei phagostimulant is filled a prescription: betaine 12 parts, taurine 7 parts, 2.5 parts, nucleotides, alanine 13 parts, glycine 12 parts, dark plum 4.6 parts, spina date seed 3.5 parts, peppermint 4 parts, kaempferia galamga 4 parts.

Embodiment 3

Penaeus Vannmei phagostimulant is filled a prescription: betaine 15 parts, taurine 8 parts, 3 parts, nucleotides, alanine 15 parts, glycine 15 parts, dark plum 5 parts, spina date seed 4 parts, peppermint 6 parts, kaempferia galamga 6 parts.

For verifying the effect of phagostimulant of the present invention, applicant starts the feeding experiment of 42 days by a definite date on July 15th, 2013.

Buying Penaeus Vannmei seedling (about total length 1cm), through glass fiber reinforced plastic breeding after 1 month, therefrom choose shrimp seedling 120 tail of about average weight 0.5g, be divided into 4 groups at random, often organize 30 tails, often group puts into the glass jar that specification is 90 ㎝ × 60, ㎝ × 45 ㎝, injects the seawater that the salinity prepared for 2 days is in advance 3 ‰ ~ 4 ‰ in cylinder.Each cylinder condition of water quality is consistent, PH7.9 ~ 8.7, below ammoniacal nitrogen 2mg/L, dissolved oxygen 8.2 ~ 12.6mg/L.Restart oxygenation with inflator pump in process of the test always, before throwing something and feeding every morning with siphon pipe by ight soil and residual feed sucking-off, change weekly water 1 time, carry out water body disinfection with the C5H6Br2N2O2 of 0.15mg/L simultaneously.Duration of test water temperature 22 ~ 28 DEG C, experimental group also adds the phagostimulant of 1% on the basis of basal feed (crude protein content is the powder of 36%), experimental group A, B, C add the phagostimulant of embodiment 1,2,3 respectively, control group is is only thrown something and fed basal feed, to throw something and feed every day 3 feeds (8: 30,13 points, 18 respectively throw something and feed once), after throwing something and feeding, 1h observes, according to bait residue situation adjustment feeding volume.Test period is 42 days, measures the TBW of every cylinder shrimp in test initial stage and latter stage, and South America prawn growing state sees the following form 1.This experiment feeding volume increases gradually from initial 200mg, until 600mg, each group of situation of ingesting is basically identical, all occurs without residual bait, adjustment in an every 3 days feeding volume.Be adjusted to 700mg(the 24th day) after, start to occur difference, test whole process ingests situation in table 2.

The growing state of table 1 Penaeus Vannmei

Table 2 is tested the omnidistance each group of situation of ingesting and is compared

As can be seen from the above table, experimental group feedstuff feeding amount, prawn weight gain and survival rate are all higher than control group, and meanwhile, experimental group feed coefficient is also starkly lower than control group.This illustrates that the interpolation of phagostimulant not only can promote the growth of prawn, also reduces aquaculture cost, has saved feed, also served improvement result to water quality, thus reduces the pest and disease risk of aquaculture shrimp, protection of the environment, improves the quality of aquatic products.Phagostimulating effect with experimental group B for the best.
