Abstract

The invention discloses a penaeus vannamei phagostimulant. The penaeus vannamei phagostimulant comprises following components in parts by weight: 10-15 parts of glycine betaine, 6-8 parts of taurine, 2-3 parts of nucleotide, 10-15 parts of alanine, 10-15 parts of glycine, 3-5 parts of smoked plums,1-4 parts of spina date seeds, 2-6 parts of mints and 3-6 parts of rhizoma kaempferiae. According to the penaeus vannamei phagostimulant, the phagostimulant which is 0.05%-2% of the weight of penaeus vannamei compound feeds is added into the penaeus vannamei compound feeds so as to cover bad smell in the compound feeds and stimulate sensory organs of penaeus vannamei to promote the penaeus vannamei to ingest and accelerate the growth; furthermore, the phagostimulant is used for inducing the penaeus vannamei to ingest so as to reduce residual feeds in a water body, increase the utilization rate of the feeds and alleviate secondary pollution to the water by the residual feeds, and furthermore, disease risks of the penaeus vannamei are reduced and the survival rate of the penaeus vannamei is increased.

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, started 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 and can improve feed palatability, strengthen animal appetite, improve animal feed intake, strengthen digestion and the absorption of feed, thereby improve feed efficiency, increase cultured output.In addition, mixed feed, in production and storage process, has more or less lost original color and luster and local flavor, even also has special stink, even the mixed feed of comprehensive nutrition, its culture efficiency also there will be very large difference.In feed, add the seasoning phagostimulant that some bring out appetite, increase digestive juice secretion effect, can improve quality, the raising efficiency of feed utilization of feed, 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, improves survival rate.

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

As preferably, the weight portion of each component is: 12 parts of betaines, 7 parts of taurines, 2.5 parts, nucleotides, 13 parts of alanine, 12 parts of glycine, 4.6 parts of dark plums, 3.5 parts of spina date seeds, 4 parts of peppermints, 4 parts of kaempferia galamgas.

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

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

The specific embodiment

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

Embodiment 1

Penaeus Vannmei phagostimulant formula: 10 parts of betaines, 6 parts of taurines, 2 parts, nucleotides, 10 parts of alanine, 10 parts of glycine, 3 parts of dark plums, 1 part of spina date seed, 2 parts of peppermints, 3 parts of kaempferia galamgas.

Embodiment 2

Penaeus Vannmei phagostimulant formula: 12 parts of betaines, 7 parts of taurines, 2.5 parts, nucleotides, 13 parts of alanine, 12 parts of glycine, 4.6 parts of dark plums, 3.5 parts of spina date seeds, 4 parts of peppermints, 4 parts of kaempferia galamgas.

Embodiment 3

Penaeus Vannmei phagostimulant formula: 15 parts of betaines, 8 parts of taurines, 3 parts, nucleotides, 15 parts of alanine, 15 parts of glycine, 5 parts of dark plums, 4 parts of spina date seeds, 6 parts of peppermints, 6 parts of kaempferia galamgas.

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

Buying Penaeus Vannmei seedling (total length 1cm left and right), through glass fiber reinforced plastic breeding after 1 month, therefrom choose shrimp seedling 120 tails of average weight 0.5g left and right, be divided at random 4 groups, every group of 30 tails, put into the glass jar that specification is 90 ㎝ * 60, ㎝ * 45 ㎝ for every group, the salinity that in cylinder, injection prepares in advance for 2 days is 3 ‰～4 ‰ seawater.Each cylinder condition of water quality is consistent, PH7.9～8.7, and below ammoniacal nitrogen 2mg/L, dissolved oxygen 8.2～12.6mg/L.In process of the test, with inflator pump, restart oxygenation always, before throwing something and feeding every morning with siphon pipe by ight soil and residual feed sucking-off, change weekly water 1 time, with the C5H6Br2N2O2 of 0.15mg/L, carry out water body disinfection simultaneously.22～28 ℃ of duration of test water temperatures, experimental group also adds 1% phagostimulant on the basis of basal feed (powder that crude protein content is 36%), experimental group A, B, C add respectively the phagostimulant of embodiment 1,2,3, the control group basal feed of only throwing something and feeding, 3 feeds (8: 30,13 points, 18 respectively throw something and feed once) of throwing something and feeding every day, after throwing something and feeding, 1h observes, and according to bait residue situation, adjusts 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 situation of ingesting is basically identical, all without residual bait, occurs, within every 3 days, adjusts a feeding volume.Be adjusted to 700mg(the 24th day) after, starting to occur difference, test whole process is ingested situation in Table 2.

The growing state of table 1 Penaeus Vannmei

The situation comparison of ingesting of omnidistance each group of table 2 test

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.The interpolation of this explanation phagostimulant not only can promote the growth of prawn, has also reduced aquaculture cost, has saved feed, and water quality has also been played to improvement effect, thereby reduces the pest and disease risk of aquaculture shrimp, protection of the environment, the quality of raising aquatic products.Food calling effect be take experimental group B as best.
