Abstract

The invention relates to a growth promoter for post larvae of litopenaeus vannamei, which comprises the following components in percentage by weight: 40-60 percent of phospholipid, 50-100 percent of vitamin C-2-polyphosphate ester, 25-50 percent of vitamin E, 30-50 percent of digestive enzyme, 20-30 percent of vitamin A, 30-50 percent of beta-glucan and 1-5 percent of clamworm powder. The invention has the following advantages that: (1) the activity and the growth speed of the post larvae of litopenaeus vannamei are increased obviously; (2) the immunity of the post larvae of litopenaeus vannamei is enhanced obviously, and the survival rate is increased; (3) the growth promoter has the addition amount of only 0.2-0.3% when used as a feed additive for a particle feed of the post larvae of litopenaeus vannamei; (4) no adverse effect on the palatability of the feed exists; and (5) the source of the raw materials is stable, the cost is low, and the production process is simple.

Description

The young shrimp of a kind of Environment of Litopenaeus vannamei Low is used growth promoter
Technical field
The present invention relates to a kind of feed addictive, particularly relate to the young shrimp of a kind of Environment of Litopenaeus vannamei Low and use growth promoter.
Background technology
The kind that Environment of Litopenaeus vannamei Low (Litopenaeus vannamei) is an area maximum in China's prawn culturing, output is the highest also is the shrimps product of China's export volume maximum.For improving survival rate, grow seedlings and use heavy dose of antibacterials often; Simultaneously, the way that also generally adopts high temperature to grow seedlings during prawn seed-rearing is accelerated the development by metamorphosis of the young, to shorten seedling raise period, reduces seedling cost.But the raiser generally believe " high temperature seedling " and heavy dose of use that antibiotic shrimp seedling is relatively slow in the forming stage speed of growth, a little less than the premunition, easily ill.Because problems such as medicament residue and bacillary drug resistance, restriction uses antibiotic cry more and more higher in the world, if between nursery stage, in young shrimp feed, improve its degree of utilizing to feed by adding growth promoter, satisfy its demand to nutriment, just can improve the speed of growth, the body disease-resistant power of young shrimp, thereby improve survival rate and the vigor of young shrimp.Just can reduce or even stop to use in the seedling raising process antibiotic.
Summary of the invention
The object of the invention provides the young shrimp of a kind of Environment of Litopenaeus vannamei Low and uses growth promoter, and it can overcome above-mentioned defective.
Its component of the present invention and percetage by weight scope are respectively: phosphatidase 14 0-60; Vitamin C-2-polyphosphate 50-100; Vitamin E 25-50; Digestive ferment 30-50; Vitamin A 20-30; Beta glucan 30-50; Clam worm powder 1-5.
The present invention has following advantage: (1) obviously improves the young shrimp activity of Environment of Litopenaeus vannamei Low and the speed of growth; (2) obviously strengthen the immunity of organisms of the young shrimp of Environment of Litopenaeus vannamei Low, improved survival rate; (3) use in the young shrimp particulate of Environment of Litopenaeus vannamei Low feed as feed addictive, additive capacity only is 0.2-0.3%; (4) the present invention does not have any harmful effect to the feed palatability; (5) its raw material source of the present invention is stable, cheap, and production technology is simple.
The specific embodiment
Take by weighing 40kg phosphatide, 50kg vitamin C-2-polyphosphate, 25kg vitamin E, 30kg digestive ferment, 20kg vitamin A, 30kg beta glucan, 3kg clam worm powder.The even mixing of these 7 kinds of materials is the young shrimp of Environment of Litopenaeus vannamei Low of the present invention uses growth promoter.It satisfies the young shrimp nutritional need of Environment of Litopenaeus vannamei Low, improves the young shrimp speed of growth and immunity of organisms, improves vigor and the survival rate of young shrimp.
Embodiment 1
2008-2009 shows in the experiment of Zhanjiang City, Guangdong Province and Maoming City, uses the strong agent of this growth promotion can make the speed of growth of young shrimp improve 19.30%-21.15% respectively in the young shrimp of Environment of Litopenaeus vannamei Low is cultivated, and survival rate improves 20.40%-21.76% respectively.
Zhanjiang, the young shrimp aquaculture experimental result of Maoming Environment of Litopenaeus vannamei Low
