Abstract
The invention relates to a feed additive capable of promoting the growth of Litopenaeus vannamei in low-salt environment, which comprises ingredients by weight percentages: 30 to 50 percent of KCl in a feed grade, 20 to 30 percent of MgSO4 in a feed grade, 10 to 20 percent of vitamin C-2-poly phosphate, 5 to 10 percent of vitamin E and 5 to 10 percent of selenium methionine, wherein the KCl in the feed grade contains 50 percent of K, and the MgSO4 in the feed grade contains 15 percent of Mg. The invention has the advantages that the weight rate of the Litopenaeus vannamei in the low-salt environment is obviously improved, and the growth of the Litopenaeus vannamei is promoted; the conversion efficiency and the live rate of Litopenaeus vannamei feed are obviously improved, and the feed additive in the compound feed of Litopenaeus vannamei is added only by 0.5 percent to 0.8 percent. The invention has no influence on the palatability and the culture environment of the feed, and raw materials adopted in the feed additive have stable resources, low cost and simple production technology.
Description
Technical field
The present invention relates to a kind of feed addictive, particularly relate to feed additive for promoting growth under a kind of Environment of Litopenaeus vannamei Low low-salt environment.
Technical background
Environment of Litopenaeus vannamei Low (Litopenaeus vannamei) because of it has that premunition is strong, growth is fast, can adapt to the breed of low salinity water territory, delicious meat, relatively low to the forage protein requirement, be easy to carry out characteristics such as high density intensive culture, become one of three big improved seeds that cultured output is the highest in the world.
In recent years, owing to reasons such as outbreak of disease, coastal seawater pollution and market demand increases, the breed of Environment of Litopenaeus vannamei Low significantly advances in the low salinity water territory upcountry from littoral body of sea water, the particularly breed fast development in low salinity water territory, many countries in the world in recent years, the most typical Delta of the Pearl River, Yangtze River Delta, the yellow Bohai Sea Area that comprises China, the Ya Nabama of southern US, Florida, Indiana, Texas etc., and Thailand southern areas.
Yet, the Environment of Litopenaeus vannamei Low low salinity stocking is because body is under the stress situation for a long time to some extent, cause that survival rate is on the low side, growth partially slowly, particularly the prawn culturing late growing stage is slow, the death rate is high, cause being difficult to form big specification individuality, influence product quality.Therefore, form at the inorganic ions of less salt water body and the variation characteristics of prawn metabolic mechanism are developed the feed addictive that promotes the prawn low-salt environment to culture growth rate and survival rate down and just seemed particularly important.Yet, still do not have on the domestic and international market at present at the feed additive for promoting growth product under the Environment of Litopenaeus vannamei Low low-salt environment.
Summary of the invention
The purpose of this invention is to provide feed additive for promoting growth under a kind of Environment of Litopenaeus vannamei Low low-salt environment, it can remedy the deficiencies in the prior art.
Want component of the present invention and percetage by weight scope to be respectively: K content is 50% feed grade KCl, and 30-50:Mg content is 15% feed grade MgSO
4, 20-30; Vitamin C-2-polyphosphate, 10-20; Vitamin E, 5-10: selenium methionine, 5-10.
The present invention has following advantage: (1) obviously improves rate of body weight gain, the promotion growth under the Environment of Litopenaeus vannamei Low low-salt environment; (2) obviously improve the feed conversion efficiency and the survival rate of Environment of Litopenaeus vannamei Low.(3) use in the Environment of Litopenaeus vannamei Low mixed feed as feed addictive, addition only is 0.5%-0.8%.(4) the present invention does not have any harmful effect for the palatability and the breeding environment of feed; (5) its raw material source of the present invention is stable, cheap, and production technology is simple.
The specific embodiment
Take by weighing feed grade KCl (K content is 50%) 40kg, feed grade MgSO
4(Mg content is 15%) 30kg, vitamin C-2-polyphosphate 15kg, vitamin e1 0kg, selenium methionine 5kg evenly are feed additive for promoting growth under the Environment of Litopenaeus vannamei Low low-salt environment of the present invention with these five kinds of mixing of materials.
In May, 2006-August, the feeding experiment on the common shrimp pool, Zhanjiang City, Guangdong shows, use this growth accelerator in the complete period of Environment of Litopenaeus vannamei Low low-salt culturing, the average growth rate of Environment of Litopenaeus vannamei Low improves 12.6% than control group, and feed coefficient improves 16% (seeing the following form) than control group reduction by 19.8%, survival rate.
The Environment of Litopenaeus vannamei Low low salinity water culture experiment result of Zhanjiang City, Guangdong
Illustrate: " control group " usefulness be the Environment of Litopenaeus vannamei Low mixed feed that does not add growth accelerator, " add growth accelerator group ": added 0.5% growth accelerator in the Environment of Litopenaeus vannamei Low mixed feed.
