Problems solved by technology

But at this time, Litopenaeus vannamei has little requirement for protein, fat, sugar, vitamins (such as vitamin C, vitamin D, etc.), mineral elements (calcium Ca, phosphorus P, etc.) and other ingredients that help to solidify the shell. There will be growth or other changes
The actual breeding process tells us that the conventional feed cannot meet the nutritional needs of this special growth period of Litopenaeus vannamei

Abstract

The invention discloses a composite shell strengthening additive for litopenaeus vannamei and a preparation method thereof. The composite shell strengthening additive for the litopenaeus vannamei is characterized by being prepared by, by weight, monocalcium phosphate 60%-70%, astaxanthin 2.3%-3%, cholesterol 5%-10%, phosphate 12%-16% containing 35% of vitamin C, vitamin D 31%-2%, vitamin E 3%-4% and beta-glucan 9%-10%. A chemical name of the astaxanthin is 3,3'-dyhydroxyl-4,4'-diketo-beta,beta'-carotene, and a molecular formula is C40H52O4. The preparation method comprises the steps of weighing ingredients by weight percentage, respectively smashing the ingredients and placing the ingredients into a mixing machine to be evenly mixed, wherein the monocalcium phosphate is added first and then other ingredients are further added in succession. By means of the composite shell strengthening additive for the litopenaeus vannamei and the preparation method, the problems including soft shells, shell shedding failure, unsmooth shell strengthening and the like are effectively solved in the litopenaeus vannamei breeding process, the self immunocompetence of the litopenaeus vannamei is improved, the additive has no any harmful effect on palatability of feeds, raw material ingredient sources are stable, the price is low, and the additive has good application prospect.

Description

technical field [0001] The invention relates to a feed additive, in particular to a composite shell-solid additive for Litopenaeus vannamei and a preparation method thereof. The invention belongs to the technical field of artificial cultivation of Litopenaeus vannamei. Background technique [0002] Shrimp farming is the pillar industry of my country's aquaculture industry. The vannamei prawn (Litopenaeus vannamei), native to the Americas, has quickly become an upstart in the aquaculture industry due to its large output, high meat yield, ease of intensive farming, and delicious meat. It ranks first in the world's shrimp production. According to market research, growth problems such as soft shell or failure to moult often occur in Litopenaeus vannamei culture. According to analysis, the emergence of these growth problems has an important relationship with the existing breeding methods and feed formula composition. In the pursuit of growth speed, people often use the method...
