Problems solved by technology

But at this time, the demand of Litopenaeus vannamei for vitamins (such as vitamin C, vitamin E, etc.) and mineral elements (calcium Ca, phosphorus P, etc.) will also increase or change in other ways.
However, the actual breeding process tells us that the conven

Abstract

The invention relates to the technical field of aquaculture feeds for litopenaeus vannamei, and in particular relates to a litopenaeus vannamei shell fixing additive premix and a preparation method of the litopenaeus vannamei shell fixing additive premix. The additive premix consists of multi-vitamins and composite mineral salts (based on the additive amount of feeds per ton). A plurality of special components are added, so that the symptom such as soft shell or failed shelling occurring in the process of shelling and fixing the shell of the litopenaeus vannamei can be effectively prevented. The additive amount of the additive premix in the litopenaeus vannamei feed accounts is 20 to 35kg, including 5 to 10kg of the vitamins, and 10 to 25kg of composite mineral salts. As the breeding test shown, the low-salinity additive premix for the litopenaeus vannamei can meet the demand of the litopenaeus vannamei to micronutrients in the shelling and shell changing period under the intensive cultivation mode, the breeding objects can grow quickly, the feed conversion rate is high, the immunity is improved, and the feed coefficient is 0.9 to 1.2.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a shell-solidifying additive premix for Litopenaeus vannamei. Background technique [0002] Litopenaeus vannamei, native to America. In recent years, the output of Litopenaeus vannamei has accounted for more than 90% of the total output of prawns in my country. According to statistics, in recent years, the output of Litopenaeus vannamei has accounted for more than 90% of the total output of prawns in my country. With the continuous pursuit of yield and growth rate, growth problems such as soft shell or failure to moult often occur in Litopenaeus vannamei culture. The emergence of these growth problems has an important relationship with the existing farming methods and feed formulation technology concepts. In the pursuit of growth speed, people often use the method of alternately injecting seawater and freshwater to accelerate the moulting and growth of Litopenaeus van...
