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
