Abstract

The invention provides a feed for breeding crawfish in a rice field and a preparation method thereof. Raw materials of the feed comprises: corn flour, wheat, rapeseed meal, vital gluten, soya bean lecithin, konjaku flour, sodium alginate, chitosan, xanthan gum, fish oil, lysine, vitamin C, disodium succinate, citric acid, bacillus and nitrobacter. The preparation method of the feed comprises: firstly, adding the corn flour, the wheat, the rapeseed meal, the vital gluten and the konjaku flour into water; after carrying out heating and heat preservation, adding the sodium alginate and the xanthan gum, and carrying out heat preservation and stirring; after cooling, adding the soya bean lecithin, the chitosan, the fish oil, the vitamin C, the citric acid and the disodium succinate, and carrying out heating and heat preservation; after cooling, adding the bacillus and the nitrobacter, stirring and carrying out extrusion granulation to obtain the feed. According to the feed disclosed by the invention, not only is the immunity of the crawfish effectively reinforced, but also water body pollution caused by the feed can be effectively reduced, the survival rate of the crawfish is improved, and occurrence of diseases and insect pests is reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed for cultivating crayfish in paddy fields and a preparation method thereof. Background technique [0002] Breeding freshwater crayfish in paddy fields is a production method to improve the efficiency per unit area of ​​paddy fields, and can make full use of the shallow water environment and winter slack period of paddy fields. At present, there are mixed cropping, continuous cropping and crop rotation in paddy fields. According to production practice, mixed cropping and continuous cropping are often used in paddy field shrimp farming. This mode is that the rice and shrimp grow together in the same environment for a period of time. After the rice is harvested, the rice field is used as a shrimp pond during the idle period of the rice field, and the lobster continues to grow from May to June of the next year as a breeding cycle. [0003] The protein mass fraction...
