Preparation method of low-cost feed for freshwater shrimps

Abstract

The present invention discloses a preparation method of a low-cost feed for freshwater shrimps. The preparation method comprises the following steps: trace elements, vitamins, shrimp head powder, tryptophan, phenylalanine, medical stone powder, soybean oil and water are mixed evenly to obtain a premix; fish meal, laminaria japonica powder, earthworm powder, animal internal organs, sesame seed meal, semen euryales powder, lotus root starch, dried water hyacinth powder, high-gluten flour and the premix are mixed, the mixture is crushed, a moisture content is adjusted, the mixture is stirred evenly, steam is ventilated to conduct a curing, a compound binder is added, the materials are granulated and the granulated materials are cooled to obtain the low-cost feed for the freshwater shrimps. The provided preparation method of the low-cost feed for the freshwater shrimps is simple and convenient in method, and can effectively control costs of the feed, and the obtained feed for the freshwater shrimps is scientific and reasonable in formula, can meet needs of growth of the freshwater shrimps in each stage, effectively improves meat quality and nutrition value of the freshwater shrimps, and promotes the growth of the freshwater shrimps.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a method for preparing freshwater shrimp feed with low cost. Background technique [0002] In the ponds where the aquaculture industry in my country is mostly in a still water environment, high-density aquaculture causes a large amount of aquatic animal excrement, residual bait, disinfectant, etc. to settle on the bottom of the water, and then decomposes to release a large amount of harmful substances, which deteriorates the aquaculture water environment; With the increase of density, the deterioration of water body environment, and the aggravation of breeding diseases, many diseases have seriously threatened the breeding benefits, while the loss of feed in water and the accumulation of excreta have become the main pollution sources of water bodies, leading to the deterioration of water quality, the proliferation of pathogens, and the survival rate. decline. At present, the a...

[0002] In the ponds where the aquaculture industry in my country is mostly in a still water environment, high-density aquaculture causes a large amount of aquatic animal excrement, residual bait, disinfectant, etc. to settle on the bottom of the water, and then decomposes to release a large amount of harmful substances, which deteriorates the aquaculture water environment; With the increase of density, the deterioration of water body environment, and the aggravation of breeding diseases, many diseases have seriously threatened the breeding benefits, while the loss of feed in water and the accumulation of excreta have become the main pollution sources of water bodies, leading to the deterioration of water quality, the proliferation of pathogens, and the survival rate. decline

At present, in the process of freshwater shrimp farming, the amount of medicine is increased, and the water is changed frequently, which leads to an increase in the cost of farming, which needs to be solved urgently.
