Abstract

The invention provides feed for culturing leeches and a preparation method of the feed. The feed for culturing the leeches is prepared from snail powder, freshwater mussel powder, blood powder, egg white, soybean meal, activin, rapeseed cakes, olive oil, potassium sulfate, potassium dihydrogen phosphate, sodium citrate, calcium lactate, calcium hydrophosphate, magnesium sulfate, potassium chloride, lentinan, chitosan, milkvetch root powder, radix salviae miltiorrhizae powder, garlic powder, sorbitol, compound microbial bacteria, complex vitamin, trace elements and an antioxidant. The feed is rich in nutritional ingredient, comprehensive in nutrient element, capable of effectively supplementing nutritional ingredients needed by leech growth, effectively promoting growth, shortening the leech growth cycle, reducing the culturing cost and increasing the economic benefit, free of pollution to a water body and friendly to the environment. The preparation method of the feed for culturing the leeches is simple and practicable in process, high in production efficiency, low in production and preparation cost, mild in preparation condition, easy to achieve, beneficial for market popularization and good in economic benefit.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a feed for cultivating leeches and a preparation method of the feed for cultivating leeches.

Problems solved by technology

At present, the existing common leech feed has single ingredients and lacks nutrients, which is not conducive to the growth and survival of leeches, and seriously affects the breeding benefits

In addition, the existing feeding feeds often lead to many leech diseases, low survival rate, slow growth rate, and the yield cannot be improved.

As for these common leech feeds, because they are taken from animals, they will more or less contain various parasites. If they are not handled properly, the leeches will affect their immunity after eating, and symptoms such as indigestion may occur. Affect its growth, seriously affect the survival rate of leech, seriously affect its medicinal value and economic value
