Embodiment Construction

[0030] The special feed for cultivating blood-sucking leech larvae is prepared by mixing plasma protein powder, sodium chloride, multivitamins, sodium vitamin C, compound minerals, lidocaine, and Sanhuang powder according to the following weight percentages:

[0031] Plasma protein powder 85.7%;

[0032] Sodium chloride 6.4%;

[0033] Multivitamin 1.4%;

[0034] Sodium vitamin C 0.7%;

[0035] Complex Minerals 1.4%;

[0036] Lidozyme 2.2%;

[0037] Sanhuang powder 2.2%.

[0038] The method of using the special feed for the cultivation of blood-sucking leech larvae: Accurately weigh 14 grams of the finished premixed feed of the above invention, dissolve it in 1 liter of pure water preheated to 37°C (which is conducive to fully dissolving the raw materials), and fully stir to dissolve; The prepared bait nutrient solution is quickly poured into commercialized fresh pig small intestine casings (products of Baoding Tiantai Casing Food Co., Ltd., which have undergone strict ste...

Abstract

The invention relates to a special feed for culturing blood-sucking leech larvae and belongs to the technical field of preparation of a leech larva culturing feed. The special feed for culturing the blood-sucking leech larvae is prepared from the raw materials of plasma protein powder, composite vitamin powder, vitamin C, composite mineral substances, a Lido enzyme, tri-yellow powder and the like. According to the invention, Chinese herbal medicine tri-yellow powder is adopted to replace common antibiotics in the conventional cultivation, so that the drug residue of blood-sucking leeches is eliminated and the quality of a leech medicinal material is improved. The feed has low preparation cost, high biological safety coefficient and is easy to digest and adsorb by the leech larvae; symptoms such as indigestion caused by feeding of a conventional feed, hematemesis, physical disfigurement or swelling caused by bacteria infection and the like are avoided; the special feed is very beneficial to industrial large-scale reproduction and cultivation of the leeches; and the gap that in China, no special feed for cultivating the leech larvae is filled. By the practical test of continuously feeding for five years, the growth rate and the survival rate of the leech larvae are greatly improved, the leech yield is high, no pesticide is left and the prepared leech medicinal material has high quality.

Description

technical field [0001] The invention relates to a special feed for cultivating blood-sucking leech larvae, belonging to the technical field of feed preparation for cultivating leech larvae. Background technique [0002] As a traditional Chinese medicine, leech is mainly used to treat cardiovascular and cerebrovascular diseases. The hirudin contained in blood-sucking leeches is the strongest natural inhibitor of antithrombin among the known anticoagulant substances found in the world so far. It is very effective in dilating blood vessels, reducing blood viscosity, and increasing blood circulation. At present, due to the high incidence of cardiovascular and cerebrovascular diseases, the demand for leeches, especially blood-sucking leeches, is increasing. my country's wild leeches are mainly produced in Hubei, Hunan, Shandong, Henan, Jiangsu, Guangdong, Guangxi, and Hainan provinces. However, since the 1980s, due to the extensive use of pesticides and fertilizers, wild leeches...
