Abstract

The invention provides a leech breeding method. The leech breeding method adopts special feed to feed leeches, wherein special feed A is prepared from fresh pear-shaped Bellamya, sucrose, soybean meal, earthworm liquid, green algae powder, gordon euryale seed powder and glossy privet fruit powder according to a certain proportion, and special feed B is prepared from fresh pear-shaped Bellamya, sucrose, soybean meal, earthworm liquid, agaric powder, root powder of kudzu vine and red konjic rice powder according to a certain proportion. According to the leech breeding method, nutrition requirements of the leech growth can be ensured, nutrients needed by the leeches can be supplemented in time, the growth of the leeches can be promoted, the survival rate and immunity of the leeches can be improved, so that the disease risk of the leeches is greatly reduced; therefore, the leech breeding method is low in cost, and has important economic benefits.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method for breeding leeches. technical background [0002] Leech, scientific name leech, is a kind of precious medicinal material. Many countries in the world have the habit of using leech as medicine since ancient times. Leech has the effect of expelling evil blood stasis and breaking blood accumulation, and is used to treat women's blood stasis, amenorrhea, hemorrhage in the uterus and other diseases. Today, the Chinese patent medicine made from leeches has been put into mass production, and the supply is in short supply. The annual domestic demand for dried leeches reaches thousands of tons. In recent years, with the extensive use of chemical fertilizers and pesticides, coupled with people's predatory capture of leeches, the resources of wild leeches are decreasing day by day, which is far from meeting the needs of the market. Therefore, the artificial breeding of ...
