Embodiment 1

[0021] A culture method for rapidly increasing the antithrombin activity of Japanese medicine leech is carried out according to the following steps:

[0022] S1: The setting of the breeding water tank, the length of the breeding water tank is 100cm, the width of the breeding water tank is 40cm, the height of the breeding water tank is 30cm, the water temperature in the water tank is controlled at 17°C, and the water level in the water tank is controlled at 1cm ;

[0023] S2: For seedling cultivation of Japanese leech, select Japanese leech seedlings with a weight of 0.5g / piece, and put the selected Japanese leech seedlings into the breeding tank at a density of 1000-1200 / square meter;

[0024] S3: Feed preparation, take the bait without adding anticoagulant and preservative, filter the bait with a 120-150 mesh filter, take the filtered plasma, and then put the plasma into artificial casing or pig small intestine , use cotton thread to tie up each section according to the leng...

Embodiment 2

[0034] A culture method for rapidly increasing the antithrombin activity of Japanese medicine leech is carried out according to the following steps:

[0036] S2: For seedling cultivation of Japanese leech, select Japanese leech seedlings with a weight of 0.5g / piece, and put the selected Japanese leech seedlings into the breeding tank at a density of 1000-1200 / square meter;

[0037] S3: Feed preparation, take the bait without adding anticoagulant and preservative, filter the bait with a 120-150 mesh filter, take the filtered plasma, and then put the plasma into artificial casing or pig small intestine , use cotton thread to tie up each section according to the leng...

Embodiment 3

[0047] A culture method for rapidly increasing the antithrombin activity of Japanese medicine leech is carried out according to the following steps:

[0048] S1: The setting of the breeding water tank, the length of the breeding water tank is 150cm, the width of the breeding water tank is 50cm, the height of the breeding water tank is 35cm, the water temperature in the water tank is controlled at 19°C, and the water level in the water tank is controlled at 2cm ;

[0049] S2: For seedling cultivation of Japanese leech, select Japanese leech seedlings with a weight of 0.5g / piece, and put the selected Japanese leech seedlings into the breeding tank at a density of 1000-1200 / square meter;

[0050] S3: Feed preparation, take the bait without adding anticoagulant and preservative, filter the bait with a 120-150 mesh filter, take the filtered plasma, and then put the plasma into artificial casing or pig small intestine , use cotton thread to tie up each section according to the leng...

Abstract

The invention relates to the technical field of hirudo nipponia culture, in particular to a culture method for rapidly increasing antithrombin activity of hirudo nipponia. The culture method comprisesthe following steps that S1, a breeding water tank is arranged, wherein the length of the breeding water tank ranges from 100 cm to 200 cm, the width of the breeding water tank ranges from 40 cm to 60 cm, the height of the breeding water tank ranges from 30 cm to 40 cm, the water temperature in the water tank is controlled to range from 17 DEG C to 20 DEG C, and the water level in the water tankis controlled to range from 1 cm to 3 cm; S2, breeding seedlings of the hirudo nipponia; S3, conducting feed preparation; S4, feeding feed; and S5, conducting water quality management. The invention aims to provide the culture method for rapidly increasing the antithrombin activity of the hirudo nipponia. The culture method is used for solving the problems of low survival rate and low antithrombinactivity efficiency of the hirudo nipponia in the prior art.

Description

technical field [0001] The invention relates to the technical field of Japanese leech breeding, in particular to a breeding method for rapidly increasing the antithrombin activity of Japanese leech. Background technique [0002] Japanese medical leech (scientific name: Hirudo nipponia) is an animal of the genus Hirudo in the family Hirudoceae. Distributed in Japan, the Far East of Russia, Mongolia, and the northeastern provinces of mainland China, Inner Mongolia, west to Sichuan, Gansu, south to Guangdong and other places, generally inhabit paddy fields and their connected ditches, ponds and swamps and In particular, retting fields and farmland fields with perennial water accumulation or poor drainage have the largest number. Japanese medical leech is the only blood-sucking leech species recorded in the "Chinese Pharmacopoeia". Japanese medical leeches have unique curative effects in promoting blood circulation, removing blood stasis, promoting menstrual flow, and anti-can...
