Problems solved by technology

Both of the above two methods have the problems of long breeding period and high production cost, and the simple fasting treatment of cement pond culture has low efficiency in improving the antithrombin activity per unit mass of leech and the weight loss is large

Embodiment 1

[0061] A culture method for rapidly increasing the antithrombin activity of leeches, comprising the following steps: (1) seedling collection: collect the leech seedlings after hatching, and carry out separate seedling treatment after 20 days of concentrated seedling cultivation; They were fed daily at 22°C for 2 months, and gained weight rapidly; the breeding density was 60 fish / L, and the bait (fresh bovine serum) was fed once every 4 days with the bionic membrane as the medium, and the feeding time was selected at 12 am. Before: 00, leech is cleaned up before throwing something to feed, and feeds after draining water, and eating time is controlled at 30min; During leech feeding process, pick out the oversized individual at any time, to control its single food intake, prevent swelling and death; ( 3) Temperature control and fasting: the breeding temperature was controlled at 30° C., and the constant temperature was fasted for 1 month; (4) Harvesting. In addition, in the breed...

Embodiment 2

[0063] A culture method for rapidly increasing the antithrombin activity of leeches, comprising the following steps: (1) seedling collection: collect the leech seedlings after hatching, and carry out separate seedling treatment after 20 days of concentrated seedling cultivation; They were fed daily at 34°C for 2 months, and gained weight rapidly; the breeding density was 80 pigs / L, and the bait (fresh pig serum) was fed once every 4 days with the bionic membrane as the medium, and the feeding time was selected at 12 am. Before: 00:00, the leeches were cleaned before feeding, and the leeches were fed after draining the water, and the feeding time was controlled at 90 minutes; (3) temperature control and fasting: the feeding temperature was controlled at 30 ° C, and the constant temperature was fasted for 1 month; (4) Harvest . In addition, in the breeding process of steps (2) and (3), it is also necessary to clean and change water, that is, to wash and change once a day with cl...

Embodiment 3

[0065] A culture method for rapidly increasing the antithrombin activity of leeches, comprising the following steps: (1) seedling collection: collect the leech seedlings after hatching, and carry out separate seedling treatment after 20 days of concentrated seedling cultivation; (2) weight gain culture: add about 1 g The leech seedlings were fed daily at 30°C for 2 months, and gained weight rapidly; the breeding density was 75 tails / L, and the bait (celery juice with a volume ratio of 2:8) was fed once every 4 days with the bionic film as the medium. and bovine serum), the feeding time is selected before 12:00 in the morning, the leeches are cleaned before feeding, the water is filtered and fed, and the feeding time is controlled at 60 minutes; the leeches are picked out at any time during the feeding process. In order to control its single food intake and prevent bloating; after feeding, separate the leech from the feeding container, clean the leech and put it back in the feed...

Abstract

The invention discloses a breeding method for fast increasing the activity of antithrombase of leeches. The breeding method comprises the following steps of 1 young leech collection, 2 weight-increasing breeding, 3 temperature control and feed deprivation and 4 harvesting. The breeding method for fast increasing the activity of the antithrombase of the leeches is short in breeding period, the activity of the antithrombase with unit mass of the leeches can be fast improved in the short term, the activity of the antithrombase with unit mass of the leeches can be improved by 35.28% to 116.61% within one month, the medicinal value of the leeches is effectively improved, the temporary keeping time is shortened, production management cost is reduced, breeding risks are reduced, and therefore the economic benefits of breeding can be increased.

Description

technical field [0001] The invention relates to a breeding method for rapidly increasing the antithrombin activity of leeches, and specifically belongs to the technical field of leech breeding. Background technique [0002] Leech farming generally adopts two modes: planting leeches with water and drought alternately, field ridge and furrow culture and cement pond centralized culture. Field farming refers to the method of centralized breeding of seedlings in separate ponds after natural spawning and hatching or mixed breeding of parents and seedlings in the same pond. The operation steps are simple and easy to manage, but they are greatly affected by natural disasters. There are many natural enemies of leeches in the wild environment, and disease control is difficult. The breeding cycle is long and the density is low. After 1 to 2 years of field breeding, the fish will be caught directly. The individual weight gain rate of this model is very small, and the economic value is m...
