Embodiment Construction

[0018] The normal feeding time of blood-sucking leeches is twice a week. In the past, there was no special time requirement for fishing, and they could be caught at any time. The hirudin content in the leeches caught by this method was unstable. The inventors found that after adopting the feeding method of the present invention, the content of hirudin can be stabilized and increased.

[0019] The method for improving the hirudin content in the leech body of the present invention is: to feed the leeches normally, the improvement is: 12 to 54 hours before fishing, feed the feed at least once; 54 hours to catch. Wherein, the feed used for normal feeding and supplementary feeding is animal blood; preferably vertebrate blood.

[0020] Animal blood is fresh animal blood, specifically animal blood collected on the same day and not coagulated. The use of fresh blood helps the leech to decompose and absorb, and can prevent the leech from getting sick or even dying due to blood deteri...

Abstract

The invention relates to the leech culture field, and in particular to a method for improving content of hirudin in a leech body aiming at a blood-sucking leech, which is mainly reflected on stabilizing and improving the content of the hirudin. The method for improving the content of the hirudin in the leech body is characterized in that: a leech is normally fed: the leech is fed again at least one time within 12h to 54h before being caught; or the leech is caught within 12h to 54h after being normally fed; and a feed for normally feeding and re-feeding of the leech is the blood of animals. By adopting the method, the content of the hirudin in the caught leech can be stabilized, and the content of the hirudin in the leech body can be remarkably improved.

Description

technical field [0001] The invention relates to the field of leech breeding, in particular to a method for improving the hirudin content in the body of blood-sucking leeches, which is embodied by increasing and stabilizing the hirudin content. Background technique [0002] Leeches are a general term for the class Hirrdinea of ​​the phylum Annelida, commonly known as leeches. There are about 500 species known in the world, divided into 4 orders. There are 2 orders, 8 families, 33 genera and nearly 100 species in my country. Chinese Pharmacopoeia (2010 Edition) records only three sources of leech medicinal materials: leech Whitmania pigra Whitman, leech Hirudo nipponica whitman or willow leaf leech Whitmania acranulata Whitman, wherein leech and willow leaf leech belong to non-blood-sucking leeches, and leech Hirudo nipponica whitman (also known as Japanese medical leeches) are blood-sucking leeches. In recent years, many scholars at home and abroad have carried out in-dept...
