Dried animal casing suitable for being fed to hematophagous medical leeches and processing method of dried animal casing

Abstract

The invention relates to a dried animal casing suitable for being fed to hematophagous medical leeches. The dried animal casing is processed from one of chitterlings, beef intestines or sheep intestines and can be fed to hematophagous leeches such as leeches, Poecilobdella manillensis and the like. The dried animal casing is processed by the steps of taking out casing layers from intestines of animals, soaking thoroughly washed small intestines of the animals into clean water, peeling grease, serous coats and fascia from outsides of intestinal canals, thoroughly flushing, putting the degreased casings into a clean water jar, repeatedly and continuously cleaning by hands so as to thoroughly remove swage and grease, forming by virtue of a mold, and finally carrying out blowing drying. By taking the dried animal casing as a feed material of the hematophagous leeches, the utilization rate of the feed is increased, the ingestion is improved, the growth is promoted, and residual feeds are reduced.

Description

technical field [0001] The invention relates to a blood-sucking leech feeding material, which belongs to the field of medicinal animal breeding. Background technique [0002] As a commonly used animal medicinal material, leech has anticoagulant and antithrombotic effects, and is a commonly used drug for promoting blood circulation and removing blood stasis. Although there are many kinds of medicinal leeches, they can be divided into blood-sucking leeches and non-blood-sucking leeches according to their feeding habits. Blood-sucking leeches mainly include related species of the order Arhynchobdellida and the family Hirudinidae recorded in "Chinese Animal History Hirudin Steel", mainly including Japanese Hirudonipponia and Poecilobdella manillensis, among which H. nipponia is recorded in the "Pharmacopoeia of the People's Republic of China", P. manillensis is the second volume of "Quality Standards for Zhuang Medicine of Guangxi Zhuang Autonomous Region" (2011 year edition). ...

AI Technical Summary

Problems solved by technology

[0004] The research on medicinal leeches mostly focuses on pharmacological effects, separation and extraction of anticoagulant substances, etc. There are relatively few researches on the breeding of this kind of blood-sucking medicinal leeches, especially in the choice of feeding methods, which seriously restricts The development of artificial breeding of medicinal leeches has been made. At present, the cultivation of many medicinal blood-sucking leeches mainly puts leeches directly into fresh blood. It has been reported that fresh cattle intestines, pig intestines, and sheep intestines are suitable for feeding blood-sucking leeches. Hello, our research group found that the commercially available dry pig casings can also be used as bait for medicinal blood-sucking leeches, but the cost of fresh animal original intestines is relatively high, and the materials are easy to rot after feeding, which has caused great damage to the environment. However, there are some chemical reagents in the processing process of commercially available pig dry casings, which are easy to cause damage to leeches after long-term feeding. Therefore, the above-mentioned existing materials for feeding do not fully meet the requirements of green ecological breeding, and a more suitable for leeches is needed.
