Problems solved by technology

[0004] The research on medicinal leeches such as Japanese medical leeches H.nipponia and Philippine leech P.manillensis is mostly focused on pharmacological effects, separation and extraction of anticoagulant substances, etc. The research on the breeding of such blood-sucking medicinal leeches is still relatively low. Fewer, especially the choice of feeding methods, seriously restricts the development of medicinal leech artificial breeding. At present, the breeding of many medicinal blood-sucking leeches mainly puts leeches directly into fresh blood, or uses blood clots for leeches to suck. , but according to our research, this feeding method does not conform to the physiological characteristics of blood-sucking medicinal leeches, and the food intake is small and the growth is slow

Embodiment 1

[0018] 1. Materials: Dried pigs sold in the market, the dried pig casings have a diameter of 42mm and a single layer thickness, and the dried pig casings have no leakage points;

[0019] 2. According to the food intake requirement of feeding leeches, cut the dried pig casings to a length of 50cm, and tie one end with a thin thread to ensure no leakage;

[0020] 3. Pour the fresh blood (serum) into the spliced ​​dried pig casings, and tie up the filling mouth to ensure no leakage;

[0021] 4. Put the dry pig casings containing the leech phenanthrene bait——fresh blood (serum) into the leech breeding pond, and feed the leeches every two days for 30 minutes each time. The weight of the bait each time is 100% of the body weight of the leeches before feeding.

[0022] Control group 1: Dried pig casings have a diameter of 42 mm and a thickness of four layers. The dried pig casings have no leakage points. According to the feed intake requirements of leeches, the dried pig casings are...

Embodiment 2

[0024] 1. Materials: dried pigs sold in the market, the diameter of dried pig casings is 38mm, the thickness is double-layered, and the dried pig casings have no leakage points;

[0025] 2. According to the food intake requirement of feeding leeches, cut the dried pig casings to a length of 100cm, and tie one end with a thin thread to ensure no leakage;

[0026] 3. Pour the fresh blood (serum) into the spliced ​​dried pig casings, and tie up the filling mouth to ensure no leakage;

[0027] 4. Put the dry pig casings containing the leech phenanthrene bait——fresh blood (serum) into the leech breeding pond for the leeches to feed on. Every 4 days, each feeding is 60 minutes, and the weight of the bait is fed each time. 100% of the body weight of the leeches before feeding.

[0028] Control group 2: The dried pig casings sold in the market have a diameter of 38 mm and double thickness, and there is no leakage point in the dried pig casings; the dried pig casings are cut into leng...

Embodiment 3

[0030] 1. Materials: Dried pigs sold in the market, the diameter of the dried pig casings is 38mm, the thickness is single layer, and the dried pig casings have no leakage points;

[0031] 2. According to the food intake requirement of Japanese medical leeches, cut the dried pig casings to a length of 20cm, and tie one end with a thin wire to ensure no leakage;

[0032] 3. Pour Japanese medical leech bait - fresh blood (serum) into the spliced ​​dried pig casings, and tie up the filling mouth to ensure no leakage;

[0033] 4. Put the dried pig casings containing Japanese medical leech bait——fresh blood (serum) into the leech breeding pond for the leeches to feed on. Every 8 days, each feeding is 60 minutes, and the weight of the bait is fed each time. 100% of the body weight of the leeches before feeding.

[0034] Control group 3: The dried pig casings sold in the market have a diameter of 38 mm and a single layer thickness, and there is no leakage point in the dried pig casi...

Abstract

A medicinal blood-sucking leech bait feeding method is characterized in that the dried pig casings sold in the market without leakage points are taken, and the dried pig casings are spliced ​​into lengths of 10-400 cm according to the feed intake requirements of the leeches, and one end of the casing is Bundle with thin wire to ensure no leakage, then pour the leech bait—fresh blood or serum into the spliced ​​pig dry casing, and tie the filling mouth to ensure no leakage, and finally put the leech bait—fresh The dried pig casings with blood or serum are put into the leech breeding pond for the leeches to suck. In addition, the price of raw materials is low, the source is stable, and the production process is simple.

Description

technical field [0001] The invention relates to a method for feeding blood-sucking leeches, belonging to the field of medicinal animal breeding. Background technique [0002] Leech, which has been recorded in "Shen Nong's Materia Medica", has high medicinal value; it grows and reproduces in inland freshwater waters, and is a traditional Chinese special medicinal aquatic animal. Stroke, high blood pressure, amenorrhea, bruises and other effects. Modern studies have shown that leech preparations have special effects in preventing and treating cardiovascular and cerebrovascular diseases and cancer. Historically, it was mainly caught by natural fishing. However, due to the abuse of pesticides and fertilizers in recent years, and the pollution of the environment by the "three wastes" of industry and agriculture, wild natural resources have declined sharply. With the in-depth development of the medicinal value of leeches, its market demand potential huge. [0003] Leeches can b...
