Embodiment 1

[0011] Example 1: This leech bait includes casings and contents. The contents consist of fish meal, shell meal, snail meal, earthworm meal, animal blood, bran and soybean meal in a ratio of 3:3:3:3:3:2 : Mix it at a ratio of 2 and put it into the casing, tie both ends of the casing tightly, and put it into the breeding pond. The amount of feed is 0.5kg of this leech bait per 10,000 philippines. The cultivated philippines leeches were sampled and inspected: the average total dry ash was 4.76%, the average acid-insoluble ash was 0.76%, the pH was 6.9, the average extract was 8.8%, and the average antithrombin activity per 1g was 434.1 U.

Embodiment 2

[0012] Example 2: This leech bait includes casings and contents. The contents consist of fish meal, shell meal, snail meal, earthworm meal, animal blood, bran and soybean meal in a ratio of 5:5:5:5:5:3 : Mix it at a ratio of 3 and put it into the casing, tie the ends of the casing tightly, and put it into the breeding pond. The amount of feed is 0.6kg of this leech bait per 10,000 philippines. The cultivated philippines leeches were sampled and inspected: the average dry ash content was 4.73%, the acid-insoluble ash content was 0.78%, the pH was 6.5, the extract was 8.9%, and the antithrombin activity per 1g was 446.5 on average.

Abstract

The invention discloses leech bait and relates to the technical field of hirudiniculture. The leech bait is prepared from a sausage casing and contents, wherein the contents are prepared from the following raw materials in parts by weight: 3 to 5 parts of fish meal, 3 to 5 parts of shell powder, 3 to 5 parts of snail powder, 3 to 5 parts of earthworm powder, 3 to 5 parts of animal blood, 2 to 3 parts of bran and 2 to 3 parts of soya bean meal. The leech bait disclosed by the invention can meet a growth nutrition requirement of poecilobdella manillensis, cultivated poecilobdella manillensis hasgood quality, dry body total ash is lower than 4.8%, acid-insoluble ash is lower than 0.8%, a pH value is 5.6 to 7.3, extractum is larger than 8.7%, and activity of antithrombase contained in every 1g of the cultivated poecilobdella manillensis is higher than 431.0U.

Description

Technical field [0001] The invention relates to the technical field of leech breeding, in particular to a leech bait. Background technique [0002] Phnom Penh Lech, Hirudinidae Poecilobdellamanillensis, is a characteristic medicinal animal resource in Guangxi. The natural hirudin secreted by the salivary glands of Hirudinidae is the strongest natural antithrombin substance among the known substances found in the world so far. It has a very high curative effect on the treatment of cardiovascular and cerebrovascular diseases, especially cerebral apoplexy. In recent years, with the rapid increase in global demand for leeches, artificial indiscriminate catching has gradually depleted natural resources and a serious imbalance between supply and demand. Guangxi is one of the few suitable places for Filipino leeches in the country, and it is uniquely endowed with the development of breeding conditions. However, at present, the domestic artificial breeding of Philippine cow leeches is ...
