Embodiment 1

[0014] Add 50g of agar powder into 400mL of boiled distilled water, stir to dissolve the agar powder completely, then add 150g of fresh river snail meat, 300g of fresh apple snail meat, and 100g of fresh scallop mantle, and keep the temperature of the mixture at 60°C; Fully stir for 10 minutes with a high-speed homogenizer, pour into a mold of 2 cm x 2 cm x 3 cm, and cool at room temperature to obtain the special feed for wide-body golden leeches. The feed can maintain a solid form in water for 10 hours, and can replace 52% of live snails without reducing the growth rate of the leech.

Embodiment 2

[0016] Add 30g of agar powder into 300mL of boiled distilled water, stir to dissolve the agar powder completely, then add 250g of fresh snail meat, 370g of fresh apple snail meat, and 50g of fresh scallop mantle, and keep the temperature of the mixture at 60°C; Fully stir for 10 minutes with a high-speed homogenizer, pour into a mold of 2 cm x 2 cm x 3 cm, and cool at room temperature to obtain the special feed for wide-body golden leeches. The feed can maintain a solid form in water for 8 hours, and can replace 60% of live snails without reducing the growth rate of the leech.

Abstract

The invention discloses special feed for breeding whitmania pigra and a preparation method of the special feed. The special feed is prepared from the following raw materials in parts by mass: 15 to 25 parts of fresh field snail meat, 30 to 40 parts of fresh pomacea canaliculata meat, 5 to 10 parts of fresh scallop pallium, 3 to 5 parts of agar powder and 30 to 40 parts of distilled water. The preparation method comprises the following steps: firstly, adding the agar powder into the boiling distilled water, stirring to enable the agar powder to be fully dissolved, and then adding the fresh field snail meat, the fresh pomacea canaliculata meat and the fresh scallop pallium, and enabling the temperature of a mixture not to be lower than 50 DEG C; secondly, sufficiently crushing a mixture by a high-speed homogenizer, and then pouring the crushed material into a mold with a proper size and cooling at room temperature, thus obtaining the special feed for the whitmania pigra. The special feed for the whitmania pigra, disclosed by the invention, has the advantages that a solid form of the feed can be kept in water for 8 to 10 hours, and 50 to 60 percent of live freshwater snail can be replaced in the breeding process of the whitmania pigra.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a special feed for cultivating wide-body golden leeches and a preparation method thereof. Background technique [0002] Wide-bodied golden leeches, common names, leeches, horse turtles, belong to the phylum Annelida, class Hirudophylum, order Hirudophyllidae, family Hirudidae, and grow and reproduce in inland freshwater waters. The wide-bodied golden leech contains hirudin, which can delay and hinder blood coagulation, thereby having an anticoagulant effect. It is often used in the prevention and treatment of cardiovascular and cerebrovascular diseases, and the market demand is huge. [0003] The wide-bodied golden leech mainly feeds on live snails. Due to the limited number and unstable supply of live snails, the large-scale breeding of wide-bodied golden leech is seriously restricted. In order to promote the large-scale cultivation of leeches wide-bodied, it is urgent to develop a s...
