Problems solved by technology

With the development of the aquaculture industry, the types of artificial breeding have increased, the scope of cultivation has expanded, and the types of cultivation have continued to increase. There are also huge differences in the requirements for feed properties. The feeding method is sucking ingestion, and through trial feeding with a large amount of feed, leeches are very selective about the hardness and softness of the feed, and only ingest it when it can suck, but there is no such feed for leeches to choose on the market

Embodiment

[0028] Production steps of the present invention are as follows:

[0029] (1) Raw material preparation and drying: Dry the fishmeal and its raw materials that need to be dried in a relatively wide open space, preferably in the shade, until dry and easy to crush and not agglomerated. In particular, fishmeal and soybean meal contain salt (it is best to use no salt), which is easy to absorb water and regain moisture, and still needs to be dried after purchase. (the required raw materials of the present invention: fish meal, shell powder, soybean meal, starch, yeast, chitosan and colloidal protein etc. can all be purchased commercially on the market, without special requirements, purchase with high quality and low price as a criterion.

[0030] (2) Early cleaning: The purpose of early cleaning is to remove impurities and sediment in raw materials after drying.

[0031] (3) Pulverization: The material after the initial cleaning, as well as shell powder, soybean meal, starch, yeast...

Abstract

The invention discloses a sucking feed for leeches, which relates to the technical field of feedstuff. The sucking feed is prepared from the following components in percentage by weight: 55-80% of fishmeal, 5-15% of conch meal, 5-10% of soymeal, 1-5% of germ meal, 3-5% of blood meal, 1-5% of yeast and 1-2% of chitosan and colloid protein. The preparation method comprises the following steps: preparing raw materials, tedding, preliminary cleaning, grinding and mixing. The sucking feed provided by the invention significantly improves the feeding strength of leeches, promotes the growth of leeches, improves the yield of leeches and the survival rate of young leeches, improves the utilization rate of the feed, improves intestinal micro environment of the leeches, stimulates the leech bodies to emerge strong immune and stress response and improves the immunity and quality of the leeches.

Description

Technical field: [0001] The invention relates to the technical field of feed, in particular to a feeding animal-leech special feed and a production method thereof. Background technique: [0002] Leeches are relatively ancient lower animals on earth. According to the analysis of amber fossils embedded with leech remains picked up from the coast of the Baltic Sea, leeches have a history of at least 40 to 50 million years. [0003] Leeches belong to the phylum Annelida, class Hirudophylum, order Hirudognathus, and family Hirudoceae. The genus includes 4 orders, namely the genus, the genus, the mandibular, and the pharynx. The following mainly introduces the genus. [0004] Gnathobdellidae (Gnathobdellidae) animals do not have a retractable snout, the pharynx is fixed, and there are three jaw plates in the mouth. There is no true vascular system in the body, replaced by the hemocoelomous system. The blood coelom is red with grape-like tissue. The reproductive system is rela...
