Cream-flavored leech culture feed and preparation method thereof

Abstract

The invention discloses a cream-flavored leech culture feed and a preparation method thereof. The cream-flavored leech culture feed comprises the following raw materials in parts by weight: 150-170 parts of shrimp bran, 10-20 parts of Pu'er tea-leaf, 40-60 parts of fresh porcine blood, 70-80 parts of soybean meal, 30-40 parts of porcine bone marrow, 2-3 parts of yoghourt, 20-30 parts of rice washing water, 0.4-0.6 part of molasses, 0.2-0.3 part of a yeast extract, 0.1-0.2 part of EM zymocyte, 0.3-0.5 part of dairy salt, 3-5 parts of watery cream, 0.1-0.2 part of sucrose fatty acid ester and 0.4-0.6 part of glucose syrup. The end product is in the state of micro-powder, can be easily dissolved or suspended in water, can be adsorbed on sponge for feeding, is easy for ingestion and digestion in comparison with common large-particle-diameter feeds, and is easy to store and long in guarantee period.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to a creamy leech breeding feed and a preparation method thereof. Background technique [0002] Leeches, commonly known as leeches, are a kind of precious Chinese herbal medicines, which are recorded in many medical classics in ancient my country. It is recorded in the "Compendium of Materia Medica" of the Ming Dynasty: water frogs "mainly drive away bad blood, trace blood, moon closure, and accumulate under broken blood. Childless, Lishuitong...heals wounds, falls, and animal blood." Modern medical research shows that leech salivary glands contain an anti-coagulant substance—hirudin, which can be widely used in medical fields such as replantation of severed limbs and inhibition of cancer cell growth. With the application and improvement of modern biotechnology, the extraction and processing of hirudin and the clinical application of medicine, as well...

AI Technical Summary

Problems solved by technology

Judging from the currently mastered leech breeding technology, the current leech farming mainly uses animal blood, earthworms, snails, river mussels, etc. as edible feed. These feeds are not processed to a high degree, and the absorption and utilization efficiency of nutrients is low. The breeding cycle is long, the growth is not good, and it is easy to lead to the occurrence of disease and death

Due to the lack of suitable feed, the quality and output of leech cultivation have been greatly affected. Therefore, it is urgent to develop a leech feed with high breeding efficiency and high added value.
