Fresh pig blood smell removing fermented leech culturing feed and preparation method thereof

Abstract

The present invention discloses a fresh pig blood smell removing fermented leech culturing feed and a preparation method thereof. The feed comprises the following raw materials in parts by weight: 150-170 parts of corn powder, 70-90 parts of fresh pig blood, 40-60 parts of wheat bran, 20-30 parts of bamboo leaf powder, 50-70 parts of black bean powder, 10-20 parts carrot powder, 2-3 parts of yogurt, 40-50 parts of steamed fish powder, 2-3 parts of cattle bone meal, 1-2 parts of curry sauce, 20-30 parts of rice washing water, 0.4-0.6 part of molasses, 0.1-0.2 part of egg yolk powder, and 0.1-0.2 part of EM fermentative bacterium. The finished products of the fresh pig blood smell removing fermented leech culturing feed are in micro powder states, are easily dissolved or suspended in water, can be adsorbed onto sponges to conduct feeding, are easier to be taken and digested than the feed of ordinary big grain sizes, and are easy for storage, and long in shelf life.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to fresh pig blood fermented 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 ...

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.
