Embodiment 1

[0036] Dissolve 3 parts of sodium chloride in water, mix well to obtain sodium chloride solution;

[0037] Dissolve 5 parts of gluconolactone in water, mix well to obtain gluconolactone solution;

[0038] Take 100 parts of fresh blood, add sodium chloride solution and gluconolactone solution while stirring.

Embodiment 2

[0040] Dissolve 13 parts of sodium chloride in water, mix well to obtain sodium chloride solution;

[0041] Dissolve 7 parts of gluconolactone in water, and mix uniformly to obtain a gluconolactone solution;

[0042] Take 100 parts of fresh blood, add sodium chloride solution and gluconolactone solution while stirring.

Embodiment 3

[0044] 19 parts of sodium chloride were dissolved in water, and mixed uniformly to obtain a sodium chloride solution;

[0045] Dissolve 9 parts of gluconolactone in water, and mix uniformly to obtain a gluconolactone solution;

[0046] Take 100 parts of fresh blood, add sodium chloride solution and gluconolactone solution while stirring.

[0047] The leech feed obtained in Examples 1-3 of the present invention and ordinary fresh pig blood were fed in the same feeding and management manner to the four groups of leeches for 5 months. Compared with the comparative example, the cultured survival rate of the comparative example is 73%, while the cultured survival rate of Examples 1 to 3 can reach more than 90%. powerful.

[0048] To sum up, the palatability of feeding leeches with this feed is better, the leeches digest well, and the meat conversion rate is high. Due to the good digestion and absorption, the disease resistance of leeches is naturally enhanced, which solves the pr...

Abstract

The invention discloses leech feed and a preparation method thereof. By adding glucolactone to fresh blood, blood can be rapidly solidified without being coagulated, and meanwhile the oxidation speed of blood is decreased. The leech feed prepared in this way is better in leech feeding palatability, is beneficial to adult leech feeding, leaches can well digest the feed, the feed-to-meat conversion rate is high, and the problems that because the blood coagulation and oxidation are quick and the plasma feeding time is short, the utilization rate is low and waste is severe are solved.

Description

technical field [0001] The invention relates to the field of leech feed preparation, in particular to a leech 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 as the development, development and promot...
