Live earthworm deodorized liquid protein leech feed and preparation method of the same

Abstract

The invention discloses a live earthworm deodorized liquid protein leech feed and a preparation method of the live earthworm deodorized liquid protein leech feed. The leech feed comprises the following raw materials in parts by weight: 70-80 parts of live earthworm, 50-70 parts of krill powder, 30-40 parts of feather powder, 12-18 parts of sesame meal, 2-3 parts of cream, 230-250 parts of radish juice, 12-16 parts of Sichuan pepper water, 7-8 parts of garlic sauce, 3-5 parts of citric acid, 2-3 parts of EM bacteria fermented liquid, 0.5-0.8 part of honey, 0.4-0.6 part of xylitan monostearate, 0.04-0.1 parts of natamycin and 220-280 parts of washing water of rice. The feed prepared by the invention uses earthworm protein as the principle raw material; the live earthworms are deodorized, so that the earthworm liquid protein with rich nutrients is obtained; the other raw materials are then assorted, so that the food calling force is increased. After eating the feed, the growth and the development of the leech are fastened, the culture cycle is shortened, the disease is reduced and the yield is improved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to a living earthworm deodorized liquid protein leech breeding feed and a preparation method thereof. Background technique [0002] Leeches, commonly known as leeches, are cold-blooded annelids that move very quickly. They can swim like waves and migrate like inchworms. It can grow and reproduce in both the north and the south of our country. It mainly lives in reservoirs, ditches, paddy fields, lakes and swamps in fresh water. It is most abundant in ponds rich in organic matter or in non-polluted rivers. It enters the dormant hibernation period in the soil at 3°C, and stings will emerge at temperatures above 8°C from March to April of the following year. Leech is a traditional special medicinal aquatic animal in my country. Its dried products can be used as medicine after brewing. It has the effects of treating stroke, high blood pressure, clearing ...

AI Technical Summary

Problems solved by technology

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 promotion of Chinese patent medicines, the demand for leeches is increasing year by year. However, the lack of wild leeches is far from enough To meet the huge supply demand in the market, artificial breeding is urgently needed to fill the huge supply gap in the market

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.
