Liquid leech suckling feed developed from small coarse fishes and preparation method of the liquid leech suckling feed developed from small coarse fishes

Abstract

The invention discloses a liquid leech suckling feed developed from small coarse fishes and a preparation method of the liquid leech suckling feed developed from small coarse fishes. The feed comprises the following raw materials in parts by weight: 80-90 parts of small coarse fishes, 3-4 parts of formic acid, 50-70 parts of corn powder, 40-50 parts of duck blood, 30-40 parts of vinegar residues, 18-26 parts of minced pumpkin, 1-2 parts of butter, 2-3 parts of EM bacteria fermented liquid, 260-280 parts of bean sprouts soaking water, 1-2 parts of sesame sauce, 2-5 parts of egg white, 0.2-0.4 part of glyceryl monostearate and 0.1-0.2 part of sodium lactate. The feed of the invention is in the state of liquid which has better palatability than solid feed, so that the feed is very convenient for leech, especially young leech, to eat by suckling; thus, the feed is high in utilization ratio. The feed has an egg smell and a sesame flavor, so that the feed is more attractive to the leech; after eating the feed, the growth and the development of the leech are fastened, the culture cycle is shortened, the growth vigour is extremely good, the leech is not easy to get sick and the culture quality and the yield of the cultivation are greatly improved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to a liquid leech sucking feed developed from small miscellaneous fish 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, cleari...

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.
