Oyster oil feeding promoting liquid leech sucking feed and preparation method thereof

Abstract

The present invention discloses an oyster oil feeding promoting liquid leech sucking feed and a preparation method thereof. The feed comprises the following raw materials in parts by weight: macrobrachium superbum 70-80 parts, crabs 50-60 parts, maltodextrin 20-30 parts, minced oolong tea 1-2 parts, rice koji 2-3 parts, flaxseed meal 30-40 parts, lees 20-30 parts, corn flour 30-40 parts, earthworm protein powder 30-40 parts, fish blood 3-4 parts, EM zymophyte fermentation liquid 2-3 parts, ziziphus jujuba flower extract water 260-280 parts, oyster oil 2-3 parts, sodium caseinate 0.05-0.1 part, and sodium dehydroacetate 0.05-0.1 part. The feed is in a liquid state, is very easy for the sucking consumption of leeches, especially young leeches, thus is higher in utilization rate, has a delicious and fragrant smell of the oyster oil and a stronger attractant for leeches, can accelerate growth and development after the consumption of leeches, and shortens culturing cycles. Leeches fed by the feed are very good in growth trends and are not easily to get sick, and the quality and output of the culturing are significantly increased.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to an oyster oil food-promoting liquid leech sucking 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 blood stas...

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.
