Medicinal selenium-rich leech culturing liquid feed and preparation method thereof

Abstract

The present invention discloses a medicinal selenium-rich leech culturing liquid feed and a preparation method thereof. The feed comprises the following raw materials in parts by weight: water fleas 50-60 parts, blood worms 70-80 parts, rice koji 2-3 parts, rose petals 5-7 parts, corn starch 20-30 parts, blood meal 40-50 parts, sunflower seed meal 30-40 parts, oil-fried chicken skin 7-9 parts, wafer biscuit crumbs 14-18 parts, squid oil 1-2 parts, EM zymophyte fermentation liquid 2-3 parts, selenium-rich yeast fermentation liquid 300-400 parts, tripolyglycerol monostearate 0.4-0.8 part, and calcium propionate 0.1-0.2 part. The feed is in a liquid state, is more palatable than solid feed, is very easy for the sucking consumption of leeches, especially young leeches, thus is higher in utilization rate, is fishy and fragrant in smell, is 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 a medicinal selenium-enriched leech culture liquid feed and a preparation method thereof. Background technique [0002] Leeches, commonly known as leeches, are cold-blooded annelids. They are very agile, can swim in waves, and can also migrate as inchworms. It can grow and reproduce in the north and south of my country. It mainly lives in freshwater reservoirs, ditches, paddy fields, lakes and swamps. At 3 ℃, it enters the hibernation period of dormancy in the soil, and the stinging activity occurs when the temperature is higher than 8 ℃ in March-April of the following year. Leech is a traditional special medicinal aquatic animal in my country. Its dried product can be used as medicine after being brewed, and has the effect of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injury. Fresh leech saliva contains...

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.
