Turtle blood attractant leech culture liquid feed and preparation method thereof

Abstract

The invention discloses a turtle blood attractant leech culture liquid feed and a preparation method thereof. The liquid feed is prepared from the following raw materials in parts by weight: 40-50 parts of rotifer, 30-40 parts of water flea, 230-250 parts of bamboo leaf water, 50-70 parts of fish scale powder, 30-40 parts of soybean meal, 1-2 parts of butter, 2-3 parts of lactose, 3-4 parts of bunge pricklyash leaf powder, 2-3 parts of EM (effective microorganism) fermentation broth, 230-260 parts of bovine bone soup, 3-5 parts of turtle blood, 2-3 parts of sodium carboxymethylcellulose and 0.2-0.3 part of chlorogenic acid. The liquid feed is prepared by five continuous and orderly processes including homogenizing, cooking, fermenting, grinding and sterilizing. The feed is in a liquid state, is easy to eat by leech and rich in nutrition, and is beneficial to growth and development of leech; the fishy smell and eating taste of the feed are improved by adding the turtle blood and the bovine bone soup, so that the attractant capability of the liquid feed on leech is improved. By adopting the liquid feed, the growth and development of leech can be accelerated after leech eats the liquid feed, the culture cycle is shortened, diseases are reduced, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to a soft-shelled turtle blood-attracting leech breeding liquid 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.
