Feed special for high-yield and high-quality leeches

Abstract

The invention discloses a feed special for high-yield and high-quality leeches. The feed is prepared from, by weight, 20-35 parts of fish meal, 5-15 parts of acetes chinensis, 20-40 parts of animal blood, 20-30 parts of earthworms, 5-15 parts of snails, 5-12 parts of freshwater mussels, 5-15 parts of puffed peanut meal, 5-15 parts of pregelatinized corn starch, 20-40 parts of millet, 2-8 parts of cottonseed cake, 2-10 parts of fermented biological protein, 1-10 parts of brewer's grain, 1-3 parts of kelp powder, 2-15 parts of modified gelatin, 1-6 parts of deep sea fish oil, 2-8 parts of corn oil, 1-5 parts of grape seed oil, 1-2 parts of soybean phospholipid, 1-2 parts of betaine, 0.01-0.06 part of composite trace elements, 0.2-0.8 part of vitamins, 0.2-1 part of mineral salt and 1-3 parts of EM bacterial solution. The feed can provide adequate balanced protein and energy for the leeches, effectively promote leech growth and improve the digestion and absorption rate and can improve the disease immunity of leeches.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed for high-yield and high-quality leeches. 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 the north and south of our country, and mainly lives in reservoirs, ditches, paddy fields, lakes and swamps in fresh water, and it is most abundant in ponds rich in organic matter or in small rivers without pollution. 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 stasis, amenorrhea, and traumatic injuries. Fresh leech saliva contains a polypeptide called hirudin, which has anticoagulant effect, can prevent the action of thrombin on fibrin, hinder blood coagulation, can resist t...

Problems solved by technology

With the application and improvement of modern biotechnology, the demand for leeches is increasing year by year. However, the shortage of wild leeches is far from being able to meet the huge supply demand in the market. Therefore, artificial breeding is urgently needed to fill the huge supply gap in the market.

Judging from the currently mastered leech breeding technology, the absorption and utilization efficiency of leech breeding feed at this stage is low, the leeches grow slowly, the breeding cycle is long, the growth is not good, and it is easy to cause disease and death.

Due to the lack of suitable feed, the quality and production of leech farming have been greatly affected
