Blood-sucking leech larva complete formula feed and preparation method thereof

Abstract

The invention discloses a blood-sucking leech larva complete formula feed and a preparation method thereof, and belongs to the technical field of blood-sucking leech breeding feed preparation. The complete formula feed is prepared from, by weight, 0.1-20% of blood cell protein powder, 0.1-20% of plasma protein powder, 0.1-10% of animal fat, 0.001-0.1% of arginine, 0.01-5% of vitamin C, 0.001-0.1% of compound vitamin premix feed, 0.2-1.0% of sodium chloride and other raw materials. After being fully dissolved with deionized water, the raw materials are crushed for 5-60 minutes at the temperature of 30-70 DEG C by using ultrasonic waves, a pig casing is filled with the product, and the feed is obtained. Protein, fat, vitamin, inorganic salt and other nutrients in the blood-sucking leech larva complete formula feed are balanced in proportion, the feed formula and the preparation technology are scientific and reasonable, the method is simple and easy to implement, the prepared complete formula feed is good in flowability, has good food calling performance and palatability on blood-sucking leeches and is high in digestion and absorption efficiency, and the blood-sucking leeches fed with the feed are high in survival rate and high in growth speed.

Description

technical field [0001] The invention relates to a full-price compound feed for blood-sucking leech larvae and a preparation method thereof, belonging to the technical field of blood-sucking leech breeding feed preparation. Background technique [0002] Leech is a traditional Chinese medicinal material, its nature and taste are salty, bitter, flat; slightly poisonous. Return liver channel. It has the functions of dispelling blood and promoting menstrual flow, dispelling blood stasis, and is used for amenorrhea due to blood stasis, abdominal mass, stroke hemiplegia, and injury from falls; hirudin in leeches is the strongest specific inhibitor of thrombin found so far, and it is a blood-sucking medicine. The anticoagulant activity of leeches was significantly higher than that of non-blood-sucking leeches. In recent years, due to the environmental pollution of natural waters, its habitat has been continuously reduced, resulting in a decrease in its population and serious damag...

Problems solved by technology

Artificial breeding of leeches has alleviated the contradiction between supply and demand of leeches to a certain extent, but the traditional extensive field leech breeding mode has the problems of slow growth and low survival rate of larvae. Cultivating healthy leech seedlings is the key to industrialized high-density breeding of leeches. The essential

However, the current research on the cultivation of full-price compound f...
