Production method of immunocompetence feed for river crabs

Abstract

The invention discloses a production method of an immunocompetence feed for river crabs. The immunocompetence feed for river crabs contains the special bioactive components of cordyceps militaris and other nutrient components, and is prepared through the following steps of completely picking culture mediums (Chinese caterpillar fungus mediums for short) of fruiting bodies after the culture period of the cordyceps militaris is completed, performing low-temperature vacuum drying and air-current ultra-micro crushing, uniformly mixing the crushed powder with a conventional feed, and putting the mixture into a feed granulator for extruding and pelleting. According to the invention, the Chinese caterpillar fungus culture mediums are turned into wealth from waste and are processed into the immunocompetence feed which is used for regulating the immune function of the organism of the river crabs and enhancing the disease prevention and disease resistance of animals; the problems that the ecological environment deteriorates, meat quality becomes bad and the like because medicines, such as antibiotics, are abused can be solved; besides, the utilization rate of the feed is increased, the growth of the river crabs is promoted, the meat quality and the mouth feel are improved, and favorable economic benefits are created; and waste resources are reused, so that the production method has the advantages of low production cost, simple technology, wide application range, high safety, high efficiency and the like.

Description

technical field [0001] The invention relates to a production method of river crab immune active feed, which belongs to the field of feed. Background technique [0002] my country is a big aquaculture country in the world, and its aquaculture production accounts for 70% of the world's total aquaculture production. The production and consumption of aquatic feed also ranks first in the world. Due to late start, insufficient investment, and weak research foundation, the development of my country's aquatic feed industry lags far behind developed countries, and the penetration rate of artificial compound feed is less than 1 / 3, which is extremely disproportionate to my country's status as a large aquaculture country. In 1991, my country's aquatic feed production was only 750,000 tons, accounting for 2.1% of my country's total feed production. In 2004, the output of aquatic feed increased to 8.8 million tons (output value 40 billion yuan), accounting for 12.5% ​​of the total output...

AI Technical Summary

Problems solved by technology

However, after the feed containing antibiotics and growth-promoting agents is fed to river crabs, these two types of substances will remain in the river crabs, causing the crabs to develop drug resistance, thereby threatening the safety of other organisms in the food chain; feed residues that cannot be ingested by river crabs Scattered in the water, resulting in residues of antibiotics, growth promoters and other drugs, seriously polluting the ecological environment
