River crab feed and production process thereof

Abstract

The invention discloses river crab feed, which comprises fish meal, vegetable dregs, corn, soya bean meal, inferior meal, soya-bean oil, shrimps, cuttlefish ointment, monocalcium phosphate, mineral substances for crabs, vitamin for the crabs, a binder, 0.7 to 14.0 mg / kg of cordycepin, 131.0 to 2,620.0 mg / kg of cordycepic acid, 0.1 to 2.0 mg / kg of adenosine and 290.0 to 5,800.0 IU / kg of superoxide dismutase. The river crab feed has the high utilization rate, reduces the pollution of feed residues to environment, avoids the negative effects of antibiotic residues and tolerance caused by the antibiotic residues, is safe and harmless to the craps and the environments and can enhance the immunity of the crabs and accelerate the growth of the crabs. The invention also provides a production process of the river crab feed, which has the characteristics of low cost and simple and convenient operation.

Description

technical field

[0001] The invention relates to the field of aquaculture feed processing, in particular to a river crab feed and a production process thereof. Background technique

[0002] The river crab is the Chinese mitten crab, and its Latin name is Eriocheir sinensis. It is a unique aquatic product in my country. However, with the continuous expansion of the breeding scale and the continuous increase of the breeding density, the breeding environment is deteriorating, which seriously threatens the growth and breeding of river crabs. At present, river crab feed mainly prevents river crab diseases by adding antibiotics such as kitasamycin to basic feed, and accelerates river crab growth by adding growth-promoting agents such as olaquindox. 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...
