Embodiment 1

[0025] Embodiment 1 prepares river crab feed provided by the invention

[0026] The residual medium after removing the fruiting bodies of Cordyceps militaris is a by-product of the process of artificial cultivation of Cordyceps militaris, provided by Nanjing Kangneng Bioengineering Co., Ltd. Pre-crushing the residual culture medium after removing the fruiting bodies of Cordyceps militaris into particles with a size of 2 mm, drying in a low-temperature vacuum, and then ultrafinely pulverizing through high-speed airflow, so that the fineness of the residual culture medium after removing the fruiting bodies of Cordyceps militaris For 120 mesh, save it for later use.

[0027] Weigh 220g of fish meal, 280g of rapeseed meal, 89g of corn, 105g of soybean meal, 100g of subflour, 30g of soybean oil, 35g of dried shrimp, 70g of squid paste, 1g of the residual medium after removing the fruiting body of Cordyceps militaris, 15g of calcium dihydrogen phosphate, and 35g of minerals, 10g of...

Embodiment 2

[0031] Embodiment 2 prepares river crab feed provided by the invention

[0032] The method of preparing the residual medium after removing the fruiting bodies of Cordyceps militaris: weigh 2g of glucose, 2g of peptone, 0.2g of magnesium sulfate, 0.1g of potassium dihydrogen phosphate, 0.2g of triammonium citrate, and 10.02g of vitamin B in 40mL of purified water Fully dissolve and put into the cultivation bottle; weigh 90g wheat and 4g silkworm powder into the above cultivation bottle, and stir evenly; use high temperature and high pressure resistant polypropylene film and rubber band to seal the cultivation bottle mouth; put the above cultivation flat put into an autoclave, and sterilize for 3-4 hours at 121°C and 1.05MPa to obtain the culture medium of the fruiting bodies of Cordyceps militaris; Seal the cultivation bottle of Cordyceps militaris, move it into the sterilized cultivation room, keep the temperature at 20°C, avoid light, and the humidity is 60-65%, and cultivate...

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...
