The invention belongs to the field of feed and is particularly suitable for feeding crabs. The crab feed is mainly characterized in that: (1) various animal and
vegetable proteins,
starch, trace elements, an auxiliary agent, a feeding promotion agent and the like serving as raw materials are compounded, so that the
nutrient contents of the crab feed are more balance and comprehensive, and the requirements of the crabs during different growing periods can be met only by adjusting the ration of relative raw materials in the formula; and (2) the modified plastic
processing machinery and process are used, and simultaneously the processes of mixing, shearing, curing, swelling, granulating and the like of the raw materials are also completed. Under the
joint action of the two factors, the shapeof the product is stable, the flexibility is adjustable, and the product is not loosened after being soaked in water for several hours, so that the product is in accordance with the feeding
habit of the crabs. Because the raw materials comprise fly maggots and earthworms that provide a certain amount of natural antibiotic and immunological factor, the product is insusceptible to decay and deterioration and can improve the
disease-resisting capability of the crabs taking the crab feed. The crabs cultivated by the crab feed have the advantages of quick growth, fresh and smooth meat and rich
nutrition.
