Abstract
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.
Description
Technical field: [0001] The invention patent belongs to the category of feed. Background technique: [0002] Crab is a delicious and easily absorbed food, which is deeply loved by people. The crab's food is very miscellaneous, all kinds of animals and plants, as long as it can chew, it will eat, which will affect the tenderness and taste of its meat. Generally speaking, appropriately increasing the proportion of animal feed in the mature stage of crabs has a great effect on improving the quality of crabs. At present, the animal feed of many crabs is mainly made of fresh or frozen small miscellaneous fish and fish meal, which has the disadvantages of destroying fish resources, easily polluting water sources, and unbalanced nutrients. It is in line with the eating habits of crabs who like shaped soft food. In addition, these feeds are easy to spoil, pollute the water source and affect the normal growth of crabs. This patent is specially developed to overcome the shortcomings...
