Abstract

The invention provides a feed for culturing crabs and a preparation method thereof. The feed for culturing the crabs comprises the following raw materials in parts by weight: 1 to 2 parts of choline chloride, 3 to 5 parts of salt, 30 to 40 parts of fish meal, 30 to 40 parts of high gluten flour, 1 to 3 parts of xanthan gum, 0.3 to 0.6 part of a compound mineral additive, 0.03 to 0.1 part of phytase, 2 to 4 parts of a Chinese herbal medicine feed additive, 3 to 7 parts of an immune additive, 23 to 28 parts of rapeseed meal, 17 to 20 parts of oats, 27 to 34 parts of sheep blood, 19 to 24 parts of seaweeds, 14 to 17 parts of hawthorn fruits, 4 to 7 parts of a phagostimulant, and a proper amount of water. The feed has rich nutrients, and can accelerate the cell division of the crabs, and can improve the immunity of fishes, shrimps and the crabs, and enhances the culturing survival rate, and reduces aquaculture water pollution caused by excess feed.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a feed for raising crabs and a preparation method thereof. Background technique [0002] Crabs have a wide variety of food, small fish and shrimp are their favorite, but some crabs eat seaweed, even animal carcasses or plants, they spend most of their time looking for food, they are not picky eaters, as long as they can chew All kinds of food can be eaten, which also affects the tenderness and taste of crab meat.

These feeds tend to become mushy in water, which is not suitable for crabs. Love the eating habits of molded food; in addition, due to the continuous occurrence of diseases such as crab bacteria and viruses, it seriously affects the...

Problems solved by technology

In addition, many crab animal feeds currently on the market use fresh or frozen small miscellaneous fish and fish meal as the main raw materials, which have the disadvantages of destroying fish resources and easily polluting water sources. These feeds tend to become mushy in water, which is not suitable for crabs. Eating habits like molded food; in addition, due to the continuous occurrence of bacterial and viral diseases of crabs, the breeding and production of crabs are seriously affected

[0003] In addition, due to the continuous occurrence of bacterial and viral diseases of crabs, it seriously affects the breeding and production of crabs.

With the rapid development of the crab breeding industry, traditional baits such as miscellaneous fish can no longer meet their huge breeding needs due to the decline in resources, unbalanced nutritional components, and unguaranteed hygiene quality. The development, promotion and application of new feeds have been Become an important factor in promoting the healthy and sustainable development of the crab farming industry

[0004] The existing crab feed has a single variety, unbalanced nutritional structure, can not enhance the immunity and disease resistance of crabs, and is easy to rot and deteriorate.
