Abstract

The invention discloses a crab feed and a preparation method thereof, and belongs to the field of feeds. According to the crab feed disclosed by the invention, nutrient substances of protein nutrientsand oil and fat nutrients are added, so that in the growth process of crabs, nutrition requirements are met; active agents are added, so that the digestive and absorption of the nutrient substances by the crabs is promoted, pathogenic microorganisms are restrained, and the attack rate of the crabs is reduced; transferring and accumulation of fat can be promoted by phosphatide substances in the proteins, so the absorption and utilization of unsaturated fatty acid are promoted, and the crabs have high nutrient values and good immunocompetence; the feed is easy to disperse in water, nutrient substances in the feed are easy to oxidize, and the obtained crab feed is packaged, so that the efficiency that the feed is eaten by the crabs in water can be improved, and the oxidizing damage of the nutrient substances is also avoided; through adoption of the preparation method disclosed by the invention, the problems caused by a conventional feed that the crabs are high in number of diseases, lowin survival rate, and low in reproduction speed; and the yield of the crabs is not increased, so that the breeding benefit is seriously influenced are solved.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a crab feed and a preparation method thereof. Background technique [0002] Crabs are crustaceans whose bodies are protected by hard shells and breathe through gills. In biological taxonomy, it belongs to the same category of animals as shrimp, lobster and hermit crab. Most species of crabs live in the sea or near the sea, and some live in fresh water or land. They rely on female crabs to give birth to small crabs, and each time the female crab will lay a lot of eggs, the number can reach more than millions. 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. [0003] Crab is a kind of food delicious and e...
