Special feed for crab breeding and preparation method thereof

Abstract

The invention discloses special feed for crab breeding and a preparation method thereof. The special feed for crab breeding is prepared from the following raw materials in parts by weight: 10-20 partsof fish liver oil, 8-10 parts of citric acid, 4-12 parts of bee glue, 4-16 parts of glucose, 2-4 parts of vegetable oil, 4-6 parts of songaria cynomorium herb, 4-10 parts of bamboo worms, 8-10 partsof shrimp meat, 6-8 parts of licorice roots, 50-58 parts of tiny fish, 2-6 parts of perilla leaves, 10-12 parts of barley grass, 8-10 parts of cane shoots, 1-3 parts of compound amino acid, 4-6 partsof scallop muscle, 8-16 parts of honeysuckle flowers and 2-18 parts of beer yeast. The special feed for crab breeding is prepared by the following steps: powder preparing, mixing, granulating, curingand drying. The special feed for crab breeding contains rich nutritional components, provides sufficient nutrients for crabs, has an effect of improving meat quality, increases the development rate ofthe crabs and shortens the growth cycle of the crabs; and meanwhile, the special feed for crab breeding is prepared by a granulating mode, is convenient to feed, can effectively ensure the nutritional value of the fed crabs, effectively prevents fish diseases and has the advantage of high survival rate of crabs.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a special feed for crab breeding and a preparation method thereof. Background technique [0002] Crabs are crustaceans whose bodies are protected by hard shells and breathe through gills. In taxonomy, it is the same animal as shrimp, lobster, and hermit crab. The vast majority of crabs live in the sea or near the sea, and some live in fresh water or land, and crabs are rich in protein and delicious, so they are very popular. [0003] They rely on the female crab 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 rely on the geomagnetic field to determine direction. China has a long history of eating crabs, which are recorded in "Yi Zhou Shu Wang Hui Jie" and "Zhou Li Tian Guan Bu Ren". [0004] As crabs become more and more popular with people, more and more people choose to breed crabs. In the...

Problems solved by technology

[0004] As crabs become more and more popular with people, more and more people choose to breed crabs. In the process of raising crabs, people need to promote the growth of crabs by feeding feed, which also plays a role in improving the meat quality of crabs. However, existing The feed ingredients are single, which cannot achieve this effect, and because the nutrients in the crab feed are unreasonable, there are defects that the growth of crabs is slow and the survival rate of breeding is not high
