Abstract

The invention discloses feed for increasing the survival rate of crabs and improving the meat quality of the crabs. The feed is prepared from, by weight, 80-120 parts of fish meal, 30-60 parts of bean pulp, 5-15 parts of corn, 2-8 parts of wheat, 3-6 parts of dried-powder of housefly larvae, 2-6 parts of blood worm powder, 3-5 parts of margarya meat powder, 1-4 parts of dried and shelled shrimps, 1-5 parts of beer yeast, 2-6 parts of fish oil, 2-7 parts of seaweed meal, 1-5 parts of potamogeton maackianus, 2-5 parts of shrimp shell powder, 1-3 parts of monopotassium phosphate, 2-4 parts of mountain flour, 1-4 parts of fish decavitamin and 2-6 parts of astaxanthin. The feed contains rich protein, starch, amino acid, cellulose and microelements, the immunity of the crabs can be effectively improved, the survival rate of the crabs can be increased, and the meat quality of the crabs can be improved.

Description

Technical field [0001] The invention relates to the field of feed, in particular to a feed for improving the survival rate and meat quality of crabs. Background technique [0002] At present, the molecular structure of astaxanthin has a relatively active electronic effect. It can provide electrons to free radicals or attract the unpaired electrons of free radicals. By absorbing the excess energy of free radicals into the molecular chain, it will cause molecular degradation and prevent other molecules or The tissue is damaged, while preventing the rapid degradation of lipid-rich membranes. It can be seen that the structural characteristics of astaxanthin make it easy to react with free radicals to scavenge free radicals and play an anti-oxidant effect. [0003] There are many types of crabs. There are about 600 types of Chinese crabs, including portunus, blue crab, frog crab, Guan Gong crab and so on. Crab is delicious and rich in protein and trace elements, which has a good nouri...
