The invention discloses a larval crab compound feed. According to the technical scheme, the larval crab compound feed is prepared from the following components in percentage by weight: 40 to 60 percent of steam
fish meal, 8 to 20 percent of bean pulp, 0 to 10 percent of rice
bran, 0 to 5 percent of South Pole
krill meal, 2 to 5 percent of
zymosan, 1.0 to 2.0 percent of high-quality
fish oil, 10 to 30 percent of wheat, 1 to 2 percent of a
vitamin and mineral salt premix, 0.5 to 1.5 percent of
choline chloride and 0.1 to 0.5 percent of
astaxanthin. A production method comprises the following steps: mixing all the formula components in a mixing
machine to enable the variance to be less than 5 percent; after the components are uniformly mixed, carrying out pulverizing through an ultrafine
pulverizer to enable all the components to pass through a
sieve of 80 meshes; introducing
water vapor, which account for 15 percent of the total
mass of all the components and has the temperature of 100 to 105 DEG C, to modulate the pulverized materials in a modem for 2 to 3 minutes, and then enabling the raw materials to enter an
extrusion granulator for
granulation at the temperature of 90 to 95 DEG C;
drying the extruded feed granules. The scheme provided by the invention is easy to prepare and balanced in
nutrition, and can meet the growing requirements of larval crabs.
