Abstract

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.

Description

technical field [0001] The invention relates to the technical field of river crab feed processing, in particular to a production method of crab compound feed. Background technique [0002] River crab is an important aquatic economic animal in China, and it is bred in large quantities in Jiangsu, Anhui, Hubei and other places. River crabs are generally cultured for two years. In the first year, the megalopa is raised to the crab, and in the second year, the crab is raised to the adult crab. At present, the compound feed for adult crab breeding is relatively mature. Yet, the compound feed specially designed for button crab culture has not seen yet. Therefore, it is of great significance to design a special formula for crab compound feed and design a reasonable production method to improve the healthy breeding level and sustainable development of river crabs. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the main purpose of the present inv...
