Crab feed and processing method thereof

Abstract

The invention belongs to the technical field of aquatic feed, and particularly relates to a crab feed and a processing method thereof. The crab feed is prepared from 21% of fishmeal, 16% of tofukasu,15% of vegetable cake meal, 16% of corn flour, 18% of bran, 10% of a mixture, 3% of paint oil, 1% of an organic salt additive and 0.1% of ecdysone added into the feed. The method comprises the steps of preparing the raw materials, wherein all the raw materials are prepared and weighed according to the weights; stir-frying the raw materials, wherein the corn flour, the tofukasu and the mixture aremixed and then placed into a stir-frying pan, the temperature of the stir-frying pan is controlled to be 45 DEG C through a heating disc, stir-frying is performed for 18 min through a stir-frying device 5, and then, rice wine is added for fermentation for 2 d for use; boiling the raw materials; performing mixing and granulating. Metabolism of fat inside crabs can be promoted, fat is converted intoenergy to be released, growth of crabs is accelerated, the yield of crabs is increased, the culture cost is lowered, and the anti-disease immunity of the crabs can be improved.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, in particular to a crab feed and a processing method thereof. Background technique [0002] Crabs are omnivores and can feed on plants, grains and small animals. The commercial feed purchased in the market today is not highly targeted, and its nutritional value and freshness are far from enough, so it cannot provide better nutritional value to crabs in the growth period, and prolong the growth cycle. [0003] When raising crabs, protein is an essential nutrient for crabs. In the stage of growing crabs, the total crude protein is required to be about 35%. The existing crab feed has a single component and lacks nutrients, which is not conducive to the growth of crabs. [0004] At the same time, when the existing crab feed is processed, due to the different proportioning components of the crab feed, it is necessary to control the temperature of different raw materials when the crab feed is hea...
