Compound feed for red cream crabs and preparation method thereof

Abstract

The invention provides a compound feed for red cream crabs and a preparation method thereof, and the compound feed for the red cream crabs can be used for solving the problems that the red cream crabs cultured traditionally are slower in growth, not full in cream and the like. The formula of the compound feed comprises the following raw materials in percentage by weight: 18-25% of flour, 1-5% of fish meal, 5-20% of soybean meal, 10-20% of rapeseed meal, 5-15% of cottonseed meal, 1-5% of shrimp shell powder, 1-6% of squid liver paste, 1-6% of corn, 1-6% of corn protein powder, 5-14% of corn plantule cake, 1-3% of stone dust, 1-3% of fish oil, 2-7% of soybean lecithin powder, 0.5-2% of calcium dihydrogen phosphate, 0.1-0.5% of common salt, 0.1-0.4% of choline chloride, 0.01-0.02% of antioxidant, 0.04-0.09% of antifungal agent, 0.01-0.03% of bile acid, 0.1-0.3% of multiple vitamins for the crabs, 0.1-0.30% of multiple minerals for the crabs, 0.03-0.06% of vitamin E, 0.03-0.09% of 35% vitamin C phosphate ester and 0.006-0.009% of astaxanthin. The preparation method comprises the following steps: performing ultra-micro pulverization on all the raw materials, enabling 95% of the raw materials to pass an 80-mesh standard sieve, pelletizing at the temperature of 105 DEG C and simultaneously curing for 45 minutes after heat preservation. The compound feed for the red cream crabs, provided by the invention, can meet the nutritional demands for fattening the cream crabs, simultaneously enable crab roe to be red in color and bring higher farming income to farmers.

Description

technical field [0001] The invention belongs to the field of feed for aquaculture animals, and in particular relates to a red cream crab compound feed and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's living standards, rare aquatic products such as river crabs have gradually entered the homes of ordinary people, which further promotes the rapid development of the river crab breeding industry. Due to the consumer's preference for red crabs and the ability to breed plump red crabs in a short breeding cycle in order to increase the selling price, obtaining higher breeding benefits has become an important issue day by day. [0003] The traditional river crab farming mode is extensive, and the bait fed is generally chilled miscellaneous fish, snails, clam meat, river mussel meat, coarse grains, etc. The disadvantages of this method are low yield, slow growth rate, and labor intensity. Large, high labor co...
