Abstract

The invention relates to a composite formula feed for breeding blue crabs. The raw materials of the feed comprise the following components in percentage by weight: 25-28% of wheat flour, 9-12% of corn DDGS, 15-18% of fly larva powder, 12-14% of albumen powder, 3-5% of beer yeast, 1-2% of DHA micro algae oil, 1% of EPA refined oil, 2% of fish oil, 1% of blue-green algae powder, 0.1-0.2% of choline chloride, 0.2% of sodium chloride, 0.04-0.05% of L-carnitine, 2-4% of isomaltooligosacharide, 0.3% of composite bacillus, 0.05-0.06% of mildewproof agents, 1-3% of compounding adhesives, 1-2% of composite minerals, 0.5-1.5% of composite vitamins, and the balance of biogas residues. Various components are effectively mixed, and fish meal and soybean meal are prevented from being used, so that the influence of nutrition resistant factors in the soybean meal on the growth of the blue crabs is reduced.

Description

technical field [0001] The invention belongs to the technical field of mariculture, and in particular relates to a compound formula feed for the cultivation of Portunus trituberculatus. Background technique [0002] As the main protein source of aquafeed, fishmeal has been widely used in aquaculture because of its high protein content, balanced amino acid composition, good palatability, and low anti-nutritional factors. The scale of aquaculture in the world is growing at an annual rate of 11%, but the annual output of fish meal in the world is declining. In recent years, the annual output of fish meal is only maintained at 6-7 million tons, resulting in an imbalance between the supply and demand of high-quality feed protein sources. Therefore, finding high-quality fishmeal substitute raw materials and studying the addition ratio of alternative protein sources have become key issues for the sustainable development of aquaculture. Soybean meal has been widely studied as a hig...
