Embodiment

[0016] A reasonable mud crab compound feed is characterized in that the feed is prepared from the following raw materials in percentage by weight: fish meal 19-41%, rapeseed meal 6%, brewer's yeast 2%, peeled soybean meal 23%, choline 0.2%, starch 0.2%, flour 18.2-36%, bentonite 0-6.1%, calcium dihydrogen phosphate 1.5%, lysine 0.3-1.2%, methionine 0.1-0.4%, multivitamin 1.5% and fish oil 1-7.0 %.

[0017] As a further optimization of this scheme, the preparation method is as follows: crush the raw materials in the above weight percentages and pass through a 40-mesh sieve, mix evenly, then add water to the mixer and mix for 10 minutes, and finally use the SLX-80 single-screw feed extruder to make 3mm Slow-sinking particles of ×5mm.

Abstract

A reasonable green crab matched feed is characterized by being prepared from, by weight, 19-41% of fish meal, 6% of rapeseed meal, 2% of beer yeast, 23% of dehulled soybean meal, 0.2% of choline, 0.2%of starch, 18.2-36% of flour, 0-6.1% of bentonite, 1.5% of monocalcium phosphate, 0.3-1.2% of lysine, 0.1-0.4% of methionine, 1.5% of multivitamins and multi-minerals and 1-7.0% of fish oil. The reasonable green crab matched feed overcomes the defect that an existing feed is low in utilization rate, low in green crab breeding survival rate and the like.

Description

technical field [0001] The invention relates to the technical field of feed formula, in particular to a reasonable mud crab compound feed. Background technique [0002] Protein is an essential nutrient for the growth of farmed animals. Lack of protein in the feed will lead to slow growth of farmed animals, decreased feed utilization efficiency, and low immunity, while excessive protein content in the feed will increase feed costs, increase nitrogen waste emissions from farmed animals, and pollute the water environment. Therefore, when the protein content in the feed is at an appropriate level, the healthy growth of farmed animals can be effectively promoted. Studies have found that the dietary protein requirements of farmed animals are influenced by the carbohydrates and fats in the feed. The protein-sparing effect is a mechanism whereby farmed animals reduce their dietary protein requirements by increasing the carbohydrate or fat levels in the feed. The protein-sparing e...
