Embodiment 1

[0013] Methionine 11kg; Taurine 16kg; L-Carnitine 3kg; Lutein (II) 11kg; ; Amino Acid Chelate Salt 5kg; Multidimensional 12kg for Crabs; Organic Minerals 52kg for Crabs; Puffed Corn Flour 230kg. First put 100kg of extruded corn flour into the mixer, then add the above-mentioned feed additive ingredients except the extruded corn flour one by one according to the dosage from large to small, and finally put in the rest of the extruded corn flour, start the mixer, mix for 15min, and the mixing uniformity CV ≤5%, the river crab red ointment fattening feed additive is prepared, and the component measurement accuracy error is less than ±0.5% during preparation. In this example, the organic minerals for crabs are selected from the mixture of ferric citrate and amino chelated copper in any ratio.

Embodiment 2

Abstract

An feedstuff additive for fattening the cream of river crabs comprises methionine, taurine, L-carnitine, lutein(II), decladding element, VC polyphosphate, seaweed meal, betaine, 50 percent choline chloride, amino acid chelating salt, multi-nutrient for crabs, organic minerals for crabs and puffed corn flour. The weight portion of the components is as follows: 10 to 11 portions of methionine, 15 to 16 portions of taurine, 2 to 3 portions of L-carnitine, 10 to 11 portions of lutein(II), 20 to 21 portions of decladding element, 4 to 5 portions of VC polyphosphate, 25 to 26 portions of seaweed meal, 20 to 21 portions of betaine, 20 to 21 portions of 50 percent choline chloride, 4 to 5 portions of amino acid chelating salt, 8 to 12 portions of multi-nutrient for crabs, 48 to 52 portions of organic minerals for crabs and 180 to 230 portions of puffed corn flour. The feedstuff additive can make the river crabs complete the last decrustation smoothly and enter a fattening stage rapidly. Therefore, the fattening rate of the green crabs at the same level is increased by more than 40 percent; the crabs show fat bodies and full and strong legs; and the proportion of the crabs with red cream can be more than 90 percent.

Description

technical field [0001] The invention belongs to the technical field of feed additives for aquaculture, and relates to a feed additive for crabs, in particular to a feed additive for fattening river crab with red cream. Background technique [0002] The commercial quality and value of river crabs are closely related to the nutritional status in the final growth stage. Before and after the last reproduction and shelling of river crabs, the stage of "yellow crab" enters the stage of "blue crab". "The fattening rate is not high, the body is thin, and the legs and feet are not full; the amount of "red paste" is small, and the flavor is not good; the appearance of commercial crabs is not strong, and the color is not bright. From the perspective of the quantity-effect relationship of input and output, it has caused the loss or waste of commodity value and various resources (such as bait, water resources, land, electricity, medicine, tools, etc.) and artificial labor. [0003] The...
