Problems solved by technology

[0002] At present, the animal feed of many crabs on the market mostly uses fresh or frozen small miscellaneous fish and fishmeal as the main raw materials. These feeds tend to become mushy in water, which does not conform to the eating habits of crabs who like molded food, and also damages the water quality of breeding. , pollute the environment; in addition, the existing crab feed species are single, the disadvantages such as unbalanced nutritional structure, the crabs that adopt these feeds to raise are small in size, poor in physique, and have low economic benefits, so it is urgent to find a balanced nutritional structure, A new type of green and healthy feed suitable for all growth stages of crabs with good palatability, not easy to hydrolyze and not pollute water sources

Embodiment 1

[0028] A production method of ecological fermented feed for crab cultivation, comprising the steps of:

[0029] Step A, fish meal, fish soluble pulp, chicken powder, peeled bean curd, cottonseed protein, flour, phospholipid oil, fish oil, calcium dihydrogen, rice bran, sodium humate, choline chloride, salt, immune polysaccharide and vitamins 1. After the mineral matter is evenly mixed, the extruded pellet feed is made, and the proportioning of each raw material in the described step A is:

[0030]

[0031]

[0032] Step B: Weigh 5Kg of strains, add 300Kg of tap water to remove chlorine gas, stir evenly and heat to 33°C, activate the strains for 8 hours;

[0033] Step C: Add 1000Kg of extruded granular feed into the mixing tank, evacuate the mixing tank into a vacuum through a vacuum pump, and then use the negative pressure to pump the activated bacterial liquid into the mixing tank in 6 batches through the pipeline. Fill the mixing tank completely, start the motor while...

Abstract

The invention discloses a production method of ecological fermented feed for crab breeding, and belongs to the technical field of feed. The produced feed is comprehensive in nutrition, high-quality raw materials are selected, and all nutrient substances needed by crab growth can be met; according to the feed disclosed by the invention, the design of adding immune polysaccharide, liver and intestine protecting factors and compound probiotics is adopted, so that the physique is enhanced, the immunity is improved, and the body function is activated; the feed is green and environment-friendly, after crabs eat the feed, excreted excrement contains various beneficial bacteria, regular feeding of the fermented feed is equivalent to continuous supplement of probiotics and polysaccharides into water, carbon-nitrogen balance of the water is adjusted, and the bacterial phase of the water is stabilized; and the decomposition effect of beneficial bacteria of the feed continuously provides nutrition for the algae and promotes the growth and stability of the algae, so that the bacteria-algae balance of the water body is maintained, and the stability of the water quality is maintained.

Description
