Problems solved by technology

[0003] Crayfish has become an important economically farmed species in China in recent years. In the process of commercial farming, because the living environment of crayfish is artificially restricted, and the breeding density is much higher than that of wild populations, it is prone to susceptible to germs, decreased vitality, and meat quality. How to improve the quality of crayfish farming and how to increase the profit of farming has become a major problem at present. Many farmers have thought of starting from the breeding feed and improving the formula of the breeding feed to make the crayfish grow stronger. However, the effect is not ideal. , mainly have problems such as poor absorption effect, poor palatability, and easy to produce anorexia

Embodiment 1

[0024] The preparation method of feed additive comprises the following steps:

[0025] 1) Calculated according to parts by weight, weigh each raw material: 15 parts of Astragalus membranaceus, 25 parts of Codonopsis pilosula, 10 parts of Gardenia, 16 parts of Wujiapi, 8 parts of Angelica sinensis, 5 parts of Cocklegrass, 4 parts of Chenpi and 4 parts of Dilong ,spare;

[0026] 2) Mix the raw materials except Earthworm, add water to cook, filter to obtain the filtrate and filter residue; put the filter residue into a beater and add an appropriate amount of water for beating treatment to obtain slurry I, and heat slurry I to 40 ° C, and then Cellulase is added for enzymolysis to obtain enzymatic solution I; the amount of cellulase added is 0.2% of the weight of slurry I.

[0027] 3) Put Dilong into a beater alone and add an appropriate amount of water for beating treatment to obtain slurry II, raise the temperature of slurry II to 40°C, and then add neutral protease for enzymol...

Embodiment 2

[0030] A feed additive comprising the steps of:

[0031] 1) Calculated according to the parts by weight, weigh each raw material: 25 parts of Astragalus membranaceus, 15 parts of Codonopsis pilosula, 20 parts of gardenia, 8 parts of Wujiapi, 16 parts of angelica, 10 parts of Herba Commodum, 8 parts of tangerine peel and 8 parts of earthworm ,spare;

[0032] 2) Mix the raw materials except earthworm, add water to cook, filter to obtain filtrate and filter residue; put the filter residue into a beater and add an appropriate amount of water for beating treatment to obtain slurry I, and heat slurry I to 60 ° C, and then Cellulase is added for enzymolysis to obtain enzymatic solution I; the amount of cellulase added is 0.4% of the weight of slurry I.

[0033] 3) Put Dilong into a beater alone and add an appropriate amount of water for beating treatment to obtain slurry II, raise the temperature of slurry II to 50°C, and then add neutral protease for enzymolysis to obtain enzymatic...

Embodiment 3

[0036] A compound feed for crayfish farming, calculated in parts by weight, comprising the following raw materials:

[0037] 46 parts of corn flour, 6 parts of chicken powder, 24 parts of millet, 16 parts of soybean meal, 14 parts of peanut meal, 20 parts of distiller's grains, 2 parts of soybean lecithin, 6 parts of zeolite powder, 0.6 part of manganese, zinc and iron and the Feed additive 1 part.

Abstract

The present invention provides a compound feed for crayfish cultivation. The feed comprises the following raw materials in parts by weight: 40 to 50 parts of corn flour, 4 to 8 parts of chicken powder, 20 to 30 parts of millet, 10 to 20 parts of soybean meal, 10 to 20 parts of peanut meal, 15 to 25 parts of distiller's grains, 1 to 3 parts of soybean lecithin, 4 to 8 parts of zeolite powder, 0.2 to 0.8 part of trace element and 0.5 to 1.5 parts of a feed additive. The feed additive is obtained by mainly fermenting milk-vetch roots, dangshen, cape jasmine fruits, acanthopanax root bark, Chineseangelica, monochoria vaginalis, dried tangerine peel and earthworms through bacillus subtilis. The feed not only enhances the immunity of crayfishes, improves the survival rate, but also has the advantages of good palatability.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a compound feed for crayfish breeding. Background technique [0002] Freshwater crayfish are typical omnivores. It eats grass, aquatic plants, grain feed and animal feed. Feeding pure natural organic feeds such as artificially propagated aquatic organisms, small animals, and planted aquatic plants is better in palatability, rich in nutrition, fresh and delicious than purchased commercial feeds, and it is completely unnecessary to buy compound feeds. It can not only avoid harmful ingredients such as hormones in the commercial feed exceeding the standard, ensure that the commercial lobster is green and pollution-free, but also save a large amount of feed investment every year. [0003] Crayfish has become an important economically farmed species in China in recent years. In the process of commercial farming, because the living environment of crayfish is artificial...
