Embodiment 1

[0029] (1) Preparation of fungal seed liquid: Take white rotten wood, dig out the fungus block and put it into fresh potato dextrose agar (PDA) medium, shake and culture at 25°C for 72 hours at a speed of 150rpm, and then prepare the fungal seed liquid.

[0030] (2) Preparation of fungal liquid: join the fungal seed liquid in the PDA liquid medium with a volume ratio of 0.3%, keep the temperature at 25° C., and cultivate the conditions of 120 rpm rotating speed for 5 days to obtain the fungal liquid (OD600 is 0.8 -1).

[0031] (3) 100 parts of angelica slag, 50 parts of straw and 20 parts of wheat bran were respectively pulverized into granules with a particle size of 0.4 cm, and mixed uniformly to obtain a granular mixture.

[0032] (4) Disperse the granular mixture in water of equal mass, then add the amount of urea shown in Table 1, soak for 4 hours, and turn over the material every half an hour.

[0033] (5) Heat up the temperature of the material obtained in step (4) to ...

Embodiment 2

[0046] Example 2 In this example, the same method was used to prepare materials, and feeds with different particle sizes were prepared, as shown in the table below.

[0047] Table 3 Effects of different particle sizes on pellet feed quality

[0048]

[0049] It can be seen from Table 3 that with the reduction of the crushed particle size, the pulverization rate of the pellet feed decreases, the hardness increases, and the stability in water increases.

Embodiment 3

[0050] Example 3 In this example, fungi and yeast in distiller's grains are used for synergistic fermentation, and it is expected that the enzyme systems of each strain will complement each other to increase the content of polysaccharides.

[0051] (1) 100 parts by weight of traditional Chinese medicine dregs, 100 parts by weight of straw and 40 parts by weight of wheat bran were respectively pulverized into granules with a particle size of 0.8 cm, and mixed uniformly to obtain a granular mixture.

[0052] (2) Disperse the granular mixture in water of equal mass, then add urea, the quality of urea is 5% of the total amount of the granular mixture; soak for 4 hours, turn over once every half hour.

[0053] (3) The temperature of the material obtained in step (2) is raised to 240° C. for steam explosion treatment, the treatment time is 20 minutes, and the pressure is 3 MPa.

[0054](4) After cooling the material treated in step (3), spray 5 parts by weight of fungal liquid, add ...

Abstract

The invention discloses a method for preparing fodder based on dregs of traditional Chinese medicine decoction. According to the method, firstly, raw materials are subjected to blasting pretreatment through a urea solvent, then, multi-strain mixed fermentation is conducted, and finally, the rough fodder of the dregs of the traditional Chinese medicine decoction is obtained through the smashing granulation technology. The fodder is high in crude protein content and abundant in nutrition and can be absorbed by animals easily. By means of the method, the environment pollution caused by the dregs of the traditional Chinese medicine decoction can be avoided, the problem of fodder shortage in animal breeding industry development is relieved, and the method has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of animal feed production and relates to a method for preparing feed based on traditional Chinese medicine dregs. Background technique [0002] Chinese medicine residue is the residue left after Chinese medicinal materials are extracted by a certain solvent or other methods. At present, these traditional Chinese medicine residues are mostly treated as garbage, which is not only a great waste of resources, but also pollutes the environment. With the development of animal husbandry and aquaculture, traditional feed resources (all kinds of grains, bran, soybean meal, etc.) can no longer meet the rapidly growing feed market. Animal feeds that are fermented with traditional Chinese medicine dregs are used to feed pigs, cattle, and sheep. It not only supplements protein, calcium, magnesium, iron and other trace elements, but also has some medicinal effects in preventing and curing various diseases of livestock an...
