Embodiment 1

[0052] Fermentation treatment of 30 tons of sweet potato dregs. The basic components of fresh sweet potato dregs are: crude protein 0.68%, crude fat 0.15%, ash content 0.67, crude fiber 29.3%, starch 44.7%, water content 70%. The implementation process is as follows.

[0053] (1) Candida utilis, Bacillus subtilis and Lactobacillus plantarum were activated on a slant, the culture temperature was 28°C, 31°C and 35°C respectively, and the time was 48 hours. At this time, the microbe count reached 10 9 cfu / g to obtain pure strains. Inoculate the obtained pure Candida utilis and Bacillus subtilis strains into a 1000mL Erlenmeyer shaker flask, control the culture temperature at 28-31°C, and the rotation speed is 150r / min, and cultivate for 24 hours to obtain the bacterial agent; saccharify 1kg corn paste After sterilization, the activated Lactobacillus plantarum was inserted, and cultured anaerobically at 37° C. for 48 hours to obtain the Lactobacillus plantarum inoculum. Inocula...

Embodiment 2

[0058] Fermentation treatment of 30 tons of potato residues. The basic components of fresh potato residue are: 0.72% crude protein, 0.50% crude fat, 0.52% ash, 11.3% crude fiber, 43.8% starch and 70% water content. The implementation process is as follows.

[0059](1) Candida utilis, Bacillus subtilis and Lactobacillus plantarum were activated on a slope, cultured at 28° C., 31° C. and 35° C. for 48 hours to obtain pure strains. Inoculate the obtained pure Candida utilis and Bacillus subtilis strains into a 1000mL Erlenmeyer shaker flask, control the culture temperature at 28-31°C, and the rotation speed is 150r / min, and cultivate for 24 hours to obtain the bacterial agent; saccharify 1kg corn paste After sterilization, the activated Lactobacillus plantarum was inserted, and cultured anaerobically at 37° C. for 48 hours to obtain the Lactobacillus plantarum inoculum. Inoculate the obtained various bacterial agents into the seed tank according to the inoculum amount of 10%, a...

Embodiment 3

[0064] Example 3 was carried out in substantially the same manner as in Example 2, except that when inoculating in the bran medium in step (2), the water content was adjusted to 40%. The content of various components of the potato dregs before fermentation is no longer measured, but the content of various components after fermentation is measured. The results are shown in Table 1 and Table 2 below. In addition, the control group of Example 2 was used as a control for the feed-to-meat ratio, and no other control group was set up. The results are shown in Table 3 and Table 4 below.

Abstract

The invention provides multi-strain leaven used for potato dreg fermentation. The multi-strain leaven comprises or is composed of candida utilis leaven, bacillus subtilis leaven and lactobacillus planticola leaven. The invention also provides a method of preparing feed from potato dregs through fermentation by utilizing the multi-strain leaven, the feed prepared by the method and applications of the feed. Compared with products at present, a single nutrient is quickly converted into other nutrients, other nutrients are enriched and optimized, the crude protein content of the feed is significantly increased, palatability of the feed is improved, the feed conversion ratio is obviously reduced and the braising cost is significantly reduced.

Description

technical field [0001] The invention relates to a method for preparing solid-state fermented animal protein feed by using microorganisms to ferment organic wastes in the food industry, in particular using microorganisms to ferment potato dregs left after processing potato crops. technical background [0002] Potato crops are a very important class of crops, mainly referring to a class of terrestrial crops with edible roots or underground stems, generally including potatoes, sweet potatoes, cassava, yams, konjac and jicama. China is a major producer of potato crops in the world, and the staple food of potato crops has become a new measure to ensure my country's food security. Among them, the three major potato crops, potato, sweet potato and cassava, play an important role in the development of the agricultural industry. Most of the potato crops are industrially used to produce starch, and a large amount of potato residues are produced every year, but their reuse is not suffi...
