Embodiment 1

[0060] see figure 1 , prepare the probiotic solid-state fermented feed of the present embodiment according to the following method:

[0061] 1. Prepare 1000kg of germ meal, 1000kg of rapeseed meal, 1000kg of rice bran meal, and 1000kg of sprayed fiber as fermentation substrates, wherein the germ meal is coarsely crushed and passed through a 40-mesh sieve.

[0062] 2. The fermentation substrate is mixed with water according to the material-water ratio of 1:1, the moisture content of the material is adjusted to about 50%, and then steamed and sterilized at 121°C and 0.11MPa for 30 minutes.

[0063] 3. Carry out enrichment culture and liquid fermentation of Candida utilis, Bacillus licheniformis, Geotrichum candidum and Lactobacillus plantarum according to the following methods:

[0064] (1) Candida utilis (Candida utilis)

[0065] A. Prepare primary seed medium: mix 130.1 g of wort medium and 1000 mL of distilled water, and sterilize at 115° C. for 15 minutes.

[0066] B. Pre...

Embodiment 2

[0108] Prepare the probiotic solid-state fermented feed of the present embodiment according to the following method:

[0109] 1. Prepare 1000kg of germ meal, 1000kg of rapeseed meal, 1000kg of rice bran meal, and 1000kg of sprayed fiber as fermentation substrates, wherein the germ meal is coarsely crushed and passed through a 40-mesh sieve.

[0110] 2. The fermentation substrate is mixed with water according to the material-water ratio of 1:1, the moisture content of the material is adjusted to about 50%, and then steamed and sterilized at 121°C and 0.11MPa for 30 minutes.

[0111] 3. Candida utilis (Candida utilis), Bacillus licheniformis (Bacillus licheniformis), Geotrichum candidum (Geotrichum candidum) and Lactobacillus plantarum (Lactobacillus plantarum) were respectively subjected to enrichment culture and liquid fermentation.

[0112] 4. When the temperature of the various fermentation substrates after sterilization drops to 30°C, the inoculation starts. and the mixin...

Abstract

The invention discloses a method for producing a microorganism feed additive by utilizing probiotics and mixed meal. The method comprises the following steps: adding water into fermentation substrates respectively, stirring materials, and then cooking and sterilizing; adding a mixed bacterial liquid into the sterilized fermentation substrates and stirring uniformly after the temperature is lowered to 28-35 DEG C, and carrying out aerobic fermentation under constant temperature; introducing a lactic acid bacterium after the fermentation substrates are fermented and mixed, and then carrying out secondary fermentation; and drying materials after fermentation at a lower temperature, and crushing so as to obtain a microorganism feed additive finished product. The fermentation substrates comprise germ meal, corn spray slurry fibers, rapeseed meal and rice bran meal; the rice mixed bacterial liquid is obtained through mixing bacterial liquids of candida utilis, bacillus licheniformis and cryytococcus neoformans; and the lactic acid bacterium is lactobacillus plantarum, and the inoculum size is 5-10% of the weight of the fermentation substrates.

Description

technical field [0001] The invention relates to a method for producing microbial feed additives by using probiotics and miscellaneous dregs, and belongs to the field of microbial feed additives. Background technique [0002] With the rapid development of animal husbandry, the contradiction between humans and animals competing for food has become increasingly prominent. In order to solve this problem, the scientific and technological circles and industrial circles all over the world are looking for and researching new feed resources. Among them, probiotic solid-state fermented feed has received special attention. . The application of probiotic solid-state fermentation technology to produce protein feed, single-cell protein and bacterial protein can not only provide a large amount of high-quality feed protein sources, but also develop feed additives with special functions. The use of probiotic solid-state fermentation technology to process grain processing by-products such as...
