Abstract

The invention discloses an aged grain rice compound fermented feed and a production and preparation method thereof. The production and preparation method comprises the following steps: shelling and smashing aged grain, and then screening to obtain aged grain rice flour; smashing wheat bran and screening to obtain wheat bran flour; mixing the aged grain rice flour with the wheat bran flour to obtain a mixed fermentation raw material; mixing lactobacillus, bacillus licheniformis, bacillus subtilis, saccharomyces cerevisiae and clostridium butyricum to obtain a mixed strain; mixing the mixed fermentation raw material with the mixed strain and adding water to obtain fermented mixed wed feed; respectively adding citric acid and cellulose to the fermented mixed wed feed, uniformly mixing and then fermenting for 3-5 days; and drying and smashing the leavening to obtain the aged grain rice compound fermented feed. The aged grain rice compound fermented feed and the production and preparation method have the advantages of being simple in process and easy to implement, and the prepared aged grain rice compound fermented feed is rich in nutrition and relives the harm of exceeding aspergillus flavus on the health of poultry.

[0022] First, it should be noted that the present invention not only provides a compound fermented feed for aged grains and rice, but also provides a production and preparation method of the compound fermented feed for aged grains and rice. Among them, the production and preparation method of aged grain and rice compound fermented feed specifically includes the following steps:

[0023] 1. Dehulling the aging grain rice to obtain aging grain rice, and preliminarily crushing the aging grain rice;

[0024] 2. Carry out the secondary pulverization and sieving of the aged grain rice after preliminary crushing to obtain the aged grain rice flour that meets the requirements, which is used as the main raw material of fermentation;

[0025] 3. The wheat bran is crushed and sieved to obtain the wheat bran powder meeting the requirements, which is used as the fermentation raw material auxiliary material;

[0026] 4. Weigh the aged grain rice flour obtained in step 2 and the wheat bran flour obtained in step 3 and mix them to obtain mixed fermentation raw materials; wherein the mass ratio of aged grain rice flour to wheat bran flour is 8:1.90 ;

[0027] 5. Weigh Lactobacillus, Bacillus licheniformis, Bacillus subtilis, Saccharomyces cerevisiae and Clostridium butyricum and mix them to obtain a mixed strain;

[0028] 6. Weigh the mixed fermentation raw materials obtained in step 4 and the mixed strains obtained in step 5 and mix them, and add water to the mixture of the mixed fermentation raw materials and the mixed strains, stir and mix to obtain the fermentation mixed wet material; wherein, mix The mass ratio of strains to mixed fermentation raw materials is 0.4~0.7:99.0, and the moisture content in the fermentation mixed wet material is 55%~60%;

[0029] 7. Add citric acid and cellulase to the fermented mixed wet material obtained in step 6, and transfer to the reaction vessel to ferment for 3 to 5 days after mixing to obtain the fermented product. The mass ratio of citric acid to the mixed fermentation raw material 0.2~0.4:99.0, and the mass ratio of cellulase to mixed fermentation raw materials is 0.1~0.2:99.0;

[0030] 8. Drying and crushing the fermented product obtained in step 7 to obtain the final aged grain and rice compound fermented feed.

[0031] In the above steps two and three, the sieving tool used in the sieving process is 40-60 mesh.

[0032] In the above step 5, the mass ratio of Lactobacillus, Bacillus licheniformis, Bacillus subtilis, Saccharomyces cerevisiae and Clostridium butyricum is 0.8-1.2: 0.8-1.6: 1.0-2.0: 0.6-1.2: 0.4-1.0. The effective number of live bacteria of Lactobacillus is 1×10 8 CFU/g, the effective viable number of Bacillus licheniformis is 5×10 8 CFU/g, the effective viable number of Bacillus subtilis is 8×10 8 CFU/g, the effective viable number of Saccharomyces cerevisiae is 5×10 7 CFU/g, the effective viable count of Clostridium butyricum is 5×10 7 CFU/g.

[0033] In the above step 7, the environmental temperature of the fermentation is 35-41°C.

[0034] In the above step eight, the temperature of the drying treatment is 65°C.

[0035] The aged grain and rice compound fermented feed provided by the present invention has a crude protein content of 25% to 31%, a pH value of 4.5 to 5.0, and small peptides with a mass of less than 10KDa account for 70% to 80% of the total polypeptide content. The number of effective viable bacteria ≥ 4 billion/g.
