Problems solved by technology

[0003] However, the traditional fermented feed process requires high fermentation temperature, and the production of fermented raw materials usually requires installation of floor heating or wall heating systems at the bottom and walls of the fermentation tank in winter. These equipment are expensive and consume high energy during use, which increases production costs. It is a bottleneck affecting the production of fermented feed in Northeast China, especially in winter

Embodiment 1

[0030] A method for producing low-temperature fermented feed raw materials suitable for use in winter in Northeast China. This method does not require additional heating equipment and can be used to produce fermented feed raw materials in winter in Northeast China or in other low-temperature regions of my country. The method includes the following steps:

[0031] (1) Grind the soybean meal, corn and rice bran meal to be fermented into 0.5-1.5mm powder, and mix them in a ratio of 50%:20%:30%. Mix the seed solutions of Bacillus pumilus CGMCCNo.4756, Saccharomyces cerevisiae CGMCCNo.8447, and Lactobacillus acidophilus CGMCCNo.5093 according to the ratio of viable bacteria 2:1:1 to make fermented seeds;

[0032] (2) Mix the fermented seeds and water into a fermented liquid, and mix the soybean meal, corn and rice bran meal powder mixture with the fermented liquid at a ratio of 1:0.8;

[0033] (3) Pile the inoculated and mixed raw materials into a raw material fermentation pile. Th...

Embodiment 2

[0039] A method for producing low-temperature fermented feed materials suitable for Northeast China, comprising the following steps:

Abstract

The invention discloses a low-temperature fermentation feed raw material. The low-temperature fermentation feed raw material is prepared from Bacillus pumilus, Saccharomyces cerevisiae and Lactobacillus acidophilus fermentation feed raw materials. In the fresh fermentation feed raw material, the content of probiotics is 10<9> to 10<11> CFU/g; the content of organic acid in the dried fermentation feed raw material is 2 to 3%; and the fermentation feed raw material is fermented at a temperature of 15 to 20 DEG C. The invention also provides a production method for the feed raw material. The fermentation feed raw material produced by using the method is low in antinutritional factor content and rich in small peptides and organic acids and can be easily digested and absorbed by animals; and a formula for a feed with the fermentation feed raw material as a base material does not need animal-derived protein feeds, microecological live bacterium preparations, organic acids and antibiotics, so feed cost is reduced. The feed prepared from the fermentation feed raw material has good feeding effect on animals, and the feeding effect is better than the feeding effect of a feed composed of same components and prepared from non-fermented feed raw materials. A production method for the low-temperature fermentation feed raw material is simple to operate and low in cost, does not have special requirements on fermentation places and equipment and facilitates production of the low-temperature fermentation feed raw material in large scale with whatever is available.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a low-temperature fermented feed material and its application in preparing pig compound feed. Background technique [0002] With the development of compound feed, the traditional feeding mode of corn and soybean meal has matured and made great contributions to the growth and health of livestock and poultry. In recent years, studies have found that after the feed raw materials undergo microbial fermentation, the number of probiotics in the feed is greatly increased, the concentration of organic acids such as lactic acid is greatly increased, the pH value of the feed is significantly reduced, and the digestibility of the feed raw materials is improved. Moreover, the fermentation process greatly reduces the anti-nutritional factors in soybean meal, increases the content of small peptides, and increases the utilization rate of protein in soybean meal and the productio...
