Method for improving quality of mushroom bran feed through multi-strain mixed fermentation

Abstract

The invention provides a method for improving the quality of a mushroom bran feed through multi-strain mixed fermentation, which comprises the following steps: by taking mushroom bran after three times of fruiting as a fermentation substrate and taking lactobacillus acidophilus, saccharomyces cerevisiae and bacillus subtilis which are independently screened and optimized in a laboratory as fermentation strains, performing fermentation under the optimal fermentation condition and the natural pH condition, and after the fermentation is finished, performing low-temperature drying to obtain the fermented mushroom bran feed. The nutritional ingredients and feed quality of the mushroom bran fermented by mixing the three strains of the bacillus subtilis, the lactobacillus acidophilus and the saccharomyces cerevisiae are remarkably improved, the problems that the mushroom bran is poor in palatability, low in absorption and utilization rate, prone to mildewing, not prone to stable storage and the like are greatly solved, and the mushroom bran is a novel feed resource. The fermented mushroom bran feed is rich in probiotic metabolites, and can maintain the balance of gastrointestinal flora of animals, inhibit the proliferation of bad microorganisms in intestinal tracts, improve the absorption and utilization rate of the feed, enhance the immunity of animal organisms, and improve the health level and production performance of the animals.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for improving the quality of bacterial chaff feed through multi-strain mixed fermentation. Background technique [0002] China is the world's largest producer of edible fungi. According to incomplete statistics, my country's output of edible fungi has reached 39.6 million tons in 2019, accounting for more than 75% of the world's total output of edible fungi. Mushroom chaff is the residue of the culture medium left after the cultivation of various fungi, which contains protein, amino acid and other nutrients. It is estimated that the annual output in my country is about 40 million tons. With the development of industrialization of edible fungi, the output of edible fungi has grown rapidly, and the number of mushroom chaff has also increased year by year. At present, only a small part of these fungus chaffs are developed and utilized as organic fertilizers or cultivation substrates, a...
