Microorganism fodder production method based on pleurotus eryngii mushroom cultivating residues

Abstract

The invention discloses a microorganism fodder production method based on pleurotus eryngii mushroom cultivating residues and belongs to the technical field of fodder production. The microorganism fodder production method comprises the following steps of: firstly, preparing a first-stage fermentation culture medium based on the pleurotus eryngii mushroom cultivating residues; then inoculating saccharomycetes and bacillus in the first-stage fermentation culture medium to carry out first-stage aerobic fermentation; then, adding soya bean meals and rapeseed meals to prepare a second-stage fermentation culture medium; and finally, inoculating lactobacillus and bifidobacterium into the second-stage fermentation culture medium and uniformly mixing; and carrying out anaerobic fermentation to obtain a finished product. When the fodder is used for feeding animals, the fodder conversion rate is low, the investment is less and the output is high; and meanwhile, wastes in the production of pleurotus eryngii are effectively utilized. According to the microorganism fodder obtained by the invention, raw materials do not need to be sterilized and products do not need to be subjected to drying treatment; the obtained biological fodder is enriched with active probiotic bacteria, functional enzymes and auxiliary factors, and the probiotic bacteria and the functional enzymes are remained; and the fodder is low in price and excellent in performance and the adding amount can reach 5-40% in a feeding process; and therefore, economic benefits and social meanings are good.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a microbial feed or a microbial feed additive. Background technique [0002] At present, the market scale of the feed industry is huge, and it is increasing at a rate of about 15% per year, but the profit is very low. Most of them are produced with grain as raw material, and the cost is difficult to reduce. It will be one of the future development directions to produce cheap and high-quality biological feed through a series of microbial treatments from non-grain raw materials. At present, there are only a small number of domestic companies engaged in the research and development and production of fermented feed or biological feed, but they also use grain as the main raw material, so it is difficult to greatly reduce the cost, and it is not easy to achieve great development and high profits. Some companies use anaerobic fermentation as the main process of biological feed, and use no...

Problems solved by technology

But in this patent, without adding cellulase, the efficiency of degrading cellulose is greatly reduced, because Bacillus subtilis, yeast, lactic acid bacteria, etc. cannot effectively degrade lignocellulose

Moreover, the probiotics in this patent have undergone one-step fermentation, and there is a great contradiction between the growth of aerobic bacteria and anaerobic bacteria. In addition, the final product needs to be stored dry, which consumes a lot of energy, the mortality rate of probiotics is high, and the activity of digestive enzymes is relatively low.
