Microbial fermentation feed as well as production method and application thereof

Abstract

The invention discloses microbial fermentation feed as well as a production method and an application thereof. The production method of the microbial fermentation feed comprises the following steps: (1) lactic acid bacteria, Clostridium butyricum Cb-2, yeast, Bacillus subtilis, a fermentation base-material and water are uniformly mixed, and a fermentation raw material is obtained; 2) aerobic fermentation and anaerobic fermentation are carried out in order for the fermentation raw material obtained in the step (1), and after fermentation, the feed is obtained. The microbial fermentation feed contains microecological viable organisms, and the total amount of beneficial bacteria is more than 5 x 10<9> cfu/g; the amount of mould and the content of mould toxin are lower than national limit standards; the feed is rich in organic acid, the content of lactic acid reaches 2.5%, and pH value is lower than 4.5; the titer of antibacterial peptide is higher than 1000 u/g, the titer of neutral protease is 150 u/g, the titer of alpha-amylase 300 u/g, dry weight for above, and the titer of total protease is higher than 600 u/g; the whole fermentation process is controlled in the range of 8-24 hours, the fermentation time is saved, and the dissipating energy is controlled below 3%.

Description

technical field [0001] The invention belongs to the field of feed, and relates to a microbial fermented feed and a production method and application thereof. Background technique [0002] With the improvement of people's living standards, people pay more attention to the safety, nutrition and health of animal food, which promotes the healthy and large-scale development of the breeding industry. In recent years, the number and scale of large-scale livestock and poultry farms in my country have continued to increase, and the annual feed demand has reached hundreds of millions of tons; however, the current application of microbial fermented feed is not ideal, and the application effect is not good. After planting (using a single yeast or spore), the process is not good (simple aerobic fermentation), high energy consumption increases costs, etc. There are mainly the following problems in the production and circulation process: 1) The problem of large energy consumption for ferme...

AI Technical Summary

Problems solved by technology

In recent years, the number and scale of large-scale livestock and poultry farms in my country have continued to increase, and the annual feed demand has reached hundreds of millions of tons; however, the current application of microbial fermented feed is not ideal, and the application effect is not good. After planting (using a single yeast or spore), poor technology (simple aerobic fermentation), high energy consumption and increased costs, etc.

There are mainly the following problems in the production and circulation process: 1) The problem of large energy consumption for fermentation: the common fermentation process adopts aerobic bacteria fermentation, and the energy consumption of the whole fermentation process is as high as 20%, which reduces the conversion rate of fermented feed; Additional carbon sources such as sugar are added, which increases production costs

2) Problems of "keeping alive" beneficial bacteria and "keeping fresh" of biologically active ingredients: After the production, storage, transportation and circulation of fermented feed, the vitality of beneficial bacteria and the "keeping alive and fresh" of biologically active ingredients in the product are difficult to meet the expected values. Some even last for a short period of about a week
