Problems solved by technology

For one-step anaerobic fermentation, this method has problems such as that aerobic microorganisms such as bacillus and yeast cannot multiply due to insufficient oxygen supply, so that the physiological effects of bacillus and yeast cannot be effectively exerted; for two-step fermentation However, this method has problems such as long process flow, high intensity of large-scale production operations, and difficult control of product quality.

The air filter 5 is connected to the air inlet of the air heater 6 through a pipeline; the air outlet of the air heater 6 is connected to one end of the first electrom...

Embodiment 2

[0068] Weigh 19 kg of fresh soybean meal and 1 kg of soybean skin, mix them evenly, and crush them through a 10-mesh sieve as a fermentation base material. The mixed strains of yeast NKY1, Bacillus subtilis, Lactobacillus plantarum and Lactobacillus reuteri LR1 are used for fermentation. The moisture content of the base material fermentation is controlled at 40%, and 13.33 liters of mixed bacteria seed liquid for biological feed fermentation containing mixed bacteria needs to be prepared. First weigh 266.6g glucose, 40g K 2 HPO 4 and 26.7g KH 2 PO 4 Add a certain volume to clean water preheated to 30°C, stir well to dissolve. Activate the yeast and Bacillus subtilis with activation solution respectively. Then add a certain amount of saccharomyces activation solution and bacillus subtilis activation solution to the nutrient solution, so that the number of viable saccharomycetes and bacillus subtilis in the final fermentation solution reaches 2×10 respectively. 7 cfu / mL. ...

Abstract

The invention discloses a method for producing biological feed through aerobic anaerobic coupling fermentation. According to the method, mixed bacteria of bacilli, lactobacilli and saccharomycetes serve as a fermentation strain of the biological feed; the biological feed is produced by using the aerobic anaerobic coupling solid state fermentation technology, and sterile constant-temperature air isintroduced into a deep material intermittently in the fermentation process, so that growth and propagation of aerobic microorganisms in a lower layer material are facilitated, and the product qualitystability is also improved; the stacking height of material layers can be increased under the ventilation and heat dissipation conditions, and the production capacity of equipment is improved. In addition, the fermented biological feed contains a lot of probiotic bacteria capable of improving intestinal health of animals, the micro-ecological environment of the gastrointestinal tracts can be improved after the animals are fed, and the immunity of organisms can be improved. Besides, the biological feed is rich in lactic acid and has strong mellow fragrance so that the palatability of the feedcan be remarkably improved, the animal feed intake can be improved, the rapid growth of the animals can be promoted, and the production capacity of the breeding industry can be improved.

Description

technical field [0001] The invention relates to the field of feed production, in particular to a method for producing biological feed through aerobic-anaerobic coupled fermentation. Background technique [0002] In the breeding industry, the problems of drug residues, drug resistance and food safety caused by the extensive use of feed antibiotics are becoming more and more severe. Developed countries such as Europe and the United States have begun to completely ban feed antibiotics. The Chinese government has also begun to restrict or ban some feed antibiotics. With the suspension of the four quinolone veterinary drugs of lomefloxacin, pefloxacin, ofloxacin and norfloxacin in food animals at the end of 2015 and the suspension of the feed additive use of colistin sulfate in November 2016, etc. The government's actions to limit, reduce or stop the use of antibiotics in animals have been significantly accelerated, and the complete ban on antibiotics in feed will be the general ...
