Abstract

The invention relates to a method for producing a feed microecological preparation by the synergic fermentation of probiotics, and the method can effectively solve the problems of low conversion ratio and production performance, weak disease resistance and strong toxic and side effects of feeds in the prior art. According to the technical scheme, bacillus subtilis, lactobacillus plantarum and candida are taken as bacterial strains and are inoculated and mixed evenly in a fermentation tank according to the inoculation quantity which is equal to 5%-10% of the volume of a culture medium, wherein the culture medium is prepared by mixing evenly 94%-96% of chrysanthemum meal, 0.8%-1.2% of Astragalus mongholicus, 0.8%-1.2% of forsythia, 0.8%-1.2% of Houttuynia cordata, 0.8%-1.2% of hawthorn and 0.8%-1.2% of pericarpium citri reticulatae by weight percentage and crushing the mixture to 60-100 meshsieves; oxygen ventilation fermentation is performed firstly, wherein the fermentation temperature is 30-35 DEG C, the ventilatory capacity is 0.5-1.2 L/min, the ventilation is stopped for 10 minutes every 30 minutes, the stirring speed is 45-60 r/min, and the culture lasts for 28-40 hours; then, anaerobic fermentation is performed, wherein the fermentation temperature is 32-35 DEG C, the stirring speed is 20-40 r/min, and the culture lasts for 24-48 hours; and finally, the feed microecological preparation is obtained. The feed microecological preparation can increase the utilization rate of protein and promote the growth of animals and is innovation of feed additives.

Description

technical field [0001] The invention relates to the field of biological fermentation, in particular to a method for probiotics cooperative fermentation to produce feed microecological preparations. Background technique [0002] With the continuous development of economy and society, people's quality of life is gradually improving, not only requires food rich in nutrition, flavor, safety and hygiene, but also requires a good living environment, but the breeding industry that is closely related to this has encountered many new problems: such as The prevention and control of livestock and poultry diseases has become more difficult. Avian influenza and swine unidentified high fevers have occurred from time to time. The problem of sewage treatment in the breeding industry is becoming more and more serious, and the safety and flavor problems of animal-derived food. In particular, frequent food safety accidents in recent years have continuously stimulated the nerves of Chinese peo...
