Embodiment 1
[0023] A microecological preparation for poultry, containing bacillus natto, saccharomyces cerevisiae and enterococcus. The number of viable bacteria contained in the bacillus natto is 1.3×10 10 CFU / g, the number of live bacteria in Saccharomyces cerevisiae is 9.8×10 9 CFU / g, enterococci contain 2.7×10 viable bacteria 9 CFU / g.
[0024] The preparation method of probiotics for poultry comprises the following steps:
[0025] 1) the bacterial powders of Bacillus natto, Saccharomyces cerevisiae, and Enterococcus are respectively prepared into aqueous solutions with a mass percentage of 5%;
[0026] 2) Take 0.2 mL of Bacillus natto solution and inoculate it on the medium I, place it at a temperature of 37° C. and cultivate it for 23 hours to obtain the Bacillus natto culture solution; the composition of the medium I is: 0.5 g of beef extract, peptone 0.5g, 0.05g sodium acetate, 0.3g potassium nitrate, 0.2g soluble starch, add water to 100mL, pH 7.0.
[0027] Take 0.2 mL of Sac...
