The invention discloses a method for preparing a compound
enzyme and
probiotic preparation for feed through the
biotransformation of corn stalks and soybean meals. The method comprises the following steps of: thoroughly mixing cooked Pu'er tea, first corn stalks, first soybean meals, first wheat
bran, first apple
pomace and first water which are subjected to
pile fermentation, and carrying out acclimation culture so as to form a
leavening agent; and thoroughly mixing the
leavening agent, second corn stalks, second soybean meals, second wheat
bran, second apple
pomace and second water, and carrying out
fermentation, thereby obtaining the compound
enzyme and
probiotic preparation for feed. According to the method, the compound
enzyme and
probiotic preparation with better various performance indexes is prepared through fermenting the corn stalks and the soybean meals by using food-grade safe
flora with stable microbial states, so that the low-cost and high-efficiency
biotransformation of the corn stalks and the soybean meals is realized. Meanwhile, the method disclosed by the invention has the advantages that microbes grow easily, the enzyme activity is high, the
fermentation process is extensive, strict aseptic conditions are not required, and the industrial large-scale production is facilitated.
