as can be seen from the table, the crude fiber content of the corn stalk fiber feeds prepared in examples 1-3 of the present invention is significantly reduced compared to the crude fiber content of the corn stalk fiber feeds and raw materials prepared in other groups. And comparative example 1 (distinguished by the ratio of the lactic acid bacteria to the lactobacillus acidophilus to the actinomycetes by volume of 1: 3: 4 with respect to example 3), comparative example 2 (distinguished by the ratio of the lactic acid bacteria to the lactobacillus acidophilus to the actinomycetes by volume of 1: 2: 1 with respect to example 3), comparative example 3 (distinguished by the ratio of the lactic acid bacteria to the lactobacillus acidophilus to the actinomycetes by volume of 1: 1: 1 with respect to example 3), comparative example 4 (distinguished by the ratio of the lactic acid bacteria to the lactobacillus acidophilus by volume of 1: 2 with respect to example 3), comparative example 5 (distinguished by the absence of the addition of ammonium tetramate with respect to example 3), comparative example 6 (distinguished by the absence of the addition of the additive mixture and the ammonium tetramate with respect to example 3) produced corn stalk fiber feed having a significantly lower crude fiber content than examples 1 to 3, it is shown that the reduction of the crude fiber content of the corn stalk fiber feed prepared in the embodiments 1-3 of the present invention is a result of the combined action of each microbial inoculum and ammonium tetramate, and in addition, the dosage ratio of each microbial inoculum also has an important influence on the crude fiber content of the feed.
It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be obvious to those skilled in the art that other variations or modifications may be made on the basis of the above description, and all embodiments may not be exhaustive, and all obvious variations or modifications may be included within the scope of the present invention.
