Compound biological strain for feed and preparation method of fermented feed

Abstract

The invention provides a compound biological strain for feed. The compound biological strain comprises enterococcus faecalis, lactobacilli, saccharomycetes, bacillus subtilis and bacillus coagulans, wherein the bacterial count ratio of the enterococcus faecalis to the lactobacilli to the saccharomycetes to the bacillus subtilis to the bacillus coagulans is (0.5 to 1.5):(0.5 to 1.5):(0.1 to 0.5):(4 to 6):(0.5 to 1.5). The compound biological strain for feed and a preparation method of fermented feed provided by the invention have the advantages that the release of crude protein and amino acid in coarse feed can be promoted, and the animal absorption is facilitated.

Description

technical field [0001] The invention relates to the field of feed, in particular to a compound biological strain for feed and a method for preparing fermented feed. Background technique [0002] Woody plants and straw contain relatively high levels of crude protein and amino acids, of which lysine and methionine are 1.12%-1.43% and 0.14%-0.25% respectively, and the proportion of amino acids is suitable for animal growth and is conducive to the absorption of livestock and poultry Utilization, this makes woody feed and straw a good protein feed, and people have also used it in livestock and poultry farming in recent years. However, because woody plants and straw are rich in crude fibers and proteins such as cellulose, hemicellulose, pectin substances, and lignin, they are difficult to be directly digested and absorbed by animals. Animals will increase the burden on the intestines if they eat them, causing intestinal inflammation. disease. Fermented feed uses microorganisms a...
