Preparation method and application of ginger seedling fermented feed for sows

A preparation method of ginger seedling fermented feed for sows, comprising following steps:

• S1, crushing and pressurizing ginger seedlings to obtain crushed ginger seedling material with a moisture content of 70-75% and ginger seedling juice;
• wherein a moisture content of the ginger seedlings is 85-90%, and a particle size of the crushed ginger seedling material is 1-10 mm;
• S2, adding bran into the crushed ginger seedling material to adjust the moisture content to 60-65%, adding an inoculum composed of Pediococcus lactis, Saccharomyces cerevisiae and Bacillus subtilis in equal mass ratio and compound enzyme comprising pectinase, cellulase and hemicellulase in equal mass ratio, and performing anaerobic fermentation for 7-14 days at a temperature not higher than 50°° C. to obtain ginger seedling biological feed;
• wherein the mass ratio of the crushed ginger seedling material, the compound enzyme and the inoculum is 100:0.1-1:0.1-1;
• S3, adding molasses and inoculum into the ginger seedling juice, and performing anaerobic fermentation for 7 days to obtain fermented ginger seedling juice;
• wherein the mass ratio of the ginger seedling juice, the molasses and the inoculum is 100:2-5:0.1-1;
• S4, using the fermented ginger seedling juice to adjust the moisture content of a basic diet to 40-45%, and performing anaerobic fermentation for 4-5 days to obtain fermented ginger seedling juice concentrated feed;
• and
• S5, uniformly mixing the ginger seedling biological feed, the fermented ginger seedling juice concentrated feed and premix to obtain the ginger seedling fermented feed for sows;
• wherein in percentage of 100% of the ginger seedling fermented feed for sows by mass, the mass percentage of the ginger seedling biological feed is 30-50%, the mass percentage of the fermented ginger seedling juice concentrated feed is 50-65%, and the mass percentage of the premix is 5%.
