Solid-state fermentation of corn-soybean meal mixed feed with Bacillus subtilis and Enterococcus faecium for degrading antinutritional factors and enhancing nutritional value

Table 1 Effect of fermentation on the concentration of soybean antigenic protein, as air-dry basis

^aDegradation rate = soybean antigenic protein content in uninoculated feed – soybean antigenic protein content in inoculated feed) / soybean antigenic protein content in uninoculated feed × 100%
^bUninoculated feed: sterile medium was added to mixed feed (45% corn, 45% soybean meal and 10% wheat bran) instead of inoculated bacteria, other experimental procedures were the same as those of inoculated mixed feed
^c B. subtilis: mixed feed was inoculated with B. subtilis and fermented at 37 °C for 24 h
^d B. subtilis and E. faecium: first-stage fermented (B. subtilis) mixed feed was inoculated with E. faecium and incubated under anaerobic conditions at 37 °C for 48 h
