Embodiment
[0021] Embodiment A kind of preparation method of novel hepatoprotective microbial fermented protein pig feed, comprises the following steps:
[0022] (1) Prepare 100kg of probiotic strains;
[0023] (2) Weigh sucrose or glucose glucose 3.5, peptone 1.5, beef extract 1.0, sodium chloride 0.8, ammonium sulfate 0.6, potassium dihydrogen phosphate 0.075, yeast extract 0.5, magnesium sulfate 0.04 by weight (kg), add distilled water 100mL, Adjust the pH to 7.1, sterilize at 121°C for 40 minutes, prepare a seed liquid medium, and inoculate probiotic strains for cultivation;
[0024] (3) Expand the seed solution cultivated for 2 days for 1 day;
[0025] (4) Mix the expanded cultured bacteria liquid, 250kg of inland cottonseed meal, 150kg of DDGS, 80kg of soybean hulls, 25kg of molasses and tap water, and transfer them to a solid-state fermentation tank for solid-state fermentation;
[0026] (5) After the fermentation is over, the fermented microbial fermented protein pig feed wet m...
