The invention discloses a
fermentation broth used for preventing
diarrhea of weaned
hybrid piglets between Berkshire pigs and Min pig as well as a preparation method thereof. The
fermentation broth used for preventing
diarrhea of the weaned
hybrid piglets between the Berkshire pigs and the Min pig is prepared from the following raw materials: pilose asiabell roots, radix astragali, radix platycodonis, bighead atractylodes
rhizome, malt, hawthorn fruits, Mongolian
dandelion herb, Chinese pulsatilla roots, water, and
lactic acid bacteria. The preparation method of the
fermentation broth especially comprises the following steps: step one, crushing the pilose asiabell roots, the radix astragali, the radix platycodonis, the bighead atractylodes
rhizome, the malt, the hawthorn fruits, the Mongolian
dandelion herb and the Chinese pulsatilla roots, so that crushed
plant powder is prepared; step two, putting the crushed
plant powder, the
lactic acid bacteria and the water into a fermentation tank so as to carry out constant-temperature culturing, so that the
fermentation broth is obtained. The
fermentation broth disclosed by the invention is obtained by fermenting natural plants with the
lactic acid bacteria, so that the traditional technologies of decocting, cooking, simmering, refining,
steaming and soaking are changed by the fermented traditional Chinese medicines; thus, the medicinal properties are changed, and
medicine effects are greatly improved. The
fermentation broth is capable of improving non-
specific immunity of the piglets to a certain extent, and has preventive effects on
diarrhea of the
weaned piglets.
