The invention discloses a method for forming normal healthy functional bacterial flora in intestinal tracts of newborn piglets in the early period. The method includes the steps of preparation of a primary birth canal bacterial liquid, preparation of a birth canal bacterial liquid for inoculation, grafting of birth canal bacterial flora into the newborn piglets, preparation of a primary coprophilous bacterial liquid, preparation of an intestinal bacterial liquid for inoculation and grafting of the intestinal bacterial liquid into the newborn piglets. According to the method, a normal healthy micro-ecological environment of the intestinal tracts of the newborn piglets can be created quickly, the growth of immune systems of the newborn piglets is stimulated, diarrhea can be effectively prevented from happening to the piglets, and the incidence rate of diarrhea of the piglets can be controlled within 3%; growth and reproduction of pathogenic microorganisms in the intestinal tracts can beeffectively suppressed, and diarrhea of the piglets is efficiently and thoroughly prevented and treated. Meanwhile, the normal healthy bacterial flora formed in the intestinal tracts in the early period can promote the growth and development of the newborn intestinal tracts, facilitate function exertion and shorten a suckling period, the weaning age of the newborn piglets can be changed to 21 daysold or even earlier from 28 days old, and weaning of the piglets in the early period can be achieved.
