Feed additive with complex microorganisms for piglets

The invention relates to the field of complex microorganisms, in particular to a feed additive with complex microorganisms for piglets. The feed additive consists of candida utilis, enterococcus faecalis, lactobacillus acidophilus and bacillus subtilis, and then all the raw materials are cultured in culture medium containing 5-10 percent of epimedium herb for 60-72 hours at the temperature of 35-37 DEG C to obtain culture, namely the feed additive. According to weight part, the candida utilis : enterococcus faecalis : lactobacillus acidophilus : bacillus subtilis is equal to 1-3:1-3:1-3:1-3. The feed additive has multiple nutrient component, oregano extract has the functions of sterilization, bacteriostasis and oxidation resistance, can well inhibit the diarrhea of the piglets, enhance the immunity of the piglets, reduce the death rate and lower the cost.
