摘要

The present invention relates to an antimicrobial composition for the inhibition of livestock pathogenic bacteria containing ursolic acid as an active ingredient, in particular to a method for producing a microorganism capable of inhibiting the growth of actinobacillus ( Actinobacillus,pleuropneumoniae , / RTI PasteurellaThe present invention relates to an antimicrobial composition for suppressing multocida A or passtralla mushroom D, and to a livestock feed additive and a livestock feed containing the composition as an effective ingredient. The present invention relates to a livestock feed additive for livestock pathogenic bacteria The antimicrobial composition can be utilized as an alternative antibiotic, and it can be very useful industrially because it can produce uric acid from a shell, which is a by-product, which is generated largely in the process of producing processed products such as apple or persimmon.
