URSOLIC ACID HAVING ANTI-BACTERIAL ACTIVITY AGAINST CAUSATIVE BACTERIA OF PORCINE RESPIRATORY DISEASE COMPLEX AND USES THEREOF

摘要

The present invention relates to an antibacterial composition containing ursolic acid as an active ingredient for inhibiting livestock pathogenic bacteria, especially, to an antibacterial composition for inhibiting Actinobacillus pleuropneumoniae, Pasteurella multocida A, or Pasteurella multocida D, which is a pathogen causing porcine respiratory disease complex, and to a livestock feed additive and livestock feed containing the composition as an active ingredient. The antibacterial composition containing ursolic acid as an active ingredient for inhibiting livestock pathogenic bacteria of the present invention can be utilized as alternative antibiotics, and can be industrially very useful since the ursolic acid is mass-produced in the process of producing apple or persimmon processed products but mostly produced from peels, which are just discarded byproducts.
