Abstract
Bovine mastitis is one of the most common diseases causing losses to the dairy industry. To reduce the use of antibiotic for treatment of this disease, essential oils (EOs) have high potential to apply in the field without any harmful chemical sanitation for raw milk. In this study, the antibacterial effect of Cinnamon cassia, Chenopodium ambrosioides and Litsea cubeba EOs against bacteria isolated from bovine mastitis were investigated. Among the three EOs, C. cassia EO showed the strongest antimicrobial activity against all tested bacteria. Moreover, the combination of C. cassia-C. ambrosioides and C. cassia-L. cubeba showed a significant synergistic effect with the total FIC value from 0.5 to 0.75, lower the MIC by 2 to 4 times. Those results suggested that EOs could be used to reduce lower the concentration used, minimum effective dose of the drugs and to replace the antibiotic treatment for bovine mastitis in the future.
