The serological methods were carried out using Rose Bengal Test (RBT) and indirect Enzyme-Linked Immunosorbent Assay (indirect-ELISA) in 300 beef. Results showed that 4.33% in individual prevalence for brucellosis, 30.43% in farms prevalence, 4.7% in a male beef, 4.18% in a female beef, and a male beef is more probable than a female beef (OR = 1.130, 95% CI = 0.339-3.774, P-value = 0.842). In addition, the prevalence was found that 5.21% in older three years old beef group, 1.42% in younger three years old beef group. Moreover, an older beef (> 3 years old beef group) is brucellosis more probable than a young beef (< 3 years old beef group) (OR = 3.798, 95% CI = 0.485 - 29.737, P-value = 0.204).thaมหาวิทยาลัยมหิดลโคเนื้อความชุกกาญจนบุรีbrucellosisbeefprevalenceKanchanaburiJournal of Applied Animal ScienceResearch Articleคณะสัตวแพทยศาสตร์ มหาวิทยาลัยมหิดล
