Abstract: A cross-sectional study was conducted from November 2014 to August 2016 at Adama Municipal Abattoir and Bishoftu ELFORA Export Abattoir, Central Ethiopia, to estimate the prevalence and distribution of lesions of bovine tuberculosis on the basis of gross examination. On 1,896 cattle, a detailed postmortem investigation was used to conduct this study (1,266 from Adama and 630 from Bishoftu). A systematic random sample strategy was used to choose the study animals. An ante-mortem examination was used to investigate potential risk factors. Post mortem examination was done by examination of bronchial, mediastinal, retropharyngeal, mandibular, mesenteric and pre-scapular lymph nodes and palpation and then incision of organs such as the lungs, liver and kidneys. Descriptive statistics were used to summarize the prevalence of bovine tuberculosis and Chi-square (X2) test was applied to compare the infection status with regard to the hypothesized risk factors and (P<0.05) was set for statistical significance. The overall prevalence of bovine tuberculosis was 4.22% (80/1896) on the basis of gross TB lesions. Larger proportion (52.5%) of TB lesion was recorded in the respiratory pathway followed by lymph nodes of the head (26.25%), mesenteric lymph nodes (7.5%), pre-scapular lymph nodes (7.5%) and liver and hepatic lymph nodes (6.25%). The prevalence of the disease was statistically significantly (P<0.05) varying with origin of animal, location of abattoir and body condition score. In conclusion, the disease is ubiquitous in slaughtered cattle and is a major cause of liver condemnation at the Adama municipal abattoir and Bishoftu ELFORA export abattoir; further extensive investigations on the disease's epidemiology and strategic strategies to reduce the disease should be undertaken.
