Major Gross Lesions of Lung in Cattle Slaughtered at Hawassa Municipal Abattoir, Southern Ethiopia

A cross-sectional study was conducted from November 2016 to April 2017, to estimate the prevalence of major gross lung lesions in cattle slaughtered at Hawassa Municipal Abattoir, southern Ethiopia. A total of 563 male cattle were examined by antemortem examination, while postmortem lung lesions were done using standard inspection procedures. Association between prevalence and the explanatory variables was estimated by way of chi-square/Fischer's exact tests using statistical packages for social science (SPSS) software. Upon postmortem examination, 96.6% (544/563) of cattle examined had various gross lung lesions. The most important lesions identified were hydatidosis, emphysema, congestion, and atelectasis with prevalence of 45.3%, 19.2%, 18.1%, and 6.4%, respectively. Based on origins of slaughtered animals, hydatid cyst, emphysema, and congestion were common in cattle that came from Tula area with prevalence of 46.3%, 20.4%, and 20%, respectively. The animals from Arsi-negelle and Hawassa were mostly affected by hydatid cyst with prevalence of 44.4% and 42.5%, respectively. Statistically significant association ( p = .038) was observed between prevalence of atelectasis and body condition of slaughtered cattle. In conclusion, the prevalence of hydatidosis was the major lesion in the lung of slaughtered cattle at Hawassa Municipal Abattoir. Therefore, appropriate disease control strategies should be put in place.
