Lungs exposed to larval stages of cestode belonging to the genus Echinococcus caused Hydatidosis which is an important zoonosis and may lead to development of emphysema and pneumonia as a result of secondary disease complication. A cross-sectional study was conducted from May, 2021 to August, 2021 to determine the major gross lesions and associated risk factors in small ruminants that brought from Afar, Arsi, Borena, Harar and Somali areas at ELFORA export abattoir. During the study period, gross pathological examination was conducted on 400 (224 goats and 176 sheep) randomly selected small ruminants. The total prevalence of gross pathological lesions in lung of Sheep and Goats slaughtered at ELFORA export abattoir in the current study was 250 (62.5%). Out of 224 goats 143 (63.84%) and 176 sheep 107 (60.79%) lung gross lesions were detected. Based on ages of the small ruminants, in young 58(69.87%) and adult 192 (60.56%) were affected with gross pathological lesions of lungs. Based on body condion score, good 59 (52.67%) and medium 191 (66.31%) were affected with gross lesions of lung. Animals were brought from Borena, Arsi, Somali, Harar and Afar within percentage of gross lesions that detected in the lungs 81 (60.9%), 36 (67.92%), 37 (62.71%), 37 (74%) and 59 (56.19%) respectively. Significant variation (p < 0.05) was no observed in different age groups, species, body condition scores and origin of the animals. The current finding in goats, hydatid cyst (8.93%), pneumonia (20.98%), empsema (16.07%), calcification (14.73%), congestion (10.27%), consolidation (8.93%), abscess (3.57%) and others (6.25%) while in sheep, hydatid cyst (11.93%), pneumonia (23%), empsema (13.63%), calcification (13.63%), congestion (6.25%), consolidation (5.68%), abscess (5.11%) and others (2.27%) prevalences were determined. In conclusion, this study showed that hydatidosis and major gross pathological lesions of lungs in small ruminants causes significant problems generally on health of small ruminants and particularly on organ of lungs. Further investigation to determine prevalence of lung abnormalities in small ruminants in different areas of the country and zoonotic importance of hydatidosis is recommended.
