Histopathological study and pulmonary classification of bovine lesions

Abstract

The partial or total seizures of carcasses or organs by veterinary services during inspection constitute a real 
constraint for butchers from the economical point of view. Results of a study carried within two years in Tiaret 
slaughterhouse (west of Algeria) and within three years in Batna slaughterhouse (east of Algeria) have shown a high 
frequency of pathological pulmonary lesions in 870 bovine lungs that were inspected. 744 lungs were concerned by 
these lesions. The seasonal impact of the lesions has been highly marked. The hydatid cyst was the most frequently 
observed lesion with 330 cases (42.64%) followed by pulmonary emphysema with 111 cases (14.35%) and pulmonary 
congestion with 61 cases (7.89%). According to the localization of these lesions, we have noted that the right lung was 
the most affected (92.60%) than the left one, and the cranial lobes were more attacked (76.90%) than the caudal ones 
(71.45%).
