Abstract
A cross-sectional study was conducted from November 2015 to April 2016 on male cattle slaughtered at Gondar ELFORA abattoir, Northern west Ethiopia, to examine the major gross lesion and its prevalence among different risk factors in lung and livers. The pulmonary hepatic lesions were diagnosed on the basis of pathological findings. During the post mortem examination, out of the total 740 male cattle destined for slaughter (648, 87.5%) of cases were found positive for different pathological lesions (lung and liver). Out of this (397, 53.6%) of lung and (251, 33.9%) of liver were found to have lesions. Among major gross pulmonary lesion encounterd in lung were Hydatidosis (50, 6.8%), emphysema (70, 9.5%), congestions (65, 8.8%), hemorrhage (47, 6.4%), Athelectasis (38, 5.1%), calcified nodules (50, 6.8%) and more than two lesions 48(6.5%). Among these lesions emphysema (70, 9.5%) and congestion (65, 8.8%) were the most frequently observed lesion and abscesses were the least frequently encountered lesion (29, 3.9%). This study also investigates the major gross hepatic lesion in the study area. Accordingly, Fasciolosis (90, 12.2%), Calcification, (69, 9.3%), Hydatidosis (24, 3.2%), Abscess (25, 3.4%) and two and above lesions (24, 3.2%) were the major hepatic lesion observed during the study. The statistical analysis showed that there was statistical significance (P<0.05) between the prevalence of pulmonary lesion among age and body conditions. The prevalence of hepatic lesion was also found to be significant with the origin and body condition of the study animals (P<0.05). The results of this study showed that pulmonary emphysema and hepatic fasciolosis were more pronounced recorded lesion in lung and liver respectively. Therefore, better livestock management system, good meat inspection and creating awareness on butchers and cattle trader should go in a long way to reduce the problem in the abattoir.
