Retrospective study of anatomopathological changes founded in the post mortem examination of bovine animals in Manaus, Amazonas, Brazil slaughterhouses, in the period of July 2017 to July 2018

The objective of this study was to conduct a retrospective study from July 2017 to July 2018 on the anatomopathological changes observed in post-mortem examination in slaughterhouses in Manaus-AM. Among the evaluated organs, 23% of the pieces were found to be condemned, with 54.29% represented by lung condemnations, followed by 12.78% of legs, 9.91% of kidneys, 5.20 % of head, 3.44% of intestines, 3.06% of tongue, 2.58% of heart, 1.39% of stomachs and 1.31% of livers. The organs with the greatest number of convictions were lungs and paws, and possibly these convictions occurred due to failures during pre-slaughter or even during slaughter.
