Most Brazilian states have common features, as the problems that affect the health of animals. Infectious and contagious diseases, parasites, and metabolic deficiencies, are of great importance, directly interfering in economic indicators. Respiratory diseases have highlighted the various systems of breeding cattle, because they have lung particular characteristics making them more vulnerable to diseases of the respiratory system. There are no confirmed reports that in feedlot of dirt would be a case of pneumonia higher compared to other systems to create due to the high population density, stress and dust. Therefore, the objective of this project is to assess the level of changes in lung tissue of cattle Nelore finished under confinement conditions compared to the finished under grazing. We used 96 animals, 48 animals raised on pasture (AP) and 48 animals from confinement (AC). These were identified in the corral of waiting, with the slaughter line and perform a collection of fragments of the cranial lobe and the median on the ramp inspection. The samples were fixed in buffered solution of formol 10%, preserved in alcohol at 70% and histological processed, making the color of slides with hematoxylin and eosin (H&E) and the optical microscope analysis. Initially the data were submitted to descriptive statistics and later to the chi-square, Wilcoxon and Mann-Whitney. None of the evaluated parameters was influenced by the different lobes and different systems of termination
