Evaluation of Pulmonary Lesions in Slaughtered Fatteners as Indicators of Respiratory Diseases in Pigs

The goal of this research was to identify lung lesions in slaughtered fatteners originating from registered farms. Evaluation of lung lesions was based on their visible macroscopic features, which were then associated with corresponding diseases. Data on lung lesions in slaughtered fatteners were collected over the period spanning from October to December 2022 from three slaughterhouses (A, B, C), involving 150 fattening animals from each slaughterhouse. The examination of slaughtered pig lungs from all three slaughterhouses in our study revealed that Mycoplasma hyopneumoniae lesions in the lungs are the most prevalent, while Actinobacillus pleuropneumonia and bronchopneumonia occurrences are rare.
