Cross-sectional study of seropositivity, lung lesions and associated risk factors of the main pathogens of Porcine Respiratory Diseases Complex (PRDC) in Goiás, Brazil

Table 3 Results of the pulmonary evaluations of 900 pigs at slaughter related to the percentage of Mycoplasma-like lung lesions areas and pleuritis, as well as the classification of the herds evaluated for PI. The animals were from commercial herds in the state of Goiás, Brazil (2016/ 2017)

*Herds with pneumonia indexes of up to 0.55 were considered free of pneumonia (Grade 0). Herds with indexes between 0.56 and 0.89 obtained an intermediate classification (Grade 1), in which the presence of pneumonia occurred but did not characterize a threat to the herd. Herds with indexes above 0.90 were considered with severe occurrences of pneumonia in the herds (Grade 2)
