Pigs with Atrophic Rhinitis have an increased risk for which common illness?

Pigs affected by Atrophic Rhinitis, a disease that causes lesions in the nasal passages and can lead to severe nasal distortion, are indeed at a heightened risk for pneumonia. This condition compromises the upper respiratory tract, making it difficult for the animal to effectively clear pathogens that could lead to pneumonia. The damaged nasal structures and the overall reduced respiratory function create an environment conducive to the growth of bacteria and viruses in the lungs. Consequently, as the pigs struggle to maintain normal respiratory health, they become more susceptible to infections such as pneumonia, which can further exacerbate their health issues and lead to significant economic losses in swine production.

The other options present common health issues in swine but are not directly linked to the complications arising from Atrophic Rhinitis in the same way that pneumonia is. This makes the connection between Atrophic Rhinitis and pneumonia particularly critical for understanding the broader implications of respiratory health in pigs.
