Which clinical sign is associated with Pseudorabies in grower and finisher pigs?

Pseudorabies, caused by the Suid herpesvirus 1, often presents with a range of clinical signs in swine, particularly in grower and finisher pigs. Respiratory issues are a hallmark of the disease, as the virus primarily affects the respiratory tract, leading to symptoms such as sneezing, nasal discharge, and labored breathing.

Infected pigs may show signs of pneumonia, which is a common complication associated with the disease. The virus's effects on the respiratory system often manifest as cough and increased respiratory effort, making respiratory problems the most characteristic clinical sign in this age group.

While vomiting, skin lesions, and behavioral changes can occur with various other diseases, they are not specifically associated with Pseudorabies in this context. Understanding the predominant respiratory issues helps in the diagnosis and management of the disease in affected swine populations.
