Porcine circovirus-associated disease (PCVAD) is a health condition affecting pigs, primarily caused by the porcine circovirus type 2 (PCV2). This virus can lead to various symptoms, including weight loss, respiratory issues, and skin lesions. PCVAD is particularly concerning in young pigs, as it can significantly impact their growth and overall health. The disease can manifest in different forms, such as post-weaning multisystemic wasting syndrome (PMWS) and porcine dermatitis and nephropathy syndrome (PDNS). Effective management strategies, including vaccination and biosecurity measures, are essential to control the spread of PCVAD and minimize its impact on pig farming.
