Establishment of age-specific intervals based on the hematological and immunological parameters of commercial pigs in the Republic of Korea

Abstract

Health monitoring based on hematological and immunological parameters is crucial for optimizing performance in the swine industry. This study was conducted to address the lack of comprehensive reports on these parameters in commercial pigs in the Republic of Korea (ROK). To fill this gap, blood samples from 764 healthy pigs across 32 farms in the ROK were analyzed, with the pigs categorized into specific age groups, including weaners, growers, finishers, gilts, and sows. Complete blood counts (CBC) and immunoglobulin G (IgG) concentrations were measured, revealing significant differences across all age groups (p<0.0001). These findings allowed us to establish age-specific Reference Intervals (RIs) at a 95% confidence level and Confidence Intervals (CIs) at a 90% confidence level for each group. This study provides robust guidelines for evaluating the health status of commercial pigs at different stages of growth and development in the ROK. The established RIs and CIs offer valuable insights for future research and practical applications, ensuring reliable health assessments. Routine monitoring of these parameters represents a critical tool for early detection and improved health management in commercial pig populations.
