Comparison of Chicken Performance Tests in Korea, Japan, and the United States

Performance testing in poultry, including laying performance, growth rate, and health status, is crucial for breed improvement and maintenance. While there is little data related to the performance test for broilers, other Korean chicken breeds (layers), as well as Japanese and American layers, are actively tested. This study aims to compare the chicken performance testing among Korea, Japan and the United States. The testing systems, evaluation criteria, and methods were compared, and the current state and issues of Korean chicken performance testing were investigated. Japan and the US have well-established, standardized performance testing systems with regular evaluations and detailed data analysis, leading to continuous and substantial breed improvement. Specifically, American layers undergo the North Carolina Layer Performance and Management Tests conducted by North Carolina State University, while the Japanese laying hen performance test is conducted upon application from farmers and companies in accordance with different prefecture’s laws. Conversely, Korea lacks sufficient performance testing, which results in slower and less efficient breeding, falling short of the systematic approach and robust data management observed in Japan and the US. To improve Korean chicken performance testing, it is essential to establish a systematic and standardized testing system similar to those in Japan and the US. Government and institutional support are crucial for implementing regular testing and comprehensive data analysis, which will facilitate significant breed improvement. Enhancing Korean chicken performance testing will greatly increase their competitiveness and ensure sustainable and long-term breed improvement.
