This study systematically analyzes the genetic stability and phenotypic evaluation framework of transgenic livestock, providing a comprehensive overview of key technologies for phenotypic data collection and analysis. It focuses on the integration patterns of exogenous genes within host genomes, the effects of copy number variation, and the stability of gene expression across generations. Through case studies on transgenic cattle and pigs, the research reveals a strong correlation between genetic stability and phenotypic consistency. The results indicate that combining non-viral vectors with gene-editing technologies not only facilitates long-term stable gene expression but also effectively ensures physiological health and production reliability in livestock. This study offers a solid theoretical foundation and methodological support for the safety assessment and industrial application of transgenic livestock.
