On November 18, the Institute of Animal Sciences of the Chinese Academy of Agricultural Sciences published a significant research paper in the prestigious international journal Advanced Science. This study marks the first systematic analysis of metabolic biomarkers and genetic regulatory mechanisms associated with mortality risk in white-feathered broilers. These findings provide a critical scientific basis for enhancing disease resistance and optimizing domestic breeds. The "Guangming No. 2" breed, independently developed by Guangming Bio, serves as a prime example of these findings in practice, demonstrating superior adaptability, higher survival rates, and stable metabolic health.
While long-term breeding has significantly improved the growth rate and production performance of white-feathered broilers, rapid growth often puts the metabolic system under high-load stress. This can lead to metabolic dysfunction and increased mortality, posing a challenge to the sustainable development of the industry.
By integrating multi-omics data through a "metabolome-genome-physiological state" analysis, the research team established a causal chain from metabolic disorder to mortality risk. The study revealed a "homeostatic remodeling mechanism" of metabolic networks under high stress. Key findings include:
The Future of Breeding The industry is shifting its focus from "rapid growth" to "health, stability, and low risk". Disease resistance and metabolic homeostasis are becoming the core competitive factors for future breeds. As a nationally approved representative breed, "Guangming No. 2" prioritized health and resilience from its inception. Having won top science and technology awards and achieved the first export of grandparent stock in 2025, the breed's success validates the scientific focus on metabolic and immune stability.
