In Changsha—the "Star City" and birthplace of a great historical figure—the 5th T50 Technical Symposium for the Breeding Poultry Industry, organized by Ringpu Bio, concluded successfully on October 31. Key representatives from 81 breeding poultry enterprises across China—collectively managing a stock of approximately 90 million breeder hens—gathered to focus on the theme: "Joining Forces, Safeguarding Defenses, Stabilizing Production, and Looking Toward the Future." The event brought together senior university professors, veteran veterinary experts, and Ringpu Bio’s core technical team. Together, they addressed critical issues such as disease risks in poultry breeding, biosecurity, immunosuppressive diseases, and emerging pathogens. Through the five dimensions of "production, academia, research, application, and iterative improvement," participants exchanged research findings, academic insights, and actionable disease prevention and control strategies, all aimed at fostering stable production and enhanced efficiency within the poultry industry. ...

Professor Jia Weixin from South China Agricultural University delivered a specialized presentation titled "Latest Epidemiological Trends of Avian Influenza in 2026 and Response Strategies." He analyzed the global situation, noting that the 2026 outbreak of highly pathogenic avian influenza (HPAI) is more severe than in the same periods of the previous two years; while concentrated in Europe, the virus has now spread across every continent. Regarding domestic surveillance, he reported that all H5 strains circulating in 2026 belong to Clade 2.3.4.4b, with the b5.5 sub-lineage being the dominant strain. Furthermore, since late 2025, a European-like b5.6 sub-lineage has emerged in regions including Hebei, Shandong, and Henan, with its geographic reach continuing to expand.
Meanwhile, the number of H7N9 isolates has dropped significantly, though the strains continue to diversify, and H9N2 prevalence is characterized by the alternating dominance of the B4.7.2 and B4.7.3 sub-lineages.
Finally, he offered recommendations for disease prevention and control: continuously strengthen proactive surveillance and the tracking of viral mutations, while proactively stockpiling vaccines matched to circulating strains. Poultry farms should establish a "proactive surveillance + active immunization" mechanism, ensuring comprehensive defense against both highly pathogenic and low-pathogenic avian influenza. ... Liu Yijun, a senior technical expert from the Solutions Department at Ringpu Bio, delivered a presentation titled "Analyzing the Causes of Declining Fertility, Hatchability, and Chick Quality in the Late Laying Period, and Scientific Countermeasures." He clarified the interrelationships among these three key performance indicators and the value of "egg-breakout analysis" (examining unhatched eggs). He systematically outlined the various factors contributing to these declines—including issues with roosters (body weight, uniformity, and health), hens (nutrition and gut health), hatching egg management (collection, disinfection, storage, and transport), and incubation management (temperature, humidity, ventilation, and egg turning). He proposed scientific interventions, emphasizing the need to start at the source—the breeder flock—by managing the body weight and uniformity of both roosters and hens, standardizing the handling of hatching eggs, and precisely optimizing the incubation environment based on the specific embryonic developmental stage at which mortality occurs. Through meticulous management across every stage, the quality of hatched chicks can be improved.
Dr. Wang You, head of the Solutions Department at Ringpu Bio, concluded the session with a report titled "Gaining Insight into Emerging Disease Risks and Strengthening Defenses." Based on an analysis of large-scale epidemiological data, he identified Infectious Bronchitis Virus (IBV), *Mycoplasma synoviae* (MS), and Marek’s Disease Virus (MDV) as the most prevalent diseases currently, while highlighting the need for focused attention on emerging threats such as the H6 subtype of avian influenza, chicken-origin flaviviruses, and chicken-origin *Riemerella anatipestifer* (duck plague/septicemia) infections. Furthermore, an in-depth analysis was conducted on the risks posed by key emerging infectious diseases. In the realm of avian influenza, H5 subtypes—including b5.5, b5.6, and various mutant strains—are now co-circulating, accompanied by a shift in host distribution (with an increased prevalence in chickens and quails). H6 isolates have shown a significant rise in detection rates and exhibit slightly higher pathogenicity than H9, while the 4.2.5C4 lineage remains the dominant strain of H9. Additionally, the chicken-origin flavivirus (Tembusu virus) has crossed the species barrier from waterfowl to chickens; it is capable of vertical transmission and is frequently misdiagnosed. Similarly, *Riemerella anatipestifer* (typically associated with ducks) has breached the host barrier—with a detection rate of 13.9% in chickens—causing oviduct impaction and a triad of inflammatory conditions ("three-itis"). Finally, the Poultry Solutions Department at Ringpu Bio was introduced, highlighting its systematic response framework. Leveraging a specialized service model—comprising "professional diagnostics, monitoring and early warning, scenario-based disease research, and a closed-loop value-added service system"—the department utilizes 10 epidemiological surveillance zones and over 600 professional staff members to cover major poultry-farming regions nationwide. By providing comprehensive solutions—including tailored immunization programs, biosecurity protocols, and precision medication strategies—the company helps poultry enterprises improve performance metrics, mitigate risks, and enhance overall profitability.
