To thoroughly implement the national deployment of "winning the battle for seed-industry revitalization" and "strengthening disease eradication," and to effectively address the seed-source health concerns that weigh heavily on breeding enterprises, on May 23 the Animal Husbandry and Veterinary Party Branch of the College of Animal Science and Technology, Zhongkai University of Agriculture and Engineering—led by the company's founder Prof. Cong Feng (Party Branch Secretary)—went to the production frontline of Guangzhou Jinbang Poultry Industry Co., Ltd. to carry out specialized avian leukosis testing and eradication technical services. With concrete actions they brought the laboratory "to the side of the incubator," building a solid "firewall" for the safety of the poultry seed industry and empowering seed-industry innovation with science and technology.
Avian Leukosis: An Invisible Killer of the Poultry Seed Industry
Avian leukosis is a vertically transmitted neoplastic disease caused by Avian Leukosis Virus (ALV), and is one of the major diseases troubling China's poultry industry. The disease can cause immunosuppression, growth retardation and decreased egg production in flocks, and can even induce tumors leading to death; there are currently no specific drugs or vaccines. Once a breeder flock carries the virus, it not only lowers production performance but also poses a serious threat to the health of downstream commercial chickens, bringing huge economic losses to enterprises.
Breaking Technical Bottlenecks: Meconium Testing Shows Its Power
Early diagnosis and eradication are effective means of avian leukosis prevention and control. Chick meconium testing, as the "first checkpoint" for establishing negative core flocks, has crucial detection efficiency and accuracy.
In this service, Prof. Cong Feng demonstrated his research team's latest optimization results in "avian leukosis meconium detection technology" in recent years. Addressing the pain points of traditional meconium testing—cumbersome operations and difficulty scaling up in large-scale farming—the researchers greatly simplified the operation process and improved detection efficiency through improved chick-separating tools, enabling high-throughput screening for industrial application.
Against the Clock: Daily Testing Volume Reaches a New High
In the incubation workshop of Jinbang Poultry, Prof. Cong Feng led the Party members and the company's technical staff to fight side by side, strictly collecting and processing chick meconium samples according to standards. The team members had clear divisions of labor, and the entire process—from sample collection, pre-treatment, ELISA testing, to chick selection—flowed smoothly.
After days of hard work, the team successfully completed accurate testing of nearly 5,000 meconium samples. In an on-site exchange, Prof. Cong Feng revealed: "After long-term process refinement and tool optimization, this high-throughput detection system is now very mature. In previous real-world applications, our technical team set an industry benchmark of 10,000 tests per day, and we are fully capable of undertaking the testing needs of large-scale breeding enterprises for whole-farm eradication."
Deep Industry-University-Research Integration: Safeguarding the "Guangdong" Seed Industry
This testing service was not merely a one-time technical output, but a vivid practice of the educational philosophy of "writing papers on the land of the motherland." A relevant person in charge of Guangzhou Jinbang Poultry said that avian leukosis eradication is a protracted battle, and the efficient testing scheme brought by the Party expert team from Zhongkai not only significantly reduced the enterprise's eradication costs, but also provided a scientific basis for the enterprise to establish negative core breeding flocks.
