Jilin University Department of Agronomy, recently held a news conference to announce the world's first "with anti-cloning of classical swine fever virus in pigs" cultivate successful, this indicates that China classical swine fever virus in transgenic breeding areas have reached international advanced level.
It is understood that since 1933 in the United States, Ohio, discover classical swine disease, classical swine fever has been a threat to the world's most serious pig diseases each year to one of the countries up to billions of dollars of losses. For example, in China
Every year of the pig of around 10 million head, pig mortality exceeds 10%, the death of the first big reason is that classical swine fever, direct economic losses as high as $ 40 billion. "Anti-cloning pigs against classical swine fever" was born, as the world's largest pork producer and consumer countries of China, of great significance. In the actual process of aquaculture production, can reduce inputs, reducing costs. At the same time, this clone pigs on human health has no effect, and more conducive to food security.
Then, in the birth of Jilin University Department of Agronomy's first "world with anti-cloning of classical swine fever virus in pigs" what experience behind?
In August 2004, the Chinese people's Liberation Army quartermaster general University, Jilin University, transfer to the district into established the Jilin University Department of Agronomy. Was first established, agricultural Department will establish a "struggle to find ways to retain talent, talent introduction, at all costs by hiring talent" talent team building ideas. Successful cultivation of the "anti-cloning pigs against classical swine fever," ABC's Chief Scientist Lai Liang and scientists spreads the Changchun, plums, Ouyang red, is in this way has been invited to the Department of Agronomy, Agronomy Dept., appointed to the left to the Department of Agronomy. Since then, Jilin University of Agronomy Dept. conscientiously implement the scientific development concept, in a short period of two years is achieved by leaps and bounds. Faculty has invested nearly $ 10 million to build a research platform, improved the research environment, to foster the "anti-cloning pigs against classical swine fever" to lay a good foundation.
Cultivate the "anti-cloning pigs against classical swine fever," is an extremely complex system research projects. This issue relates to the basis of clinical veterinary science, veterinary medicine, preventive veterinary medicine, zoology, molecular biology, Molecular Virology, zoology, animal breeding and reproduction of eight disciplines.
According to the Chief expert, Professor, the subject is in the National Science Foundation funding collaborative research. They will be able to inhibit the swine fever virus for gene transfer to the "Chinese experimental swine" fetal fibroblasts, precursors within nuclear transfer preparation pig cloned embryos, and then transplanted to Duroc surrogate mother pigs. From the Research Division, areas can be divided into three technical links, first filtered out of the gene, classical swine fever virus and then filtered against classical swine fever virus genes into cells, and finally the somatic embryos of tectonic and transplantation. The entire cultivation process flow, any part of the problem, all need to start over. Only filter on classical swine fever virus genes that a scientific aspect of the workload, it is the equivalent of a doctoral dissertation completion of workload, generally require the time of the last two years, in which it's hard to imagine. In the third part, they have done 10 head receptor pig (surrogate mother pigs), the first 8 head.
September 5: 40 p.m. to 7: 10 p.m., in the original kind of Jilin University, a pig farm Duroc surrogate pregnancy sow in 114 days after smooth output three head healthy cloned piglets, weight 1050 grams respectively, 1100 grams and 550 grams. After genetic testing piglets cells confirmed that the "clone pigs" cells with the transferred gene against classical swine fever virus. 4 October, a receptor is a smooth production pigs.
Professor Ouyang red said, the subject of success also integrates other research personnel of wisdom and strength. To the subject, there have been more than 40 graduate students and doctoral candidates to participate in the work, of which 10 000 students also participated in the core work. Jilin University Institute of animal husbandry and veterinary medicine of clinical veterinary science teacher, Xie-hung has 10 times successfully completed the receptor of surgery porcine.
Jilin University Presidents, Assistant Secretary of the Communist Party of the Ministry of agriculture, Science Minister professor said that Korean Yu, the subject of study in depth. The current discussion group is detected with the clone pigs against classical swine fever virus into the gene, further anti-HCV test, large-scale breeding and expanding population, must be subject to the relevant State departments of inspection and quarantine, this process also requires 3 to 5 years, technology will further mature. That's when the pig will no longer be affected by the disease, classical swine fever will greatly improve the pig's economic and social benefits.
