Professor Changxin Wu graduated from Beijing Agricultural University with a major in Animal Science in 1957, and has been a faculty member of the university (now called China Agricultural University) since then. He did his further study on animal genetics and breeding at Institute of Animal Genetics, Edinburgh University, Scotland, U.K. (1979-1981). After returning to the home school, he was promoted to the rank of associate professor in 1983, and full professor in1988. He was appointed as the head of the Department of Animal Science from 1983 to 1987, and the dean of the College of Animal Science and Technology from 1993 to 2004. He is now an academician of the Chinese Academy of Sciences, the highest honour in scientific community in China.
Professor Wu became a member of WPSA in 1988 and was a key founder of WPSA China Branch, which is now one of the largest branches of WPSA. He served as the Secretary from 1990 to 1997 and the Chairman of China branch from 1997 to 2004. He also served as a Committee member of Asia-Pacific Federation of WPSA from 1988 to 2004. He attended the World’s Poultry Congress in 1988, 1992, 1996, 2000, 2004 and 2008. He was a keynote speaker on “Genetic changes affecting poultry production in China” during WPC 2000 in Montreal, Canada. He organized a satellite conference on waterfowl in Beijing just after WPC 1988, Nagoya, Japan. Now, he is the chairman of scientific committee of the 25th World’s Poultry Congress to be held in Beijing in 2016.
In the fields of poultry science, he advanced the theory and method of “synthetic line breeding system” in layer instead of “closed flock breeding system” which was used for a long-time in the layer breeding in China, and the performance of layer was improved by using the new method. The achievement was awarded the 2nd class prize by the Ministry of Agricultural of China in 1992. Recognizing the need of more efficient layers, he started to explore the use of dwarf gene in layer breeding. After 8 years’ research work, along with his colleagues, he successfully developed pure line and commercial layer with dwarf gene. The miniature layers have lower body weight and less feed intake, and the feed conversion rate is about 2:1. The achievement was awarded the 2nd class prize for the National Advances of Science and Technology by the Chinese Government in 1999. Now the miniature layers have been popularized about 80 million each year all over the country. Now he is doing the research on genetic mechanism of hypoxia adaptation in Tibet Chicken and published a copy of “Physiology and Genetics of Adaptability to Highland Hypoxia in Tibetan Chicken” in 2012.
He has also paid attention to conservation and utilization of animal and poultry genetic resources. Molecular biotechnology, experimental animal simulation and geographical information system were used in the conservation of animal and poultry genetic resources. Problems such as the effective population size, the length of generation interval, the optimum sex ratio and allowable inbreed level in a conserved population were solved properly. The achievement was awarded the 1st class prize by the Ministry of Agricultural of China in 1999 and the 2nd class prize by the State Council of China in 2001 as well. About the utilization of Chinese native chicken breeds, he has done a lot of organization and extension work through so called “academician work station” on his name. For instance, Wenshang stripe feather chicken in Shandong Province, Jingmen blue egg shell chicken in Hubei Province, Dongxiang blue egg shell chicken in Jiangxi Province and Huiyang bearded chicken in Guangdong Province. The economic traits such as egg number, egg shell quality, growth rate have been improved under his advice.
In education, he is an excellent teacher for undergraduate students as well as graduate students. He has given the course of Animal Genetics, Biostatistics, Animal Breeding and Population Genetics for undergraduate students and Quantitative Genetics, Comparative Animal Breeding, and Modern Progress on Animal Breeding for graduate students. Because of his excellent teaching and education, the State Council gave him an honour certificate of Excellent Contribution on Development China’s High Education in 1991. As the editor in chief, he compiled and published Animal Genetics in 2015 and Animal Biology in 2016. Up to now, more than 100 students have received PhD or master’s degree under his guidance, among them 43 got Master degree and 76 got PhD degree including 1 member of British Royal Society and 1 academician of Chinese Academy of Engineering.
