Each broiler in the breeding house is equipped with an individual identification device, and next to it is an automatic feed to gain detection device for the broiler. The Internet of Things and big data technology give each broiler a unique "smart identity tag". Even the feed intake and weight gain of each broiler at different growth stages can be accurately recorded...
At the end of November, the reporter participated in a week-long "high-quality development research tour" theme interview activity, and saw the technical content of "eating chicken" in the fields of Changsha and Changde, Hunan Province, in the factory assembly line and the laboratory of researchers.
Technicians test chicken meat at a laboratory in Shimen county, Changde, Central China's Hunan province, Nov. 29, 2019.
Zhang Haihan, a professor of poultry breeding at Hunan Agricultural University, told reporters that at present, the main broiler categories in China are white and yellow feather broilers. Among them, white-feather broilers occupy most of the market, and yellow-feather broilers are preparing to open a new situation. He mentioned that the future trend of yellow-feathered broilers is cold fresh, not live birds.
"Our school has established a deep school-enterprise cooperation model with enterprises, committed to the scientific and technological innovation and technology research and development of the whole industrial chain of high-quality chicken, deep cultivation of high-quality chicken breeds and germplasm innovation, after nearly 10 years of unremitting efforts, we have established a perfect quality chicken genome selection strategy and phenotypic accurate determination system, and cultivated 10 high-quality chicken strains with their own characteristics." Formed 3 new varieties of high-quality chicken matching lines, submitted 2 varieties for national review, developed 1 broiler breeding chip, the new technology has been applied to 240 million commercial broilers, and the annual output value has increased by hundreds of millions of yuan." Zhang Haihan told China Youth Daily, China Youth Network reporter said.
Ding Wenjia, brand manager of Huazhi Biotechnology Co., LTD., lamented to reporters that in the matter of "eating chicken", only "mastering key breeding technologies" can "genetic improvement of unique traits of existing varieties in China, so as to optimize and upgrade, and overtaking on corners".
Ding Wenjia told China Youth Daily, China Youth network reporter, the Chinese people used to demand chicken, to a large extent relied on the introduction of white feather chickens from abroad. These chickens are popular because of their fast growth rate and high feed conversion rate, but it also means that China has long relied on imports for provenance. This not only increases costs, but may also bring instability to the supply chain.
In order to get rid of this dilemma, the Beijing Institute of Animal Husbandry and Veterinary Medicine of the Chinese Academy of Agricultural Sciences has actively engaged in promoting the breeding of new varieties of white feather broilers. After years of unremitting efforts, finally in 2021 successfully cultivated a new breed of "Guangming No. 2" white feather broiler with independent intellectual property rights.
In order to promote the breeding and improvement of "Guangming No. 2" white feather broiler, Beijing Institute of Animal Husbandry and Veterinary Research of Chinese Academy of Agricultural Sciences and Huazhi Biological jointly established a white feather broiler research Center, which released the world's first intelligent blood analyzer for poultry disease resistance breeding in 2024, marking a breakthrough in the field of poultry disease resistance breeding intelligent equipment for phenotype identification. It provides an efficient, convenient and accurate intelligent data tool for poultry disease resistance breeding.
Through advanced technologies such as gene editing and molecular breeding, scientists can more accurately discover and breed good breeds to improve the growth performance and meat quality of broilers. The application of these technologies has not only accelerated the process of localization of broiler breeds, but also injected new vitality into the sustainable development of China's agriculture.
Good seeds, good planting and breeding methods can produce good results. "Good seed, good method", in the introduction, cultivation and optimization of plant and animal varieties, Wang Zhaohui, vice president of Huazhi Biology, summed up with these four words.
"We will also further increase research and development investment in the field of breeding, strengthen the construction of scientific and technological innovation platforms, train and introduce more high-quality professionals, and constantly improve the level of poultry breeding and innovation ability."
