China's largest pork-producing province has introduced a genomic breeding tool designed for indigenous pig breeding, a sign that the province is shifting from expanding volume toward improving hog quality.
The Henan Academy of Agricultural Sciences announced the launch of Yuzhu-1 Henan indigenous pig 15k breeding array - commonly known as a gene chip - developed by the pig breeding team at its Institute of Animal Husbandry and Veterinary Science. It is the first such tool customized for the province's native pig stock, the institute said on Monday.
Henan is home to multiple native pig breeds prized by consumers for their good flavor. However, they carry a commercial burden compared with imported lean-meat breeds, as they grow more slowly, consume more feed per kilogram of weight gain and deliver thinner margins, noted Xing Baosong, head of the pig research office at the institute.
Lifting those hurdles depends on sharper selection, which in local herds has long relied on visual assessment of physical traits, which is slow and imprecise. Genomic tools can speed things up, but mainstream commercial chips were built on imported breeds and lose accuracy on native Chinese stock. Yuzhu No 1 instead draws on whole-genome resequencing data from five of Henan's native pig breeds and two locally bred lines.
"In breeding we rely on estimated breeding values to judge an animal's genetic potential," Wang Ligang, a professor at the Institute of Animal Sciences under the Chinese Academy of Agricultural Sciences, told the Global Times on Monday. "An array matched to the breed makes that estimate more accurate. Previously there was a real chance we were selecting the wrong animals. Now we are far more likely to be selecting the right ones - and to select accurately for the traits a breed is known for, whether that is tender meat or high fertility."
The efficiency gap between native and imported pig breeds remains wide, said Wang, who is also with the Pig Branch of the Chinese Association of Animal Science and Veterinary Medicine. Feed conversion ratios for local Chinese pigs run around 3.0, against below 2.5 for imported breeds, while reaching 100 kilograms takes native pigs 180 to 190 days compared with 130 to 140 days for exotic lines, he said. 
Despite this, China's native pig breeds have their advantages.
"Our pigs taste better, partly because they are raised longer," Wang said. "And they are far more robust. Exotic breeds can suffer heat stress and die in summer; when disease hits, they can go down in large numbers. Local pigs rarely do. They tend to recover. Some breeds in Northeast China can even tolerate severe cold."
He added that imported breeds drive efficiency, while native breeds ensure quality and offer a reservoir of genetic diversity for disease and stress resistance - traits that can be bred back into commercial lines.
The province slaughtered 64.74 million pigs in 2025, up 7.4 percent year on year, with pork output at 5.22 million tons, according to the provincial statistics bureau, making it the top pork and pig producer nationwide, according to industry statistics. 
In the first half of 2026, pig slaughter in the province rose a further 6.4 percent, accelerating 5.3 percentage points from the first quarter, against national growth of 1.7 percent. Xing said that more high-quality local black pigs will reach the market as Yuzhu No 1 is applied more broadly. 
Other major pig production provinces such as Southwest China's Sichuan, Northwest China's Shaanxi and South China's Yunnan have all developed their own arrays.
"Provinces with the most developed pig production are the ones pushing upmarket," Wang said. "Scale is no longer the only measure. If every province reaches this level, a pattern of one dedicated array per province could gradually take shape for China's native breeds."

(Xinhua/Fang Zhe)The Shanghai Science and Technology Museum welcomed its 100 millionth visitor on Tuesday, as a growing number of travelers are looking to make science and technology a part of their holidays.
Zhang Zhiheng, a boy from east China's Shandong Province, was the landmark visitor. He visited the museum with his parents on the second day of his first trip to Shanghai.
Since opening its doors to the public in late 2001, the museum has grown into one of China's most popular science and education destinations. Through a wide range of science and technology activities and programs, it remains dedicated to boosting public scientific literacy and sparking curiosity in visitors of all ages.
After being closed for over two years for upgrading, the museum reopened early this year. It now also includes two branches: the Shanghai Natural History Museum and the Shanghai Astronomy Museum.
Back in 2001, the proportion of Chinese citizens with scientific literacy was only 1.4 percent, and the figure had risen to 16.74 percent by 2025, according to official data.
As public interest in science has grown, visits to science and technology museums have increasingly become part of everyday life.
For many families, museums have become a popular destination during holidays and weekends, offering children opportunities to expand their knowledge and broaden their horizons.
"The biggest change I feel during my museum visits is that science and technology keep advancing," said Zheng Qina, a post‑90s visitor from Shanghai. She was nine years old when she visited the museum in 2001. Today, her five‑year‑old son is also a regular visitor.
The trend is also extending to international travelers. With China's inbound tourism gaining momentum following eased visa policies, science museums have emerged as an increasingly popular destination for overseas visitors seeking a closer look at the country's technological development.
From January to July this year, the Shanghai Science and Technology Museum and its two branches received nearly 200,000 foreign visitors, accounting for nearly 5 percent of the total visitor numbers.
Francisco and his parents, a family from Italy, were among the visitors on Tuesday. After touring an exhibition on green energy, Francisco said he was deeply impressed by displays showcasing China's nuclear and hydrogen energy technologies.
In recent years, China has made major advances in fields ranging from artificial intelligence and humanoid robots to quantum science, green energy, space technology, life sciences and physical sciences. Science and technology museums offer visitors an opportunity to explore some of these developments through exhibitions and interactive experiences.
For Ni Minjing, director of the Shanghai Science and Technology Museum, a notable change among visitors is that they have shifted from passive recipients of knowledge to more active explorers of science.
"Teenagers in particular now have abundant channels to acquire knowledge. The role of science and technology museums can no longer be merely about resolving doubts," Ni said. "Instead, through diverse forms of science popularization, museums should inspire visitors, especially young people, to think and create."
"We will continue to innovate the way we popularize science, enrich science-related content, promote the spirit of scientists and foster a culture of innovation, so as to spark young people's curiosity, imagination and desire to explore," Ni added.
