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."
。 冀时新闻报道 易安社区是雄安新区启动区首个承接北京非首都功能疏解任务的示范社区，现有2000多户居民。
二 | 系列报道《自豪！我是雄安人》，今天带您认识社区党支部书记、居民的"好管家"——徐正。
三 | 雄安新区易安社区党支部书记 徐正：咱们只有走进每家每户，才能知道真正他们需要的是什么。每周一、二、四下午4点到晚上8点，是徐正和同事们入户走访的时间。在徐正看来，想要让疏解人员放下顾虑、以雄安为家，走访摸排、了解群众需求是做好服务的第一步。除了提前预约上门走访，他们还有一个更接地气的工作方法---"数灯敲门"。
四 | 晚上看到哪家窗户亮着灯，就上门敲一敲，唠唠家常、问问需求，确保走访不落一户。雄安新区易安社区党支部书记 徐正：看看咱们有没有什么需求、问题、意见和建议。居民：一直做的都挺好的，包括社区的活动也都挺多的……建设好雄安新区，要同步推进城市治理现代化，从一开始就下好"绣花"功夫。2024年7月易安社区整体交付入住后，徐正就和同事们一起，逐家逐户地走访，为每户居民建立民情台账，家庭结构、特殊需求、困难问题等一一记录在案，做到"一户一档"精准服务。
五 | 为实现诉求快速处置，徐正以楼栋为单位建起100多个便民服务微信群，公安、物业、燃气、电力等工作人员全都入群。居民的大事小事，只要发到群里，就能第一时间解决，社区居民诉求办结率超95%。
六 | 社区居民 邓粲：微信群把社区的居民和服务部门连接在了一起。我们可以直接就在群里面联系所需要解决问题的这些单位。解决好日常琐事只是基础，拉近邻里感情、消解异乡隔阂，才能让社区真正有家的氛围。两年来，徐正牵头组建了8个志愿服务队、33个文体社团，"益童成长"少儿活动、"青创未来"青年沙龙、"老友记"老年文娱等特色品牌活动深入人心。一场场邻里活动，让原本互不相识的异乡邻居逐渐熟悉起来，"陌邻"成了"睦邻"。社区居民 赵美香：这都是五湖四海的，这是从四面八方过来的，都是从不认识到认识，相识就是缘分。服务很好，做到我们心坎里，各个服务都很到位。社区配套不断完善、文体活动日益丰富，养老托管、儿童照看、通勤保障等一件件民生实事落地见效，精细化、有温度的服务，让疏解群众从"落地安居"走向"扎根乐业"。雄安新区易安社区党支部书记 徐正：看着老人有地儿去、孩子有人管、年轻人安心上班，这种变化，就是我和同事们每天奔波的答案。能在雄安这片热土上，为服务疏解、建设新城出一份力，我打心底里自豪。在雄安，像徐正这样扎根一线的基层工作者比比皆是。
七 | 他们或许岗位不同、分工各异，但心里都装着同一个目标：用心用情做好保障，让每一户疏解家庭留得住、融得进、扎下根。雄安新区文华社区工作人员 刘丽：我是2023年来到新区参与社区基层工作的。亲眼见证着疏解家庭在这里扎根、跟着新区一起变好，我打心底里觉得，这份工作特别有意义！雄安新区容西片区管委会 王一林：我们打造了"格物致知 书香容西"的全民阅读品牌、也打造了容西的儿童戏剧品牌，希望这些家庭不仅可以住上好房子，过上好日子，还能够享受更加丰富多彩的精神文化生活。雄安新区易安社区工作人员：我的主要工作，是在小区的日常巡查当中排查小区的安全隐患，保障小区的整体卫生整洁，让疏解居民在启动区过得安心、舒心。
