China’s top pork-producing province rolls out homegrown 'gene chip' for breeding quality pigs_我的网站

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."

B | 昨天在Coronation Rd一座教堂附近发生了大火，这是最近三周Māngere地区发生的一系列火灾中的最新一起。 Advertise with us 上周一，消防和紧急服务部门接到报警，称位于Māngere East的Massey Rd上的一栋公寓楼发生火灾。 一周前，消防人员还接到过报警，并前往了附近的Vine St的一处大型房屋火灾现场。在此两个多小时前，他们曾接到呼叫，附近Onehunga地区Church St的一处房屋着了火。 在那场大火中，一人受了轻伤，被送往医院。
C | 11月12日周日晚上，消防队员忙于扑灭Favona地区Walmsley Rd上一栋联排别墅的大火。据报告，几天前在Māngere山顶也发生了火灾。 据悉，昨天凌晨的大火导致10户家庭无家可归，着火的房屋没有安装火灾警报器。
D | 火灾警报器能拯救生命 Māngere-Ōtāhuhu地方委员会主席Tauanu’u Nick Bakulich说，这是一个及时的提醒，提醒家庭检查家中是否有烟雾警报器，尤其是在圣诞节即将到来的时候。 “这是一件悲惨的事情，尤其是在节日来临之际。这些人将面临挑战和心痛。” “感谢上帝，没有人员伤亡。
E | 我们正在想着那些失去家园和财产的家庭。” “这是一个关键信息——安装火灾警报器。你检查过它们是否工作吗？有电池吗？” Tauanu 'u说，他和其他一些当地社区的成员昨天去了被疏散的家庭所在的教堂。 这座名为Siasi Tokaikolo ' ia Kalaisi ' Api ko Nasaleti的教堂在当地汤加社区非常有名，在Māngere也很出名。 太平洋健康和社会服务提供商The Fono和由前拳击手转变为社区倡导者的Dave Letele的Brown Buttabean Motivation（BBM）组织为受影响的家庭带来了食品包、衣服和其他用品。 社区机构立即作出反应 听说了他们困境的普通民众也带着衣服、食物和床上用品来到教堂捐赠，一些人还来捐了现金。 Tauanu 'u说：“社区立即做出了反应和回应。
F | ” Kennedy Fakana 'ana ' -ki- fualu因帮助社区中有需要的人而被称为“汤加罗宾汉”，他也在被困的人当中。
G | 他感谢Letele和BBM团队在接到简短的电话后迅速反应，提供了食物和物资。 “他们马上给了我们装有冻肉、面包和这10个家庭所需的一切的食品包。” “这证明像BBM这样的社区组织总是在那里，而且速度很快。我们也不能坐等救援。” 警方表示，他们将继续调查这场火灾的情况，但证实他们并未将其视为可疑事件。
