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."
。    南街逛吃、北街嗨玩杭州日报讯 南街逛吃、北街嗨玩！今年夏天，西湖区转塘街道BAC艺术社区（南街）联动塘人街市（北街）共同推出塘街夜市，将两处夜市串联成一条消暑夜游线。走进塘街夜市，音乐声、碰杯声、欢笑声交织成趣，各色美食摊位沿街铺开，烟火气与夜生活交织升腾。与去年的BAC艺术社区“单点作战”不同，今年转塘南北两大夜市区块首次实现联通，BAC艺术社区现场设置12个特色摊位，与塘人街市本身档口形成联动，从“各自为营”升级为“南北呼应”，让市民游客 “一杯一筷，吃遍南街北市”。

二 | “夜市开摆后，夜间客流每天增加500余人次，南北联动也激发了更大的消费活力。”夜市相关负责人介绍，夜市涵盖生腌、卤味、热炒、酒水等品类，共吸引50余个摊主报名参与。

三 | 这场夜市在每周五、六、日及节假日17:30至22:00开启，将从炎炎夏日延续至九月中旬。这种南北联动的模式，让转塘居民的“夜生活半径”悄然扩大。过去只能在BAC艺术社区里“逛一圈”的年轻人，如今可以沿着夜市路线一路逛到塘人街市，体验从南到北、从美食到潮玩的全链条夜消费场景。“以前在转塘晚上不知道去哪里，现在下班后约朋友来喝一杯、吃个串，再溜达到塘人街市逛逛，一个晚上的安排都齐了。”在附近工作的“00后”姑娘小郑说。从上城区专程过来拍照的刘女士也感受到了这份松弛。

四 | “之前来这里主要是逛店铺、拍照片，今天发现有夜市摊位，第一次留下来吃饭。”她向记者展示，“买了薄荷炸排骨，味道很不错。”夜市的人气也让摊主们对转塘的消费潜力有了新的判断。

五 | 摊主方糖卫永在杭州已有三家门店，这次摆摊主打“土菜洋酒”主题，将自有品牌的酒与杭州本土老字号“江南第一糟”里的糟味相结合。“BAC艺术社区的客群具备年轻化、爱玩敢试的特质，正是我们的目标客群。”方糖卫永表示，自己去过不少市集，转塘的夜市整体更轻松，让他愿意再来这里持续出摊。据悉，BAC艺术社区与塘人街市未来将继续联动，推动优质摊主从“临时出摊”走向“常态经营”。除了美食与美酒外，夜市现场还配套了丰富的娱乐活动。“夏夜噪点” 中， DJ现场演绎、即兴喜剧和吉他弹唱轮番登场，点燃夏夜热情；每周日19:00的“夏日放映”准时开启露天电影，为夜游增添一份浪漫；每周六20:00的“整点瓜吃”更是让“吃瓜群众”集结南北，准时“杀”瓜，将气氛推向高潮。美食、音乐、电影、互动……多重体验交织，让转塘的夜晚不止于“吃喝”。今年以来，转塘街道基于艺术氛围浓、烟火气息旺的区域特点，通过鼓励规范化夜市外摆、引进特色夜市品牌等方式，推动新消费转型升级。从塘街夜市到何家村“何你见未来”市集，转塘正以多点联动的夜经济格局，把“流量”转化为“留量”，让夜晚的松弛感与艺术范在街巷间持续流动。
