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."
。这场俄乌冲突的阴影，越来越漫长，也越来越浓重。英国选择持续向乌克兰提供攻击型无人机，如同在平静的水面上投下了一颗巨石，激起了俄罗斯的强烈反弹。俄罗斯驻伦敦大使馆的警告，掷地有声，带着一种近乎绝望的愤怒。口头上谈论和平，暗地里却助长战火，俄罗斯指责英国的行为，像一把锋利的匕首，直指伦敦的心脏。这不仅仅是一场外交上的争执，更像是俄英关系进入了一个新阶段的信号——一场潜伏已久的、无声的较量，即将全面升级。这一次，俄罗斯似乎已经放弃了传统意义上的大规模正面开战。战场，不再仅仅是乌克兰的土地，而是悄无声息地蔓延到网络、本土、以及那些隐藏在暗处的灰色地带。网络袭扰，本土破坏，间谍暗杀……这些低成本、高风险的手段，正成为俄罗斯报复英国的主要方向。

二 | 俄罗斯对英国的网络攻击，由来已久，如同挥之不去的阴影。

三 | 勒索软件，金融诈骗，这些牟利性质的网络犯罪，只是冰山一角。更令人担忧的是，针对政府机构和民生基础设施的间谍与破坏性袭击，正如同潜伏在暗处的毒蛇，伺机而动。仅仅过去六个月，英国就遭遇了惊人的数据泄露，超过两千台设备被俄罗斯常用的Lumma窃取程序入侵，敏感信息如同被盗窃的珍宝，落入敌手。想象一下，俄罗斯的情报机构，如同一个精密的机器，源源不断地挖掘着英国系统的漏洞。一旦局势进一步恶化，那些潜藏在工业控制系统中的零日漏洞，说不定就会被用来瘫痪供水、能源、通信等，关系到民生运转的关键设施。人们不禁要问，英国的核心基础设施难道真的如此不堪一击？专家认为，英国在这方面的防护相对完善，但俄罗斯的攻击重心，很可能转向那些防御薄弱的民用目标。例如，近年来，英国本土已经出现了破坏活动。多名受俄罗斯指使的人员，因为策划纵火袭击而被绳之以法，目标包括政客的私人房产，以及为乌克兰转运物资的仓库。单单是伦敦一处援乌仓库的袭击，就造成了130万英镑的损失。未来，汽油弹袭击，针对援乌物资仓库的纵火，甚至利用无人机闯入希思罗、盖特威克等大型民用机场上空，扰乱全球民航运行，都将成为俄罗斯可以轻易动用的手段。德国近期机场遭无人机滋扰的事件，已经如同一个警钟，敲响在整个欧洲的上空。而暗杀与间谍活动，则如同棋盘上的无形力量，随时可能改变局势的走向。俄罗斯的过去，早已在英国留下了深深的伤痕。利特维年科的放射性中毒，斯克里帕尔父女的神经毒剂遇袭，这些事件如同噩梦般挥之不去，时刻警示着英国的情报部门。而现在，这些间谍活动依旧在持续，英国情报机构不断挫败着俄方的秘密部署。

四 | 暗杀的前期筹备，与间谍作业常常是高度重合的，锁定目标，摸清行动轨迹，寻找漏洞，整个流程随时可以落地。当然，俄罗斯要直接对英国军工企业高管、政坛高层下手，那几乎是不可能的，这些人的安保等级极高。

五 | 俄罗斯过往的暗杀对象，更多地是本国叛逃人员，以及欧洲境内的乌克兰人士——他们，无疑是风险更高的目标。除了在英国本土制造麻烦，打击乌克兰境内的英国相关设施，也同样是俄罗斯的报复路径。英国在乌克兰境内设立了多处装备维修基地，大量装甲车、火炮在此进行检修，BAE系统公司也在乌设立分支机构。如果俄罗斯能够掌握精准的情报，导弹或无人机就可以轻易摧毁这些基地，甚至杀伤现场的英国工作人员。然而，俄罗斯至今没有对已知的英国海外仓库发动打击，这表明其情报搜集方面可能存在短板，同时战争消耗也让俄罗斯可调配的额外作战资源变得紧张。尽管俄罗斯拥有远程自杀式无人机，并新建了大量的发射阵地，但主流军事专家普遍认为，直接对英国本土发动公开的军事打击，可能性极低。一旦对北约成员国实施明目张胆的军事进攻，将会触发北约集体防御条款，招致整个西方集团的联合反击，这对目前深陷乌克兰战场的俄罗斯而言，无疑是雪上加霜。
