North China's Inner Mongolia Autonomous Region has launched a genomic breeding tool for dairy cattle, also known as a gene chip, enabling precise screening for key traits such as high milk yield, high fertility, disease resistance and longevity, and marking a fresh breakthrough in China's dairy cattle breeding technology, the Inner Mongolia Daily reported on Saturday.
As an iteration of the previous generation dairy cattle breeding array, which holds proprietary intellectual property rights, the new-generation "Breeding No.2" breeding array was led by the National Center of Technology Innovation for Dairy and developed by Youran Dairy Saikexing, with upgrades in loci coverage, compatibility and gene-trait prediction algorithms. 
The "Breeding No.2" breeding array covers about 50,000 loci across the dairy cattle genome, with a focus on functional loci tied to milk production, reproduction, disease resistance and length of productive life. It has achieved a sample call rate of 99.65 percent and a genotyping concordance rate of 99.91 percent for duplicate samples, and is compatible with mainstream international chips, allowing historical breeding data to be shared and reused. 
Drawing on a phenotype database and genome resequencing data to optimize a proprietary algorithm, advancing breeding evaluation from qualitative screening to quantitative assessment, bringing the accuracy of breeding stock selection up to advanced international levels, according to the report. 
The breeding array enables more precise genomic selection of calves at an early stage, substantially shortening the generation interval in breeding bull selection and cutting spending on raising low-performing replacement heifers. Compared with imported high-density chips, the "Breeding No.2" chip carries a lower per-sample testing cost and delivers stronger input-output returns, making it highly suited to large-scale dairy cattle breeding operations in China, the report said.

4月21日，足球报发文透露，有陕西高层直言，将会全力完成在中甲的保级任务。

中甲战罢4轮，陕西联合1胜1平2负积4分排在第11位，虽然说处于联赛中下游，但西北狼对于完成保级目标还是充满自信。俱乐部高层就直言：“从前4轮来看，队员们还是保持着高昂的斗志，大家都很团结，联赛才刚刚开始，我们只是打了一个主场，有渭南赛区、诸多赞助商的大力支持，还有这么好的球迷，我们一定会全力以赴完成保级任务！”

该媒体表示：陕西联合的自信是有根基的，除了球迷、赛区支持以及球队内部团结稳定外，还有就是俱乐部新赛季整体运营情况良好，阿克苏月亮泊景区成为2025赛季球队冠名合作伙伴，能获得冠名实属不易，这也反映出西北狼的号召力和俱乐部营销策略的成功。不仅仅是冠名，在市场环境不佳的大背景下，俱乐部还主动作为，合作方涵盖各行各业，真正做到了众人拾柴火焰高，联合一切可以联合的力量，都来助力陕西职业足球奋勇前行。

在主场球票发售上，市场反响很好，陕西联合新赛季主场即便仍然放到渭南，但每到周末，省内各地开车、乘坐高铁到渭南看球的球迷仍然是络绎不绝，甚至还出现一票难求的盛况。球迷热情解囊，一定程度上也缓解了俱乐部的经营压力。
