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.

。北京时间1月8日晚间新闻，据外媒报道，亚马逊Go无人零售店不仅要在“便利”方面超越传统零售店，而且要在“收入”方面超越传统零售店。亚马逊Go预计在未来三年的业务额将超过40亿美元。加拿大皇家银行资本市场（RBC Capital Markets）的分析师预计，亚马逊将比传统便利店多创造约50%的收入。分析师估计，亚马逊Go的常规订单金额约为10美元，平均每天有550名客户，平均年收入约为150万美元，不包括非营业时间。去年9月，据报道，亚马逊计划在三年内开放多达3000个亚马逊Go单元。如果亚马逊能够按时实施开发计划，那么到2021年，亚马逊Go的年销售额将达到45亿美元左右。2016年，亚马逊在西雅图推出了第一款亚马逊Go，最初只对亚马逊员工开放。如今，亚马逊在芝加哥、旧金山和西雅图等城市开设了七个亚马逊无人驾驶便利店。
