小鱼儿与花无缺美方称敦促中国配合针对伊朗的经济制裁 中方回应_我的网站
A |  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. Global Times 。 中新网北京8月21日电 (记者 张蔚然)中国外交部发言人林剑21日主持例行记者会。 据报道，美国财政部长贝森特称，美国将对伊朗实施“史上最严厉的制裁”，并敦促中国及美国盟友配合美方制裁措施。当日有记者就此提问。 林剑：我愿重申，中方反对没有国际法依据、未经联合国安理会授权的非法单边制裁，呼吁相关各方采取负责任举措，通过政治外交途径解决问题。(完) 【编辑:付子豪】。 Current article:http://www.lichuorenrenyitankanmeimu.cfd/news/20260826_121732.xls Published on:17:53:01 |
