N China's Inner Mongolia launches homegrown ‘Breeding No.2’ gene chip for quality dairy cattle breeding_我的网站

一 |     (ECNS) -- More than 2,000 humanoid robots from 16 countries will compete at the second World Humanoid Robot Games in Beijing from Aug. 22 to 26, a sports official said Thursday.     A total of 666 teams and 2,056 robots have registered, said Yu Qingfeng, director of the Beijing Sports Bureau and executive deputy director of the Games’ organizing committee.        The Games will feature 1,301 contests across 51 events at the National Speed Skating Oval, also known as the “Ice Ribbon.”    Highlights include robot soccer, with participants now able to dribble while running, take powerful shots and dive to make saves.    Robots will also compete in combat, weightlifting and dance, while other events will test practical skills such as emergency response, hotel services and fine movements like picking up beans and tightening screws.    Dance events have attracted 108 teams, up from 29 last year, with robots set to compete in street dance, ballroom dance and cheerleading.             Competition standards have been tightened, with the 100-meter race time limit cut from three minutes to one, and most events required to be completed autonomously.     (By Helen Mo, intern Yang Hongran)                    。

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.
