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.

。女武神連戰連勝，反觀天空遭遇連敗打擊，此消彼長之下，女武神是役主場稱雄不在話下。

    　　女武神今季表現強勢，目前以23勝9負的戰績高居聯盟第二位，勝率高達71.9%。女武神今季擅長主場作戰，主場取得13勝4負的佳績是聯盟主場勝率最高的球隊。近況方面，女武神處於四連勝的強勢中，上仗與火花交手，球隊打出團隊籃球，10名出場球員全部有得分，其中贊達拿絲妮和嘉比威廉絲等4人得分上雙，此番面對遭遇連敗打擊的天空，相信女武神可以輕鬆延續勝績。陣容方面，K.史杜克斯遭遇腦震盪避戰。

    　　天空今季表現不佳，目前錄得12勝21負，不足四成的勝率排在聯盟倒數。

四 | 近況方面，上仗與排名聯盟墊底的暴風交手，雖然卡美娜卡度素和迪莊娜卡寧頓有不錯的發揮，但球隊防守不穩，最終88比97輸球，至此，天空遭遇兩連敗打擊，而且這是她們過去4場的第3場敗仗，士氣相當低落。另外，天空今季客場戰鬥力不足，只錄得4勝12負的劣績，此番出征，她們敗局已定。

五 | 人手方面，迪堅斯和悉妮泰萊傷缺。
