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.

。    《日报》全媒体记者  赵丽杰          　　绥中县秋子沟乡谭杖子村北侧的尖山沟，是一片荒山，1000多亩。

二 | 多少年来，这片荒山一直处于荒芜状态，没有任何产出。

三 | 去年10月，3台挖掘机开上荒山，整天机声轰鸣，整整干了一个多月，杂草丛生的荒山变成了良田。

四 | 今年4月初开始，这片荒山上来了一群人，他们挖坑、扶正树苗、挥锹培土、踩土定植、提桶浇水，道道工序一丝不苟，场面更是热火朝天……原来，这是该乡四个村集体在栽种刺嫩芽。这件大好事的起因，还得从三年前两位村支部书记试验种植刺嫩芽说起。

五 |                    　　王存廷是秋子沟乡腰岭子村村支部书记，村子里的荒山没有产出，王存廷一直想让荒山充分发挥它的使用价值，和他有同样想法的还有谭杖子村村支部书记任忠平。王存廷和任忠平先后来到吉林梅河口和抚顺清原等地考察，经过多方联系取经，2021年春季，两人自掏腰包从吉林省梅河口购进刺嫩芽小苗，分别开出20亩和10亩荒山种上小苗。去年，刺嫩芽产生了收益，纯绿色的刺嫩芽以每斤40元的价格销往北京和本溪、抚顺等地，初步估算，每亩地收益3000元左右。一分钱不出的荒山有了产出；另外，整个种植过程中，还雇用村民务工，每天工资100多元，促进了村民在家门口就业；村民出租荒山还能收到租金，一举多赢，让大家看到了美好前景。

六 |                    　　王存廷和任忠平试种刺嫩芽收到一定成效，秋子沟乡党委书记朱洪军看在眼里，喜在心上。在一次碰头会上，他与西山村、八家子村、谭杖子村、腰岭子村4名村支部书记不谋而合：咱们要因地制宜，发展刺嫩芽这一特色产业，来打造农业产业新亮点，以壮大村级集体经济。                   　　说干就干！此前，腰岭子村已成立“绿乡缘”种植合作社，几个村把上年结余的村集体资金注入“绿乡缘”种植合作社，从谭杖子村村民手中流转100亩荒山，这便出现了本文开头的一幕。从4月1日起，到4月15日，尖山沟每天都会有这热火朝天的劳动场景。4月17日采访时，任忠平告诉记者：“刺嫩芽成活率特别高，基本上是百分之百，现在都冒出小芽了，我们时常上山察看，冒出嫩芽的小苗充满生机，特别惹人喜爱。”                    　　“眼下，我们正协调荒山，准备扩大种植规模，并带动村民参与其中，探索‘党建引领+合作社+农户’模式，盘活整合各村闲置资源，以规模效益提升推动经济效益提升，发展特色产业，让荒山变成村民绿色家底，壮大村集体经济。”朱洪军坚定地说。
