Core Insights - The Chinese dairy industry has made significant advancements in milk production, with some high-yield farms achieving an annual milk yield of 14 tons per cow by 2024, surpassing most developed countries [1] - The overall quality of Chinese raw milk has improved, with key indicators such as protein, fat, and bacterial counts exceeding EU standards, indicating a world-class quality [1] - The rapid development of the dairy sector in China, completing in 20 years what took developed countries over a century, is driven by domestic innovations in breeding and technology [1] Group 1: Genetic Improvement and Technology - The increase in dairy production and quality is fundamentally linked to the genetic improvement of dairy cattle, facilitated by whole-genome testing technology [2] - Whole-genome testing provides precise breeding values, accelerates genetic progress, and reduces the risks of inbreeding, but its high cost and time consumption hinder widespread adoption in China [2] - A team led by Li Xihe has developed domestically produced gene chips that significantly reduce testing costs and improve efficiency, achieving a fourfold increase in efficiency and a cost reduction to one-fifth of whole-genome sequencing [2][3] Group 2: Breeding and Data Utilization - The breeding capability of dairy cows is heavily influenced by the genetics of their parents, with top bulls contributing over 75% to genetic improvement [4] - The establishment of a breeding big data platform across 96 large-scale farms has enabled the collection of comprehensive data on each cow, facilitating the identification of superior breeding stock [5] - The use of machine learning algorithms has allowed for the rapid identification of genetic markers associated with desirable traits, reducing the breeding cycle from six years to two [5][6] Group 3: Smart Farming and AI Integration - Traditional dairy farming faces challenges such as high reliance on manual labor and fragmented data, which can be addressed through smart farming technologies [7] - The "YILI-AI" system developed by Yili integrates AI technology to enhance dairy farming efficiency, providing precise solutions based on extensive historical data [8] - The implementation of AI has led to an increase in daily milk production by 1.66 kg per cow and a reduction in management costs by 0.31 yuan per kg of milk [8]

一头奶牛能发掘出多少意想不到的产奶潜能？ 针对这一痛点，李喜和带领团队开发出具有自主知识产权的系列基因芯片——"高产、抗病、长生产期"奶牛特殊性状基因检测芯片与奶牛 胚胎基因组遗传评估芯片。采用该系列基因芯片进行基因检测，效率比全基因组测序提升4倍以上，成本仅为其1/5。 李喜和介绍，基因芯片类似流行病毒快检试剂盒，只要把奶牛的样本组织涂抹到试剂盒上，就会与芯片上记录的奶牛繁殖、健康、生产寿 命、饲料转化率、乳蛋白量、乳脂量、体细胞数等性状信息发生反应并呈现出不同颜色，快速出具能否高产、优产的诊断。 中国牛用上"中国芯"，中国奶牛育种技术和繁育形成了"芯片检测-智能选配-精准繁育"闭环，国外良种奶牛种源与繁育关键技术"卡脖 子"问题相继被突破。 2000年，中国奶牛年单产仅为2605公斤/头，3头奶牛产奶量才相当于奶业发达国家1头牛的产奶量，整体水平与奶业发达国家有上百年差 距；2024年，中国部分高产牧场奶牛年单产达14吨/头，已超越绝大多数奶业发达国家。原奶的蛋白质、脂肪、体细胞数、菌落总数等核心指 标的总体水平优于欧盟标准，中国牛奶已经是世界级品质。伊利原奶的菌落总数更是远优于欧盟标准，实现了划时代的进 ...
