The No. 1 dairy breeding chip was successfully developed in Youran Animal Husbandry (09858) Secstar

The Zhitong Finance App learned that recently, Youran Animal Husbandry (09858) successfully developed a “high-yield, longevity, disease-resistant” genetic detection chip with independent intellectual property rights - “breeding No. 1 chip”, marking an important technological breakthrough in the efficient and accurate screening of “high-yield, longevity, and disease-resistant” dairy cows, and has completely independently mastered genomic testing technology for “high-yield, long-lived, and disease-resistant” dairy cows.

Currently, the average number of dairy cows produced by large-scale farms of domestic animal husbandry groups is less than 3. Most of them are eliminated due to poor production performance or health problems, which not only increases the cost of the ranch, but also limits the further improvement of ranch efficiency. In order to improve the efficiency of dairy farming in China, which can quickly identify and screen dairy cows with “high yield, longevity, and disease resistance” characteristics, Excellent Animal Husbandry Secstar has developed the “Breeding No. 1 Chip”. The chip uses CAGT targeted capture sequencing technology and high-throughput genetic testing technology to accurately and efficiently identify and breed dairy cows with higher production potential, longer production life, and stronger disease resistance, thereby speeding up the progress of improving the genetic quality of the entire herd, and also greatly improving the ranch's carbon emission reduction efforts.

Youran Animal Husbandry Saikexing has tested more than 300 cows using the “Breeding No. 1 Chip”, and the accuracy of “high yield, longevity, and disease resistance” genetic screening has reached the international advanced level. Youran Animal Husbandry Saikexing became the first domestic company to market the genetic testing technology for domestic “high-yield, long-lived, and disease-resistant” dairy cows.

The value of this genetic testing technology is that after calves are born, hair follicles, blood, or ear tissue can be collected, and the “breeding No. 1 chip” can be used to test and evaluate the cow's “high yield, longevity, and disease resistance” genetic traits. Combined with the “Comprehensive Breeding Index” of this calf, its breeding value can be accurately predicted, greatly improving the efficiency of high-quality population selection.

The achievement of the above technological achievements is due to the strong scale advantages, leading technical strength and deep talent reserves of Youran Animal Husbandry. Currently, Youran Animal Husbandry has 96 large-scale ranches across the country, raising more than 600,000 dairy cows, and has carried out DHI tests for nearly 260,000 dairy cows. Of these, nearly 160,000 cows have complete data records and meet breeding requirements, and the herd sample base is strong. Today, Youran Animal Husbandry has a technology research and development team of nearly 400 people, led by 23 doctorates, and 162 master's degrees. It has studied and mastered sex control technology, stem cell biological breeding technology, cow cloning technology, embryo production and transfer technology, and core gene editing technology, and has built a “Animal Germplasm Resources and Embryo Engineering Technology Academician Expert Workstation”, and undertakes the “National Dairy Industry Technology Innovation Center - Dairy Cow Breeding and Breeding Technology Research Sub-Center” and the “Ministry of Agriculture and Rural Affairs Key Laboratory for Cow Germplasm Creation and Breeding Technology”” Three major dairy cow breeding The platform has accumulated strong intellectual property assets for scientific and technological innovation and technological breakthroughs in Youran Animal Husbandry.

In the future, Youran Animal Husbandry will accelerate the technological transformation strategy, deeply cultivate dairy breeding technology, push the Chinese dairy industry forward with scientific and technological strength, and contribute more wisdom and solutions to the high-quality development of China's dairy industry.
