Core Viewpoint - The article highlights the transformation of the sheep breeding industry in China, led by Li Junlong, who established the world's largest sheep embryo factory and significantly improved the economic conditions for local herders while promoting ecological sustainability [1][5]. Group 1: Industry Development - The sheep breeding industry in China faced challenges such as low efficiency and ecological degradation, prompting Li Junlong to innovate through "meat sheep breeding" technology [1][2]. - The establishment of the Sino company in 1997 marked a pivotal moment in the industry, focusing on advanced breeding techniques and overcoming initial financial struggles [1][4]. - The introduction of the new "Dumeng sheep" breed, developed through 600 trials over 18 years, exemplifies the commitment to improving breeding quality and efficiency [4][5]. Group 2: Technological Advancements - The company has successfully expanded the breeding of over half of China's imported quality sheep, achieving international standards and breaking the cycle of breed degradation [5]. - The annual production capacity of 300,000 embryos at the Sino company has positioned China as a leader in sheep breeding, with 88% of the global embryo production in 2023 attributed to China [5][6]. - The company has contributed significantly to the body of research in sheep breeding, with many international papers now citing their data [5]. Group 3: Economic Impact on Local Communities - The implementation of the "breeding joint venture" model has led to increased income for local herders, with the new Dumeng sheep allowing herders to earn an additional 150 yuan per sheep compared to local breeds [7]. - The ecological and economic model has been adopted by over 500 households, producing over 100,000 hybrid lambs annually and increasing income for each mother sheep by over 500 yuan [7]. - Li Junlong aims to further promote biological breeding across the country, enhancing the competitiveness of China's sheep industry on a global scale [7].
