The article explores the potential of introducing low-lying species in the South Korean dairy industry to enhance competitiveness, reduce manure, and improve environmental issues. These species, which are small, efficient, and have a high non-solid content in their crude oil, could help reduce feed costs, improve profits, and promote national health. Additionally, they could help decrease greenhouse gas emissions by reducing manure and providing better quality milk for cheese-making. Gyeonggi-do has supported this initiative with an ordinance, and plans are underway to replace 10% of the cows in the region with these species, which are easy to adapt to domestic conditions and can be reared with Holsteins. However, challenges such as high cost of fertilized eggs and potential impact on the beef cattle industry need to be addressed.
