Providing Customized Breeding Plans Based on DNA
Expected to Resolve Semen Concentration Issues and Improve Production Efficiency
The Chungnam Provincial Livestock Technology Research Institute has become the first among local governments nationwide to successfully develop the 'CN-Hanwoo Genomic Information' application, which features a genomic-based Hanwoo cattle improvement system.
On July 4, the Livestock Technology Research Institute held an information session at the Gongju Agricultural Technology Center Exhibition Hall, attended by leading Hanwoo cattle breeders, regional livestock cooperatives, and the Korea Institute for Animal Products Quality Evaluation. During the session, the institute shared details about the app's development. The event included a demonstration of the application, collection of feedback from farmers, and a comprehensive discussion.
The newly developed app goes beyond traditional pedigree-based analysis, using DNA genomic information to control inbreeding and propose customized KPN breeding plans for each animal.
This is expected to enhance both the diversity of cow lineages and reproductive efficiency, while also strengthening the scientific foundation of Hanwoo cattle improvement.
In practice, genomic analysis provides a reliability rate of 70 to 80 percent, which is significantly higher than the 50 to 60 percent reliability of pedigree analysis. It also enables the estimation of genetic potential in calves.
Particularly noteworthy is the app's ability to alleviate the concentration of preferred semen on specific animals and to enable optimized KPN semen selection for each individual.
The app was jointly developed with 'Quandomic,' a youth startup company from Chungnam National University. Its main features include: ▲ Hanwoo pedigree information ▲ Genomic analysis data ▲ Inbreeding verification ▲ Customized breeding combination recommendations ▲ Carcass performance prediction and comparison with actual results.
The Livestock Technology Research Institute plans to collect basic genomic analysis data from farms by the end of this month and will gradually provide services by linking the analysis results to the app.
A representative from the institute stated, "The app, which allows users to easily check Hanwoo cattle information based on scientific analysis, will help improve the productivity and competitiveness of farms in the province. We will continue our efforts to maintain and manage the service so it can be expanded nationwide."
