Recently, the National Center for Genetic Evaluation of Livestock and Poultry released the 2025 third genetic evaluation results for Chinese dairy breeding bulls, aiming to recommend superior bulls and guide farms in scientifically selecting high-quality frozen bovine semen. This evaluation utilized China's independently developed China Performance Index (CPI) and Genomic China Performance Index (GCPI), announcing the genetic assessment scores for 1,222 Chinese Holstein breeding bulls from 18 national bull stations, which included conventional genetic evaluation CPI scores for 224 bulls and genomic genetic evaluation GCPI scores for 998 young bulls.
Breeders and producers can access and utilize this information by logging into the China Big Data Platform for Seed Industry (http://202.127.42.145/bigdataNew/) or the official website of the National Animal Husbandry Technical Extension Center (http://www.nahs.org.cn). Since the implementation of the seed industry revitalization initiative, the Ministry of Agriculture and Rural Affairs has organized the in-depth execution of a new round of the National Dairy Cattle Genetic Improvement Program, carrying out bull registration, performance testing, and genetic evaluation, while refining performance indices suitable for China's dairy cattle breeding.
These indices comprehensively assess bull performance and genetic selection progress across three major trait categories: milk production performance, conformation, and health, and involve the timely release of information on superior bulls to promote genetic exchange and continuously enhance the quality of frozen semen and breeding standards. In the next phase, the Ministry of Agriculture and Rural Affairs will further optimize the China Performance Index and the Genomic China Performance Index by incorporating additional traits such as fertility, calving ease, and productive lifespan, enabling a more comprehensive evaluation of dairy cattle breeding value.
The Ministry also plans to increase the frequency of national genetic evaluations for breeding bulls, promptly publish the results, and organize technical extension departments at all levels to strengthen training and guidance for bull stations and farms. This effort aims to guide farms in scientifically selecting and mating bulls, thereby promoting cost reduction and efficiency gains in the dairy industry and improving overall profitability.
