Collaboration improves Jersey genomic selection

A new agreement to exchange Jersey genotypes has increased the North American Jersey genotype database on proven bulls by more than 1,100, and increased the reliability of genomic predictions, according to the American Jersey Cattle Association (AJCA).

The new agreement with Scandinavian-based Viking Genetics is the culmination of several years of collaboration between AJCA, the Cooperative Dairy DNA Repository (CDDR) represented by National Association of Animal Breeders (NAAB), and Canadian Dairy Network (CDN). The agreement establishes an ongoing exchange of genotypes for progeny-proven bulls in North America and Scandinavia, enhancing selection programs aimed at maximizing genetic potential while maintaining genetic diversity.

The formation of the CDDR by six U.S. and one Canadian A.I. center almost 20 years ago provided the sire DNA which enabled research by USDA’s Agriculture Research Service, the University of Guelph and CDN, resulting in genomic predictions now being utilized by dairy producers in both countries.
