Genomic breeding values for crossbred dairy cows
Joint Nordic genomic breeding values for dairyxdairy crossbred females were published for the first time in December 2021. NAV calculates genomic breeding values for genomic tested crossbred females having RDC, Holstein and Jersey genes. Requirements for crossbreds to be included:
- The sire of the crossbred animals must be HOL, JER or RDC
- The maternal grandsire of the crossbred animals must be HOL, JER or RDC
Genomic breeding values are calculated for NTM, and all overall indices in NTM except youngstock survival. Furthermore, GEBVs are calculated for milk, fat, protein and all conformation traits.
