Distribution and Types of U.S. Evaluation
U.S. dairy genetic evaluations are released weekly, monthly and triannually – dependent on animal status. The triannual evaluations are in April, August and December.
Evaluation Types & Frequency
CDCB releases three types of genetic evaluations, generally on Tuesdays.
Triannual Evaluation
- Official evaluations in April, August, and December for all animals
- Genomic and traditional progeny evaluations are updated as new phenotypic data is included
- Top Animal Rankings and Summary Statistics updated
Monthly Genomic Evaluation
- Official genomic evaluations for all qualifying genotyped animals
- No updates in the phenotypic records are applied
Weekly Genomic Evaluation
- Preliminary evaluations not used for marketing animals or semen
- Used for quick decisions for mating, culling and herd management
