- Conduct research to discover, test, and implement improved genetic
evaluation techniques for economically important traits of dairy cattle
and goats
- Genetically improve efficiency of dairy animals for yield and fitness

- Improved evaluations for male and female fertility
- Improved evaluations of calving traits by accounting for genetic
differences by parity
- DNA information used in evaluations

|
- Joint project with Bovine Functional Genomics Laboratory
- Over 38,000 SNP informative for Holsteins
- Over 6000 bull and cows genotyped so far
- SNP effects estimated from animals with evaluations
- Evaluations of young animals
- Increased accuracy over parent information

|
- Field test results distributed for 750 nominated animals
- Extension to Jersey and Brown Swiss in progress
- Transition to commercial genotyping labs
- Extension to cows planned for June

|
- Genomic evaluations received on bull calves before purchase
- Genotyping required for bull dams
- Decreased number of bulls in waiting
- Marketing based on genomic evaluations
- Increased rate of genetic improvement

|
- Genetic evaluations developed by AIPL are basis of impressive rate of
genetic improvement
- Frequent innovations improve accuracy and add traits of economic
importance
- Genomic information expected to lead to large changes in animal breeding
industry
