Interbull
Multiple-trait Across-Country Evaluation (MACE)
Two-step procedure– National breeding values calculated by
each country– International breeding values calculated by
Interbull
Interbull Evaluation Process
Check of incoming data Build a global pedigree file Build a cross-reference file
Routine run, 3 times/year Test run, 2 times/year
Multiple-trait Across Country Evaluation (MACE)
Multiple-trait sire modelMultiple-trait sire model:
yi = countryi + sirei + errori
Each country considered as different trait
Deregressed national genetic evaluation results as input
