German test-day models, as the chief scientist I developed genetic evaluation systems for
German dairy cattle populations based on a random regression test-day model: 1999 to
2002 for milk production traits, 2002-2003 for somatic cell scores.
German QTL-MAS projects (ADR1 and ADR2), I made contributions to these projects.
