1 20012003 Interbull Technical Workshop, March 2-3 (1) Rex L. Powell and Paul M. VanRaden Animal Improvement Programs Laboratory Agricultural Research Service, USDA, Beltsville, MD rpowell@aipl.arsusda.gov Correlation of Longevity Evaluation With Other Trait Evaluations From 14 Countries

2 2001 R. L. Powell and P. M. VanRaden 2003 Interbull Technical Workshop, March 2-3 (2) Longevity Aspects Studied Genetic trends (correlation with birth year) Correlations of longevity with other traits on each nation’s scale Overall and adjusted for birth year Adjustment for yield traits

3 2001 R. L. Powell and P. M. VanRaden 2003 Interbull Technical Workshop, March 2-3 (3) Data Bulls born 1985-1994 in MACE longevity file (van der Linde and de Jong, 2003) Only data on “home country” scale (country with the most daughters) Yield, SCS, and conformation evaluations from Interbull (Nov. 2002) Some scales reversed to make positive always desirable for longevity and undesirable for SCS
