2001R. L. Powell and P. M. VanRaden 2003Interbull Technical Workshop, March 2-3 (2)
Longevity Aspects StudiedLongevity 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
2001R. L. Powell and P. M. VanRaden 2003Interbull Technical Workshop, March 2-3 (3)
DataData
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
