Correlation of Longevity Evaluation With Other Trait Evaluations From 14 Countries : Correlation of Longevity Evaluation With Other Trait Evaluations From 14 Countries


Longevity Aspects Studied : 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


Data : 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
