Abstract

Product moment correlations between breeding values for length of productive life (LPL) adjusted for milk production and diseases, as predicted in a failure time analysis, and breeding values for other important traits were calculated for Swedish dairy bulls. The other traits were yield of protein, mastitis resistance, somatic cell counts, resistance to "other diseases", udder conformation, and stayability. Most correlations were low (<0.05) indicating that adjusted LPL may be a useful addition to the directly recorded functional traits. However, breed differences were found that need to be considered and investigated further
