The purpose of the study was to determine the association between each of heifer and first lactation traits with each of longevity and lifetime production traits of 2914 Friesian cows from 1979 to 2013. Correlations between each of heifer and first lactation traits and each of longevity and lifetime production traits were estimated. Genetic correlations between both LLNO and PL and each of AFB, ASB and AFC were strong negative, however, correlations between HL and same heifer traits were strong positive. Strong negative genetic relationships between NSC0 and each of LLNO, HL and PL, however, correlations between each of CR0 and SP0 and each of LLNO, HL and PL were strong positive. Genetic correlations between age traits and each of lifetime production traits were positive. Genetic relationships between first lactation fertility traits and all longevity traits were strong negative, however the genetic correlations between first lactation production traits and longevity traits were strong positive. Medium to high genetic relationships between first lactation fertility traits and lifetime traits were obtained. Genetic relationships between first lactation production traits and lifetime production traits were strong positive.
