Longevity was evaluated from breeding view as production longevity, i.e. from calving to culling. For prediction of genomic breeding value (GEBV) was chosen repeatibility model in ssGBLUP. Fixed effects were interaction herd*year*season and milk production. Random effects were additive genetic effect, permanent environment effect. Model without and with weights (i.e., weighted analysis) was tested.
