摘要

Multitrait, across-country evaluation procedures were adapted to improve reliability of survival breeding values by combining direct information with yield and functional traits: milk persistency, somatic cell count, fertility (male and female), and calving ease (direct and maternal). A set of bulls was selected from the Austrian Simmental population based on mean original reliabili- ties of at least 0.05 for yield traits or of at least 0.20 for functional traits. Only breeding values above these limits were retained.
