Abstract

A genetic evaluation of dairy sires based on survival analysis of the longevity of their daughters was implemented in France and in Austria. The model allows the inclusion of censored records and a correction of length of productive life for changes in culling policies over time and for voluntary culling due to low milk production. It is applicable to very large datasets.
