Abstract

A model is described for evaluating dairy sires for the conformation of their daughters accounting for age at classification, year, classification of the dam, genetic trend, and sire effects. Results of the application of this model to two data sets are presented. Estimates of genetic trend for type traits indicated at least twice as much progress is being made for type as for milk production.
