Wolfova, M. | Wolf, J. (Vyzkumny Ustav Zivocisne Vyroby, Prague-Uhrineves (Czech Republic))
An overview of the state of art in applying multitrait animal models in pig breeding in different European states (Austria, Czech Republic, Denmark, France, Slovakia, Sweden, Switzerland, Norway, federal states Bavaria, North Rhine-Westphalia and Saxony of Germany) and Canada is given. Traits and models used for genetic evaluation differ considerably between states. In all states repeatability models are used for reproduction traits, in Czech Republic and Slovakia the first litter is considered as a separate trait. The number of traits included in the total breeding value ranges from 2 to 7, where separate total breeding values for production traits and for reproduction traits are often defined.
