INTERBEEF BREEDING VALUES ON DFS SCALE

Although NAVs member countries have national official genetic evaluations for beef cattle they participate jointly in Interbeef.

Official Interbeef breeding values are so far only available for Adjusted Weaning Weight (AWW), Birth Weight (BWT) and Calving Ease (CAE)  direct and maternal effects for the breeds Charolais, Limousin and Simmental. New breeding values are published twice a year (March and November) and the newest results can be viewed in top lists reached by the links below.

Charolais  (Participating countries: Czech Republic, DFS (Denmark, Finland, Sweden), France, Germany, Ireland, Switzerland)

Limousin (Participating countries: Czech Republic, DFS (Denmark, Finland, Sweden), France, Germany, Ireland, Switzerland, United Kingdom)

Simmental (Participating countries: DFS (Denmark, Finland, Sweden), Germany, Ireland, Switzerland)

For each breed there are three different top lists, so each excel file has three different sheets. In the header of the top lists you can see the publication rules for direct and maternal breeding values. Currently, top lists are sorted based on the breeding value for AWW direct and only include animals with a minimum breeding value of 115 for AWW direct.

A. Internationally official males

  • High-reliability bulls that reach the requirement set by Interbeef to be internationally publishable in all member countries

B. DFS official males

  • Bulls from list A if they are born in DFS and other bulls with official breeding values in Denmark, Finland or Sweden

C. DFS official females

  • Cows with official breeding values in Denmark, Finland or Sweden

 

Interbeef breeding values on DFS scale are standardized so that animals with AWW record born 3-8 years before the date of evaluation has an average breeding value of 100 and a standard deviation of 10. That is similar to what is used nationally in Denmark, Finland and Sweden.

To limit the size of the top lists only animals with a breeding value for AWW direct of at least 115 is included. In the future we will improve the publication by creating a search page where all animals and additional information can be included.

Important to remember is that Interbeef evaluations are only available for some economically important traits some of which are analyzed in single-trait models whereas the official evaluations in Denmark, Finland and Sweden, respectively, are multi-trait models also including several other traits. Further, Interbeef evaluations also uses information from relatives in different countries. Therefore the ranking based on Interbeef breeding values can differ substantially from national rankings.
