The aim of the project is to develop and update the mathematical and statistical procedures for the processing of outputs from the performance testing of beef cattle and to incorporate the acquired genetic data into the national breeding system and to the systems of routine genetic evaluation of animals. Emphasis is placed on the development of genetic evaluation for new traits and on the introduction of new traits into performance testing. Furthermore, the project focuses on the use of genotyping of animals for prediction of genomic breeding values, which will lead to higher efficiency and reliability of animal selection.
