International type evaluation of dairy cattle

摘要

The World Holstein Friesian Federation type harmonisation programme has been introduced by almost all countries for the type evaluation of Holstein dairy cows. The quality and robustness of the programme have been demonstrated in the Multiple Across Country Evaluation (MACE) for type evaluations, producing inter-country correlations, which at one time were considered impossible to achieve. ICAR has adopted the principle of the WHFF type harmonisation programme and it is logical, considering the quality of the results, to fully integrate the recommendations of both organizations into an international standard for type evaluation, administration and presentation.
