For traits with low heritability, it takes longer for adjustments in breeding objectives to be reflected in genetic trends. Female fertility was weighted much more heavily when the breeding objective was formulated five years ago. However, a strong effect in the genetic trends is not yet evident. On the other hand, the trend is strongly positive in udder health as well as in conformation traits – especially in the udder. The development of teat distribution at the rear and teat position is under constant review. The functionality of the teats for milking must also be guaranteed in the future, not only in farms with AMS.
