MASTERRIND April Sire Summary 2021

News around the German Holstein breeding value evaluation

For the first time the German health traits RZcalffit and RZhealth are included in the new designed total merit index RZG. Additionally, the body index is included in the type composite, while the direct calving index RZKd became part of the calving composite as well. Through these changes the health traits are counting up for 49% in the total merit index. The new RZG structure as well as the annual base change in Germany (-6.1 RZG points on average for all Black and White Holsteins; -5,7 for all Red and White Holsteins) has led several changes in the German top rankings.
