PROOF RUN 4/2025 US-WERTE

While the switch to the single-step method has brought about a lot of movement in the German breeding value estimation lists, the movement in the US values ​​is due to the five-year baseline adjustment, which has now left its mark. The shift in the baseline year of the reference population from the 2015 birth year to the 2020 birth year has resulted in some changes due to breeding progress. For example, the adjustment in milk yield was a decrease of 750 lbs. The GTPI values ​​have increased slightly.
++ IMPORTANT: The change comes from the genetic comparison basis. The genetics and heritability of the individual bull remain unchanged - AND: The bulls whose milk breeding value decreased by less than 750 lbs have effectively increased in production!
++ QUALITY has performed excellently with its first milking daughters and has effectively increased by 100 lbs. This all-round sire, which is becoming increasingly popular with us as well, consistently produces medium-sized, broad, and functional commercial cows, should be included in every AI container and used widely.
++ BOLOGNA and BERGAMO, the full brothers who come from the same cow family as our long-running GLAMOUR RED, continue to improve with the adaptation and, with their balanced inheritance profile, can be used widely and without problems.
++ MASERATI, whose first daughters will calve in the fall and whose cattle are particularly noticeable in the young cattle pens, can maintain his values ​​just as stable as the new homozygous polled bulls NETFLIX PP RF and MOJO PP RF.
