Suitability for automatic milking systems In August 2014, VIT released a new breeding index specifically for farms with automatic milking systems (AMS) in order to facilitate selection of particular bulls. The RZRobot is built from the following traits: milking speed (≥ 94), somatic cell count, feet & legs, udder, rear teat placement (≤ 106) and teat length (≥ 94). These six traits have...

Genomic breeding values Since August 2010, genomic breeding values for Holsteins (Black & White and Red & White) have been official in Germany. In fact, they are among the most reliable genomic breeding values worldwide because they are based on the EuroGenomics training sample (reference population), containing more than 28,000 reliable daughter proven and, at the same time, genotyped...

Milk production and udder health Since 1997, breeding values for milk production and somatic cell score have been estimated directly on the basis of daily yields measured monthly on the farms using a test day model. Therefore a summary or expansion for lactation yields is not carried out. Correction for all non-genetic effects is optimal because performance is compared within herd-test-day, i.e....

Total Merit Index RZG The total merit index RZG, includes all important traits according to their economic importance. In 1997, Germany was one of the first countries to have a real total merit index with production, conformation and functional traits like longevity and fertility. Since the last adjustment in April 2008, the functional traits have been weighted at 40 %, conformation 15 % and...

Guarini is the new No.1 among the Holsteins. Heavily used genomic bulls now have a proof with daughters. The annual base shift shows progress in breeding for longevity. Toplist Holstein (daughter proven bulls)Toplist Red Holstein (daughter proven bulls) In this April proof run, the annual base shift has been carried out for all relative breeding values. All A.I. bulls born between 2003 - 2005...

There are now only active sires in the official top lists for the highest daughter proven bulls according to RZG. On the whole, because of this, more than the half of the bulls listed previously are no longer listed and interesting active sires, therefore move up. In addition there is a new list, containing all of the very reliable second crop bulls. The previous list leader, Snowman, can now be...
