Improvement of genomic chip
The improvement of the genomic chip in the USA has caused quite some changes in genomic proofs. By including more markers in the genomic chip (from 60K to 80K) the reliability of genomic proofs has slightly increased. Although there is no obvious trend what the result is for individual bulls. For the daughterproven bulls there are no big consequences, however the top young genomic bulls went down in general just a little and some single bulls some more.
Proven bulls
At the proven bulls in the USA there are no big changes in the top 10. EDG Rubicon is still on top, highest new bull this run is S-S-I Montross Duke, at the 5th position with 2747 TPI. His 3/4 brother S-S-I Montross Jedi, in August starting at spot 7, added over 1000 milking daughters to his proof, dropped 69 points TPI and is now out of the top 10. Also Bacon-Hill Pety Modesty doubled his number of daughters and had to leave a spring, ranking now 35th with 2598 TPI.
Genomic bulls
Although the change of the genomic chip, the highest genomic young sire, a Mr Rubicon Dynasty x Josuper, is still breaking the barrier of 3000 gTPI. Young sires maintaining or slightly increasing their genomic proofs are AltaLawson, ABS Crimson, Discjockey and Solution. Biggest drops this run are Skywalker (-80), Kenobi (-64) and Aristocrat (-51).
