Dutch genomics online

21 Aug '18 Genomics

The Dutch genomics breeding values (females) of August are added to the GenHotel site. Only on GenHotel you can find the top 100 GNVI B&W and R&W.
The B&W list is headed by Rush Hour daughter Liesje 1323 owned by the Priems family. GenHotel members that own high heifers in this list are K&L, Caudumer Holsteins, Riethil Holsteins, Van het Zomerbloemhof and Willem’s Hoeve Holsteins.

R&W

The R&W GNVI list is topped by Poppe Kanu 8914 Red of Poppe Holsteins. This Pace-Red daughter of the Wilder Kanu 111 RDC VG-88 family scores +359 GNVI. Kanu 8914 Red also offers +163 GRZG on German basis and is one of the most interesting red heifers in Europe. The dam to Kanu 8914 Red, Wilder K41 RDC, is sold through the GenHotel Selection Sale to Poppe Holsteins.
Poppe Holsteins has with Poppe Fienchen 1569 Red (+332 GNVI; Born P RDC) and Poppe Fienchen 1270 Red (+331 GNVI; Norbert) two granddaughters of Poppe Fienchen 803 RDC VG-86 (Danillo x Poppe Fienchen 580 RDC VG-88) in the top of the list as well. In the top 100 you will also find heifers owned by GenHotel members such as Aalshorst Holsteins, K&L, Schuit Holsteins, Red Rocks Holsteins, Caudumer Holsteins, HM Holsteins, Buitenlust Holsteins, De Sanderij, Drouner Holsteins, Poppe Holsteins, Beeze Holsteins and Melkveebedrijf De Oosterhof.

Aiko & Lol

Also among the top 10 is Drouner Aiko 1582 Red (+338 GNVI; #9) owned by Drouner Holsteins. The pedigree of this Alaska Red daughter goes via an RDC Brasil RF daughter back at Drouner AJDH Aiko 1288 Red VG-88, the Honourable Mention Junior 2-Yr Old NRM 2017!
Aalshorst K&L Lol 3 P Red (+321 GNVI) is among the top 30 GNVI. She is the #7 GNVI Polled. Lol 3 P Red is owned by K&L and Aalshorst Holsteins and her dam is a VG-85 Apoll P Red granddaughter of Caudumer Lol 305 PP Red VG-87 (Magna x Caudumer Lol 292-Red P VG-87).

August versus April

Some of you might have noticed that the GNVI of August are on average slightly lower than the GNVI of April. That is correct. The average change between the August and April GNVI data in the top 2% NVI is -22 points GNVI, but some heifers show huge differences. This is due to an adjustment in the GNVI formula which reduces the influence of longevity, foot health, interval calving-1st insemination, and udder health.
In the table below you can find the from top 2% heifers on NVI basis the genomic tested heifers. These are ranked (1st column) by their GNVI of April 2018 in in groups of 25 points GNVI. In the 2nd column you find the number of heifers in this group and in the 3rd column the average difference in GNVI (August 2018 – April 2018) based on the heifers in column 2. In the columns 4 (maximum) and 5 (minimum) you can see the biggest differences.

Pay attention; we don’t have all genomic data available. Therefore these averages are based on the top 2% of the population. We do believe that these differences give a good indication of the changes in GNVI between April and August.
