Vekis DG Menko is a Missouri son out of DG Meridian Lizzy, then we find Vendairy Snowman Lidia 4 VG-88. He reached to an impressive +144 RZM with +119 RZE resulting in +143 RZG.

Delta Bridgett and her dtr DG Biene continues refreshment for R&W

If you would take the progress made in the recent years in the Black and White population because of bulls such as Superstition, Supersire and Delta it is behond imagniation. Not one breeding programm in the world does not want these bulls in their programm, every sire line up in the world is having some of these genes running trough multiple bulls in their line up, often some of the very best. Trough the excellent 91 scored Delta daughter these valuable genetics are now coming available for the Red & white population. Her daughter DG Biene is now continuing this line with maybe the most suprising black and white bulls from the last two index runs Burley. Als DG Biene is a Red carrier and trough her the valuable Burley genes will also come available fort h world wide Red & White population. She has valuable pregnancies incluing the breed leader Captain, this to also secure this top Black and White bull for future the Red & White genetics.

Superstyle and Supershot a special pair of brothers.

In the spring of 2013 Supershot git his first number going claiming the world wide number 1 Net Merit position. Now in 2020 we can say Supershot met all expectation. With over 1600 milk a 2,76 SCS and Positive DPR he still beats many of he current stars in one of these fields. He is today’s Europe’s  most influential bull to have ever come to the Holstein scene.
Cogent did not only acquire Supershot but also his full brother Superstyle, now looking back a very wise decision. If we look at Superstyle his proof in the Netherlands he is leaves with 235 NVI  his brother Supershot (257 NVI) in front, but looking at the production side Superstyle certainly shows impressive number resulting in 367 INET. In Germany Supershot now had 146 GRZG and also three sons (Topshot, Windmill and Estetian) in the top 10 daughter proven list! The influence and legacy of Supershot will continue trough his so many sons and grand sons.
