High offspring from OH DG Rose RDC VG-87!

De Oosterhof (OH) DG Rose RDC VG-87 by Rubicon originates from the Holbra branch of well-known Mark Prudence family. Her dam by Aikman was purchased by DG and De Oosterhof Holsteins and they in turn consigned Rose VG-87 to the March 2016 Vekis Sale on which she sold to the well-known Bouw Holsteins herd. Mr. Jan Bouw flushed her extensively and Salvatore embryos resulted in very high g TPI and g RZG offspring. One of the resulting RED Salvatore heifers was purchased back by De Volmer Holsteins and DG and from this Salvatore, Lakeside UPS Rosylane RED, the very first RED heifers have been born. These RED heifers are sired by Delta Jacuzzi-RED, a very high g NVI and g RZG bull from CRV. The highest of the first two RED Jacuzzi heifers is De Volmer DG Rozanne RED. She looks real good, is contracted by Genetics Hokkaido already and scores a shattering 442 g NVI along with 2500 g TPI! Rosylane herself is due later this year. DG and De Volmer Holsteins hope future calves will have similar looks and results as these first two!

A transmitter of components und great udders!

Roccafarm Beacon Chrissy was purchased as a calf from Roccafarm, Belgium by DG and Albero Holsteins about 7 years ago. As a high genomic tested maiden heifer, this Beacon x Ramos x Outside daughter was flushed extensively. She freshened and classified VG in the herd of Broeklander Holsteins and continued to be in heavy use as a bull mother, now for CRV. Several calves and meanwhile granddaughters are currently in full use in the CRV nucleus. Today we know that her sons Checkmate RDC (by Aikman RDC and at RSH), Blooper (by Boss , AI Total)  and Gandhi  (by Galaxy, VOST) deliver their genomic promises of high components and great udders. Beacon Chrissy, granddaughter of the prolific Larcrest Outside Champagne EX-90, proved to be a successful source for fantastic components and udders and several daughters milking in several herds also show the same characteristics. We congratulate the owners of successful Chrissy offspring and expect to hear more good news from the Chrissy’s in the near future!

DG OH Rubels RED

Rubels-RED is a phenomenon. The highest red and white g TPI bull of the breed and the most complete red and white bull ever! Rubels-RED will soon be available through ABS, represented in the Netherlands by Fa. Heemskerk. He is a son of Endco Argo RDC (a Silver son from the Apple line) from a high-producing, good looking Rubicon daughter who in turn received the red and white factor from her mother’s father Aikman. This Aikman is also the mother of the high g TPI, g RZG and g NVI bull Alaska-RED and goes back via a Planet on the world famous Rainyridge Tony Beauty 5E EX CAN. Rubels-RED is an excellent example of the power of the breeding program of DG and De Oosterhof Holsteins.

Rubels-RED has a very complete profile and is carrying the Kappa Casein BB variant as well!

DG OH Django – Topstone

The Oosterhof Holsteins from Willem Scholten from Ambt Delden (prefix OH) and Diamond Genetics together bought Aikman daughter Telgter Aikman Doreen at the 2014 Holland Masters Sale. Aikman Doreen had a good DNA breeding value, carried the red and white factor and she came from the very successful Durham Prudence line of Holbra Holsteins from Laren. The bull DG OH Django was born in 2017 from a Rubicon daughter of this Aikman Doreen. Django’s father is Bomaz AltaTopshot and Django was sold to Masterrind in 2018. The bull has since been renamed Topstone and meanwhile Masterrind has made his semen available. In addition to an excellent profile and a current g RZG of 158, this bull also has a g TPI of 2732 and a g NVI of 342 with a whopping 450 € INET. In addition to appropriate breeding values ​​for the frame characteristics, his profile stands out for excellent breeding values ​​for cell count and daughter fertility. Topstone has a slightly different pedigree and is supported by a deep, high-component and conformation cow family. Diamond Genetics wishes Masterrind every success with the sale of semen from this strikingly complete bull.
