A remarkable milestone for De Oosterhof DG Rose RDC VG-89! The seventh-lactation Rubicon daughter of Sudena Holsteins has recently surpassed the impressive 100,000 kg milk mark. A testament to her outstanding production and longevity, but also a fitting moment to celebrate a cow whose influence on (Red) Holstein breeding extends far beyond her own performance.
Rose RDC was purchased as a fresh 2-yr-old by Sudena Holsteins. What followed was a highly successful breeding career that would establish her as one of the most influential red carrier brood cows in modern Holstein breeding. With at least seven sons entering AI and almost twenty grandsons following in their footsteps, Rose has become a true cornerstone of an internationally recognised breeding dynasty.
Among her notable sons are Sudena Safari Red (s. Spark Red), Cristella Real Red (s. Swingman-Red) and Sudena Roderick (s. Gonzales). Yet, her influence through the female line has arguably been even more remarkable. One daughter in particular has played a major role in taking the Rose family to the international stage: Lakeside UPS Red Range VG-86 (s. Mr Salvatore RDC).
Red Range developed into an exceptional brood cow at Koepon Genetics and was named o.a. Global Red Impact Cow by Holstein International in 2021. Her breeding record is impressive, with no fewer than sixteen sons and thirteen grandsons entering AI. However, her most influential offspring is undoubtedly 3STAR OH Ranger Red (s. Rubels-Red). Bred by GenHotel and De Oosterhof, Ranger Red rose to the very top of the international Red Holstein genomic rankings and established himself as a highly sought-after sire worldwide. His full brothers, Koepon OH Ryder Red and Koepon OH Robin Red, have also made their mark in AI programmes internationally.
This branchy continues to make its presence felt in the next generations. Among the notable sires tracing back to this influential cow is DG DV Rammstein Red, further demonstrating the lasting breeding impact of this remarkable maternal line.
With a lifetime production of 100,032 kg of milk, featuring impressive components of 4.73% fat and 3.56% protein, Rose has certainly proven her value in the milking parlour. Combined with her outstanding transmitting ability and an impressive legacy of influential AI sires, she represents a rare combination of production, longevity and exceptional genetic impact.
For Sudena Holsteins, the purchase of Rose has proven to be an extraordinary investment. More than just a 100-tonne cow, De Oosterhof DG Rose RDC has become a true foundation cow whose influence continues to reach breeding programmes around the world.
