Just as the Eurostar train transports passengers at high speed, Delta Eurostar rapidly delivers cows that perform at the highest level. This new InSire sire transmits high milk production (+1,152 kg) with strong components (+0.41% fat and +0.20% protein), resulting in +156 kg fat and protein and €549 Inet. He also adds +591 days of longevity. This means his daughters will remain productive for an average of ten months longer, yielding over 10,000 kg of additional milk throughout their lifetime. Eurostar also achieves an impressive +19% CRV Efficiency score.

Sire bull Delta Marcher PP is a strong example of international gene exchange in Holstein breeding. His sire, Marsrover PP, is a Delta bull with a German sire from an originally American cow family. His dam descends from a German cow family that was developed with the influence of Dutch sires. The granddam of Marcher PP is HWH Ella P, from the successful German ZT Elaine cow family. No fewer than seven of her – polled – sons were used at various AI organizations. Ella is a daughter of Caudumer Solitair P, bred in Friesland in the Netherlands. From this outstanding brood cow, CRV purchased a heifer calf by Poppe Freestyle, another Dutch sire with an international profile. This heifer, Farina P, has since calved and is now working at CRV’s test farm De Barendonk. Her first lactation is projected at nearly 13,000 kg of milk. She is showing remarkable progress: at 221 days in milk, she produced 48 kg, her highest daily yield to date. “And she is already pregnant again,” reports Jens Hermanussen, who describes Farina P as a dairy-typical heifer with a strong udder, excellent legs, and outstanding production.

Every dairy farmer strives for a herd that achieves efficient production with little hassle and labour. Good fertility is a prerequisite for this. Breeding can make an important contribution here. CRV bulls prove in this index run that breeding for CRV Efficiency goes hand in hand with good fertility. This not only results in higher returns but also more job satisfaction and ease of work.

CRV’s Fleckvieh proven bulls are bred to deliver it all – high production, robust health, and functional conformation in one complete package. Thanks to CRV’s focus on balanced breeding, these sires excel not only in index performance but also in key functional traits such as strong udders, sound feet and legs, and longevity. The result is a lineup of bulls that help farmers build productive, trouble-free herds for the long term.

At the turn of the century, cows from the Bûtemare Ida family ranked high on the Dutch cow indexes. Back then, breeding focused mainly on Inet (economic index), while traits like health and longevity were still in their early development. Now, more than 25 years later, this same Ida family is back in the spotlight - this time with a bull that scores exceptionally well not only for production, but also for health, longevity, and the modern breeding goal of feed efficiency.

Hoof problems are a major source of frustration and cost for dairy farmers. They result in direct expenses for treating lame cows and, more importantly, in indirect costs due to lost productivity.
