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. Discover how our bulls are delivering results today while building a sustainable future for dairy farmers.

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.

They are rare: bulls that combine high milk production with excellent component levels. With 922 kg of milk, +0.54% fat, and +0.19% protein (146 kg of fat and protein and €506 Inet), Delta Bridge P bridges the gap between high production and high components. Production isn’t his only strength. This new InSire bull also improves udder health (107) and hoof health (108). His daughters are expected to score 106 for resilience, meaning they adapt well to changing conditions.

For many breeders in the United States, he was the surprise of the most recent index release. Terra-Calroy Zuri, from CRV’s American program, received his first daughter-based breeding values in April 2025. With over 300 daughters contributing, Zuri rose to 3348 TPI and ranked 4th among daughter-proven bulls. With 1.37 PTAT, he is by far the best type improver among the top 5 TPI bulls.

The percentage of live-born calves in the Netherlands and Flanders from Holstein heifers has increased significantly over the past twenty years, from 81 percent in 2005 to 87 percent for black-and-white and 91 percent for red-and-white. This is evident from calculations by the Animal Evaluation Unit (EU department CRV) based on calving records.
