    Delta Vikram, a modern breeding bull from a historic cow family

    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.

    Delta Bridge P - Combining high yields with rich components

    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.

    In twenty years, 6 percent more live-born calves from heifers

    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.

    Anyone wanting to envision the daughters of Delta Party P should look at the beautiful dam of this new red-and-white InSire bull. Delta Ryfke P (by Solitair P) was classified as a heifer with 87 points for overall conformation, including the maximum score of 89 for type and udder. She also received a linear trait score of 9 for rump width and rear udder height, and 8 for rib structure and fore udder attachment.

    Favorite bull dam: Delta Tulip P

    Ten years ago, D’n Driehoek Delta Teuntje was the first “Teuntje” in Beers. Three generations later, Delta Tulip P is one of the standouts. “Tulip doesn’t give up easily, like all the Teuntjes. They’re cows with a ‘no-nonsense, get to work’ attitude,” says Jens Hermanussen.
