  • Delta Tallon P shows the Jane family’s talent as a heifer bull

    Delta Tallon P shows the Jane family’s talent as a heifer bull

    For years, the Jane family has been one of the most influential cow families in CRV’s breeding program. Several current InSire bulls trace their bloodlines back to foundation cow Groenibo Stellando Jane from the Borst-Beemsterboer family farm in Heerhugowaard (The Netherlands). She was the dam of Groenibo Bram and produced nearly 110,000 kg of milk during her lifetime, with 4.44% fat and 3.54% protein. “Stellando Jane was smaller than average but strongly built. She was a powerhouse, a trouble free farmer’s cow with strong legs and a highly functional udder. The Janes are persistent, high-producing grazing cows, and Stellando Jane fit that picture perfectly,” breeder Sjon Borst once said about her.
  • Delta Caliber breeds hardworking cows of the right caliber

    Delta Caliber breeds hardworking cows of the right caliber

    Cows like Gastelsveer Jeltje 97, bred by the Van Merriënboer family from Oud Gastel (The Netherlands), demonstrate the strength of an open breeding program. The Ranger daughter was once the heifer with the highest NVI-score in the Netherlands, was purchased by CRV, and housed with Arjen Vernooij in Schalwijk (The Netherlands). There, the Jeltje family quickly developed into one of the largest cow families at Hedra Holsteins.
  • Genomic bulls live up fully to expectations once daughters start milking

    Genomic bulls live up fully to expectations once daughters start milking

    Thanks to continuously improving breeding value estimation, the reliability of genomic breeding values for bulls has increased significantly in recent years. As a result, the breeding values of daughter-proven bulls now bring few surprises. Genomic bulls are fully meeting expectations. This index run once again provides proof with the daughter debuts of bulls such as Delta Borax and Delta Appetizer, and the increasing reliability of, among others, Delta Emoji P and the Delta brothers Dolmen and Flagstone. This promises a lot for the youngest generation of genomic bulls, which shows an unprecedented high level.

    CRV strengthens Fleckvieh portfolio with balanced genetics for functional and long-lasting dairy cows

    CRV is proud to present its latest Fleckvieh line-up, highlighting a well-balanced portfolio designed to support modern dairy farming worldwide. The focus remains on the traits that ensure cows are productive, long-lasting and functional: high and persistent milk production, strong feet and legs, well-attached udders, reliable udder health, and solid daughter fertility. All these traits contribute to cows that perform consistently over multiple lactations and perform efficiently in a variety of dairy farming systems.
  • Hereditary characteristics: How CRV handles them

    Hereditary characteristics: How CRV handles them

    CRV places great importance on healthy and efficient cows and reliable breeding. That is why we handle hereditary defects in a conscious and transparent way. Thanks to genomic selection, we are increasingly able to identify hereditary traits. This also means that new genetic defects are occasionally discovered. For the Holstein population, two hereditary defects have recently been identified:
  • More return with the milking robot index

    More return with the milking robot index

    Breeding helps reduce labor and increase the return on investment in automatic milking. Selecting on the milking robot index results in more kilograms of fat and protein per robot per day, heifers that adapt to robot milking more quickly, and a shorter interval between milkings while maintaining or even improving udder health.
