    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.

    Breeding for methane reduction gaining momentum worldwide

    With a heritability of around 20 percent, methane production is a trait that can be successfully improved through breeding. Internationally, extensive research is being conducted into the relationship between genetic predisposition and the production of this powerful greenhouse gas. However, the potential of breeding for lower methane emissions will only be fully realized if farmers receive a financial reward for their efforts.

    SiryX brings peace of mind to your business operations

    Jorick Tromp (32) still remembers it from his younger years: when a top cow calved of a bull, he used to be very disappointed. “When CRV introduced sexed semen (SiryX) to the market, we started using it on a few cows. We wanted to know how fertile the semen would be, and we were curious whether we would really get at least 90% heifer calves,” he says. “But it easily exceeded 90% heifer calves in his experience. And the fertility of SiryX proved hardly inferior to that of conventional semen.

    Sterksel Simson shows the value of genomic selection

    Sterksel Simson would have been an anonymous bull calf if CRV had not used genomic selection. The story of this InSire bull began with the purchase of an anonymous heifer from the dairy farm of Vecunda Vee CV in Sint Anthonis (the Netherlands). This daughter of Delta Skyline caught CRV’s attention because her genomic breeding values were sky-high compared with her expected values. The heifer was moved to CRV’s test farm run by Hans van Middelaar, who named her Sterksel Simone.

    Lowlands Solaris puts complete, hardworking dairy cows in the spotlight

    “The Bertha family? They’ve been on our farm since 1980 and have simply performed well,” says André Frijters from the Netherlands. The dairy farmer never imagined he would one day breed an AI bull from this family, until he got a message from CRV asking if he would take a hair sample when the third calf of Listrotto daughter Bertha 193 was born.
  • Step-by-step plan genomic testing

    Step-by-step plan genomic testing

    Which calves will grow into strong and productive cows? With genomic testing, this can be predicted at an early stage. A genomic test analyzes a calf’s DNA and compares it with the genotypes of 1.8 million cattle in a large database. This makes it possible to predict which animals will perform te best. Below you can find a step-by-step plan regarding genomic testing.
