Walter is also an advocate of the benefits of crossbreeding. Research shows that crossbred cows are also more sustainable than purebred Holsteins, with improved feed efficiency, vitality, fertility, health, and longevity traits – all thanks to the free benefits of heterosis.
Heterosis is the increase of favourable characteristics of a hybrid organism over those of its parents. It is the opposite of inbreeding and happens when two unrelated breeds are crossed.
“The ProCROSS system has two dominant success issues, which are heterosis and the use of three of the highest-producing dairy breeds,” explains Walter. “In terms of sustainability, the ProCROSS cows are 8% more feed efficient,” he adds.
Walter has some good advice for farmers in The Netherlands and worldwide who might be considering a switch to the ProCROSS system. “Firstly, we audit the dairy farm to get better advice on what path to follow,” he explains.
“The choice is not only influenced by financial reasons; the farmer should also feel attracted to these concepts. Without VikingGenetics these concepts are impossible to use, and we know hundreds of farmers who every day demonstrate their farms are better and the cows are happier by using our genetics,” he says proudly.
“Some areas in the EU focus on challenging farmers to have a more sustainable production system. Our concepts are better for the environment and for the income of farmers. I foresee excellent growth in the market shares of both ProCROSS and VikingJersey over the next few years,” he ends.
