Top: New calves in maternity pen. US dairy farmers who sell into international markets are looking at integrating 3-breed crossbreds into their herds as one method of maximising their profits. Above: Adding genetics from other breeds can improve the functional traits and is becoming more popular in the US and Europe.
Higher lifetime profits were also realised due to the longevity of the crossbreds according to Leslie’s study. The three breeds he used to study the 3-breed or ProCROSS rotation are Holstein Friesian, VikingRed, and Montbeliarde. The rotation can start with either a VikingRed bred to a Holstein Friesian or the other way around starting with a Montbeliarde bred to a Holstein Friesian. The circular cycle of breeding VikingRed to Holstein Friesian then to Montbeliarde can also work in reverse. Leslie sees an opportunity for improving profits in dairy herds in the different marketing systems. “Crossbreeding simply provides the potential for more efficient and profitable production of milk solids regardless of the eventual use of those solids, either domestic or export,” he says.
