All InSire bulls can also be used in SireMatch matings! CRV breeding programme The CRV breeding programma aims to breed the best bulls in the world. CRV uses different sources to achieve this goal. For Holstein-Friesian bulls these are the Eurodonor programme, the US gene pool and CRV’s own herd, the Delta nucleus. From these starting points CRV is looking for bulls that can fulfill the breeding goal of CRV: “A healthy and long-lasting cow that delivers an optimal contribution to farm profits.”

CRV Holstein programme
From embryo to proven bull Every year CRV does genomic testing on 2,600 high level bull calves from the different sources. A selection intensity of 1 out of 15 results in the 170 best InSire bulls. These 170 are then progeny tested, which will result in proven bulls after the information from their daughters is known. The goal is to have 120 daughters in 100 herds after the bulls are progeny tested. In that way a reliability of >90% can be given to the bull’s breeding values and the InSire bulls can become proven bulls within 5 years.
