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.

Higher reliability at young age. Before genomic information was used, the only way to predict the potential of the newborn animal was based on a calculation of the parents’ average. Nowadays, the information collected from the markers ensures a better estimation of the calf’s potential at a very young age. Where the reliability of a young bull would be 35% in the past, it is now around 65%. The bulls that are selected on genomics are called InSires at CRV. pedigree EBV

Reliability of genomic selection Since the introduction of genomic selection, the first batches of InSire bulls received their breeding values based on progeny testing and showed that their genomic and daughter proven breeding values are very close to each other. This means that the InSire breeding programme delivers very reliable proofs. The figure below shows how close the progeny tested breeding values for NVI are to the InSire breeding values.

‘It’s in the genes’. These words are not only used for people with remarkable characteristics, but are also true for breeding bulls. The genetic information of an animal is spread on the DNA in thousands of genes. Genetic markers are small recognizable pieces of DNA that lay close to the genes. They have approximately the same transmitting ability as the genes they are close to. A marker (or SNP) therefore, provides information about those genes and the genetic potential of an animal.

EuroGenomics Since 2009 several countries in Europe work together to increase the reliability of genomic breeding values. The bigger your reference population of bulls is, the higher the reliability of the tested bulls will become. The data of about 20,000 HF bulls is in the EuroGenomics database, making it the biggest reference population in the world. country

Advantages of genomic selection • Faster genetic gain (30-40%). • InSire bulls are of higher quality than young sires in the old system. • A higher variety in used pedigrees. • More diversity in bulls. • Selection at young age. • New families can be discovered.
