The April 2018 index run shows that the new NVI calculations, which are a better fit with the wishes of Dutch and Flemish cattle farmers, have impacted favourably on the rankings of CRV bulls. Many bulls boast outstanding production figures, with the high components currently in great demand.
Delta Treasure (Finder x G-force, 443 NVI) tops the list of black-and-white bulls. He transmits phenomenal longevity (+1248 days). His daughters will be highly productive (+1166kg) yet require little feed for maintenance (saving on feed costs € 31 per lactation). These credenti…read more ›
The following changes were implemented for the national breeding value estimation:
NVI for milk goal and dual purpose
Composites conformation dual purpose
Genomic breeding value estimation
Update base differences calving traits
1. NVI for milk goal and dual purpose
Following the discussion about the breeding goal conducted by GES and the studbook, the NVI will be adjusted. There will be an NVI for milk goal for animals that are published milk goal base black and milk goal base red. In addition there will be an NVI for dual purpose.
The buzzword in breeding – in addition to health and lifetime production – is feed efficiency, an aspect where the Netherlands leads the field. CRV collects feed intake data and the GES will publish the ‘feed costs for maintenance’ breeding value. According to CRV’s Gerben de Jong ‘This represents the next revolution in breeding after the use of genomics’.

Farmers with many cows that achieve high lifetime production, are convinced that this high lifetime production is in the genes. The Knoef and Winter families tell all about their vision of high lifetime production.
Big Boukje 192 produced a whopping 208,000 litres of milk with 4.64% fat and 3.86% protein. The cow, which belongs to Jos and Ingrid Knoef in Geesteren, is the champion par excellence of lifetime production. She reached the age of 19 years old, calved an impressive 15 times and also obtained an exterior score of 90 points. Jos is convinced: ‘This high pro…read more ›
The USA-based index run shows a great lineup of CRV bulls to improve production efficiency in the herd. Draftking, Liner and Hotline are high ranking, genomic tested bulls, while CRV also has a great selection of daughter proven bulls to support farm economics.
Holding a skyhigh position in the US rankings, we present Peak Draftking (Bourbon x Mogul Delta, 2891 TPI). With +1766 lbs for milk and positive fat and protein contents he scores a great Net Merit$ of +1008 and an excellent +12% for Better life Efficiency. This means that during their lifetimes Draftking’s d…read more ›
