The April index run demonstrates CRV’s progress in breeding for efficient cows with great longevity. Mint, Dax, Worldcup and Hongkong PP are amazing bulls for Fleckvieh breeders who want to utilise the full potential of their farms’ production capacity.
Mint (Manigo x Rau, 132 TMI) was already awarded proven Fleckvieh bull status in December 2017. In the April index run, Mint has added nine points to his total merit index and boosted his milk index (123) by six points, giving him a great efficiency score (+11%). His outstanding conformation rating shows excellent fe…read more ›
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.
Traits including production, longevity and fertility were already part of the NVI merit index. GES will be expanding this formula from April to incorporate hoof health and feed efficiency. In addition, a parallel version of the NVI will be published.
Alongside the NVI for dairy breeds, the GES will now publish NVI calculations for dual-purpose breeds. The breeding value for longevity has also been revised, resulting in more stable breeding values and greater reliability.

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’.
