Breeding for improved health and efficiency works

Analysis of the performance of cows in the herd of producer Troels Bjørn located in Hobro, Denmark, shows that using breeding indexes for health and efficiency pays off. Leading cows on the Better Life Efficiency index, developed by CRV, produced over 1,500kg more milk compared to their herd mates. The top cows for the Better Life Health index were significantly healthier. They showed less cases of mastitis, a lower somatic cell count and a shorter calving interval.

Breeding for improved health and efficiency works. This is shown by an analysis of the performance of…

New NVI highlights quality of CRV bulls

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…

News indexrun April 2018

The following changes were implemented for the national breeding value estimation:

NVI for milk goal and dual purpose
Composites conformation dual purpose
Longevity
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.

April indexrun: new additions to the NVI

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.

High lifetime production is in the genes

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…
