The August index run shows CRV bulls that make herds healthier and more efficient. The speed of genetic progress keeps accelerating and farmers are reaping the benefits. Nowadays, farm management has become even more key to profitable farming. Herd advisors give specific advice that helps choose sires that suit the goal’s individual farmers are attempting to achieve with their herds, whether this is increasing the components, increasing the kilos of fat and protein, or other goals. After this index run, there is another wide choice of bulls at CRV that can help boost t…read more ›
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…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.
