The sky-high components of InSire Top Bull De Leenhorst E-Profit do not come out of nowhere. The cow family behind the bull is responsible for high protein percentages, generation after generation. On top of this, dairy farmer Jan Schieven has been using bulls that guarantee premium milk for thirty years.
“If you want to achieve something in breeding, you have to be consistent,” says dairy farmer Jan Schieven with conviction. In partnership with his wife Anja and with the help of his parents, he runs a dairy farm in Baak in the province of Gelderland with around 100…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.
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’.
