2 100-tonner cows

40,000 100-tonner cows in 30 years

The accolade ’100-tonner’ has been around for 30 years in the Netherlands. In that time more than 40,000 cows have smashed the magic barrier of 100,000 kilos of milk production, including members of Flemish herds. The number of 10-tonners is also growing rapidly. Last year, the tally clocked up the 3400th cow with 10,000 kilos of fat and protein.

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…

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.

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…
