Breeding

These are the groups at the NRM 2019

CRV will show three progeny groups and two theme groups at NRM 2019. These groups show that we stand for efficient and healthy herds with high components. Read more information below about the Fun P, Bouw Finder and Bouw Rocky progeny groups and the Delta Satellite and “Proven cows with high components” theme groups.
DELTA FUN P
We will show a group of second calvers and heifers from the red-and-white bull Delta Fun P. The Fun P daughters are very productive and can easily cope with their high production, which makes them very efficient. Fun P is currently the highes…

‘A high protein content is no coincidence.’

The sky-high components of InSire Top Bull De Leenhorst E-Profit do not come out of nowhere. The dam line behind the bull is responsible for high protein contents, generation after generation.

“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 cows…

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.
