As usual, the index run for December does not have many surprises. Genetic progress remains the spearhead and a consistent breeding strategy delivers results. This applies to ‘rich milk’, but equally to health and efficiency and consequently longevity. After this index run, CRV will continue offering its members and customers a highly interesting portfolio of bulls. So that farmers can look to the future with the full confidence of a healthy and efficient herd.

Bouw Rocky the undisputed number one for longevity

The names of three familiar and reliable bulls, Bouw Rocky, Delta Fun P and Delta Bookem Danno, still rank high among the daughter-proven sires. With an NVI of 302, Danno is the highest ranked, daughter-proven bull in the Netherlands and Flanders. Danno daughters achieve high production, offer outstanding legs and are persistent performers (longevity 612 days).

At the HHH-show, CRV shows a group of daughters by the polled, red-and-white Fun P. His offspring all score high for longevity (555 days), production (€ 334 Inet) and are highly balanced, good dairy types and exceedingly attractive (aAa 153624). If your dream is a queen of the show ring, you can’t afford to overlook Fun P.

With more than 100 daughters on their third, or more, lactation Bouw Rocky tops the list as the undisputed number one for longevity (1149 days). His daughters are very well balanced, strong and show good dairy type (aAa 351426).

Breeding for ‘rich milk’

A consistent breeding strategy focussed on components delivers results. As a farmer, you want to breed healthy, easy to manage cows that produce component-rich milk. Higher percentages of components not only have an immediate positive effect on the milk price, higher efficiency is another indirect effect. A newcomer to the index is Magister son De Leenhorst E-Profit. E-Profit certainly does his name justice and delivers profits with a capital P in the form of phenomenal component transmission (+0.52% fat and +0.40% protein) combined with super milk production (921 kg), faultless linear traits and without exception positive health and fertility traits.

In the shape of Delta Builder P CRV also offers a heterozygote polled bull who passes on impressive milk production (1.306 kg) and outstanding components (+0.31% fat and +0.18% protein).

Horst Libero is the standard bearer for the red-and-white team. He offers qualities in abundance with excellent conformation (108) partnered with good components (+0.52% fat and +0.11% protein) and very decent milk production. These are bulls with a strong appeal for farmers thanks to their efficient production.

Delta Jacuzzi-Red extreme efficiency

Delta Jacuzzi-Red still tops the charts for the red-and-white segment. His daughters are extremely efficient (19% Better Life Efficiency) and have sterling udders and legs. In July 2017, CRV – as the first AI organisation in the world – started to collect feed intake data on normal, commercial dairy farms. Starting with the index run for December, CRV will include this feed intake data in the breeding value estimation.

Heading the list for the black-and-white segment, Delta Bonjour also gives great scores for efficiency (13%) and stands out for his wonderful health traits. And in terms of efficiency (12%) the red-and-white, homozygote, polled bull Delta Elixer-Red certainly matches up to the competition. Elixer’s daughters will also inherit super udders and legs. Whether your focus as a dairy farmer is on boosting the components, polled cows or feed efficiency, CRV presents another wide range of bulls that match your breeding goals.
