- Higher production
- Higher longevity
- Higher feed efficiency
With the best bulls for CRV Efficiency you will breed a herd that is more productive, has a higher longevity and a higher feed efficiency. The result is a higher efficiency and you also contribute to lower methane emissions.
A healthy herd makes work more pleasurable and profitable. CRV Efficiency helps you breed highly productive cows that convert feed efficiently into milk and achieve high lifetime production.
Index for efficiency
An efficient herd has a higher output in kilograms of milk or beef using a lower input of resources. That is better for profitability and for the environment. CRV’s indexes simplify breeding for health and efficiency.
Improvement of efficiency
Daughters of a bull with +6% CRV Efficiency will produce on average 3% more milk from their feed intake in their lifetimes. This implies additional lifetime production of more than 2000 kilos of milk. Traits included: milk, fat, protein, longevity, feed efficiency, calving interval, body weight.
In addition to production, longevity and feed efficiency, the CRV Efficiency index also includes persistency, late maturity, calving interval and age at calving.
Results breeding for efficiency
Practical research* shows that breeding for CRV Efficiency works. Cows with +6% for this index have a higher feed efficiency, higher lifetime production and higher longevity.
Important building blocks of efficiency
The CRV indexes give a complete picture of health and efficiency, but it is also possible to target the main components in the breeding strategy. Important building blocks of CRV Efficiency are production, feed efficiency and longevity. The table below shows the effect of breeding for the efficiency* building blocks.
* data based upon the Holstein breed and using a bull with a breeding value of >one standard deviation on an average cow (100)
** per 100 cows per year
An achievement we are proud of
Together with farmers all over the world, we work on producing healthy and efficient herds. We have been committed to this ambition for years. That is why we are the global leader in health and efficiency, which is an achievement we are proud of!
