Breeding for feed efficiency has no effect on conformation traits or health.
CRV has the largest reference population with actual feed intake data of dairy cows (7008 cows). Viking does not yet use actual feed intake data when calculating feed efficiency, whereas ST Genetics/Cogent uses feed intake data from young stock (4000 cows). They convert the feed intake for growth into the feed intake for milk production. Literature suggests there is a correlation between this data, but it is clearly less strong than the feed intake measured in lactating animals.
What does feed intake comprise?
The feed intake as measured and expressed by CRV is the feed intake during lactation. The feed intake during rearing is excluded. However, this is included in the CRV Efficiency index. Feed for rearing (body weight and age at 1st calving). Feed for maintenance (body weight). Feed for milk production: goal ‘more milk per kg feed’.
CRV has locations all over the world, divided into business units per region, and a global distribution network. CRV works with enthusiastic employees who know the customers and their desires.
