CRV introduces breeding value feed efficiency

category Breeding, Genetics

In December, CRV is introducing a new breeding value for its own bulls, which will enable a targeted and direct way to breed for feed efficiency. The index indicates how much more milk is produced by daughters of a particular bull using a kilogram of dry matter feed intake, compared with the population average. Good feed efficiency also means more efficient use of nitrogen and other minerals and a lower CO2 footprint for the production of milk.
