Breeding for climate smart cows

Published: 04 July 2013

A DNA sample that can be taken at birth provides important information about the breeding value of an aspiring dairy cow or breeding bull. Breeding programmes with genomic selection may also make it possible to introduce new traits in the breeding process, as feed conversion and emissions of greenhouse gases. This is told by Helen Hansen Axelsson in a doctoral thesis from SLU.

– Taken together, my computer simulations show that breeding programmes with genomic selection could be used to reduce the environmental impact of milk production, without significant deterioration of milk production and the durability of cows, says Helen Hansen Axelsson.
