Cow and Heifer Genomics



Genomic testing is the process of analysing a heifer's DNA - such as in ear tissue or a tail hair - to reliably predict her future performance in the herd.

Genomics can be conducted as early as birth, so farmers can make informed decisions about a heifer’s role in their herd. DNA samples are easy to collect and can be taken at the same time as routine husbandry procedures, such as ear tagging or disbudding.
