This gallery has been put together to help farmers and vets identify genetic defects in cattle. It will always be a work in progress due to the fact that new diseases will always be identified. Hopefully this gallery can be used as a tool to report what is seen on a farm. Only through accurate reporting and sample collection will we be able to identify ways to decrease the incidence of these genetic defects and others.

If you would like to report a defect, please click on the link below to fill out the congenital defect survey:
