The purpose of the conformation scoring is to form the basis for a breeding improvement of the cow's functionality and usability. Registrations from the Nordic Classification system are used as phenotypes in the breeding value calculations. The conformation scoring is done by breeding advisors.
Udder conformation index (27% of TMI)
The goal is for the udder to be easy to milk and work well in automatic milking systems. The udder should not inhibit the animal from moving and it should not have a conformation that easily causes damage and affects the udder health.
The udder conformation index consists of nine traits viewed from the exterior of the cow.
These udder traits are weighted in such a way that a high score for udder index reflects a durable and functional udder. Udder conformation traits are scored by breeding advisors using a linear scale.
The udder trait definitions are harmonized with definitions for dairy cattle populations in other countries.
Traits | Relative weight (%) |
Udder depth | 19.6 |
Front teat placement | 13.2 |
Rear teat placement | 15.3 |
Udder balance | 6.6 |
Fore udder attachment | 12.3 |
Rear udder width | 3.0 |
Rear udder height | 6.8 |
Udder cleft | 13.9 |
Teat length | 9.3 |
Feet and legs conformation index (3% of TMI)
The conformation traits registered are rear legs side view, rear legs rear view and foot angle.
Traits | Relative weight (%) |
Rear legs, side view | Not included |
Rear legs, rear view | 50 |
Foot angle | 50 |
Stature (Not included in TMI)
Stature is measured as rump height and stated in centimeters.
Body depth (Not included in TMI)
Body depth is measured as the length between the spine and the base of the posterior rib. It is measured on a scale from 1 to 9, where 1 is narrow and 9 is deep.
