Description of the test at The National Test Station
The purpose of the test of bull calves at The National Test Station is to achieve knowledge about the genetic value of the bull regarding growth, feed efficiency and muscularity.
Moreover the exterior is evaluated by the linear method and the staff at the test station documents the docility of the bull a number of times during the test period.
The test of each bull is performed at The National Test Station in Aalestrup.
The test periode is 5 month – from 225 days to 365 days of age.
Free access to feed
- Weigth everly 28th day
- Feed consumption during the testperiode
- The area of the big muscle in the back are measured 3 times, when the bull is 10, 11 and 12 month old
Docility is evaluated 11 times during the test periode.
Calculation of the genetic value of the bull through indices (average 100):
- Growth, T-index
- Muscularity through ultrasound measurements, U-index
- Feed efficiency, FEF-index
The bull are exterior evaluated by the linear method at the end of the test, Conformation index.
Data from the test at The National Test Station is used when all the indices of the bull is re-calculated.
