Genetic gain on body composition in pigs by Computed Tomography (CT). Return on investment (invited talk)
1. Genetic gain on
body composition in
pigs by Computed
Tomography (CT).
Return on
investment

2. Accurate and non-invasive
in vivo measurements
Backward compatible
Increase of genetic gain is
around 30%
Value for industry
3. Hazel, L. N. (1943). The Genetic Basis for Constructing Selection Indexes.
1. The selection differential
2. The multiple correlation between aggregate breeding
value and the selection index
3. Genetic variability
Without data, you are blind and deaf

19. The scientific conclusions
3500 boars are tested and scanned annually from 2008
Focus on body composition
An estimated increased genetic gain of 30%
Meat quality are under development.
Leg weakness scoring (osteochondrosis) has been implemented
Backward compatibility
The next steps
Automatic script for osteochondrosis
Weight of cuts
Meat quality
Integration with ultrasound and vision systems
Development of new protocols (kV, mA, dual-scan)
