Difficulty in gathering relevant large-scale data in routine
• Small sized cattle populations
• (Organic) pasture based production systems

Novel MIR predicted milk traits for dual-purpose cattle:
heritable selection
promising early indicators of longevity (for dpBB)
Use of genomics:
Slight increase of reliabilities (not shown)
GEBV for novel MIR traits tend to be better predictors of longevity
