Pigs adapt their feeding patterns to the level of feed restriction by modifying their feed intake in the early hours of the day (McSweeny et al, 2003). This observation led to the investigation of a new feeding-pattern trait, defined as the percentage of the total daily feed intake eaten between midnight and 0600 h (P6AM). This trait (μ=35%) is specific to the feeding system studied and may provide additional information for genetic improvement of performance traits. The aim of this experiment was to estimate genetic correlations between P6AM and economically important traits.
