A total of 184 Large White pigs were used to compare performance in pens with electronic feeders (ad lib feeding) with performance in commercial pens (restrictive feeding). The animals were allocated to the two treatments by using split-litter technique. Correlations between performance in the two systems were calculated. The correlation was high for lean percentage (0.81), but lower for LTGR (0.66) and growth rate (0.53).
