The 2 experiments were conducted using 21 ± 2 d old pigs that were the offspring of Line 359 males mated to C-46 females (PIC, Hendersonville, TN). In each experiment, pigs were weaned in 2 groups at 2-wk intervals and placed in 2 environmentally controlled and ventilated nursery rooms; 1 with 32 pens and the other with 40 pens. Each pen in both rooms was 1.2 × 1.4 m with slatted floors, and each pen was equipped with a single sided feeder and a nipple drinker. Pigs in both experiments were identified by ear tags, and within each weaning group, pigs were allotted to pens by initial BW groups. Sex within pens was balanced within each replicate. Dietary treatments were randomly assigned to pens within weaning group and initial BW groups. Pigs were provided ad libitum access to feed and water throughout both experiments.
