¹A total of 2,808 pigs (Line 337 × 1050; PIC) were used in a 28-d study. Pigs were weaned at approximately 22 d. On entry into the nursery, pigs were randomly sorted into 1 of 104 pens (52 pens of barrows, 52 pens of gilts), with one pen of gilts and one pen of barrows per fence line feeder. Pigs were blocked by BW and then randomly assigned to one of four dietary treatments in a completely randomized block design with 13 feeders per treatment. Experimental diets were fed from days 0 to 28.
