  1. 1 For each source, G2 progeny were derived from G1 boars. All pigs tested for immune traits also had performance measurements. 2642 pigs were performance tested, 1280 pigs were tested for immune traits and 920 pigs were tested for APP. 2 All sires were measured when they were growing pigs. 3These were the same sires.
