Diplotype	TNB*	NBA*	Number of weaned piglets*	TNB**	NBA**	Number of weaned piglets**
Hap1/1 (17)	10.06 ± 1.64a	9.76 ± 1.39	9.71 ± 1.31a	9.82 ± 1.07	9.71 ± 0.92	9.65 ± 0.93
Hap1/2 (24)	9.17 ± 1.27b	9.04 ± 1.20	8.88 ± 1.12b	9.71 ± 1.49	9.46 ± 1.53	9.04 ± 1.04
Hap1/3 (26)	9.77 ± 1.18a	9.65 ± 1.02	9.35 ± 0.94a	9.85 ± 1.43	9.65 ± 1.44	9.46 ± 1.27

Hap1/1, TTAAGGAAAATT; Hap1/2, TTGAGGAAAATT; and Hap1/3, TCGAGGAGAGTA. Different lowercase letters indicate significant differences (p < 0.05), same small letter differences are not significant (p > 0.05). TNB is the number of births, NBA is the number of live births. ^*Indicates first litter performance per sow; ^**indicates the litter performance of the second litter per sow.
