  1. N it indicates the number of samples in each pig herd; The sample sizes of the LM and Me pig populations are small and do not have statistical significance, thus the pig herd for accuracies analysis of were excluded, LW Large White pigs, LL Landrace × Large White pigs, Su Suhuai pigs, PM Pietrain × Meishan pigs, DLL Duroc × (Landrace × Large White pigs).
