  1. DLY-P1, DLY-P2, DLY-P3 the first, second and third cohorts of Duroc × (Landrace × Yorkshire) hybrid pigs
  2. DLYall the combination of all three DLY cohorts
  3. CL carcass length, BL live body length; LTV_10th, LTV_mean, and LTV_all represent the length of the 10th thoracic vertebra, the average length of thoracic vertebrae and the total length of all thoracic vertebrae, respectively, NTV number of thoracic vertebrae, LLV_all total length of all lumbar vertebrae
  4. N number of animals measured, sd standard deviation
