Map of QTL1,2 on chromosomes 1–15 and chromosome Z. 1Results from Tran et al. [9]; FIX_Y, FIDMX_Y: raw and dry matter feed intake between X and Y days; FCRX_Y, FCRDMX_Y: raw and dry matter feed conversion ratio between X and Y days; FEW, DEW: fresh and dry excreta weight between 17 and 20 days; FEW/FI, DEW/FI: fresh and dry excreta weight relative to feed intake between 17 and 20 days; WC: water content of excreta, N/P: nitrogen to phosphorus ratio in excreta; DUW, JEW, ILW, INW1: duodenum, jejunum, ileum, and small intestine weight at 23 days; DUW/BW, JEW/BW, ILW/BW, INW/BW1: duodenum, jejunum, ileum, and small intestine weight relative to body weight at 23 days; DUW/FI, JEW/FI, ILW/FI, INW/FI: duodenum, jejunum, ileum, and small intestine weight at 23 days relative to feed intake between 9 and 23 days; DUL, JEL, ILL, INL1: duodenum, jejunum, ileum, and small intestine length at 23 days; DUL/BW, JEL/BW, ILL/BW, INL/BW1: duodenum, jejunum, ileum, and small intestine length relative to body weight at 23 days; DUL/FI, JEL/FI, ILL/FI, INL/FI: duodenum, jejunum, ileum, and small intestine length at 23 days relative to feed intake between 9 and 23 days; DUD, JED, ILD, IND1: duodenum, jejunum, ileum, and small intestine density at 23 days; PHE, PHG, PHJ: pH of excreta, gizzard and jejunum contents; BWX1: body weight at X days; AMEn1: metabolizable energy corrected to zero nitrogen retention; CDUDM1, CDUP1, CDUS1: coefficients of digestive use of dry matter, protein and starch; PRW/BW1, GW/BW1, PRWGW/BW1: proventriculus, gizzard and proventriculus plus gizzard weights relative to body weight. 2Feed intake (dark red), feed efficiency (dark green), residual feed intake (olive green), excretion traits (orange), digestive efficiency (black), body weight (blue, light grey), breast and fat yields (pink) and anatomy of the digestive tract (purple, dark grey)
