The improvement growth performance, carcass and quality traits of F1 IGF2C/T generations. A The average birth weight of IGF2C/T piglets were heavier than WT piglets regardless of genders (WT: n = 26; ED: n = 20). B Both male (M) and female (F) IGF2C/T pigs have a better body weight gain than WT controls starting from 6 until 11 months of age. C Representative photos of WT and IGF2C/T pigs at 5 months old. D and E mRNA and protein expression of IGF2 and ZBED6 in longissimus lumborum muscle of 7, 270 and 370-day-old female pigs. n = 3 per group. F Both male (M) and female (F) IGF2C/T pigs had a better performance on carcass traits (lean mass, loin muscle area, backfat thickness), meat quality traits (marbling, meat color) and heart weight than the WT pigs of 270-day-old and 370-day-old. Each black point represented actual data (270 d M: WT, n = 3; ED, n = 5; 270 d F: WT, n = 3; ED, n = 4; 370 d M&F: n = 4 per group). All data were presented as mean ± SEM. *P < 0.05, **P < 0.01, student's t-test
