  1. Results were presented as mean values with their standard errors, n = 10. LV: total valine: lysine = 0.63: 1; MV: total valine: lysine = 0.73: 1; HV: total valine: lysine = 0.93: 1. * adjust: within 24 h of farrowing, the litter size was standardized to 10 piglets per gilt, depending on their availability and bodyweight, by cross fostering the piglets within the same treatment. Means not sharing the same letter are different (P < 0.05)
