Abstract
Abstract A study was conducted to investigate the effect of optimizing valine-to-lysine ratio by dietary supplement with valine (Val) in late gestation (starting on day 85) or lactation on biochemical indices and lactation performance. Sixty pregnant gilts (Yorkshire × Landrace) were randomly allocated to one of four treatments in a 2 × 2 factorial experimental design, where the factors were supplementation with L-Val (optimizing total valine: lysine to 0.87:1) or with L-alanine (Ala, isonitrogenous control) in late gestation and/or lactation. The diets contained 14.02 MJ of ME/kg energy and 203.1 g/kg to 203.3 g/kg crude protein (CP), were fed at 2 kg daily during late gestation and ad libitum during lactation. Feeding the Val-supplemented diet compared with control during late gestation improved the weaning body weight (BW) and of sucking piglets (P
