The productive response of piglets during the first stages of life depends essentially on nutrients derived from mother's milk. At weaning, the challenges inherent to the change of phase may compromise their performance, health, and intestinal integrity. In this context, the study investigated the action of the inclusion of 1% L-Gln and L-Glu in the diets on the productive performance, histological parameters and economic viability of piglets during lactation and after weaning. During lactation, 28 sows with their respective litters were distributed in a completely randomized design with two treatments (Control group: basal diet for gestation without supplementation; Supplemented group: basal diet with inclusion of 1% L-Gln and L-Glu). After weaning, a total of 288 piglets were distributed into two treatments (Control group: 144 piglets from lactation 1 receiving initial basal diet without supplementation; Supplemented group: 144 piglets from lactation 2 receiving basal diet with inclusion of 1% L-Gln and L-Glu). The inclusion of 1% L-Gln and L-Glu has demonstrated effectiveness in improving productive performance and preserving intestinal integrity in piglets during lactation and post-weaning, representing a relevant nutritional strategy in swine production. However, supplementation does not promote significant changes in blood concentrations of Gln and Glu in the animals.
