Amino acid digestibility and energy use by weaned piglets fed yellow corn, sorghum and an exogenous enzymes combination

•The use of the enzymes isolated or the enzyme combination no have effects on the nutrients digestibility, energy use and amino acids in yellow corn.•The enzymes combination no have effects on the protein digestibility, energy use and amino acids in sorghum.•Multicarbohydrase improves the dry matter digestibility in sorghum.
