This study was conducted to determine the effects of low-protein diets supplemented with crystalline amino acids (AA) on biochemical parameters and performance in 10 crossbred piglets weaned at 28 days of age ( 2 groups of 5 each, 8.8±0.6 kg and 8.6±0.7 kg live weight). The treatments were a control diet containing 210.8 g.kg -1CP (crude protein) and low protein diet containing 186.4g.kg-1 supplemented with crystalline AA (lysine, threonine, methionine) to achieve an ideal AA pattern. Blood from all piglets was taken for determining biochemical parameters 5 weeks after weaning. The decrease in the diet CP content was manifested signification P< 0,01 decrease concentrations of blood urea (average concentrations 2.61 mmol.l-1 and 4.21 mmol.l-1), which means the increase of biological value in the feed mixture.
