Composição de aminoácidos da carcaça do pintado (pseudoplatystoma corruscans) baseada no conceito de proteína idealAmino acids composition of the carcass of pintado fish (Pseudoplatystoma corruscans) based on the concept of ideal protein. Zootecnia Trop. [online]. 2003, vol.21, n.2, pp.109-117. ISSN 0798-7269.

The amino acids composition of the muscle tissue of pintado (Pseudoplatystoma corruscans) was determined with basis on the ideal protein concept. Ten fishes with initial weight of 2.58 ± 0.52 kg were used for analysis. The AAE/L ratios [(each essential amino acid content including cystine and tyrosine/lysine) x 100], of 29.58, 42.35, 33.50, 11.25, 68.02, 23.89, 42.73, 49.81, 43.36, 76.86 e 52.47%, for methionine, methionine + cystine, threonine, thriptophan, arginine, histidine, isoleucine, leucinae phenylalanine, phenylalanine + tyrosine, and valine, of muscle tissue, respectively, suggest that the amino acid requirements of "pintado" are not greatly different among species. The AAE/L ratio will provide valuable index for supplemental amino acids in diets for "pintado".
