Data are presented on the chemical composition of chaya leaf meal (CLM) ( Cnidoscolus aconitifolius (Mill.) Johnston) and the availability of its amino acids to chicks. The crude protein, fat, ash, curde fibre and metabolizable energy contents were 296.2 g kg −1 dry matter (DM), 40.7 g kg −1 DM, 139.5 g kg −1 DM, 101.3 g kg −1 DM and 8.88 MJ kg −1 DM, respectively. CLM was relatively high in its content of calcium and iron. The sample contained anti-nutritional factors such as hydrocyanic acid and oxalate. No anti-tryptic activity was however detected in CLM. The amino acid composition of CLM indicates it is a good source of lysine and a fair source of sulphur-containing amino acids, cystine and methionine. The overall amino acid availability was moderately high (84.0%). With the exception of methionine and cystine, the amino acids in CLM had availability values > 80% and could therefore be regarded as moderately highly available.
