The objective of the study was to determine the amino acid profile in protein from long bones of the pelvic limb (femur, tibiotarsus) in ROSS 308 hybrid broiler chickens, and to examine whether it is sex-dependent. The study material was obtained from 120 Ross 308 broiler chickens (60 males and 60 females) at the end of the fattening period (40 days of age). The average weight of birds was 2,694+/-32.6 g for cockerels and 2,345+/-23.9 g for pullets. The long bones of the right pelvic limbs (femur and tibiotarsus) were collected after bird slaughter. Crude protein contents and amino acid (AA) compositions were determined. The obtained values were recalculated to 100% dry matter. The chemical score (CS) and the essential amino acid index (EAAI) were calculated for each AA. Hen egg ovalbumin was used as a standard. The concentration of crude protein was significantly higher in the femur (405.3+/-17.21 g/kg) than in the tibiotarsus (393.5+/-12.68 g/kg). The same trends were found with regard to sex. Both males and females had significantly higher crude protein concentrations in the femur (406.6+/-19.34 g/kg and 404.1+/-15.09 g/kg, respectively) than in the tibiotarsus (395.0+/-12.16 g/kg and 392.1+/-13.21 g/kg, respectively). Both bones showed the highest concentrations of Gly, Glu and Pro, and the lowest concentrations of Met, Tyr and His. The same trends were found with regard to chicken sex. Collagenous protein has lower contents of most AA in comparison with ovalbumin. The collagenous protein EAAI for the femur and the tibiotarsus was 59.0% and 57.4%, respectively.
