Evaluation of Muscle Chemical and Amino Acids Composition in Broiler Chicks Fed Sorghum or Sorghum-Pea Diets

ABSTRACT The study evaluated the chemical and amino acids (AA) composition of breast and thigh muscle in broilers fed sorghum and sorghum-pea diets, as partial substitute of corn and soybean meal (SBM). A total of 540 3-wk-old broilers (Cobb 500) randomly assigned to three groups were fed with corn-SBM control diet (C), corn-sorghum-SBM diet (S) and corn-sorghum-peas-SBM diet (SP) for finisher phase. At slaughter, muscle samples were collected for chemical analyses. The results showed that dietary sorghum or sorghum-pea inclusion did not affect (p>0.05) the chemical composition (dry matter, protein, fat and ash) of broilers muscle tissue. The total AA (TAA), essential AA (EAA) or flavour-related AA (FAA) concentrations from breast or thigh muscle did not differ (p>0.05) between treatments. A significant effect (p
