Abstract: Thirty-six broiler chickens (COBB comercial line) four-week old were used to assess the apparent ileal digestibility of protein and amino acids with the dietary inclusion of mucuna (Mucuna deeringiana) foliage meal. The animals were distributed according to a completely randomized design with 4 treatments and 3 replicates: control (maize-soybean) and 3 dietary mucuna foliage meal levels of inclusion: 50, 100 and 150 g kg 1. The apparent ileal digestibility of Crude Protein (CP) and 14 amino acids was determined.The protein digestibility was lower (p<0.05) in both 50 and 150 g kg 1 of mucuna inclusion than in the control diet. The coefficients of apparent ileal digestibility of amino acids in birds fed 150 g kg 1 mucuna foliage meal were lower (p<0.05) than in those fed the control diet. It is outstanding that there were low apparent ileal digestibilities of glycine, tyrosine and proline with 50 g kg 1 of mucuna inclusion in diets. No differences were observed between the control and 100g kg 1 mucuna inclusion diets for amino acid digestibilities except for lysine, aspartic acid and valine. It was discussed the role of the dietary fibre content and the presence of anti-nutrient factors as responsible of findings. It is concluded that dietary inclusion up to 100 g kg 1 mucuna foliage meal did not affect apparent ileal digestibility of most amino acids studied in the current research.
