The growth in the broiler segment is expected to remain strong due to consumer preference for chicken meat. The live market sales of broiler meat still constitute more than 90 % of total sales volume as most consumers prefer freshly slaughtered chicken meat. Modern commercial broilers have a high capacity for lipid biosynthesis because selection strategies have focused on improved body weight gain, breast yield and feed efficiency. Therefore, finding new means to increase the skeletal muscle growth and to reduce excess fat is important for both human health and poultry production. A new horizon of study towards supplementation with L- arginine is effective for skeletal muscle growth. A total of 150 day old Cobb 400 broiler chicks were randomly allocated to 5 treatment groups viz., T1 (100 % of arginine requirement), T2 (125 % arginine), T3 (175 % arginine), T4 (125 % arginine for finisher period only) and T5 (175 % arginine for finisher period only). The aim of this study was to evaluate the effect of higher dietary Arginine supplementation on chemical composition of the breast muscle in broilers and was analyzed on dry matter basis by AOAC standard guidelines. The crude protein content of breast muscle was significantly higher in groups fed with excess arginine from day old to slaughter (T2 and T3). On the other hand, the fat content of breast muscle was significantly higher only in birds fed 175 % arginine in both starter and finisher period (T3) than control and was comparable with T2, T4 and T5 treatment groups. Dietary arginine at 75 % more arginine supplementation from the starter phase is recommended for highest intra muscular fat percentage
