Three hundred and sixty day-old Arian male broiler breeder chicks were used in a 2×3 factorial experiment with two levels of metabolizable energy (3050 and 3200 Kcal/Kg) and three levels of protein and sulfur amino acids (110% NRC, NRC and 90% NRC) in a completely randomized design with four replicates per treatment. Results obtained from the whole of the experiment’s period (0-49 days of age) indicated that level of dietary energy had a significant effect on body weight and daily gain (P CP - IRAN IN - LG - eng PB - JSTNAR PG - 185 PT - Research YR - 2005
