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 %> http://jstnar.iut.ac.ir/article-1-374-en.pdf %P 185-195 %& 185 %! %9 Research %L A-10-2-374 %+ %G eng %@ 2476-3594 %[ 2005
