چکیده	A total of 720 one-day-old Arian broiler chicks were used to determination of effects of different feed formulation patterns on productive and immune responses. Birds were randomly allocated to 4 group with 6 replicates containing 30 bird (15 males + 15 females). Measurements were subjected to analysis of variance for completely randomized 2×2 factorial design that including 2 dietary energy expression patterns (Apparent (AMEn) and true (TMEn) metabolizable energy corrected to nitrogen equilibrium) and 2 amino acid requirement patterns (Total (TAA) and digestible (DAA)). The results showed that when the feed formulation was based on TMEn and, the productive parameters increased compared with AMEn (p<0.05). However the most suitable of immune responses were belonging to treatments were fed diets which were set based on AMEn and DAA. There is a negative correlation between immune responses and productive parameters. It is recommended that in normal conditions use of TMEn and DAA system and in stress conditions use of AMEn and DAA to feed formulation.
