A total of 160 Lehman Brown layer 45 weeks dy completely randomized with five replicates (cages in battery system) each replicates contain of four birds and the period of this experiment was 112 days, The nutritional treatments were , T1: basal diet (control) contained 16.32% cruds protein (C.P) with 0.41% synthetic methionine (S.Thrionine) , T2: basal diet (16.32% C.P) with (0.41%) herbal methionine (H.M) and (0.106% S.Thironine) . T3 : basal diet (16.18%C.P) with (0.42%S.Mthionine ), (0.05% herbal lysine :H.L) and (0.106% S.Thrionine) T4: basal diet (16.18% C.P) with (0.42% H.methionine), (0.05%H.Lysine) and (0.106% S.Thrionine) , T5: basal diet (15.45%C.P) with ( o.42% S .methionine) , 0.12% S.Lysine ) and (0.116% S.thronine ) T6: basal diet (15.46% C.P) with (0.42% H.methionine),(0.045% H.Lysine) and S. threonine ), T7: basal diet (15.12%C.P) With (0.148% S.methionine , (0.150% S.lysine ) and (0.130% S.thrionine ) ,T8: basal diet (15.12%C.P) with (0.148% H.methionine ) , (0.150%H.lysine) and (0.130% S.thrionine , The experiment showed that there were no differences in egg production and egg mass between treatments, while significant differences were found in egg weight between treatments. , While no differences appeared between the treatments for the characteristic of shell thickness, specific weight of shell, and egg shape index, nor did significant differences appear in the biochemical properties of blood serum..
