Objectives: The purpose of this study was to determine the effect ofaddingfenugreek (Trigonellafoenum L.) and Savory (Saturejahortensis L.) powder individually or in combination on the performance. biochemical and immunity parameters in White Leghorn layer (Hy-line W36) after forced molting. Materials & Methods: The experimental design was completely randomized repeated mesurement analysis including: Group 1: receiving the basal diet (without addition of any medicinal plants). Group2: receiving the basal diet with 1% fenugreek powder, three: receiving the basal diet with 1% Savory powder, fourth experimental group: basal diet with Fenugreek powder and Savory powder which was 0.5 percent. This study was design and carried out 128 white leghom layer (Hy-line W36) at the age of 75 weeks and after molting, with 4 treatments, 8 replicates and 4 observationsper replicate, after 2 weeks' primary adjustment. in three periods (total period of treatment 63 days). Results & Conclusion: The results showed that in treatment group receiving the combination of 0.5 percent Savory and 0.5 percent Fenugreek powder feed intake (FI) was reduced significantly (P>0/05) and in groupl (receiving basal diet) the feed intake in third period wasincreased, significantly (P>0105). The maximum percentage of egg production in the third period as compared to the first period increased significantly (P>0105). In treatment group receiving the combination of 0.5 percent Savory and 0.5 percent Fenugreek powder, egg specific gravity and shell weight parameters increased significantly compared to control groups (P>0/05). Cholesterol was reduced significantly in groups 2 and 4 compared to other groups (P>0/05).
