This experiment was conducted to assess the effects of using medical plant Thyme (Thymus) and pennyroyal leaves on hematological indices(hematocrit, hemoglobin, red blood cell, total white blood cell, heterophil, acidophil, monocyte and basophil) of Japanesequails. The birds were divided in to three groups (each group had four replicate and each replicate had 13 female quail); group1: control without medicinal plants supplementation, group2: include pennyroyal (0.75% of total ration), and group3: include Thyme (0.75% of total ration).the experimental period was 5 weeks and all of them have same age (42 day) and they were at the onset of egg production period. Their dietary treatments on basal corn and soybean meal that medical plants (Pennyroyal and Thyme) used on 0 and 0.75 levels. With exception to decreases in heterophil number for group three (fed thyme leaves), there was no any considerable changes for hematological indices. As conclusion, supplementation of thyme or pennyroyal leaves cannot cause any negative effect on hematopoiesis or leukocyte differential numbers in Japanese quail.
