This experiment was conducted to investigate the effects of some nutritional herbal plants powder on growth performance, Biochemical factors and Qualitative agent in Japanese quail eggs. These plants include: Trachyspermum copticum, Majorana hortensis Minch, Stachys lavandulifolia Vahl and Zingiber officinale that the major compounds of their essential oils were identified using gas chromatography-mass spectrometry. A total of 675 one day old Japanese quail, were randomly distributed in 9 groups by three replicate (25 birds (7 male and 18 female) in each replicate). Treatments were included two levels (0.5 and 2%) of each herbal plants powder and a control group with diets free of plants medicine. The results showed that the eggs weight (g), week eggs production and feed conversion ratio were affected significantly (p<0.05) by different level of herbal plants. According to the results, use of these four herbal plants powder in Japanese quail ratio could improve egg sensory properties and biochemical factors.
