Abstract
This study shows the effectiveness of diet containing Trachyspermum copticum (TC), Majorana hortensis Minch (MH), Stachys lavandulifolia Vahl (SL), and Zingiber officinale (ZO) on the growth performance, biochemical factors, and qualitative agents of eggs of Japanese quail (Coturnix japonica) and their immune responses against Newcastle and Avian Influenza vaccine. For this prepose, 675 quails were divided into 9 groups with three replicates and fed with different treatment diets (basic diet with no supplements (control treatment diet) and diets supplemented with one of two levels (0.5 and 2%) of each plant powders). Data showed that the use of TC 2% increased the Haugh unit significantly (P < 0.05) compared with the control (P < 0.05). At the end of the experiment, shell weight (g) and shell thickness were also remarkably enhanced in treated groups compared with the control group. Moreover, the findings of this study showed the thiobarbituric acid and yolk cholesterol level reduced remarkably (P < 0.05) in the MH and SL groups without significant adverse effect on albumen protein (%) and total protein (%) level. In this study, TC-2%, ZO-2%, and SL-2% all increased the antibody titers against avian influenza. The use of a diet containing MH-2% increased Newcastle disease in Japanese quail in comparison to both controls and different levels of other medicinal herb powders. Based on these results, using these four herbal plant powders in Japanese quail, diets could positively affect their egg qualitative and biochemical factors.
