The current study was conducted to investigate the effects of dietary supplements of organic acid and essential oil Gallant on the growth hormone, glutathione, performance of growth, some biochemical parameters and intestinal histomorphology in quails. Japanese quails one-day-old (n=120) were distributed randomly into four groups included 10 / 3 replicates for each group. The G1, was control group that was fed on a basal diet. Quails of G2, G3, and G4 were fed on a supplemented diet Gallant 300, 600 and 900g/ton,respectively. Administration of Gallant 600 g/ton and 900g/ton to quail led to significant decrease in triglyceride while supplementation with 600 g/ton caused decrease in cholesterol. On the other hand, 300 g/ton caused an increase in final body weight and total weight through the duration of the experiment, as well as a decrease in total feed consumption and the best feed conversion ratio in all supplementation with 300 g/ton caused a significant growth hormone elevation. All feed additives didn't affect the level of glutathione. The addition of Gallant additive groups. Interestingly, the addition of different doses of Gallant to the diet increased villus length and width, crypt depth, villus / crypt ratio, percentage of goblet cell, apparent surface area, and intestinal epithelium thickness compared to the control group. It was concluded that dietary supplementation with different doses of Gallant improved growth hormone, growth performance and intestinal histomorphology in Japanese quails, and dietary supplementation with organic acid and essential oil as alternatives to the growth promoter of antibiotics.
