Effect of Thyme's Crushed Leaves (Thymus vulgaris) on The Antioxidant Status of Quail

عبدالله فتحي عبدالمجيد


This study was conducted to investigate the effect of thyme's crushed leaves (Thymus vulgaris) on some biochemical parameters and the status of antioxidants in blood serum of quail. A total of ninety six female quail (Coturnix coturnix) in 49 days old were randomly distributed into 4 groups (24 birds/group) with 4 replicates/ group, and the treatments continued till the age of 91 days as follows: 1st group (control group): reared on the standard ration without of thyme, and the 2nd, 3rd and 4th groups reared on the standard ration supplemented with 500, 1000 and 1500 mg of thyme's crushed leaves / kg ration respectively. Ration and water offered ad libitum along duration the study.
Dietary supplementation of quail with thyme's crushed leaves showed a significant (p<0.05) decreasing effect on each of serum glucose, cholesterol and triglycerides concentrations, as well as a significant (P≤0.05) decrease in serum levels of Alanine transaminase (ALT) and Aspartate transaminase (AST) in treated quail with thyme as compared with control group. Also, the results showed no significant differences (P≤0.05) between the groups in each of serum total protein and uric acid concentrations.
On the other hand, The results of the current study showed that the dietary supplementation with substance possess antioxidant capacity as Thymus vulgaris (500, 1000 and 1500 mg of thyme / kg ration) had enhanced the antioxidants status in the blood serum, represented by a significant elevation in the level of glutathione (GSH) and a significant declining in the level of malondialdehyde (MDA) in treated quail with thyme compared with control group (P≤0.05).
