|Abstract:||1. This study was conducted to determine the effects of volatile oil mixture on quail laying performance, egg traits and egg malondialdehyde (MDA) concentration. 2. A total of 260 Pharaoh quails (Coturnix coturnix Pharaoh) aged 6 weeks were equally divided into 5 groups of 65 (4 replicates of 13 quails each). The mixture of diets was as follows: a control treatment with 0mg volatile oil/kg of diet; (1) 200mg/kg rosemary volatile oil; (2) 200mg/kg oregano volatile oil; (3) 40mg/kg rosemary volatile oil plus 160mg/kg oregano volatile oil (ratio 20:80) and (4) 160mg/kg rosemary volatile oil plus 40mg/kg oregano volatile oil (ratio 80:20). The diets were prepared fresh for each treatment. The experimental period lasted 10 weeks. 3. At the end of the experiment, there were no significant differences amongst the groups in body weight, egg weight, egg mass, egg shape index, Haugh unit, egg shell thickness or egg shellbreaking strength. 4. Diets containing rosemary volatile oil increased the egg production significantly. Feed intake significantly increased in the groups containing volatile oil mixture (groups 4 and 5). The inclusion of rosemary volatile oil at 200mg/kg improved feed efficiency. 5. Egg albumen and egg yolk index values showed significant increases in the group given diets containing rosemary volatile oil. Egg yolk colour became darker with the addition of rosemary and oregano volatile oil. The treatment group had lower egg yolk MDA concentration than the control group. 6. It is concluded that, alone or in combination, rosemary and oregano volatile oil can be used in quail diets without adverse effects on the measured parameters. Inclusion of rosemary and oregano volatile oil in quail diets enhanced the antioxidant status of eggs.|
