Abstract
This work aimed to investigate the effects of dietary frankincense oil and ginger on the growth efficiency of growing Japanese quail, including live body weight, body weight gain, feed intake, feed conversion ratio, carcass traits, and physical characteristics of the meat. In total, 150 unsexed Japanese quail chicks that were 7 d old were utilized in the experiment. The chicks were randomly divided into 5 groups. Each group was divided into 3 replicates with ten birds in a completely randomized design. Group 1 received a basal diet without supplements and was used as a control group. Groups 2 and 3 received basal diets with 250 and 500 mg of ginger per kg of diet, respectively. Groups 4 and 5 received basal diets with 200 and 400 mg of frankincense oil per kg of diet, respectively. Results showed that BW of chicks received 500 mg of ginger and the 2 levels of frankincense oil at 5 wk of age, and 250 mg of ginger and 400 mg of frankincense oil at 6 wk significantly increased. BWG was significantly increased by using 500 mg of ginger and 2 levels of frankincense oil at 1 to 3 wk, 250 mg of ginger and 400 mg of frankincense oil at 3 to 6 wk, and 1 to 6 wk of age, in comparison with the control group. Treatments insignificantly influenced feed intake (FI), and feed conversion ratio (FCR) was improved considerably by using 250 mg of ginger and 400 mg of frankincense at 3 to 6 wk and 1 to 6 wk of age, respectively. Gizzard% was notably reduced with 200 mg of frankincense oil. The pH value of meat was significantly increased by having 2 levels of ginger. Still, water holding capacity and tenderness significantly decreased owing to 500 mg of ginger and 400 mg of frankincense oil. We can conclude that adding ginger and frankincense oil to Japanese quail diets may be beneficial.
