The effect of levels of coenzyme Q10 on performance, carcass characteristics, some blood parameters, immune system, organoleptic properties of meat and gastrointestinal tract development of Japanese quails, was conducted using 605 one- day old Japanese quails in a completely randomized design with 11 treatments and 5 replicates from1 to 35 days of age. The experimental treatments included negative control, control, positive control and dietary levels of 15, 30, 45, 60, 75, 90, 105 and 210 mg/kg coenzyme Q10. The feed intake, feed conversion ratio and daily weight gain were measured in whole experimental period. The antibody titers against Newcastle and influenza vaccines and also sheep red blood cells were measured at 30 day of age. The feed conversion ratio was lower in treatment containing 210 mg/kg coenzyme Q10 than negative control treatment (P<0.01). The antibody titers against Newcastle and influenza and also SRBC were significantly increased as dietary level of coenzyme Q10 increased (P<0.01). The blood urea nitrogen concentration decreased by consumption of diets containing coenzyme Q10 than that of negative control treatment (P<0.01). The concentration of red and white blood cells and ileal crypts depth of quails fed diets containing coenzyme Q10 were higher than birds of negative control group (P<0.01). The meat redness and lightness showed improvement in quails fed diet containing 210 mg/kg of coenzyme Q10 in compared with birds of negative control treatment (P<0.01). Based on the results of this study, the addition of coenzyme Q10 up to the level of 210 mg/kg in the diet of Japanese quails improves the performance, blood parameters, immune system, and organoleptic properties of meat.

A total of 24 male and female Sanjabi suckling lambs with an average weight of 4.2 kg at birth day were used in a 90-day trial period using randomized complete block design for evaluation of two dietary antioxidants. The lambs were received forage and concentrate from the second week of birth in addition to maternal milk. The experimental diets included control (milk and starter), control + 10% lemon balm (Melissa officinalis) and control + one tablet CoQ10 (30 mg). Every 30 day of experiment blood samples were drawn from jugular vein to measure some hematological and enzymatic parameters. No significant difference was observed among treatments for daily milk, dry matter intake and performance of lambs. Hematocrit was not affected due to lemon balm but it was increased (P<0.05) by CoQ10. Diets containing antioxidants increased the total white blood cells compared to control (P<0.05); but monocytes and basophils did not alter these parameters. Lemon balm reduced the lymphocytes and increased neutrophils while CoQ10 did not influence these two parameters. Eosinophil in blood samples of lambs received Lemon balm or CoQ10 were more than that of control (P<0.05). The concentrations of glutathione peroxidase, immunoglobulin-G and total antioxidant capacity were not affected by treatments, but lemon balm supplementation decreased (P<0.05) malondialdehyde index. The results of this experiment showed, the use of lemon balm in 10% of diet as well as 30 mg/day of coQ10 in suckling lambs’ diet improved immune system, however no significant changes observed in the performance of the lambs.

This experiment was conducted to determine the effect of vitamin C (VC) and coenzyme Q10 (CoQ10) onimmunity response of broilers in cold stress condition using 500 male chicks in a completely randomizeddesign with 5 treatments and five replicates. Treatments were: positive control (PC, normal conditionsgrowth without antioxidants), negative control (NC, cold stress without antioxidants), cold stress + VC(300 mg/kg diet), cold stress + CoQ10 (40 mg/kg diet) and cold stress + VC + CoQ10 at above mentioneddoses. To induce cold stress, from day 15 until end, temperature fixed at 15oC. Vaccine titers, humeraland cellular immune response and relative immune organs weight were studied. Results showed that coldstress decreased relative spleen weight but there was no significant difference between treatments.Relative weight of bursa was increased in cold stress condition (P<0.01) and using antioxidant especiallyCoQ10 decreased it (P<0.05). Lymphocyte percent decreased in cold stress (P<0.05). Improved cellmediatedimmune response to subcutaneous injection of phytohemagglutinin and proliferation of Tlymphocyte in vitro were observed (P<0.05). In conclusion, use of antioxidants VC and CoQ10 in the coldstress condition improved immune system activity and decreased mortality
