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.

Effect of adding Melissa officinalis aqueous extract was studied on immune response and performance in 200 Ross 308 broiler chicks in a completely randomized design with five treatments and four replicates and 10 observations per replicate. The amounts of 0 (control), 0.5, 1, 1.5 and 2 ml/L Lemon balm extract were added in drinking water for 42 days. Humoral immunity was evaluated by injection of 0.1 ml sheep red blood cell (SRBC) 25 percent on days eight and 22 of age and measurement of serum antibody levels produced in response to SRBC on days 21, 28, 35 and 42. Cellular immunity was assessed by injection of phytohemagglutinin intradermally on day 16. The consumption of Lemon balm extract had no effect on daily feed intake and daily body weight gain (P>0.05). The birds that received 1.5 and 2 ml Lemon balm extract in drinking water had lower feed conversion ratio in grower and whole period (P<0.05). The birds that received Lemon balm aqueous extract in drinking water had higher total Anti-SRBC titer than control birds on days 28, 35 and 42 (P<0.05). IgG titer of birds that received Lemon balm extract was higher than control group on day 28 (P<0.05). IgM titer of birds that received 1, 1.5 and 2 ml of Lemon balm extract was higher on days 28 and 35 (P<0.05). It is concluded that inclusion of 1.5 ml Lemon balm extract in drinking water decreased feed conversion ratio and improved humoral immunity in broilers.
