In order to determine the effects of adding different levels of Satureja khuzistanica essential oilin two conventional and microcapsulated forms into the diet on performance, immune response, blood biochemical parameters and intestinal morphology of broiler chickens, an exprement was conducted using 400 Ross 308 (mixed sex) broiler chickens, in five treatments, four replicates and 20 chickens per each replicate. The expriment was done in a completely randomized design. Treatments included control (no additive), dietary containing levels of 400 and 500 mg/kg Satureja essential oil and dietary containing levels of 0.5 and 1.00 percent capsulated Satureja essential oil. Adding different levels of Satureja khuzistanica essential oil in conventional and microcapsulated forms to diet of broiler chickens had no effect on feed intake,FCR, immune response and the number of white and red blood cells. However, experimental treatments containing conventional and microcapsulatedformof Satureja essential oil caused a significant decrease in body weight of the birds relative to than the control treatment. The level of thyroid hormones (T3 and T4) and blood biochemical parameters (cholesterol, triglyceride, HDL and LDL) were not affected by the experimental treatments. Although small intestin histologhy traits like width of villi, depth of crypt and length of villi to depth of crypt ratio were not affected by the experimental treatments, the level of 0.5 percent capsulated Satureja essential oil caused a significant decrease in length to width of villi ratio (P<0/05). Acccording to the results of the present experiment, using of two common and microcapsulated Satureja essential oil forms, have not any effect on performance, blood biochemical parameters and immune response.

To investigate the effect of different levels of Allium ampeloprasum powder (AP) and flavophospholipol (FP) on growth performance, blood metabolites and small intestine morphology of broilers, an experiment was conducted on 200, day-old male broiler chicks (Ross 308) in a completely randomized design with 5 treatments, 4 replicates and 10 chicks per each. The treatments consisted of: corn-soybean meal as basal diet (BD), BD + 0.02% flavophospholipol, BD + 0.5% AP, BD + 075% AP and BD + 1% AP. The results showed that feed intake (FI) increased by FP treatment over all periods (P<0.01). Addition of FP, increased WG in starter phase (P<0.05). In grower and whole period the best WG and FCR was observed for FP, 1 and 0.75% AP (P<0.01) treatments. Blood glucose, triglycerides and cholesterol were decreased by AP significantly (P<0.05). Heterophil to lymphocyte ratio decreased significantly by 1% AP compared to control group (P<0.05). Villi height and villi height to crypt depth ratio increased by FP and AP supplementation (P<0.05). Based on results, 0.75 and 1% AP had positive effect on growth performance, immunity and small intestine health of broilers and with regards to restriction on the use of antibiotic in broiler ration, AP can be used to improve growth performance and immunity of broilers.
