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.

This study was conducted to investigate the effect of Mentha piperita (PP) and Melissa officinalis (MP)powder on performance, apparent digestibility of fat and protein and blood parametersof broiler chicks subjected to heat stress. 200-day-old male Ross broiler chicks were assigned to a completely randomized design with five dietary treatments and four replicates. The experimental treatments were: 1. Control group (diet without feed additive), 2. Diet supplemented with 0.5 percent PP, 3. Diet supplemented with 1 percent PP, 4. Diet supplemented with 0.2 percent MP and 5. Group supplemented with 0.4 percent MP. The experimental diets were offered to the chicks from 25 to 42 day of age. During the experiment, the birds were kept at 34°C ± 2 for 8 hours (9.00 to 17.00). The diets supplemented by Mentha piperita and Melissa officinalis powder had not significant effect on feed intake, but higher body weight gain (BWG) and lower feed conversion ratio (FCR) observed in the birds fed diet supplemented with one percent of PP. Apparent digestibility of dry matter and crude fat were not affected by the dietary treatments, but the digestibility of protein was increased (P<0.05) in birds fed on diet supplemented with one percent of PP. Dietaryinclusion of PP and MP had no effect on blood parameters. It could be concluded that addition of PP at the level of one percent of broilers diets during heat stress, improve protein digestibility and growth performance.
