The effect of different levels of dried purslane powder (DPP) in broiler diets on performance, immune response and some of blood factors was studied with 160 one day old chicken Ross 308 in a completely randomized design with four treatments (diets included with levels zero (control), 2.5, 5 and 7.5 percent DPP), four replicates and 10 chicks in each replication. At 22-42 and 1-42 days different level of DPP resulted in a significant increase in the daily body weight gain and daily feed intake. Birds that were fed with five and 7.5 percent of DPP have a better feed conversion ratio compare with the control group (P<0.05). The minimum content of blood cholesterol and triglyceride was observed in birds that were fed with five and 7.5 percent DDP, respectively. DPP did not affect cellular immune response to PHA-P and antibody response to Newcastle vaccine. The total anti-SRBC titer, IgG and IgM in birds were fed with diet containing five percent DDP was significantly higher than compare with the control group on day 35 (P<0.05). The results of this experiment show that adding five percent DPP in broiler diet led to improve performance and also reduced in cholesterol and triglyceride content and improve the humoral immune.

400 one day-old broiler chicks were allocated on a randomized complete design experiment with five treatments consisting of four replications for 42 days. Experiment treatments were included: 1 . based diet consist 20 percent barley (barley control), 2 . barley control + 0.1 percent of mixed essential oil (Antibiofin), 3 . barley control + 0.2 percent organic acid, 4 . barley control + 15 ppm of antibiotic (virginiamycin) and 5 . corn-soybean based diet as corn control. In addition, Basal diet supplemented with commercial enzyme preparation. There was significant difference within treatments for 42 age's body weight and FCR. No significant differences in FI were noted among treatment during experiment. Antibody titer against (SRBC) among groups in secondly immuno response had a significant effect (P< 0.05). The villus height of deudenum and Jejunum was significant differences among the treatment groups. It can be concluded that by using additives such as medicinal plant and organic acids in diets containing barley, can be achieved to similar performance of corn based diets.
