• The aim of this study was to determine the effect of using different levels of Malva powder on performance, some blood biochemical and intestinal microbial population in male Cobb 500 broiler chicks. For this reason, the four hundred one-days-old Cobb 500 strain broiler chicks were divided as an experimental randomized design plan into the four treatments with 5 replicates and 20 chicks each. The treatments were basal diet basis corn and soybean meal with no Malva powder supplementation kept as control, and 250, 500 and 700 g of Malva powder per each 1000 kg of diets respectively. During the study, the live body weight gains, feed intake and feed conversion ratio of birds were calculated weekly. At the end of the trial (6 weeks) four male bird’s form each replicates were slaughtered and dressing percentage were calculated. In addition, some blood biochemical assays and intestinal microbial population detection were evaluated. Data indicated that using of Malva powder increased feed intake, body weight gain and Pre-slaughter weight compared to the control. There significant differences (p≤0.05) for carcass traits among treatments. Data from this study showed that triglyceride, cholesterol, glucose and LDL decreased in groups fed by Malva powder (p≤0.05) supplementation. Eschechia-Coli, Klebsiella were decreased and Lactobacillus bacteria colonies were increased significantly instead (p≤0.05). In conclusion, Malva, powder supplementation may improve the performance, some carcass traits and some blood biochemical of Cobb 500 broilers chicks.
