Four hundred and eight one-day old Ross 308 broiler chicks were provided one of the following experimental diets over 42 days:  a basal diet without any additives, or a basal diet supplemented with 0.1%, 0.2%, 0.4%, 0.6%, or 0.8% Miswak powder. Four replicates of 17 birds were allocated to each treatment. Neither broiler performance (body weight gain, feed intake, and feed conversion ratio) during starter (d 1-21), finisher (d 22-42), and the overall period (d 1-42) of the study, nor blood parameters (glucose, triglyceride, cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, and very low density lipoprotein-cholesterol) were influenced by experimental treatments (P > 0.05). Chicks fed diets containing 0.4% Miswak had higher (p < 0.05) cecal Lactobacillus than the control group at day 42. Furthermore, 0.6% and 0.8% Miswak reduced the number of cecal E coli compared to the control diet (P < 0.05). There were no significant differences in carcass yield and the relative weights of thigh, breast, and abdominal fat at day 42 (P > 0.05). In conclusion, we found that supplementation with Miswak powder had no beneficial effects on performance and blood parameters of broilers, but could improve cecal bacteria counts at levels greater than 0.4%.
