The effects of three herbal plant powders (thyme, cinnamon and turmeric) on growth performance and ascites were studied in broilers. Eight hundred one-day-old Arian broiler chicks were randomly allocated into eight treatment groups with four replications and 25 chicks per cage. The experiment lasted for 42 days. Energy and high protein diets were used to increase the speed of growth and inducing ascites in broiler chickens. Experimental treatment groups were: control treatments, consisting of two diets with different nutrient densities (high density and low density) and two base diets were supplemented with herbal powders at a rate of 5 g/Kg of the diet in a factorial arrangement. Feed intake, BW gain and feed conversion ratio of the broilers were measured. Parameters related to ascites (thyroid hormones, hematocrit value, erythrocyte osmotic fragility and right ventricle-to-total ventricle ratio (RV/TV) were measured. Results showed that there were no influences on broilers’ growth performance. On the other hand, hematocrit value, T4, T3/T4 and RV/TV were significantly decreased by using herbal plants compared with the control, but no significant changes were observed on erythrocyte osmotic fragility (EOF) among the treatments. The results of this study suggested that herbal plants have beneficial effects in reducing ascites in broilers.

An experiment was conducted to investigate the effect of funnel and licorice on immune response, blood parameter and gastrointestinal organs in broiler chiks. A completely randomized design with six treatments, four replications and 25 broiler chicks in each replication were used. Experimental groups were consisted of 1- Basal diet without any additives (Control-), 2- Basal diet + 2.5 g/Kg funnel, 3- Basal diet + 5 g/Kg funnel, 4- Basal diet + 2.5 g/Kg licorice, 5- Basal diet + 5 g/Kg licorice and 6- Basal diet+ Antibiotic growth promoter. In this experiment, immune response as like as SRBC, immunoglobulin G and M and some blood parameters (T3 and T4) were investigated. In addition, gastrointestinal organ was investigated. According to the results, using funnel and licorice in 2.5 and 5 g/Kg of diets had no significant effect on feed intake, body weight, livability, feed conversion and production index (p > 0.05), but the numerical difference between herbal groups and antibiotic was observed. Based on these results, carcass, breast, drumsticks and abdominal fat percentage were not affected by treatments (p > 0.05). Using herbal plant and antibiotic did not alter the intestinal and immune organs weight and also its effects on duodenum, jejunum and ileum weight and length were not significant (p > 0.05), and finally similar results were observed for T3 and T4.
