Abstract

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.
