The effects of funnel and licorice on immune response, blood parameter and gastrointestinal organs in broiler chiks

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.
