| Abstract | ||
| In current experiment, to evaluate the consumption effect of two different dosages of ethanolic Tarragon leaf extract on performance, blood parameters, immune response and cecal bacterial population of broilers in comparison with growth promoter antibiotic, 192 day-old Ross 308 broiler chicks, in a completely randomized design manner having 4 treatments, 4 replicate and 12 chicks in each replicate were used. Experimental treatments were: 1) control receiving basal diet; 2) basal diet along with 0.045% Flavomycin growth promoter antibiotic; 3) basal diet along with 0.05% ethanolic Tarragon leaf extract and 4) basal diet along with 0.1% ethanolic Tarragon leaf extract for 42 days. Results showed that addition of ethanolic Tarragon leaf extract had no significant effect on performance, total protein and HDL, but significantly (P<0.05) reduced the serum triglyceride in treatment having 0.1% ethanolic Tarragon leaf extract. The antibody titers against Avian Influanza in 0.05% Tarragon leaf extract had significantly (P<0.05) increased and the 0.1 of Tarragon leaf extract has successfully reduced the cecal bacterial load of E.coli and Salmonella significantly (P<0.05). | ||
