Résumé
This experiment was performed to evaluate the effects of Thyme Extract (TE) and Thyme Powder (TP) on growth performance, carcass and organ characteristics, blood parameters, enzymes, immune system, and intestinal morphology in broilers. The experiment was performed based on a completely randomized design with 5 treatments, 4 replications and 10 Ross 308 male broilers in each replication for 42 days. Experimental treatments included aqueous extract of thyme (50 and 100 mg/kg feed) and thyme powder (150 and 250 mg/kg feed) which were used in combination with the basal diet (control). The effect of treatments was analyzed by SAS statistical software and the means were compared at 5% probability level with Duncan's multiple range test. The results showed that in the final period of the experiment, different levels of TE and TP had a significant effect on daily weight gain, feed intake and conversion ratio improvement (P
