摘　　要：Numbers of 300 day-old broiler chickens through a CRD design with 5 treatments, 3 replicates and 20 chicks in each pen were used to evaluate the effect of thyme (T), licorice (L), thyme + licorice (TL), and enzyme supplemented (E) diets on performance, immune and carcass characteristics. According to the results, performance traits, immune indices, and carcass traits in herbal medicine and enzyme supplemented diets were improved significantly than control diet (P < 0.05). Weight gain and FCR in T and E groups were significantly higher and lower than other groups respectively (P < 0.05). Internal organs such as abdominal fat and liver weight as indicators of lipogenesis rate were decreased in T, L, and TL diets than control or E diet significantly (P < 0.05). Immune organs such as burse and spleen weight as indicators of immune situation were increased in TL diet than other treatments significantly (P < 0.05). These findings indicated that thyme and licorice singly or in combination as organic herbal medicine can affect performance, carcass and immune characteristics. Also an improved immune organ such as burse or spleen in this study indicates that this herbal medicine can promote the immune situation and efficacy of health and livability.Numbers of 300 day-old broiler chickens through a CRD design with 5 treatments, 3 replicates and 20 chicks in each pen were used to evaluate the effect of thyme (T), licorice (L), thyme + licorice (TL), and enzyme supplemented (E) diets on performance, immune and carcass characteristics.
