Current research studied the replacement of monensin by propolis on performance, feed efficiency and carcass characteristic of bulls finished in feedlot. The bulls, kept in feedlot for 70 days, were allocated in three diets: Control (CON), Monensin (MON) and Propolis (PRO). They were fed on corn silage, cracked corn, soybean meal, urea, limestone and mineral salt. Further, 250 mg monensin and 35 g propolis/bulls/day were included respectively in the MON and PRO diets. Animal performance and carcass characteristics were similar (P>0.05) among diets. Feed intake was higher (P0.05) urinary excretion, microbial synthesis and carcass characteristics.
