This experiment was conducted to evaluate the effects of different levels of Nasturtium officinalis(NO)medicinal plant powder on performance, carcass quality traits, blood biochemical and antioxidant parameters of broilers from 11 to 42 days in two experimental periods: grower (11 to 24 days) and finisher (25 to 42 days). In this experiment 280 Ross- 308 broilers (male and female) were used completely randomized design with 5 treatments, 4 replicates per treatment and 14 birds in each replicate. Experimental groups included: 1) control group (without NO), 2) group with 0.5% NO, 3) group with 1% NO, 3) group with 1.5% NO and 5) group with 2% NO. The results showed that using of NO without having any significant effects in carcass quality traits, blood biochemical and antioxidant parameters, affect the performance of broilers in grower, finisher and total periods (p<0.05). In these periods, using 1% of NO powder in broilers diets improved the amount of daily weight gain and feed conversion ratio. The lowest amount of daily weight gain and the highest feed conversion ratio were observed in control group. The highest body weight was obtained with 1.5% of NO. In conclusion using 1% Nasturtium officinalispowder in broiler diets can improve their performance.
