The effect of roxarsone (50 or 100 mg/kg) on growth performance, liver function and leg problems in broilers was studied. Ninety 2-week-old broilers were randomly allocated to the dietary treatments that contains 0, 50, 100, 200 or 400 mg/kg roxarsone, with 3 replicates for each treatment. Feeding period lasted for 5 weeks, in which roxarsone was fed for the first 3 weeks and was withdrawn for the last 2 weeks. Results indicated that roxarsone inclusion of 50 or 100 mg/kg did not significantly influence growth performance (P>0.05). Addition of 200 or 400 mg/kg significantly decreased growth and liver weight (P<0.05).
