This study was conducted to investigate the effect of dietary supplementation of zeolite on growth performance, carcass characteristics and fecal ammonia gas release in the finishing pigs. A total of 120 crossbred finishing pigs (50.2±1.4 kg, Landrace×Yorkshire×Duroc) were assigned to 4 treatments and randomly divided into 12 groups. They were divided between early finishing period (50~80 kg) and late finishing period (80~120 kg). Finishing pigs were fed on a basal diet supplemented with 0, 1, 2 and 4% levels of zeolite. Average daily gain and feed conversion were significantly (P less than 0.05) improved by the dietary supplementation of 4% zeolite compared with other treatments during overall period.
