J. H. Kim*, S. C. Kim** and Y. D. Ko**Korea Applied Microorganism Industrial Research*,College of Agriculture and Life Science, Gyeongsang National University**ABSTRACTThis 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 finishingpigs (50.2±1.4kg, Landrace×Yorkshire×Duroc) were assigned to 4 treatments and randomly divided into 12groups. They were divided between early finishing period (50~80kg) and late finishing period (80~120kg).Finishing pigs were fed on a basal diet supplemented with 0, 1, 2 and 4% levels of zeolite. Average daily gainand feed conversion were significantly (P
