This study was conducted to evaluate effects of mud flat bacteria origin protease supplementation on growth performance, amino acid digestibility, blood characteristics, meat quality, fecal VFA (volatile fatty acids) and NH₃-N (ammonia nitrogen) concentration in finishing pigs. Eighty pigs (Landrace ⅹ Yorkshire ⅹ Duroc, 60.08±2.69 kg average initial body weight were used during experimental period. Dietary treatments included 1) high nutrient density diet, 2) high nutrient density diet +0.1% protease. For overall period, ADG was improved in treatment of high nutrient density diet added protease compared with treatment of low nutrient density diet without protease (P less than 0.05).
