外文摘要：BACKGROUND: Probiotics have been used to address antibiotic alternatives and environmental concerns. This study was conducted to evaluate the effects of Bacillus licheniformis and Bacillus subtilis complex supplementation on growth performance, nutrient digestibility, faecal microflora and faecal noxious gas emissions in growing-finishing pigs. RESULTS: Dietary B. licheniformis and B. subtilis complex (B. licheniformis and B. subtilis in a 1:1 ratio) supplementation showed a linear increase (P < 0.05) in digestibility of dry matter at weeks 6, 12 and 15, a linear increase (P < 0.05) in digestibility of nitrogen at week 12, a linear increase (P < 0.05) in faecal Lactobacillus counts at weeks 6 and 12, a linear decrease (P < 0.05) in ammonia (NH 3 ) emission at weeks 6 and 12 and a linear decrease (P < 0.05) in total mercaptan emission at weeks 3, 9 and 15. CONCLUSION: Dietary B. licheniformis and B. subtilis complex supplementation increased digestibility and faecal Lactobacillus counts and decreased faecal NH 3 and total mercaptan emissions in growing-finishing pigs. ? 2018 Society of Chemical Industry. ? 2018 Society of Chemical Industry
