摘　　要：为考察微生态制剂结合发酵床养殖模式对猪生产性能及猪舍环境的影响,选取400头平均体重21.57(±2.20)kg的(长×大)×杜杂交猪,随机分为4组,每组10次重复,每个重复10头猪,试验期为60 d。对照组饲喂基础日粮,传统水泥地圈栏饲养,水冲洗方式清理粪便;微生态制剂组饲喂基础日粮,饮水中添加0.1%的微生态制剂,传统水泥地圈栏饲养,水冲洗方式清理粪便;干清粪圈栏组饲喂基础日粮,饮水中添加0.1%的微生态制剂,干清粪圈栏饲养;发酵床模式组饲喂基础日粮,饮水中添加0.1%的微生态制剂,发酵床圈栏饲养。结果表明:发酵床模式组猪的生产性能和养分表观消化率提高,舍区氨气、硫化氢、悬浮颗粒的浓度和细菌总数较干清粪圈栏组降低,空气环境质量接近对照组水平。证明微生态制剂结合发酵床养殖模式可改善猪舍环境,提高经济效益。The effects of supplementing microecologics combined with feeding manners of fermentation bed（MCFB） on growth performance of pig and swine house environment were investigated. 400（Landrace × Yorkshire） × Duroc pigs（average initial BW of 21.57（±2.20）kg were randomly divided to four groups. The experiment lasted 60 days and there were10 replications per group with 10 pigs per pen. In control group, pigs were fed with basal diet and raised in cement flooring house where the manure was cleared by water. In microecologics group, pigs were fed with basal diet with 0.1%microecologics in their drinking water and raised in cement flooring house where the manure was cleared by water. In dry collection manure house（DCMH） group, pigs were fed with basal diet with 0.1% microecologics in their drinking water and raised in DCMH. In MCFM group, pigs were fed with basal diet with 0.1% microecologics in their drinking water and raised in fermentation bed house. The results showed that growth performance of pigs and apparent digestibility of nutrient increased in MCFB group. The concentration of NH3, H2S, TSP（total suspended particulate） and the total bacteria in swine house of MCFB decreased compared to those in DCMH, environmental quality of air of MCFB was nearer the level of control group. MCFB improved the environmental quality of swine house and economic benefits.
